4 Of the nominal size DN ≥ 200 of the valve, the valve cover can be processed in a screw, after trial, must be plugged with metal plug screw.

4.3.4对公称尺寸DN≥200的闸阀，可在阀盖上加工出一个螺孔，试验完毕后，必须用金属螺塞堵塞。

The trapped charge screening effect of poly-Si film is also observed when the devices with large defect densities.

另外，我们观察到了缺陷密度对於闸极电压和通道厚度之间的关系有很大的影响。

However, all of the charges stored in the conventional floating gate NVM will leak back to substrate because the tunnel oxides have leakage paths during operation processes. It is even worse when being scaled down. Therefore, the thickness of tunnel oxide is difficult to scale down in terms of charge retention and endurance characteristics.

然而传统浮动闸极记忆体在操作过程中，穿遂氧化层产生漏电路径会造成所有储存电荷流失回到矽基版，随著尺寸微缩这种情况会更糟，所以在资料保存时间和耐操度的考量下，微缩穿遂氧化层的厚度是非常困难的。

This paper puts forward safety strategy algorithm after analyzing safety strategy used in artificial scheduling.

本文在分析了人工调度中使用的安全策略后，提出倒闸操作的安全策略算法。

Then the fault forecast in mine hoist to steel wire rope wears away degree, get empty to move time, brake shoe wear away life, brake shoe clearance, remnant presses and brake disk deflection degree adopt Wavelet neural network in this paper, which have the important meaning to guarantee the mine hoist circulate efficiently safety.

因此本文采用小波网络对提升机钢丝绳磨损度、空动时间、衬垫磨损寿命、闸瓦间隙△、残压Pc、制动盘偏摆度δ进行故障预测。对保证矿井提升机安全和高效运行具有重要意义。
