氢气的

UGC 5101 is a peculiar galaxy with a single nucleus contained within an unstructured main body that suggests a recent interaction and merger. UGC 5101 is thought to contain an active galactic nucleus an extremely bright, compact core - buried deep in the gas and dust.

ugc5101是一个仅有单独一个星核的特殊星系，并且没有结构性的主体，这一切都说明他是最近才发生接触并碰撞的。ugc4101被认为包含一个活跃的星系核，其非常明亮，非藏紧密—在其深处埋藏着氢气核尘埃。

Our corrugated arrestor with anti-exsplosion with some state of ants in British , Germany , Nloing with better manufacturing and inspection equipment,have good features , such as compact structure ,good reliability especial for H2、 O2、 LPG and so on.

我公司综合引进英国、德国等公司的先进技术，配之先进的加工设备和完善的检测装置，生产的防爆波纹阻火器，具有结构紧凑，可靠性高，阻火芯件防爆、防腐、阻火性能强、便于清洗等优点，特别适合于氢气、氧气、液化气等特殊介质。

The vivid green and purple auroral colors are caused by high atmospheric oxygen and hydrogen reacting to a burst of incoming electrons .

那鲜艳的绿色和紫色是由飞速而来的带电粒子轰击着高层大气中的氧气和氢气而生成的。

Now Angela Belcher of the Massachusetts Institute of Technology and her colleagues have succeeded in mimicking the first part of photosynthesis by using a genetically modified virus to help split water into hydrogen and oxygen.

现在麻省理工学院的安吉拉。贝尔切和她的同事们成功模拟出了光合作用的第一部分，他们使用一种基因改良的病毒来促进水分解为氢气和氧气。

While hydrogen obtained from water is the gas that would be used as a fuel, the splitting of oxygen from water is the more technically challenging "half-reaction" in the process, Belcher explains, so her team focused on this part.

这种方法使产生氧气的效率提高了4倍，研究人员希望能够找到同样的以生物学为基础的系统来完成这个反应的另一半过程——分离氢气。目前，从水中分离的氢被分成质子和电子。

These dust and gas clouds lie near the edge of a large molecular cloud. Themselves telltale signs of star-forming regions, they tend to hide the newly formed stars and young stellar objects or protostars from prying optical telescopes.

这些尘埃与氢气云都位在一个大分子云的边缘，而它们本身也是恒星诞生区的标志，不过对光学望远镜观测来说，它们也是遮掩新生恒星和原恒星的障碍。

When the fuel ratio is high, thermal choke occurs in the combustor. Then it will be eas y to hold the flame, the distribution zone of which exˉ pands due to the improved penetrability of kerosene, and consequent ly the drag caused by the strut and ramp decreases.

诱导氢气与煤油共同燃烧时，燃烧室内发生了热力壅塞，此时煤油的穿透度大幅度提高，火焰分布范围更广，稳定火焰的难度降低，支板与斜坡所引起的阻力也随之减小。

At certain temperature and hydrogen flow rate, the weight changing of tungsten trioxide during the reduction was investigated by thermo balance, and the phase transformation analyzed by means of XRD.

在一定的温度和氢气流量条件下，用热分析天平精确测量WO3 还原反应过程中，不同时间的质量变化，并用X射线衍射分析进行物相鉴定，绘制纳米级WO3 (粒径≤ 5 0nm)的还原动力学曲线。

When alloy is redeposited, the places where hydrogen was adsorbed begin to preferentially nucleate and grow. It cut off the ways that needle holes form.

再次沉积时，在原氢气泡吸附的位置，成为优先形核与长大的地方，有利于切断针孔形成的途径。

The new approach devised by the Weizmann team has three important steps that end in liberation of hydrogen and oxygen with the help of a special metal complex.

新的方法设计的魏茨曼队有三个重要步骤，目的解放氢气和氧气的帮助下，一个特殊金属络合物。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
