Value varies from different counties, which is the main cause of the conflict and misunderstanding in communication between China and western countries. It is first introduced in this paper about how these differences are formed and then explain them in several ways. It is of great significance to know and learn the cultural differences in cross-cultural communication.展开更多

It is distributed widely in the Qaidam Basin, western China, a hyperarid inland basin located in the northern Tibetan Plateau. Pores in the brine storage medium act as storage space and transmission channels of underground brine. Therefore, the porosity of brine storage medium determines its ability to store brine. In this study, Mahai Salt Lake was used as the research area as a modern saline lake located in the north area of the Qaidam Basin. A total of 100 porosity samples were collected from eight sampling points in two profiles of the research area at sampling depths of 1.30–314.78 m. The porosity distribution characteristics and influencing factors in brine storage medium were analysed according to the measured porosity data. Based on analysis of the pore structure characteristics, the brine storage medium contains intercrystalline pores, unlike conventional freshwater storage mediums. Moreover, the primary salt rock is susceptible to dissolution by lighter brine, facilitating the formation of secondary porosity. Due to the formation of secondary pores, a porosity greater than 20% remains even at buried depths greater than 100 m. Based on the geological statistical analysis, due to the geographic location, salt formation time, and depositional environment, the porosity values of Mahai Salt Lake do not exhibit a wider distribution, but also show more extreme values than a nearby salt lake. Based on the porosity characteristics by depth, due to the presence of secondary pores, flooding, stratigraphic static pressure, and other factors, porosity shows fluctuations with increasing depth.展开更多

Most types of fractures increase as bone density declines. But most of the knowledge about causes and prevention of fractures comes from studies performed in Western countries. Asian women appear to have similar or slightly lower bone density that may be a result of their smaller size. They appear to have a lower risk of hip fracture than Whites, which may be a result of their shorter hip axis. The risks of other types of fractures in Chinese women is less well defined and reasons for differences in the rates of osteoporotic fractures between China and Western countries remain to be explored. A study is underway in Beijing to describe the risks and potential causes of fractures among older women in urban China. Randomized trials in Western countries have demonstrated that calcium and vitamin D, estrogen, calcitonin,or bisphosphonates can reduce the rate of fractures. Increased intake of calcium and vitamin D may be the most effective approach to preventing fractures in China, but this should be tested in a randomized trial.展开更多

Capitalism has intensified the rich-poor divide and power politics have led to great upheavals. Western values have caused a "value dislocation" for non-Western countries. The world is calling for new development concepts. The "Belt and Road" initiative has emerged as an answer. It embodies China's ideas on global development. First, it works for the "common prosperity" of every country, which will ease contradictions between the South and the North. Second, it emphasizes geo-economie integration that will heal the fragmentation of Eurasia. Third, it advocates linkages between people and inclusiveness to create a new kind of civilization. However, many difficulties and challenges lie ahead for the implementation of the "Belt and Road" initiative.展开更多

The summer circulation anomalies associated with the SNAO give further confirmation of the above relationship. In a positive-phase (negative-phase) SNAO year, there is an anomalous cyclone (anticyclone) over central East Asia, which can increase (decrease) the total cloud cover over this region. Such changes of the total cloud cover can then decrease (increase) the solar radiation reaching the surface, which is consequently unfavorable (favorable) to the formation of EHEs over northern China.展开更多

It is suggested that growth rate is regulated by growth hormone. The objective of the current study was to analyze the porcine growth hormone (p GH ) gene polymorphisms based on the polymerase chain reaction restriction fragment length polymorphism method (PCR RFLP) for three western meat type breeds (Duroc, Landrace and Pietrain) and two local Chinese pigs (Meishan and Jiangquhai). Five polymorphic restriction sites were detected with the Apa I, Msp I, Bsp I and Hha I restriction enzymes in two amplified fragments (605 bp, -119 to +486; 506 bp, +206 to +711). Breed difference was found only in the 506 bp fragment. There was no difference in allelic frequencies of Bsp I and Hha I restriction sites among the five breeds ( P >0.05). Landrace and Meishan pigs lacked allele G 3 of Msp I site. The allele G 3 frequency of restriction Msp I site of the 506 bp fragment in Pietrain pigs was higher than that in Duroc and Jianquhai pigs ( P <0.001). For Apa I site, the Meishan pigs lacked allele G1 ; no difference was found in allelic frequencies among Pietrain, Duroc, Landrace and Jiangquhai pigs ( P > 0.05 ). This new and rapid PCR RFLP typing method is an attractive tool for analysis of porcine growth hormone gene restriction sites. The differences in Msp I and Apa I restriction sites may explain the growth difference between the foreign meat type breeds above mentioned and local Chinese pigs.展开更多

