Basically, the prototype consists of three basic modules namely light source, eyepiece as well as an optical scanning module and among all of them, light source module which contains laser lights is the most bulkiest one and good news now, the company has able to bring its size down significantly by one thousandth to merely 350gram as compared to predecessor design without impacting its image quality.

基本上，原型三个基本单元组成，即光源，目镜以及光学扫描模块和它们之间的一切，光源模块，它包含了激光灯是最bulkiest之一，现在好消息，该公司能够实现它的规模下降了千分之一显着仅仅三五〇克前任相比，在不影响其形象，优质的设计。

Three types of cuticular thickening at the polar region of the guard cells are observed: slight cuticular thickening; rod-shaped culicular thickening and rarely T-shaped thickening.With data obtained from the former research and personal observation, the cladistic methods were employed for the phylogenetic analysis of data and trees were rooted byout-group comparison using, the related genus Kadsura. as result, a new system of the genusSchisamdra Michaux was reconstructed, and Schisandra Michaux was subdivided into 2 subgenus, 3 section, 2 series 10 species in this dissertation.

Based on analysis of solution structures, growth units of CMTC crystal are determined to be formed by HgS〓 and CdN〓 tetrahedra structural units linked by -S=C=N- bond bridges and the growth units vary in dimensions with the supersaturation of growth solutions.

由溶液结构的测试结果推断出CMTC晶体的生长基元是以HgS〓和CdN〓配位四面体为基本单元，经-S＝C＝N-桥连接组成的网络结构，并且随溶液过饱和度的变化生长基元的维度也随之改变。

First the conception of switched—current technology is introduced in this paper,and then an analysis of errors in SI—memory cell is given.The resolvents which aimed at the errors mentioned above are provided.At last,a new improved circuit is given.

首先介绍了SI技术，然后以SI电路基本单元为例，分析了SI电路存在的各种误差，并针对这些误差提出了解决方法；最后提出了一种新的改进电路。

For the present work, we pointed out that, as the basic unit for classical electromagnetic field, electromagnetic element-wave should be a new kind of matter which can also be called "quasi-photon".

今天，我们还特别指出：&电磁基波&作为经典电磁场的基本单元，应该是一种新的物质，亦可称作&准光子&。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
