望远镜

The dew shield is retractable, and the cap is a press fit.

它还配有可伸缩的遮光罩和黑色按压配合的镜头盖——从审美角度讲我真觉得这架望远镜漂亮极了。

In order to get the largest possible field of view, low magnification eyepiece multi-use wide-angle eyepiece, depending on the field in general is greater than 3 °, FPA Office for aiming with the reticle with its optical axis to remain parallel with the primary mirror optical axis.

通常为口径小于10厘米的折射望远镜。为了得到尽量大的视场，目镜多选用低倍率的广角目镜，视场一般大于3°，焦平面处装有供瞄准用的分划板，它的光轴要与主镜光轴保持平行。

You see,I have been searching the moors with my telescope,and although I have not actually seen the pris on er,I have seen the pers on who is taking him food.

您是知道的，我一直在用我的望远镜搜寻这些沼地，而且虽然我没有真正地看到过那个罪犯，但是我已经看见了给他带饭的那个人。

How do we determine our binoculars used by the prism of the material it ?

我们如何判别我们所使用的双筒望远镜的棱镜的材质呢？

Rectal examination may reveal disorders such as internal piles (these may require proctoscopy using a small telescope device - see Haemorrhoids), ano-rectal abscesses, polps and especially cancers of the rectum.

直肠指检可能揭示出疾病，如内部桩（这些可能需要proctoscopy使用小型望远镜装置-见痔疮），年度直肠脓肿， p olps，尤其是癌症的直肠。

The function is the most strong currently of admire Bo telescope have already can prognosticate to 15,000,000,000 light years far galaxy.

目前功能最强大的哈勃望远镜已经能观测到150亿光年远的星系。

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。

No. 3372 of the "telescope sun hat", but also innovative design and development of proprietary products.

编号为3372的"望远镜太阳帽"，也是创新设计开发的专利产品。

To the sky, and he had seen there evidence enough to overthrow Aristotle and Ptolemy together.

他是第一个把望远镜对准天空的人，观察到的论据足以把亚里士多德和托勒密一起推翻。

He had been the first to turn a telescope to the sky, and he had seen there evidence enough to overthrow Aristotle and Ptolemy together.

他是第一个把望远镜对准天空的人，观察到的论据足以把亚里士多德和托勒密一起推翻。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
