[Method] In the research, major characters of 16 species of groups of {ndica hybrid rice and the correlation were explored in rice belts in Sichuan in 2011. [Result] The variation of chalkiness degree was the highest at 26.8%, followed by rate of head rice at 22.89%; varia- tions of head rice rate and chalkiness degree were lower at 0.72% and 2.61%. In addition, rate of unpolished rice was of significantly negative correlation with chalki- ness degree; rate of chalky rice was of extremely positive correlation with chalkiness degree and gel consistency; chalkiness degree was of significantly positive correla- tion with gel consistency; gel consistency was of significantly negative correlation with protein content; amylose content was of insignificant correlation with gel consis- tency (r=0.166 9) of the 16 hybrid groups. These indicated that gel consistency would be still high as the content of amylose grows (AC≥25%). For example, when the content of anylose in Chuanxiang 29A/Luhui 37, Kangfeng AJ6684, and Lefeng A/SR536 exceeded 27%, the gel consistency was over 80 mm in the research. [Conclusion] The research provides references for improvement of amylose content in breeding hybrid rice.展开更多

The results revealed that the pumpkin cultivars showed large variations in fruit stem length, single fruit weight, fruit length and flesh thickness, but small variations in initial flowering date. Significant, even highly significant correlations were found among the tested traits. Cluster analysis demonstrated that the 41 old Cucurbita moschata cultivars were divided into three groups, of which multiple traits of Group 1 were better than those in the other two groups. High similarities existed in three groups and the cultivars in each group. This research provided basis for selecting excellent traits and parents for the breeding of hybrids.展开更多

[Method] 39 B. juncea materials from western China were used for the canonical correlation analysis, and canonical correlations between each pair of the four ecological character (containing 18 variables) were verified, including yield characters (5 variables), caulis characters (6 variables), branch characters (3 variables) and pod characters (3 variables). [Result] Yield per plant of B. juncea in western China suffered a tremendous influence from effective pod number per plant while was not significantly affected by the total pod number per plant, seed number per pod and 1 000-seed weight; the most important character related with the yield character of B. juncea in western China was caulis character, followed by the branch character and pod character; yield characters, caulis characters, branch characters and pod characters of B. juncea in western China were closely correlated. [Conclusion] In order to improve the yield characters of B. juncea in western China, caulis characters should be focused on, followed by branch characters and pod characters; rapeseed varieties with high performance in total pod number per plant and effective pod number per plant should be chosen through the perspectives of effective branch number, plant height, pod number of main inflorescence, fruit stalk number of main inflorescence and other traits, while rapeseed varieties with high performance in seed number per pod and 1 000-seed weight should be chosen through the perspectives of beak length and other traits.展开更多

In this paper, based on the fuzzy logic reasoning method, a dynamic character assessing model for the arc welding power source was established and used to analyze the dynamic character of the welding power source. Three different types of welding machine have been tested, and the characteristic information of the electrical signals such as re-striking arc voltage, low welding current and so on of the welding process were extracted accurately by using a self-developed welding dynamic arc wavelet analyzer. The experimental results indicate that this model can be used as a new assessing method for the dynamic character of the arc welding power source.展开更多

The character analysis is achieved by the reflection of the human nature when the soldiers were temporarily living peacefully and their painful conflicts between duty as soldiers and human nature as men. Through the tragic fate of both the two executed Englishmen and the executors--two Irish men, the cruelty of the war is strongly condemned. The war mercilessly defeated the human nature cultivated through the friendship and knowing with each other.展开更多

文摘[Objective] The aim was to research and analyze characters and related correlation of indica hybrid rice containing high amylose. [Method] In the research, major characters of 16 species of groups of {ndica hybrid rice and the correlation were explored in rice belts in Sichuan in 2011. [Result] The variation of chalkiness degree was the highest at 26.8%, followed by rate of head rice at 22.89%; varia- tions of head rice rate and chalkiness degree were lower at 0.72% and 2.61%. In addition, rate of unpolished rice was of significantly negative correlation with chalki- ness degree; rate of chalky rice was of extremely positive correlation with chalkiness degree and gel consistency; chalkiness degree was of significantly positive correla- tion with gel consistency; gel consistency was of significantly negative correlation with protein content; amylose content was of insignificant correlation with gel consis- tency (r=0.166 9) of the 16 hybrid groups. These indicated that gel consistency would be still high as the content of amylose grows (AC≥25%). For example, when the content of anylose in Chuanxiang 29A/Luhui 37, Kangfeng AJ6684, and Lefeng A/SR536 exceeded 27%, the gel consistency was over 80 mm in the research. [Conclusion] The research provides references for improvement of amylose content in breeding hybrid rice.

