测距仪

AbstractThe dissertation discusses the principle of automatic instrument for measuring standing long jump, and its development and realization in detail.

本文讨论了立定跳远自动测距仪的原理、开发过程和实现结果。

The selectable equipments are rotor mast aiming system, two pods with 2 TOW missiles for each, Blackhole infrared suppresser, two pods with 2 Stinger missiles or other types of air-to-air missiles for each, FLIR system for pilot, AN/APR-39(V-1) radar warning system, fuel tank on hardpoints, advanced avionics and mission equipments.

旋翼轴瞄准具可将视频信号输给飞行员的电视显示器。旋翼轴瞄准具备激光测距仪。为了不被敌人发现，"防御者"Ⅱ直升机可借助旋翼轴瞄准具在树木或地形后面进行隐蔽悬停，而且还能观察战场远处的情况。只要稍作改装，就可安装为OH-6A研制的标准轻型航空电子设备。

Finally, we added a GPS, a laser telemeter and an electronic compass on serial lines.

最后，我们还在串形总线上加上了一个GPS，一个激光测距仪，一个电子罗盘。

With piezoelectric transducer, and AT89C52 one-chip computer as controller, design of software and hardware for ultrosonic telemeter is finished.

采用压电式超声波换能器，使用AT89C52单片机作为控制器，完成了超声波测距仪的软硬件设计。

Therefore, it is very important to designa good ultrasonic rangefinder.

因此，设计好的超声波测距仪就显得非常重要了。

Atkins, a wine salesman and father of one, says his wife is happy to tromp through fog-shrouded forests with him, but only ifhe leaves his range finder at home.

Atkins是一为酒销售员，一个孩子的父亲，他说他妻子很乐意同他一起穿越那些云雾缭绕的森林，但只要把他那测距仪留在家里。

The Wild GAKI Gyro Attachment is very useful, in any weather and at any time of the day or night, when it is necessary to establish a reference bearing at stations which have been fixed by arc intersection of distances, or by trilateration, with the electronic distance measuring instrument, Wild D1 50 Distomat.

Wild GAKI 陀螺附件在很多天气下，以及白天和黑夜的任何时间都是很有用的，这时，必须要建立一个支承在站台处基准，这些站台已经用距离的弧交叉，或用电子测距仪（Wild D1 50 Distomat）三边测量而固定。

Today's superb Japanese camera lenses, for example, are the end result of wartime research into range finders.

例如，现如今那些很棒的日本摄影镜头就是战时测距仪研究的结果）。

This article introduces the designing principles and characters of laser range finders of pulse-phase type,which is developed by application of GaAs-As semiconductor lasers,and ananlyses the experimental results.

本文介绍了应用砷化镓半导体激光器研制的脉冲相位式激光测距仪的设计原理和特点，并对实验结果进行了科学的分析。

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。
