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。

Chapter 3 is to investigate the control design of switched dissi-pative Hamiltonian system with finite number of subsystems.

At first the structures of the face harmonic motion drive of separate tooth are analyzed. Its principle of work is given. And simple chart of dynamic mechanism without superfluous constraints is established according to contact and junction of components each other.

首先介绍了散齿端面谐波齿轮传动的结构，分析了其工作原理，根据各构件间的相互接触和联接情况建立了传递动力、无多余约束合理的机构运动简图。

Presently, this new model drive has not been researched. Therefore, the basically theoretical research on the face harmonic motion drive of separate tooth and application is not only developed new type of active teeth drive but also has a definite theoretical significance and economic value.

目前，这种新型的传动方式国内外还没有进行研究，因此，关于散齿端面谐波齿轮传动的基础性理论研究和开发应用，不仅增加了活齿传动的类型，具有一定的理论意义，而且具有很好的应用前景和经济价值。

Before I begin my harum-scarum day--grinding away at thse books it does me so much good to come and have a steady walk with our comfortable friend.

在我开始一天荒唐的工作之前，也就是说在死抠那些书本子之前，先到这儿来跟我们这位称心的朋友慢慢地散会儿步，这对我有很大好处。

I can not make it blossom and suits me