文摘This study investigates the long-term performance of laboratory dam concrete in different curing environments over ten years and the microstructure of 17-year-old laboratory concrete and actual concrete cores drilled from the Three Gorges Dam.The mechanical properties of the laboratory dam concrete,whether cured in natural or standard environments,continued to improve over time.Furthermore,the laboratory dam concrete exhibited good resistance to diffusion and a refined microstructure after 17 years.However,curing and long-term exposure to the local natural environment reduced the frost resistance.Microstructural analyses of the laboratory concrete samples demonstrated that moderate-heat cement and fine fly ash(FA)particles were almost fully hydrated to form compact micro structures consisting of large quantities of homogeneous calcium(alumino)silicate hydrate(C-(A)-S-H)gels and a few crystals.No obvious interfacial transition zones were observed in the microstructure owing to the longterm pozzolanic reaction.This dense and homogenous microstructure was the crucial reason for the excellent long-term performance of the dam concrete.A high FA volume also played a significant role in the microstructural densification and performance growth of dam concrete at a later age.The concrete drilled from the dam surface exhibited a loose microstructure with higher microporosity,indicating that concrete directly exposed to the actual service environment suffered degradation caused by water and wind attacks.In this study,both macro-performance and microstructural analyses revealed that the application of moderate-heat cement and FA resulted in a dense and homogenous microstructure,which ensured the excellent long-term performance of concrete from the Three Gorges Dam after 17 years.Long-term exposure to an actual service environment may lead to microstructural degradation of the concrete surface.Therefore,the retained long-term dam concrete samples need to be further researched to better understand its microstructural evolution and development of its properties.

文摘A lot of experimental methods have been brought forth to assess the dynamic character of the arc welding power source, but up to now, this issue has not been solved very well. In this paper, based on the fuzzy logic reasoning method, a dynamic character assessing model for the arc welding power source was established and used to analyze the dynamic character of the welding power source. Three different types of welding machine have been tested, and the characteristic information of the electrical signals such as re-striking arc voltage, low welding current and so on of the welding process were extracted accurately by using a self-developed welding dynamic arc wavelet analyzer. The experimental results indicate that this model can be used as a new assessing method for the dynamic character of the arc welding power source.

文摘[Objective] This study was conducted to evaluate the associations of many characters of male sterile lines in Brassica napus L.[Method]10 recessive genetic male sterile(RGMS)lines were used as parents to cross in a half diallel cross method to produce 45 single cross hybrids.These 45 crosses and their 10 parents were evaluated at Guiyang during 2007-2008.[Result]The positive correlations of seed yield with plant height,pods per plant,days to flowering and days to maturity were significant.Their respective correlation coefficients(r)were 0.644,0.583,0.281 and 0.341.Highly significant and negative correlation was observed between seeds per pod and seed size(-0.533).Direct path coefficients were observed for pods per plant(0.556 2),seeds per pod(0.407 4),1 000-seed weight(0.481 3),and plant height(0.401 7)to seed yield.[Conclusion]Pods per plant,seeds per pod,1 000-seed weight and plant height were positive correlated with seed yield and showed high direct contributions to yield.Other characters including branches per plant,days to flowering,days to maturity and oil content had low contributions to seed yield.
文摘The paper focuses on the four soldiers away from the battle field depicted in the short story Guests oftke nation written by Frank O'Conner. The character analysis is achieved by the reflection of the human nature when the soldiers were temporarily living peacefully and their painful conflicts between duty as soldiers and human nature as men. Through the tragic fate of both the two executed Englishmen and the executors--two Irish men, the cruelty of the war is strongly condemned. The war mercilessly defeated the human nature cultivated through the friendship and knowing with each other.
文摘Guests of the Nation displays vividly the gravity of the tragic dilemma in which O'Connor's characters are caught,between military duty and the ancient sancta of the moral law.In this paper,the author analyzes Jeremiah Donovan,the Irish commanding officer,who is seemingly unfriendly and cold-blooded because he delivers the news of the impending executions to Bonaparte,the innocent narrator and also one of the Irish guards and it is Donovan who fires the gun at the execution.To the exterior,he is a cold antagonist who mercilessly murdered the two English hostages.However,Donovan is a character of dualities and as a victim of the war,he is a character full of contradicts.In the interior,Donovan is a character tortured by the conflicts between what is natural and what is unnatural.
文摘Load characteristics are the main factor to affect voltage stability. In addition, load modeling reflecting the actual load characteristics has been a well—known difficult problem and unsolved so far, It is mainly due to the fact that the load composition, amount and characteristics are always changing. This paper introduces the slip into the equivalent impedance load model to analyze load characteristic, the varying slip is employed to indicate?time-varying load characteristic precisely, and considering the dissimilar load behaviors, discusses node voltage, power during the changes of load characteristic, obtains voltage inflexion and power inflexion, and then analyzes the mechanism of power system voltage instability based on static voltage stability region. An example indicates the feasibility of the method.
文摘A good novel depends on the success in portraying the characters in it. In Tess of the D'Urbervilles,Tess is a beautiful country girl. In this novel,she is a new woman. She is not submissive to man and full of rebel spirit. Because she is educated,she has a strong self-respect. The more important is that after being seduced,she not only maintains her virtue but also becomes stronger. Her true and pure love for Clare drives her to break the convention and tolerate others' satire.
文摘A virtual character is a design of a fictitious creature with distinctive characteristics created by people,and Disney virtual characters are those Intellectual Property(IP)images that appeared in Disneyland and Disney movies.This investigation aimed to explore why many younger females are keen to spend money on Disney virtual characters.This paper adopted the Marketing Mix Theory strategy(product,price,placement,and promotion(4P)),and the SWOT analysis method has been utilized.This paper investigated the relationship between the 4Ps and consumers’purchasing intentions,and it turned out that unique design and effective promotion in this Disney case would promote consumers’purchase intention,while the higher price and less accessible placements affected their purchase intentions.Thus,the high price and limited places somewhat inhibit customers’desire to buy;due to the attractiveness of the product itself and the promotion on the internet,the target consumers are still willing to consume.

