However, the pseudo-triaxial strengths of several rocks from the best fitting solutions have great scatterness from the real magnitudes. Also, it does not correspond to the experimental results that rock has the same strength under conventional triaxial compression and tension; the maximum increase of strength from intermediate principal stress has a linear relation with the minor principal stress; and the first-order derivative of strength has an interruption at the peak point.

此外，统一强度理论认为岩石三轴伸长强度与常规三轴压缩强度相同，在最小主应力恒定时中间主应力引起的强度最大增加值随最小主应力线性增加，且强度关于中间主应力的一阶导数在峰值点是不连续的，这些都与试验结果不能完全协调。

本文以双排异径球式回转支承为例，对球式回转支承在承受轴向载荷和倾翻力矩时的滚动体轴向正压力大小、分布及由高强度螺栓与主机连接的滚圈接触面的接触力进行了详细的理论推导和实际计算，说明在双排球式回转支承的结构静力分析过程中，可以将滚圈安装接触面的接触力简化为铅垂方向的均布载荷。

As the maneuverability of the model of 800 t ship with double tail fins didn′t meet the design standard,this article turned the twin skeg of the models into tail-shaft strut,and then made tur-ning tests and Z shape tests.

针对某一采用双尾鳍形式的800 t级排水船在进行自航模试验时出现操纵性能不能满足设计要求的情形，文中将其尾部的双尾鳍改成轴支架，并在某露天操纵性水池中，对改进后的自航模进行了回转和Z形操纵试验，通过对实验结果进行比较发现合理设计轴支架的大小和安装位置能够较好地改善800 t级排水船的操纵性能，并能够满足给定的船舶操纵性能设计要求。

For SOV energized to counterclockwise drive shaft rotation, reconnect the actuated part to the other end of the drive shaft.

当电磁阀励磁，需要使输出轴向左回转时，只要把输出轴的另一端与被驱动体连接即可。

Relatively speaking, the drawing for tube with fixed short plug technology would reduce the difference of the residual stress between inside and outside of the tube, and increases its uniformity.

外模半锥角对固定短芯头拔管材的轴向残余应力具有显著的影响；当半锥角为12 时，拉拔后管材的轴向残余应力值较小且分布均匀。

The off-axis reflection system composed of four aspheric mirrors was designed, but the system structure was not so simple and the performance can also be improved, besides, manufacture and test for large aspheric mirrors are difficult; and then the spherical Fresnel mirror which is easier to be manufactured and tested was used to replace the aspheric mirror, the spherical Fresnel mirror has low cost of replication, but this design also can\'t be used in projection lens because it was only feasible in narrow wavebands; Furthermore, the design making use of catadioptric projection lens was accomplished, this design is greatly applied in rear projector because it has merits of both refraction and reflection. But it had difficulties in color aberration correction and had complex structure.

设计了四片非球面组成的离轴式反射系统，然而，仅采用非球面设计系统结构不够精简，性能也有待进一步提高，且非球面面形较大时加工和检测都存在一定的困难；继而提出了用球面Fresnel反射镜代替非球面的设计方法，虽然Fresnel反射镜加工和检测更为简单，且复制成本低，但对波长具有选择性；进而，应用折反系统结合的方式设计了离轴式投影镜头，该方法因兼具折射和反射的优点，在大屏幕超薄背投系统的设计中广为应用，缺点是会产生难以校正的色差，且结构复杂。
