And the key technology is providing a proper simulated target. Play the LCD panel on the focal plane of the collimator,to display the real-time figure formed by the simulation software.With the light shining on the LCD panel,the collimator forms a simulated target with a infinite distance.

本课题研究主要内容是：提出了用计算机控制的数字仿真目标设计思想，以液晶光阀替代传统成像平行光管的分划板，并实时显示计算机生成的各种图形；在外光源的照射下，平行光管将液晶光阀显示的图形成像于无穷远，提供给被测光电跟踪测量设备。

2 Axis squirter inspection system for complex composite panels on Joint Strike Fighter Aircraft.

15+2轴喷水检测系统用于&联合攻击战斗机&复杂复合材料板，可同时控制10轴用于复杂曲面的跟踪。

Ln this paper, a set of welded seam tracing system of the structural laser and the CCD vision which is applicable for thick plate is studied.

研制了一套适合大厚板结构激光和CCD视觉的焊缝跟踪系统。

The left phototransistor is turned on, causing a signal to turn the motor continuously until the shadow from the plate returns the tracker to state B. As the day slowly progresses, state C is reached shortly, turning on the right phototransistor.

左光电是开启的，造成了一个信号，使电动机的阴影不断，直到从板返回跟踪到B国随着时间慢慢进步， C国达成不久，把右边光电。

METHODS: Non-derivatised cuvette immobilised Lipid A was used to track the bonding between the Lipid A and aqueous extracts and alcoholic extracts from seventy-eight TCM, and then neutralized endotoxin in vitro by selecting hypso-bonding TCM that removed the tannins.

将革兰阴性细菌的脂质A包被于生物传感器的非衍生板建立靶点，跟踪测定赤芍、大黄、黄芩等78种中药的水提物和醇提物与Lipid A的结合活性，再将筛选出的中药去鞣质后与定量的内毒素（LPS，20、50ng·ml^-1）37℃孵育30min后，测定孵育后的样品与Lipid A的结合情况，以评价样品内的活性物质含量。

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。