文摘Graphology-based handwriting analysis to identify human behavior,irrespective of applications,is interesting.Unlike existing methods that use characters,words and sentences for behavioural analysis with human intervention,we propose an automatic method by analysing a few handwritten English lowercase characters from a to z to identify person behaviours.The proposed method extracts structural features,such as loops,slants,cursive,straight lines,stroke thickness,contour shapes,aspect ratio and other geometrical properties,from different zones of isolated character images to derive the hypothesis based on a dictionary of Graphological rules.The derived hypothesis has the ability to categorise the personal,positive,and negative social aspects of an individual.To evaluate the proposed method,an automatic system is developed which accepts characters from a to z written by different individuals across different genders and age groups.This automatic privacy projected system is available on the website(http://subha.pythonanywhere.com).For quantitative evaluation of the proposed method,several people are requested to use the system to check their characteristics with the system automatic response based on his/her handwriting by choosing to agree or disagree options.The automatic system receives 5300 responses from the users,for which,the proposed method achieves 86.70%accuracy.
文摘This paper analyses the female characters in E.M.Forster’s novels from the perspective of feminism,through the deep exploration of E.M.Forster’s works,it is evident to draw a conclusion that there are four kinds of female characters:first of all,stubborn and arrogant old ladies;the second type is insensitive but self-awakening middle-aged ladies;the third type is knowledgeable and smart young ladies;the last one is the warm-hearted and benevolent lady.These four kinds of different female characters can reveal that E.M.Forster has a contradictory attitude towards women.For one thing,he respected and sympathized with women,for another he discriminated against women.
文摘Tonglin area is one ofthe areaswherethere existmany copperore deposits.The geotec- tonic property has many titles.Mostof geological scholarscall itthe lower Yangtze platform depression and divide the geotectonic stages into formation of basement,sedimentaion of coverand intreplate deformation.According to the diwa theory,this paperclassifies itas the Jiangsu- Hubei geodepressional system ofthe Central China geodepressional region.Accord- ing to the analysis of the features ofstructural layers,the geotectonic evolution of the region is divided into four stages:pre- geosyncline,geosyncline,platform and
文摘Animal farm is a political allegory novel George Orwell representative novels,with a pig's speech for the overture.It played a farm animal through the establishment of democratic revolution against human and animal kingdom generous.Without excep-tion,the original revolutionary ideal of course be distorted,discarded,replaced by a new generation of people to become a privileged class.The animal's life is even worse than ever.A little carelessness will lead to bloody repression with George Orwell in the rage of to-talitarianism.However,people in the evaluation of the thick and heavy in colors anti totalitarian ideology,but few people to explore the deeper reason behind the tragedy-people's servility.This paper tries to combine the plot of the novel,to talk about the survival, revolution,slavery to the Kingdom,which led to the collapse of the dream of 'animal Republic'.