The incidence of NPC is higher in Southern China and Southeast Asia compared with Western countries. Given its high radiosensitivity, the standard treatment for NPC is radiotherapy. However, radioresistance remains a serious obstacle to successful treatment. Radioresistance can cause local recurrence and distant metastases in some patients after treatment by radiation. Thus, special emphasis has been given to the discovery of effective radiosensitizers. This review aims to discuss the biomarkers, classified according to the main mechanisms of radiosensitization, which can enhance the sensitivity of NPC cells to ionizing radiation.展开更多

The distance coefficients of reasonable and existing landscape indexes of farmland shelterbelt networks were com-puted, and then through the classification of the distance coefficients, and the establishment of evaluation rules, the spatial heterogeneity of farmland shelterbelts was evaluated. The method can improve the evaluating system of previ-ous studies on shelterbelts distribution, resolve the disadvantages of lacking spatiality of overall evaluation, and make the evaluation results have more directive significance for shelterbelt management. Based on this method, spatial het-erogeneity of shelterbelt networks was evaluated in the midwest of Jilin Province, China. The results show that the re-gions with fewer shelterbelts and no closed network account for 34.7% of the total area, but only 4.9% of the area has relative reasonable pattern of shelterbelt networks. Many problems exist in the distribution pattern of shelterbelts, therefore, much attention should be paid to construct farmland shelterbelts in the study area.展开更多

In the scenario of global warming, mountain ecosystems change rapidly, especially in the arid region of northwestern China. This paper provides an assessment of the changes in temperature and precipitation in the historical records of climate on the northern slopes of the eastern Tianshan Mountains. A Mann-Kendall nonparametric trend and Sen's tests are employed to analyze the interannual changes and innerannual variability in temperature and precipitatiofi in the regions of low to high altitude. The present study finds that the largest increases in annual temperature are observed at stations in the low altitude regions. The significant increasing trends in temperature tend to occur mainly in late winter and early spring at stations from middle to high altitude, but in summer and autumn at stations of low altitudes. The increasing trends in annual precipitation are found from the middle to high altitude areas, but decreasing trends are found in the low altitude areas. The significant increasing trends in precipitation occur mostly in winter and earlier spring at stations from the middle to high altitudes, while the increasing and decreasing trend coexists at stations of low altitude with most of the significant trend changes occurring in March, June and August.展开更多

It focuses on the visual process, artistic feelings, and beauty of form as its creative core. The Chinese Cursive Calligraphy (草书), on the other hand, aims to create a vibrant beauty resulting from sweeping wrap-around and continuous changes. It also pays attention to the personality stretch, the lyrical and expressive, and the abstract beauty within images. In both arts, there is a rhythmic beauty running through the works, allowing the charm of lines to fully express the artist's creative thoughts and feelings, making them stand out impressively.展开更多

In the decadal SST changing experiment, a prominent sea surface cyclone anomaly occurred west of the Northwest Pacific warming SST. The cyclone anomaly is conductive to anomalous rising motion and more rainfall over the Northwest Pacific and southeast coast areas of China, but less rainfall in central China. Caused by the only aerosol concentration increasing, the change of climate in East Asia is totally different from that induced by the regime shift of SST around 1976/77 with the same model. The sulfate and black carbon aerosol concentrations were doubled respectively and synchronously in East Asia(20?–50?N, 100?–150?E) to investigate the climate effects of these two major aerosol types in three experiments. The results show that, in all three aerosol concentration changing experiments, the rainfall during boreal spring increases in North China and decreases in central China. It's worth noting that in the DTWO experiment, the rainfall diminishes in central China while it increases in the north and southeast coast areas of China, which is similar to observations. From the vertical profile between 110?E and 120?E, it is found that sulfate and black carbon aerosols first change the temperature of lower troposphere owing to their direct radiative effect, and then induce secondary meridional circulation anomaly through the different dynamic mechanisms involved, and at last generate precipitation and surface temperature anomalous patterns mentioned above.展开更多

