Researched results indicated that contact force's modification was very little inner joints of synchronize Mechanism under the state of no-load and heavy load of sizing press, the rolling force that slab deformed created was supported mostly by side Mechanism.

研究结果表明，调宽机在空载和工作两种状态下，同步机构各构件间的运动副内接触力变化不大，侧压机构主要承受了板坯变形产生的轧制力。

Thus, the spherical-crown and saddle-shaped surfaces were demonstrated. Consequently, the basic rules and key technology of bending forming using plasma arc in practical work were obtained and the application level of the flexible forming using plasma arc had been further improved. The effects of the main parameters including power, scanning speed, scanning distance and scanning sequence had been investigated.

对成形中出现的棱角效应进行了机理分析和数值计算，结果表明棱角效应是板材沿扫描线方向受几何约束产生了较小的压应变及在扫描线上、下表面的收缩量不同所造成；提出了通过分段扫描解决棱角效应的方法，明显提高了成形质量。

Safety valve is designed for emergency safety relief and shall not be used as an operating control.

安全阀用于危机状态下的安全泄压，不应该作为操作控制的工具。

His weight sagged heavily against her, and all at once it was a corpse that she embraced, there in the black rain.

他的重量压在她身上，死沉死沉，下一秒钟，她环抱着一具尸体，站在黑色的雨中。

A sahib has got to act like a sahib; he has got to appear resolute, to know his own mind and do definite things.
