瞄准仪

Experimental results show that the proposed method is fast, stable and accurate, and the measuring accuracy of the modified CCD laser autocollimator is improved from 2 arcsec to ±0.25 arcsec in 0.23 s using the proposed method.

实验结果表明，该定位方法稳定性好，定位精度高且实时性强，应用该方法改进后激光CCD自准直仪的测量精度由2"提高到±0.25"，且单次测量时间小于0.23 s，可满足激光CCD自准直仪在小角度测量和瞄准跟踪等领域的高精度实时测量需求。

This was to become known as the AGLT collimator.

这是AGLT瞄准仪的显著特征。

Surface of the huge collimator would have seemed flat, had he been able to focus long enough.

若当时他能瞄准足够远，那他想必离thrusters很近，近到足以使这巨大瞄准仪的表面看上去是平的。

If the collimator cross hair does not center or does not lie at all in the video window, the additional optics

如果瞄准仪的十字叉丝不在中央或者不在全视场，附带的自准直光学系统可依靠测微螺旋来调节。

The weapon operator aims at the target through X12 sight of TV goniometry, and keeps the cross hairs of the sight on the target until the missile hits the target.

武器操作员通过X12型TV瞄准具测角仪瞄准目标，而且保持瞄准器的交叉瞄准线在目标上直到导弹击中目标。

A automatic collimating method with vibrating slit for the photoelectric automatic refractometer with high precision was introduced in this paper and geometry size relation of width among image and vibrating slit and amplitude was described also.

介绍了一种用於高精度光电自动折射仪并采用振动狭缝瞄准的自动瞄准方法，说明了影像宽度、振动狭缝宽度和振幅之间的几何尺寸关系。

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。

In Dresden where camera production had been dominant, civilian products and development were gradually discouraged in favor of those products such as bombsights which met the more immediate goals of the government.

在照相机主产地德累斯顿，民品生产逐渐减少，代之以当时BANNED更迫切需要的产品，如轰炸机瞄准仪等。

Other defense projects included gyroscope-based and other complex control systems for gun and bombsights and inertial navigation under Charles Stark Draper's Instrumentation Laboratory, the development of a digital computer for flight simulations under Project Whirlwind, and high-speed and high-altitude photography under Harold Edgerton.

Aim and Methods\ Three methods are analysed and compared for measuring the lateral deflection of gun bore axis from firing plane and the deviation of the sight line from the barrel axis, according to the results measured in practice. Results\ The tested data show that this new method is accurate.

引 言在多次火炮总装测量检查中，我们发现用炮口瞄准仪测量&炮膛轴线偏离射面的偏离角&与&瞄准线偏移&和用经纬仪、炮口坐标尺测量这两个项目有一定的差别。

It is also known as one of the most poisonous naturally occurring substances.

它也被称为一个最自然发生的有毒物质。

The greatest stress is found at the location on the cross section where V is the largest.

最大应力出现在横截面上V为最大的地方。
