Thus, since gain scales with drain current and power dissipation, a minimum drain current exists at which a MOSFET oscillator amplifier element supplies adequate gain for oscillation.

因增益与带漏电流和功耗成比例，一个最小漏电流会在MOS场效应管振荡放大器元件能够提供适当的增益用于振荡的时候出现。

The drain cover is available in four different finishes: bright chrome-plated, stainless steel brushed, white alpine and as a tile-bearing element.

这个渠盖在四个不同的领域可以适用：明亮的镀铬，不锈钢刷子，阿尔卑斯白，以及承重零件。

Number of cell and node in girding of finite element could be reduced by seepage element with one dimension for simulating thin and long sand-drain.

使用一维渗流单元模拟细长砂井，可以减少有限元网格中的单元和节点数。

"These products are often referred to as upgraded accounts, but if you end up paying for an element you cannot claim on, it is money down the drain, " said Sheila Nicoll, FSA director of policy.
