On the other hand, the influence of Absurd drama manifested mainly in the perspective of observing the world in later plays. Absurd drama reveals the uncertainty of the world by the skill of"simile way". Contemporary playwrights draw extensively and broadened the use of"simile way", and create the new simile symbols: anti-classic simile, anti-system simile and anti-meaning simile. At the same time they use a comprehensive simile to create a kind of sensual drama.Absurd drama also destroys the language function of traditional drama by rupture and desegregation, also tends to use "the language of no meaning," to reflect the world's essence. The contemporary generation create a physical theatre to expulse of the role of language. Another extreme is to strengthen language function thus creating a language game.

另一方面，荒诞派戏剧的影响力主要体现在后世剧作对客观世界的认知上：荒诞派通过&直喻&的手法来表现世界不确定性的本质，被后世剧作家广泛借鉴并且拓宽了直喻手法的使用，出现了反经典、反系统和反深度的直喻符号，同时另一个极端则是用剧场性的全面直喻创造了具有震撼力的感官戏剧；荒诞派通过破裂与解体的方法化解了传统戏剧的语言功能，更倾向于用&无义的语言&表达来体现世界的无义，后世剧作家在此基础上索性彻底驱逐了语言的作用从而创造了肢体戏剧，另一个极端则是强化语言功能创造了&语言游戏&。

Former coursebook evaluations were almost carried on by specialists, scholars or teachers. And the evaluation was a kind of impressional one. There is absence of objective evaluation with learners as evaluators in the area of Chinese coursebook for foreigners evaluation research and practice. In addition, there are a great deal of Chinese coursebooks, but they are not the same high level in quality, which also calls for a reasonable coursebook evaluation as a way of scale to judge Chinese coursebooks and improve the quality of coursebooks.

以往的对外汉语教材评估，其评估主体大部分是专家、学者或教师，且进行的多为印象性评估，在对外汉语教材评估研究和实践领域缺少的是让学习者参与的客观性教材评估；此外，当今对外汉语教材虽数量繁多却良莠不齐的现状，也要求有科学的对外汉语教材评估作为衡量的手段和方式来甄选教材和改进教材质量。

Incurrent research, aiming at the rupture problem engendered in the shooting process of acertain 5.56mm automatic rifle, the strain and stress distributions on the cartridge caseunder the action of axial pull have been analyzed. Based on the theories of elastic-plasticmechanics and contact mechanics, a mathematic and physical model of the cartridge-caseand chamber system has been set up; and based on the platform of the general softwarepackage APDL of ANSYS for finite element analysis, a parameterized model of thecartridge-case and chamber system has also been established. The method for nonlinearFEA has been adopted to analyze the stress distribution on the entire cartridge-case andchamber system, and the method of contact element has been employed to investigate thecontact stress between the cartridge case and chamber, and then the influences of frictioncoefficient and locking space on the static and dynamic stress and strain response of thecartridge case and chamber to the action of power gas have also been discussed. On thebasis of a lot of numerical tests, a kind of element Plane13, which is concentrated incoupled computation of heat and construction, has been used finally to simulate thetransient response of the cartridge-case and chamber system to the power gas. Throughloading the temporary thermal characteristics of explosive gas in the procedure of emulate, the corresponding transient thermal stress distributed on the entire system under thecombined load of transient thermal stress and transient pressure has been obtained. Owingto these comprehensive considerations, the numerical results obtained in this paperrepresent the actual situations comparatively exactly.
