This paper stressed on the fact that electric displacement vector is a supplementary physical element,focused on a difference between D and D surface integral and on the condition of D=ε_0E_0 existence,and made a comprehensive and correct understanding for beginner.

着重说明了电位移矢量D是一个辅助物理量，强调指出D与D的面积分的意义不同，以及D=ε0E0成立的条件，从而使初学者对D建立起一个全面和正确的认识。

In a this tube pair of deflection plate, besides demonstration electron under electric field role deflection movement, but also played causes the beam convergence the function, if causes two deflection plates the electric potentials to be lower than the acceleration extremely electric potential approximately 30 volts, then the focusing condition is best.

该管内的一对偏转板，除了演示电子在电场作用下的偏转运动外，还起了使电子束会聚的作用，如使两偏转板的电位低于加速极电势约30伏，则聚焦状态最佳。

Introduced in '55 as an affordable alternative to the Les Paul's carved-top luxury, the Gibson Les Paul Junior Electric Guitar - a one-pickup, flattop cruisin' machine - caught on quickly and climbed right into guitar legend.

简介：介绍在'55作为对Les保罗的雕刻上面豪华的一个付得起的选择，-一提取，平顶cruisin'机器-迅速风行和爬的Gibson Les保罗小辈电吉他入吉他传奇。

Among them Al_(11)La_3 photograph is accumulated as a result of lesser cathode face, to quickening its all round of magnesian matrix corrode do not remove apparent effect; and area of cathode of lumpish Al_8LaMn_4 photograph is larger, form small couple to corrode with matrix, quickened matrix corrode.

其中Al_(11)La_3相由于较小的阴极面积，对加速其四周镁基体的腐蚀不起明显功能；而块状的Al_8LaMn_4相阴极面积较大，和基体构成微电偶腐蚀，加速了基体的腐蚀。

As a grain refinement technique of outside physical field, electric modification treatment is researched by a lot of physicist and metallurgist at domestic and overseas. It has an important effect on manufacturing finished products and semi-finished products. At the same time, it foreshows huge market foreground.
