The desired results for micromorphic continuum mechanics and couple stress theory are naturally obtained via direct transitions and reductions from the coupled conservation law of energy for micropolar continuum theory, respectively. The basic balance laws and equations for micromorphic continuum mechanics and couple stress theory are constituted by combining these results derived here and the traditional conservation laws and equations of mass and microinertia and the entropy inequality. The incomplete degrees of the former related continuum theories are clarified. Finally, some special cases are conveniently derived.展开更多

The current increase in the speed of natural-origin structure growth may be linked to their superior mechanical properties and environmental resilience. Biological composite structures with helicoidal schemes and designs have remarkable capacities to absorb impact energy and withstand damage. However, there is a dearth of extensive study on the influence of fiber redirection and reorientation inside the matrix of a helicoid structure on its mechanical performance and reactivity. The present study aimed to explore the static and transient responses of a bio-inspired helicoid laminated composite(B-iHLC) shell under the influence of an explosive load using an isomorphic method. The structural integrity of the shell is maintained by a viscoelastic basis known as the Pasternak foundation, which encompasses two coefficients of stiffness and one coefficient of damping. The equilibrium equations governing shell dynamics are obtained by using Hamilton's principle and including the modified first-order shear theory,therefore obviating the need to employ a shear correction factor. The paper's model and approach are validated by doing numerical comparisons with respected publications. The findings of this study may be used in the construction of military and civilian infrastructure in situations when the structure is subjected to severe stresses that might potentially result in catastrophic collapse. The findings of this paper serve as the foundation for several other issues, including geometric optimization and the dynamic response of similar mechanical structures.展开更多

Space and time have been shown in the Unitary Quantum Theory (UQT) not to be connected one with the other, unlike in the Special Theory of Relativity. In UQT, time becomes Newtonian again, and the growth of the particle’s mass with growing speed proceeds from other considerations of physics. Unlike the quantum theory, the modern gravitation theory (the general theory of relativity) is not confirmed by experiments and needs to be considerably revised.展开更多

文摘Using the Skyrme density functional theory,potential energy surfaces of^(240)Pu with constraints on the axial quadrupole and octupole deformations(q_(20)and q_(30))were calculated.The volume-like and surface-like pairing forces,as well as a combination of these two forces,were used for the Hartree–Fock–Bogoliubov approximation.Variations in the least-energy fission path,fission barrier,pairing energy,total kinetic energy,scission line,and mass distribution of the fission fragments based on the different forms of the pairing forces were analyzed and discussed.The fission dynamics were studied based on the timedependent generator coordinate method plus the Gaussian overlap approximation.The results demonstrated a sensitivity of the mass and charge distributions of the fission fragments on the form of the pairing force.Based on the investigation of the neutron-induced fission of^(239)Pu,among the volume,mixed,and surface pairing forces,the mixed pairing force presented a good reproduction of the experimental data.
文摘The authors discuss contradictions between the principal branches of the modern physical picture of the universe. Space and time have been shown in the Unitary Quantum Theory (UQT) not to be connected one with the other, unlike in the Special Theory of Relativity. In UQT, time becomes Newtonian again, and the growth of the particle’s mass with growing speed proceeds from other considerations of physics. Unlike the quantum theory, the modern gravitation theory (the general theory of relativity) is not confirmed by experiments and needs to be considerably revised.

文摘Objective:To explore the clinical effect of the method of Liangxuesanyu stasis on the patients with severe pneumonia and its mechanism.Methods:From March 2018 to October 2019,60 patients who met the diagnosis criteria of severe pneumonia were selected from the Department of critical medicine,Affiliated Hospital of Nanjing University of traditional Chinese medicine.They were divided into 30 Chinese medicine groups and 30 control groups according to the random number table method.Patients in both groups were given conventional Western medicine treatment such as anti-infection,phlegm elimination,nutritional support,and respiratory support.Patients in the Chinese medicine group were added Liangxuesanyu Granules(shuiniujiao 20g,zhidahuang 10g,taoren 10g,shengdi 20g,mudanpi 10g,chishao 15g,danshen 20g),Wash with warm water to 200ml,and take 100ml orally or nasally each morning and evening.The course of treatment is 14 days.The differences in respiratory function,inflammatory response,and mortality at 28 days were compared between the two groups of patients before and on the 7th and 14th days after treatment.Results:The oxygenation index(PO2/FiO2)of the Chinese medicine group was significantly higher than that of the control group at the 7th day after treatment(P<0.01).The tracheal intubation rate,Murray score,WBC,TNF-α,and PCT were all lower than those of the control group.(P<0.05);On the 14th day after treatment,the oxygenation index(PO2/FiO2)of the Chinese medicine group was higher than the control group(P<0.05),the TNF-αwas lower than the control group(P<0.05),and the Murray score was significantly lower than the control group(P<0.01);The mechanical ventilation time of the Chinese medicine group was lower than that of the control group(P<0.05),and the length of hospital stay and 28-day mortality were not significantly different from those of the control group(P>0.05).Conclusion:The intervention of Liangxuesanyu method in the treatment of severe pneumonia can effectively reduce the inflammatory response of patients,improve the oxygenation level and reduce the time of mechanical ventilation.
文摘Rural revitalization strategy is an important topic in China.As an important platform for the implementation of the strategy,the preparation of village planning for traditional villages is conducive to coordinating the contradiction between protection and development,and promoting the sustainable development of traditional villages.The traditional villages of the Jingmai Mountain in Pu’er,Yunnan Province are taken as the research objects.The first-hand data are obtained through interviews and field research,and Actor-Network model is used to analyze the actors’ goal and obstacle in preparation of village planning,which better reflects the interests of different actors in village planning process.At the same time,the action path of planning is interpreted through the process of problematisation,interessement,enrolmen,mobislisation and dissidence.In the preparation of village planning for traditional villages,key elements should be paid attention to,such as bridging the cognitive gap,building consensus,setting up participation platform and formulating relevant policy guarantee mechanism,etc.
文摘Under the background of stereotyped urban planning and construction and the pursuit of high land value,it is particularly important to explore the application of urban environmental characteristics in urban design and highlight the integration of local characteristics and people’s life.In this paper,based on the origin of Fengshui theory and the planning points of an ideal Fengshui pattern,the planning and design of Shengming Kangyuan Area in Liyang were studied to explore the positive influence of Fengshui theory in the construction of urban space,and some planning suggestions were put forward to improve the urban environment and achieve harmony and unity between man and the natural environment.
文摘An review of the similarities and disparities on the ideas of translation between Lin Yutang’s translation principle and German Functional School’s Skopos Theory finds that,for the three rules in both theories,two rules which involve fidelity and smoothness/coherence share some similarities.Though both Lin and Skopos Theory argue that fidelity and smoothness/coher?ence are significant indicators for translation,their focus and priority are not identical.Lin stresses the importance of beauty while Skopos Theory focuses on the skopos of the translation.Lin’s translation rules are more suitable for literature translation,while Skopos Theory is more popular among those who conduct instrumental translation and documentary translation.