Major reasons are the decline of US-led Western developed economies' global influence; US and other Western countries inaction or ineffective actions; power diffusion allowing non-state actors to intervene; a global governance short of needed rules; and mainstream economic theory's overemphasis on market roles. International disorder is a long-term process posing a potential threat to China's national interests. The situation challenges China to create an international economic and trade order, thereby shaping itself as prophet of global free trade, shaper of international economic and trade rules, and trendsetter for globalization.展开更多

Breed difference was found only in the 506 bp fragment. There was no difference in allelic frequencies of Bsp I and Hha I restriction sites among the five breeds ( P >0.05). Landrace and Meishan pigs lacked allele G 3 of Msp I site. The allele G 3 frequency of restriction Msp I site of the 506 bp fragment in Pietrain pigs was higher than that in Duroc and Jianquhai pigs ( P <0.001). For Apa I site, the Meishan pigs lacked allele G1 ; no difference was found in allelic frequencies among Pietrain, Duroc, Landrace and Jiangquhai pigs ( P > 0.05 ). This new and rapid PCR RFLP typing method is an attractive tool for analysis of porcine growth hormone gene restriction sites. The differences in Msp I and Apa I restriction sites may explain the growth difference between the foreign meat type breeds above mentioned and local Chinese pigs.

In 1996, China' s academic disciplines have been made an adjustment, " industrial economics" become the first place of secondary discipline which under the first discipline " Applied Economics " in the category of" economics" , has achieved the initial connection with international conventions in the disciplines set. However, in the study, research methods, main content, or in the theoretical basis and the theoretical system, there is a big difference between the Western industrial economics and the domestic industrial economics.
文摘The Western Abstract Painting has a dynamic, constantly-changing, and non-entity beauty. It focuses on the visual process, artistic feelings, and beauty of form as its creative core. The Chinese Cursive Calligraphy (草书), on the other hand, aims to create a vibrant beauty resulting from sweeping wrap-around and continuous changes. It also pays attention to the personality stretch, the lyrical and expressive, and the abstract beauty within images. In both arts, there is a rhythmic beauty running through the works, allowing the charm of lines to fully express the artist's creative thoughts and feelings, making them stand out impressively.

文摘In this study, we used the NCAR CAM3.0 model to study the climate effects of both decadal global Sea Surface Temperature(SST) changing and the increasing aerosol concentration in East Asia in boreal spring. In the decadal SST changing experiment, a prominent sea surface cyclone anomaly occurred west of the Northwest Pacific warming SST. The cyclone anomaly is conductive to anomalous rising motion and more rainfall over the Northwest Pacific and southeast coast areas of China, but less rainfall in central China. Caused by the only aerosol concentration increasing, the change of climate in East Asia is totally different from that induced by the regime shift of SST around 1976/77 with the same model. The sulfate and black carbon aerosol concentrations were doubled respectively and synchronously in East Asia(20?–50?N, 100?–150?E) to investigate the climate effects of these two major aerosol types in three experiments. The results show that, in all three aerosol concentration changing experiments, the rainfall during boreal spring increases in North China and decreases in central China. It's worth noting that in the DTWO experiment, the rainfall diminishes in central China while it increases in the north and southeast coast areas of China, which is similar to observations. From the vertical profile between 110?E and 120?E, it is found that sulfate and black carbon aerosols first change the temperature of lower troposphere owing to their direct radiative effect, and then induce secondary meridional circulation anomaly through the different dynamic mechanisms involved, and at last generate precipitation and surface temperature anomalous patterns mentioned above.
文摘Since the 2008 international financial crisis, international political and economic disorder has become obvious. Major reasons are the decline of US-led Western developed economies' global influence; US and other Western countries inaction or ineffective actions; power diffusion allowing non-state actors to intervene; a global governance short of needed rules; and mainstream economic theory's overemphasis on market roles. International disorder is a long-term process posing a potential threat to China's national interests. The situation challenges China to create an international economic and trade order, thereby shaping itself as prophet of global free trade, shaper of international economic and trade rules, and trendsetter for globalization.
