When the Tycho Uprising began in 2062, the universal right to read soon became one of its central aims.

当第谷环形山起义于2062年发生时，全民阅读权很快就成了起义的中心目标之一。

Most of the craters on the near side are named for famous figures in the history of science such as Tycho , Copernicus , and Ptolemaeus .

大部分的环形山对近在身旁，命名为知名人物的历史，科学等tycho，哥白尼和托勒密。

Results: IVUS revealed that the cross-section views of coronary artery IMH appeared as a homogeneous, hyperechoic, crescent-shaped or circular area within media or between media or EEM, and the long axis views of IMH presented unbent or tortuous homogeneous space-occupying lesions with varied length.

结果：IVUS显示不冠状动脉壁内血肿的短轴观呈新月形或环形，呈等于或稍强于血液的斑点状回声，长轴观显示为中膜内或中膜与外膜之间长度不等的占位，形态或直或扭曲，呈接近血液回声或稍强回声。

The best way to describe understeer is to imagine you're going into a roundabout.

想象你正一个环形路段上开车就是对转向不足的最好描述。

The driver circuit of CCD is realized by CPLD (Complex Programmable Logic Device). In the multi-functions spectroscope's optical system, ring-shape aperture illuminates is used to reduce the sample's undersurface's reflection, then enhance the measurement precision of the reflectivity.

CCD的驱动时序电路通过可编程逻辑器件CPLD来实现，多功能光谱仪的光学系统中采用环形照明技术来减少玻璃样品下表面的反射，从而提高玻璃样品反射率的测量精度。

During ion source operating, alternating axial magnetic field and azimuthal electric field in discharge tube ionize hydrogen gas purified by hot palladium pipe, and form plasma. In fifties year, research reports studied on RF ion source are numerous however most of them are concerned about application, and research reports relevant to discharge theory or experiment model are unfrequent.

离子源工作时，放电空间交变的轴向磁场和涡漩电场激发放电管中经钯管纯化后通入的氢气电离，形成等离子体。50多年来，关于高频离子源的研究报告很多，但是，这些研究主要都集中在应用研究方面，有关高频无极环形放电离子源的理论与实验模型研究不是很多。

The area senior official's harbors the filled with anger just overtook " the star tyrant " the interspace fleet, saw only that Moon crater the peak crater, the sudden thick smoke billowing made a debut concurrently a dazzling glare, while the people hesitated surprised the moment, the following closely had the earthshaking large explosion, on Moon's this quiet hundred million year death volcano erupted once more, was bringing the innumerable robot body and the crag dark colored air column continuously flushes several ten thousand meters upper airs, Lian Heiqu senior official black Germany graceful driving flight vehicle 1, all had felt the fierce gas swayed with the instantaneous shock-wave.

黒区长官怀着满腔的怒火刚刚追上"星霸"的星际舰队，只见那座月球环形山的顶端火山口，突然浓烟滚滚并发出道道耀眼的强光，正当人们惊讶犹豫的片刻，紧接着就发生了惊天动地的大爆炸，月球的这座沉寂上亿年的死火山再次喷发了，带着无数机器人躯体和岩石碎块的暗黑色气柱一直冲到了几万米的高空，连黑区长官黑德曼驾驶的飞行器1号，都感到了剧烈气体摇晃和瞬间冲击波。

Seed vertical, brown, of same shape as utricle; embryo semi-annular; radicle inferior; perisperm scant.

垂直的种子，棕色，相同形状于胞果；胚半环形；胚根下位。外胚乳不够。

Objective:To evaluate the effects of two minimally invasive methods,percutaneous continuous circumsuture and transilluminated powered phlebectomy,in the treatment of primary vein varicosis of lower extremity.

目的：比较经皮连续环形缝扎术和透光刨吸术对单纯性下肢静脉曲张的治疗效果。

In order to do this, the width of narrow annuli cooling channel of beryllium beam pipe was designed by optimization method, the theoretical analysis and finite element method were used, then the optimal width was chosen, the influence of concentrated heat on the temperature of inner and outer wall was studied, and the optimal working velocity of cooling fluid was given.

本文结合理论分析和有限元数值模拟对束流铍管的冷却环形窄通道尺寸进行优化设计，确定了窄通道最佳间隙，研究了集中热负荷对内外壁温度场的影响，并确定了冷却液最佳工作流速。
