In chapter three, we study the lower orientable strong radius and strong diameterof the Cartesian product of graphs and prove that: srad(G_1×G_2)= 2r(G_1×G_2),sdiam(G_1×G_2)≤min{sdiam(G_1)+sdiam(G_2), 2(G_1×G_2), 4r(G_1×G_2)}. Furthermore,we establish three sufficient conditions for sdiam(G_1×G_2)= 2d(G_1×G_2)holds and determine the values of the lower orientable strong diameters of somespecial graphs. Moreover, we give the exact value of SDIAM, a lowerbound for SDIAM, an upper and lower bound for SRAD andSRAD, respectively.

The SCVFV(the convection-diffusion difference scheme based on control-volume face values) scheme was put forward. The theory of the SCVFV scheme was systematically elaborated. The general interpolation formula of the SCVFV scheme was given. The formulas of the SCVFV scheme based on the Cartesian coordinate were derived. The precision, the mass conservation property and the preventability of the false-diffusion of the SCVFV scheme were theoretically analyzed.

A tolerance analysis procedure based on homogeneous transform and Monte Carlo Simulation is proposed in this research. The propagation of variation in 3-D space is treated as propagation of errors during transformations of Cartesian frames, which are set up on the Key Characteristic Points.

通过定义车身装配坐标系统，根据微分运动的原理，建立了计算车身零部件位姿关系的数学模型，对典型公差语义的数学表达进行了研究；并应用蒙特卡洛模拟，对关键特征点偏差传播的统计特性进行了分析。

Must not the only fruitful renaissance be the one that reawakens the impulse of the Cartesian Meditations: not to adopt their content but, in not doing so, to renew with greater intensity the radicalness of their spirit, the radicalness of self-responsibility, to make that radicalness true for the first time by enhancing it to the last degree, to uncover thereby for the first time the genuine sense of the necessary regress to the ego, and consequently to overcome the hidden but already felt naivete of earlier philosophizing?

在近代，对一个完全有活力的哲学的渴望，已经引起了一个又一个文艺复兴，唯一富有成果的文艺复兴难道不就是唤醒笛卡尔式《沉思》的推动力吗？——不是要用那些内容，不这样做，而是以更大的强度去重新实现这些精神的彻底性、自身负责的彻底性，通过提升到最后的程度上去把彻底性第一次真正实现，于是去第一次揭开必须回退入我思『ego cogito』的真正含义，最终去克服早期做哲学的朴素性（——这已经被感到了，但依然隐藏着）。【英p5/3，德p47/2
