- The high quality GaN was grown by metal organic chemical vapor deposition (MOCVD).We used Ni/Au as a schottky gate and Ti/Al/Ti/Au as a drain source of GaN MESFET. 我们利用了镍/金双层金属作为闸极的萧基接触电极，钛/铝/钛/金等多层金属作为汲极与源极的欧姆接触电极，比较在汲极与源极使用不同的合金条件下，制作出特性较佳的元件。
- The SMU provides four functions in one instrument: measure voltage, measure current, source voltage and source current. SMU在一台仪器中提供四种功能：电压测量、电流测量、电压源和电流源。
- Planar Radiation Pattern Comparison only for Consistent Source Current Direction, Field Polarization, and Field Plane. 作平面场型比较之电流源方向、电磁场极向、及场平面均必须一致。
- This is because different digital I/O boards have different sink and source current requirements. 这是因为不同的数字的输入/输出电路有不同的潭和源流行的需要。
- Higher amplitude of the oscillation results in lower drain source voltage level at which the MOSFET turns on correspondingly lower switching losses and higher efficiency of the system. 更高幅值的振荡导致场效应晶体管更低的漏源极开通电压幅值来产生更低的开关损耗和更高的系统效率。
- This method is similar to the current-reversal method except that the measurements are alternated between a fixed source current and zero current. 这种方法和电流反向法类似，只是这种方法在固定的源电流和零电流之间交替进行测量。
- Generally, such instruments can simultaneously source voltage and measure current or simultaneously source current and measure voltage. 一般地说，这种仪器能够同时输出电压、测量电流以或者同时输出电流、测量电压。
- The value of the unknown resistance is computed from the sense voltage (VM), the voltage across clamping resistor (VSH), the known value of RSH, and the source current. 未知电阻的数值可以由取样电压（VM）、钳位电阻器上的电压（RSH）、已知电阻值（RSH）和源电流计算出来。
- Cold switching is always preferable to ensure maximum relay life. Cold switching involves turning the source current off (placing it on standby) before opening or closing a relay. 冷切换更适合确保继电器具有最长的寿命。冷切换需要在开路或闭合继电器之前将源电流关闭（将其置于待机状态）。
- We design and complete a multi-frequency source current module, applying the Direct Digital Synthesis (DDS) technology. We use the DSP chip as our controller and the frequency, phase and amplitude of the signal are all programmable and adjustable. 设计并完成了多频恒流源模块,采用了直接数字合成(Direct Digital Synthesis,DDS)技术,应用数字信号处理器(DSP)作为控制器,实现了频率、相位和幅值均动态可调。
- That maths exam I took was a regular brain drain. 绞尽脑汁的数学测验，我真是绞尽了脑汁。
- Electrometers can measure high resistance either by sourcing current and measuring voltage or by sourcing voltage and measuring current. 静电计能够测量高值电阻，其方法可以采用加电流测电压，也可以采用加电压测电流。
- At the same instant, Q3 sources current into R4 through D1, thereby pulling the voltage on R4 to a diode drop below the supply voltage. 与此同时，Q3的源电流通过D1流到R4，从而拉动R4的电压，使二极管电压降到低于电源。
- The news comes from a reliable source. 这消息来自可靠的来源。
- Pull (out) the plug and let the water drain away. 拔掉塞子，把水放掉。
- They are digging trenches to drain the water off. 他们正在掘沟排水。
- They are digging trenches to drain the water away. 他们正在掘沟排水。
- The coffee grains plugged up the kitchen drain. 咖啡渣堵塞了厨房的排水道。
- The drain is blocked and needs unplugging. 排水管堵塞了，得疏通一下。
- zero gate voltage source current 零栅电压源电流
