Further more, the fracture possibility is analyzed with fracture mechanics after the stress calculation of local high stress area around the bolt hole in shell flange and the measurement of fracture toughness of gray cast iron. The improving structure of bolts connected head and shell flange is brought forward.

此外，在计算获得缸体法兰螺栓孔局部高应力区的应力水平后，由断裂力学分析发生脆性断裂的可能性，并提出烘缸缸体与缸盖联接结构的改进方案。

The flatness quality problems such as sidewise bending and warping usually appear in hot rolled sheet product. Residual stress distribution of hot rolled steel sheet before and after straightening was obtained by modified hole–drilling technique, in order to improving the quality of hot rolled steel sheet product.

本文针对热轧钢板产品常出现的旁弯、翘曲等板形质量问题，通过盲孔法测量钢办矫直前以及粗矫、精矫后的残余应力分布来分析矫直工艺对带钢残余应力分布的影响，以便改善热轧钢板产品的质量。

This paper focuses on the evenness problem which occurs after solving the blockage problem through using bubble plate to replace sieve plate.

重点研究了采用泡罩板取代筛板解决堵塞问题后出现的均匀性问题，多方案优化的结果是采用较大直径的泡罩，并且加装一块大孔均布板，可以满足稳定运行的要求。

With the increase of gas rate of tray holes the velocity of liquid phase on plate only increases a little between caps.The clear liquid height was measured by communicating pipe. The results indicate that the distribution of liquid height is different from traditional trays. The clear liquid height increases with the liquid flow and the height of weir, and decreases with the increase of the gas rate and then return. The gradient of liquid level of CTST is less than that of sieve plate.

应用连通法对立体传质塔板的板上清液层高度进行了系统的测量，结果表明：立体传质塔板的板上清液层高度的分布和传统塔板的分布不同；其板上液层高度随溢流强度和堰高的增大而增大，随板孔气速的增加先降低后又有所回升；与筛板相比较，CTST的板上液面梯度是较小的。
