The system adopts forecast of grid current and feed-forward of grid-voltage.

系统采用并网电流的预估和电网电压前馈控制，防止了直流过压，实现了网侧电流正弦化且为单位功率因数。

In fact, even without a ground loop, a little noise current always flows through every interconnecting cable (ie, it is impossible to eliminate these currents entirely).

事实上，即使没有接地回路，几乎没有什么噪声电流总是流经每个互连电缆（即，就不可能消除这些电流完全）。

The mere presence of this ground loop current is no cause for alarm if your system uses properly implemented and completely balanced interconnects, which are excellent at rejecting ground loop and other noise currents.

仅仅存在这种接地回路的电流是没有引起恐慌的，如果你的系统使用适当执行，并完全平衡的互连，这是极好，在拒绝接地回路及其他噪声电流。

In order to elucidate the effect of membrane stretch on ionic currents, we employed the whole-cell patch-clamp technique to investigate the effects of different kinds of stretch on voltage-dependent calcium currents in antrial circular smooth muscle cells of the guinea-pig.

The pulse power supply consists of three-phase half-wave thyristor rectifier and IGBT chopping circuit.

该电源采用三相半波晶闸管整流电路，IGBT进行直流斩波；根据电流电压反馈信号计算偏差，进行数字PI调节获得恒流、恒压输出特性；控制系统通过20mA电流环异步串行通讯接口与人机界面交换数据。

Without these phenomena, can disconnect the output side of the current transformer and DC side of the Hall Voltage Sensor current detection, reset after the operation to see if there were flow phenomenon.

如果没有这些现象，可以断开输出侧的电流互感器和直流侧的霍尔电流检测点，复位后运行，看是否出现过流现象。

The difference of the two modes is adding the secondary coil at the magnet of the closed-loop sensor. The Hall part measure the magnetism voltage difference state of the measured current and the secondary current.

磁补偿式与直测式的区别在于其铁磁体上另加一平衡绕组，霍尔器件仅检测被测电流和平衡绕组中电流在铁磁体中所产生的磁电势的平衡状态。

Maxwell's equations group in fact was already found in the basic experimental laws of electromagnetic phenomena, as well as a single magnetic pole does not exist on the facts and the integrated displacement current assumptions, using an international system of units, these equations can be written as: DivDW =ρ or DW =ρ(1) kiDivBq = 0 or Bq = 0 (2) kiCurlEBq =- Zt or × EqkZ =- BqZt (3) ZCurlHDWDW = jE Zt, or × HW = jE Zkt (4) Z-type in the Curl, and Div were vector operator curl and divergence, Micro-k points for the Hamiltonian operator, in the rectangular coordinate system,= iZZEkx jEy kqz, iE, jE, kq along Zx, y, z-axis unit vector, a vector for any AW are × AW = CurlAW, kAW = DivAW; DW for the electric displacement, Bq for the magnetic induction intensity, Eq, and HW, respectively i field and electric field strength, jY for the conduction current density,ρ the charge density for free.

麦克斯韦方程组实际上是当时已发现的电磁现象的基本实验定律以及单个磁极不存在的事实和位移电流假设的综合，采用国际单位制，这些方程式可写成：DivDW＝ρ或DW＝ρ（1）kiDivBq＝0或Bq＝0（2）kiCurlEBq＝－Zt或×EqkZ＝－BqZt（3）ZCurlHDWDW＝jE＋Zt或×HW＝jE＋Zkt（4）Z式中Curl和Div分别为矢量算符旋度和散度，为哈密顿微k分算符，在直角坐标系中，＝iZZEkx＋jEy＋kqz，iE，jE，kq是沿Zx、y、z轴的单位矢量，对任一矢量AW有×AW＝CurlAW，kAW＝DivAW；DW为电位移，Bq为磁感应强度，Eq和HW分别为电i场和磁场强度，jY为传导电流密度，ρ为自由电荷密度。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
