下标 max约为975°/s。零速投种和排种轮线速度以及播种机进给速度都有关系，但若取适当的行程速比系数，则基本可实现零速投种，仿真获得该系数为42。

In this thesis, terahertz transmission properties through three kinds of simple sub-wavelength metallic structures, including single sub-wavelength metallic circular hole, single sub-wavelength metallic slit and double sub-wavelength metallic slits, are experimentally investigated in the far field by using our own THz time-domain spectroscopy system and are theoretically analyzed. Conclusions are obtained as follows:(1) a single sub-wavelength metallic circular hole exhibits the same terahertz transmission properties as that of round metallic waveguide, which are influenced by the diameter of circular hole and the thickness of metal foil.

本文利用本实验室搭建的太赫兹时域光谱系统研究了太赫兹波段金属亚波长结构的透射特性，其中对三类金属亚波长简单结构即单个金属亚波长圆孔、单个金属亚波长狭缝和金属亚波长双缝的太赫兹透射现象进行了远场探测以及理论上的分析，得到了以下一些成果：(1)太赫兹波通过单个金属亚波长圆孔的传播现象与圆形金属波导具有相同的规律，其特性受到圆孔直径和金属箔厚度的影响。

Current peaks for different spins in the Ⅰ-Ⅴ curve split. The confined"light"hole energy levels of the QW turn out to be an effective tunnelling channel for both"heavy"and"light" holes. Although considerable tunnelling current originate from the"heavy"hole state in the emitter region, the current in the collector is mainly carried by the"light"hole state.

无论对重空穴还是轻空穴来说，量子阱中轻空穴的束缚能级都是有效的隧穿通道，虽然隧穿电流有相当大比例由发射极重空穴态提供，但在集电极端大部分电流又由轻空穴态传导。

Also need a cover, but according to the technical requirements of spine of the three marks at the dacpot cannot be parisand, and the books even more difficult to back-office fibroarthrosis endpaper, its main function is the book after the mysteriouses book page on four spine can be started to draw an irregular trapeziform hole, the role of the hole to be capable of a four-page books turned up sufficiently to the size of the hole should be determined depending on the thickness of the books, too big or too small affect book reading efficiency.

封面同样需要过胶，但按工艺要求书脊处的三条痕线内不能有胶水，更不能和书内页的书脊处粘连，它的主要作用是书成型后，掀开书页时在封四书脊处可拉开一个不规则的梯形孔，这个孔的作用能使书本的封四页充分打开，孔的大小应视书本的厚度决定，过大或过小都将影响翻书阅读效果。
