On the bases of these , we give computer graphics models of some basic physical variables , such as time , mass , force , velocity and acceleration , etc . . thus we can build an integrate system . then we can do some research work about the models " behavior properties , such as collision , collision response and invert kinematics , and so on 在此基础上，对经典力学中的基本物理量如时间、质量、受力、速度、加速度等进行计算机图形学建模，以期建立一个完整的理论体系，然后在这个体系基础之上研究模型的行为属性，如干涉、碰撞以及碰撞后的响应、 .关联物体的运动等。
Phopholipase c - 1 ( plc - 1 ) is widely known to play an important role in regulating cell proliferation and differentiation , development of the organisms , cell transformation and oxidative stress . till now , the mechanism how phopholipase c - 1 acts can not be thoroughly illustrated , nor has the interaction between plc - 1 pathway and other signal pathways been systematically reported . this research chose 2 - de + ms as the basic method from all kinds of proteomics strategies and compared the total protein expression map of mef genetically deficient in plc - 1 ( plc - 1 - / - ) to that of wild type mef ( plc - l + / + ) aimed to find some protein spots differentially expressed , thus we can discuss the impact of knockout of plc - 1 on signal transduction initiated by growth factors such as egf comprehensively . in this way , we can study the biological function of plc - 1 and mechanism of plc - 1 pathway indirectly , which will contribute a lot to further analysis 鉴于plc - 1发挥上述作用的机制尚未完全阐明， plc - 1通路与其他信号通路间的交联和代偿尚无系统报道，又因为以往的研究方法不够全面，本研究以野生型小鼠胚胎成纤维细胞( plc - 1 ~ ( + / + ) )和缺失磷脂酶c - 1的小鼠胚胎成纤维细胞( plc - 1 ~ ( - / - ) )为研究模型，在众多蛋白组学策略中选择了双向电泳+质谱( 2 - de + ms )作为研究手段，通过对比表皮生长因子( egf )刺激24小时后上述两种细胞的总蛋白质表达差异，全面地探讨敲除plc - 1对生长因子诱导的信号传递的影响，从而间接研究plc - 1生物学作用、信号传递机制及其代偿情况，为后续的深入研究打下基础。
The mathematical methods of theoretical analysis to determine some unknown or omitted parameters in combat efficiency theory of military aircraft based on the present models of combat efficiency of airforce equipment and the actual data of military operation are introduced in order to develop or improve the theory with practical work and some new concepts , such as combat efficiency and actual efficiency among airforce mission . for example , the combat efficiency usually comes from academic research and could be also called appraisal efficiency or static efficiency . after modified with actual data of military operation of past records which also could be seen like actual combat efficiency , confrontation efficiency and dynamic efficiency . through calculation and analysis it must be noted that the numerical value of actual combat efficiency is larger or much larger than the value of combat efficiency 通过应用现有的作战飞机空战效能的数学分析模型，在已有的历史空战实例资料数据的基础上，进一步确定或者探讨有关战效分析的数学模型中的待定因子或者假想忽略不计的参数，进而对作战飞机空战时的效能评估的研究模型作一些验证和完善性质的分析，从而提出有关战斗机空战时作战效能评估的新思路或新概念.比如，通常所理解的作战效能，也称为评估效能或静态效能，经过加权以后，形成实战效能或对抗效能，也可称为动态效能.经过计算分析，认为对抗效能的数量级别，要比评估效能的数量级别大，甚至很大
