We also confirm that the main leakage path locates at the gate and source/channel overlap region.

另外我们也确认了在氧化层崩溃后主要的漏电路径是产生在闸极与源极或通道的重叠区域。

Experiments results show the gate controllability is increasing with channel number from single channel to ten strips multiple channels.

由一系列的实验结果发现，闸极的控制能力是随著通道数目的增加而变强。

This phenomenon could be relaxed using the SONOS structure, thanks to the thin ONO layer between the control gate and the channel.

所幸这是可以使用介於控制闸与元件通道之间薄的ONO层之SONOS 元件结构来缓和这个现象。

In the past, the Donghu lake was connected with Yangzi river, the Donghu channel, sluice gate and pumping station are all the convenience conditions for the leading river,.

历史上东湖和长江相通，现仍有东湖港沟通东湖与长江，东湖港、武丰闸和泵站等现有条件都为东湖自长江引水创造了有利的基本条件。

These improvements are attributed to the Schottky barrier height increase and the decrease of the gate to channel distance as Pt sink into the InGaP Schottky layer during gate sinking process.

这些特性上的改善源自於Schottky barrier height的增高；在退火后，因为铂扩散下沈的制程，使得闸极至通道的距离减低。

7 Gate valve according to Table 6, the main component material selection, supply and demand any special requirements by mutual agreement in order the contract.

4.15.7闸阀主要零件材料可按表6选取，如有特殊要求经供需双方协商在订货合同中注明。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
