This is due to the resistance of the skin being inversely proportional to the frequency of the stimulation.

这是因为皮肤的电阻和刺激器的频率成反比。

The forward problem is solved using a finite element technique in two dimensions that is a foundation of the inversion problem.

正演计算是电阻率反演成像的基础，本文从二维有限元基本理论出发，完成了高密度电法的二维有限元正演模拟程序，为后期多方法反演奠定了基础。

S1 is then changed to position 1. The voltage stored on C1 is inserted between the output and inverting input of the amplifier and the output of the amplifier changes by VIN to maintain the amplifier input at the input offset voltage. The output then changes from (VOS + IbiasR2) to (VIN + IbiasR2) as S1 is changed from position 2 to position 1. Amplifier bias current is supplied through R2 from the output of the amplifier or from C2 when S1 is in position 2 and position 1 respectively. R3 serves to reduce the offset at the amplifier output if the amplifier must have maximum linear range or if it is desired to DC couple the amplifier.

接着 S1 拨到位置 1，使 C1 的电压加在放大器的输出端和反相输入端之间，(由于电容端电压不能突变，所以)输出端的电压将产生大小等于 VIN 的变化，使放大器输入端维持输入失调电压，即当开关 S1 从位置 2 拨到位置 1 时，输出端电压将从(VOS + IbiasR2)变为(VIN + IbiasR2)。S1 处于位置 2 时，放大器的偏置电流是由输出端经电阻 R2 提供的，当 S1 转向位置 1 时则由 C2 提供。R3 的作用是降低输出失调电压，如果要求放大器具有最大的线性范围，或者采用直流耦合，就应该使用该电容。

Because of this, the current will flow resistance of ion exchange resin.

因为这样的电阻较小，电流会流过离子交换树脂。

The leakage resistance is due to the insulator of the ionization chamber and the coax cable.

泄漏电阻是由电离室和同轴电缆的绝缘体引起的。

But in our model the electron scatteringpotential, chemical potential and ionization degree are obtained self-consistently,except the ion structure factor.

与Al的实验电阻率结果比较，等离子体的温度低于40eV时，计算结果与实验符合得很好，但温度高于40eV，则低于实验值。

Smoke Detection Circuit C The smoke comparator compares the ionization chamber voltage to a voltage derived from a resistor divider across VDD.

烟雾检测电路C的烟雾比较器比较电离室电压从整个VDD的电阻分压器产生一个电压。

In this example, there are two sets of switches: one set of two-pole switches (two Model 7702 modules) is used to connect the cells to the voltmeter, and one set of isolated switches (two Model 7705 40-Channel Control Modules) is used to connect the load resistors.

在本例中有两组开关：一组为双刀开关（两个7702模块），被用来将电池连接到伏特计；另一组为隔离开关（两个7705型40通道控制模块），被用来连接负载电阻。

According to the basic principle of telluric current prospecting and general formula of derived subsurface leakage, three dimensional distribution of relative errors about the earth resistivity and plane isopleth map were put forward,with the maximum value of leakage current allowable by" The Technical Specification on Geoelectric Observations".

根据电法勘探的基本原理。参考已推导出的线对地漏电的基本公式。给出了《地电观测技术规范》允许漏电电流最大值时的电阻率相对误差三维分布图及平面等值线图，并讨论了其分布特征

The resistivity decreases under high pressure due to the increase of one-electron bandwidth and the enhancement of the itineracy of eg electrons.

在整个压力范围内由于高压导致单电子能带展宽，增强电子的巡游性，使电阻率降低。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
