试述傅作义的军事思想

傅作义作为我国现代史上一位名的爱国将领，在40多年的军事生涯中，形成了丰富而完整的军事思想体系。以兵为本是他军队建设的立足点；加强思想政治工作是他军事建设的主线；根据不同情况实施不同的战略战术是他军事思想的重要组成部分。在这一军事思想的指导下，傅作义领导和参与领导了长城抗战，缓远抗战，忻口会战，五原大捷等一系列对日作战的重要战役。为粉碎日本侵略“西进北犯”的企图起了重要作用。     

蠕变条件下完整岩石的起裂和扩展准则

The mechanism and criterion of crack initiation and propagation of rocks were investigated by many researchers,And the creep behaviour of rocks was also theoretically and experimentally studied by some scientists and engineers.The characteristics of crack initation and propagation of rocks under creep condition.however,are very improtant for rock engineering and still not paid enough attention by researchers,In this paper,the criterion and mechanism of crack initiation and propagation under creep condition were investigated using specimens collected from sandstone rock formations outcropping in the Emei Mountain,the Sichuan Province of China.Cuboid specimens under three point bending were used in this investigation.All specimens were classified into four sorts and used for Mode-I fracutre of creep frcture tests.The experimental result shows that due to creep deformation.rock crack will inevitably initialt and propagate under a load of KI,which is less than fracture toughness KIC but not less than a constant(marked as KIC2),KIC2 indicates the ability of rock to resist crack initiation and propagation under creep conditions and is less than fracture tough ness KIC.defined as creep fracture toughness in this paper,KIC2 should be considered as an importnat parameter on design and computation of rock engineering.The microstructureal mechanism for crack initiation and propagation of rock materials under creep condition was introduced based on competitive model between softening effect and hardening effect,and the validity of test result was explained.The test result was also verified in rheological theory.When KI is more than KIC2 but less than KIC,rock crack will initiate and propagate after a time interval of sustained loading under creep condition.In order to find the relation between duration of sustained lading.which can lead to crack initiation and propagation,and the initial stress intensity factor KI,an unequal0interval time sequence forecasting and predicting model was introduced,and the relation was obtained for homogeneous and isotropic fine-grained red sandstone.Finally a modified fracture toughness formula was given,in which the influence of fracture process zone(FPZ) was fully considered.     

Interpreting the Rules: Language and Transformation in a Boys’ Comprehensive

This essay emerges from my position as a new trainee teacher, entering my first school, a school as unique and also as typical as any. What struck me was the complexity of the school's culture (and counter-cultures). Language was revealed as a site of resistance, a clash between staff and pupils at the point of instruction; a reluctance to read or write; an unanticipated response to text. This resistance was often shut down, yet it must at some level be meaningful. Indeed, it was often clearly communicated to me by the boys' complaints about having to read the texts prescribed to them, or indeed in the depth of the creative responses, particularly to visual images, that many of them displayed when given the opportunity to write in class. This suggests the need for a broader understanding of the way language is used, the different registers employed by pupils in interactions in the classroom; and, for me in my new role as teacher, the challenge of how to harness those moments which enable students to explore expression in ways they find meaningful.     

What is normal,true, and right: a critical discourse analysis of students’ written resistance strategies on LGBTQ topics

This study examines how students perform resistance to lesbian, gay, bisexual, transgender, and queer topics in their written reflections in a higher education diversity course. Using a three-tiered critical discourse analysis , this article maps students’ resistant textual devices in their written reflections, analyzes the institutional setting of the course, and examines how the larger social discourse plays an important role. Findings suggest that students engage in resistance and (re)produce oppressive discourse in part due to the institutional and larger social discourse of the course and the topic. Implications suggest the need to promote to course instructors how language can (re)position students in a place of privilege.

穴位组织的力学性能及行针过程针体所受阻力分析

在针刺过程中根据不同区域组织的结构和性质,给出了不同的生物力学模型：表皮无血管无神经,致密而坚硬,可以看作类固体;真皮及皮下结缔组织中血管神经等分布广泛,疏松而柔软。是典型的软物质。从杨氏弹性模量、压缩系数、动摩擦系数等方面对表皮的力学性质进行了研究分析,同时对结缔组织中具有代表性的物质胶原纤维和弹性纤维的力学性质进行了研究分析。结果表明提插法行针主要阻力来自表皮,“得气”后的主要阻力可能来自结缔组织收缩;捻转法行针主要阻力来自胶原纤维和弹性纤维的缠绕。弹性纤维独有的热力学性质在传递针刺能量中可能起着重要作用。
