准直望远镜

Then threekind of hard X-ray space telescopes, namely the collimator, the rotating col-limator and coded aperture mask telescopes, are introduced. Finally the softX-ray imaging telescope is introduced.

然后分别介绍了三种类型的硬X射线空间望远镜，包括准直型、旋转调制型和编码孔径型望远镜，最后简略介绍掠入射型软X射线成像望远镜。

In plotting scene, the invention connects fiber-optic gyro(1) with full station instrument telescope(3) by adaptor(2), and make optical fibre gyro can follow full station instrument telescope simultaneously do 180 degree turning reel full station instrument cross shaft, respectively on two horizontal positions of east and west direction of gyro axis that differ by 180 degree; each horizontal position process 2 x 2 position gyro data acquisition on full station instrument perpendicular tray that differ by 180 degree; using formula to count out full station instrument collimation axis true azimuth, survey station meridian convergence angle, then can obtain full station instrument collimation axis grid azimuth, realize full station instrument orient.

基于光纤陀螺的全站仪组合定向方法是一种应用于测绘工作的基于光纤陀螺的全站仪组合定向方法，该方法在测绘现场，把光纤陀螺(1)通过连接装置(2)与全站仪望远镜(3)固连，使光纤陀螺(1)可随全站仪望远镜(3)绕全站仪横轴(4)同步做180度转动，分别在陀螺轴东西向相差180度两个水平位置，每个水平位置在全站仪竖盘相差180度的两个竖直位置进行2×2位置陀螺数据采集；利用公式算得全站仪视准轴真方位角、测站子午线收敛角，即可进一步获得全站仪视准轴坐标方位角，实现全站仪定向。

Two T3 He and D3He reactions are chosen for generating the neutrons. The neutron beam is collimated with the multiplex shielding system. The source intensity is monitored by the proportional counter or semiconductor proton recoil telescope. The neutron response curves of ST-401 scintillators with thickness from 0.16mm to 2.00mm are measured versus neutron energy. The uncertainties of experimental results are discussed in detail.

选用T3He反应和D3He反应作为中子源，子源，中子束流采用复合屏蔽体进行准直，源强采用正比计数管和半导体望远镜进行监测，实验测量了厚度从0.16mm到2.00mm的八种规格薄闪烁体的能量响应曲线，对实验的结果的不确定度进行了分析。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
