磁通量

The analogous unit in the cgs system is the maxwell = one erg/abampere.

韦伯：米-千克-秒单位制中磁通量的单位，为 1 焦耳/安培。

I started to derive the formula for flux with Ampere's Law...

于是就用安培定律来推导磁通量的公式。。。

Like a simple bar magnet, this field's primary magnetic flux is directed out from the core in the Southern Hemisphere and down toward the core in the Northern Hemisphere.

地磁就如同一根普通的磁铁棒，而这个磁场的主要磁通量是在南半球由地核向上穿出，并在北半球向内进入地核。

The unit of magnetic flux in the centimeter-gram-second system, equal to the flux perpendicularly intersecting an area of one square centimeter in a region where the magnetic intensity is one gauss.

麦克斯韦尔厘米－克－秒制的磁通量单位，即垂直贯穿磁强度为一高斯的一平方厘米面积区域的磁通量

When the secondary circuit is closed, both primary and secondary currents set up a flux in the core.

当次级电路接通时，初级电流和次级电流都在铁芯内建立了一个磁通量。

Faraday's law is that when the flux in the conductor loop changes, it produces electromotive force in the conductor loop, and obeys to contour integral law , Maxwell Curl Theory is that when the magnetic intensity of a certain point in ether space changes, there produces electric field at that point in ether space, which is the field mutual production theory of "electric field produces magnetic field and magnetic field produces electric field" in the free space which everybody is familiar with, and it obeys differential law , Lorentz magnetic force is that when metal electrons cut magnetic lines, metal electrons forced by move along the conductor to form inductive current, in fact, it doesn't matter whether coil moves or magnet moves, only if there exists relative motion between magnetic field and conductor, metal electrons must cut magnetic lines, which is,"coil stills while magnet moves to the left" and "magnet stills while coil moves to the right" these two situations are the same, which both belong to metal electrons having cut magnetic lines.

法拉第定律指导体环路里的磁通量发生变化时，在导体环路上产生电动势，而且服从围线积分律；麦克斯韦旋度理论指以太空间某点的磁场强度发生变化时，在以太空间的该点产生电场，即大家熟知的自由空间里"电场生磁场与磁场生电场"之互生场理论，而且服从微分律；洛伦兹磁力指金属电子切割磁力线时，金属电子受力沿着导体漂移而形成感应电流，其实，无论线圈运动或是磁铁运动，只要磁场与导体存在相对运动，则金属电子必然切割磁力线，即，"线圈静止而磁铁向左运动"与"磁铁静止而线圈向右运动"这两种情况是一样的，都属于金属电子切割了磁力线。

Magnetic flux: The flux through a surface is the integral over the surface of the normal component of the magnetic induction; expressed in webers in mks units or in maxwells in cgs units (l weber = 108 maxwells).

磁通量：某个面的磁通量为该面上磁感应强度法向分量的总合；米-千克-秒单位制中用韦伯来表示或在厘米-克-秒单位制中用麦克斯韦来表示(l 韦伯= 108 麦克斯韦)。

This thesis proposed the design and implementation of an ASIC for the motor control with DTC technology. Note that this ASIC is implemented by cell-based Design style with Verilog language.The basic principle of the Direct Torque Control is to select the switch sequence of the inverter. Those switches will control the magnetism and torque of the stator, to induce a fast response of the induction motor. Furthermore, the d-q axle's static coordinate, which is transferred from both the three-phase current and voltage, is used to compute the stator's magnetism and torque. By comparing with original values, those magnetism and torque will be calculated and set to new data. Then the switching table and the hysteresis controller are decided with the new data to generate a voltage vector and to control the stator magnetism and torque.

直接转矩控制的基本原理为经由侦测马达定子磁通与转子转速，来适当的选择变频器功率电晶体的切换状态，以获得快速且不易受外在环境影响的马达控制响应；首先，根据量测三相电流与利用变频器的切换状态取得马达的三相电压，将其转换至d-q轴静止座标，然后藉此估测马达的磁通量与转矩量，再分别与侦测的定子磁通量和转矩量比较后，得到定子磁通量与转矩量比较的结果，再利用DTC电压向量切换表(DTC Voltage Vector Switching table)，依定子磁通与转矩的比较值及马达所在的角度位置，来选择一个适当的电压向量，进而依切换顺序来激发功率电晶体，达到控制感应马达的目的。

With the precondition of not importing magnetic charge, we gave rules of magnetic flux quantization, and the relations between magnetic flux quantization, Principle Quantum Number , Angular Quantum Number , Magnetic Quantum Number and Spin Quantum Number were built.

在不引入磁荷的前提下，给出了磁通量子化规则，建立了磁通量子化与主量子数、角量子数、磁量子数和自旋量子数的联系。

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。
