Although axiomatic systems and proof method for temporal logic have found so far relatively few applications in the query language modeling of temporal database and that was proved by Gabbay, et al in 1994, the model of time axes still must be built axiomatically, which owns soundness and completeness and depicts the time axes in fine grain.

尽管在1994年，Gabbay等人论证了时态逻辑的公理化系统和证明论方法是不适合于时态数据库查询语言建模的，但是仍需要通过对时间轴的公理化建模，利用公理化系统的可靠和完全等性质对时间轴作"细精度"的语义刻画。

基于此，应用有限元方法分析了转接轴静强度，并用FE-SAFEWORKS模块对转接轴进行疲劳分析，计算其寿命，从而为转接轴的设计提供一种新的思路。

The running quality of the wind tunnel power shaft system has a decisive influence on the efficiency and performance. With increase of the runtime of the shafting, rotor parts have inevitable mass eccentricity, which obviously strengthens the coupling function of torsional and bending vibration.

风洞动力轴系的运行品质对风洞的效率和性能有决定性的影响，随着轴系在役运行时间的增加，转动部分多数会有质量偏心现象出现，这使得轴系的扭转振动与弯曲振动的耦合作用明显增强。

As for the problems in the experimentation, such as the slow response speed of axes torque control, the disturbance of torque control to position control of throttle lever and the torque fluctuation of axis, solutions had been put forward and proved theoretically.

The bearing inner ring and the axis tight fit, the outer ring bearing hole is a more loose with the non-separation-type bearings installed, press the bearings can be installed on the shaft, then shaft with bearings packed together into the bearing hole inside, if the bearing is small, can also be lighter than the soft metal hammer blow set

对无油轴承内圈与轴时紧配合、外圈轴承座孔是较松配合的非分离型轴承进行安装时，可用压力机将轴承先安装在轴上，然后将轴连同轴承一起装到轴承座孔内，若轴承较小时，也可用较软的金属锤轻击套

It is widely concerned in fatigue of concrete structures. In this paper, concrete triaxial compression fatigue experiments and tension-compression fatigue experiments with constant confinements in two lateral directions have been carried out using a self-modified loading apparatus. Based on the analysis of the test data, the quantitative principles of concrete fatigue deformation and the calculation method of fatigue strength are determined.
