查询词典 normal atmosphere

For the first time we synthesized nanoscale metal hydrides of lanthanum, neodymium, samarium, dysprosium, and ytterbium with high efficiency under mild condition by complexometric catalysis instead of traditional preparation at high temperature and high pressure. It is for the first time that we synthesized lanthanide organic compounds with catalysts or initiating agents at atmosphere and ambient temperature,and some of them are new compounds. Nanometric lanthanide metal powders are prepared by thermal decomposition of the compounds in vacuum. Differently from the traditional method, size of the products prepared by our method is less than 40nm, and the activity of the reaction is very high. They are pyrophoric at atmosphere. They can make some reactions without activity or low activity show extremely high activity .We investigated influent regulations of methods, conditions to scale and special surface.

我们首次成功地用络合催化等方法取代需在高温高压下进行的传统方法，在温和条件下高效率地合成出纳米尺寸镧、钕、钐、镝、镱的金属氢化物；首次在常压常温的条件下，通过催化、引发等方法合成镧系金属有机化合物，再将其真空热分解成功地制备了纳米尺寸的镧、钕、钐、镝、镱等金属粉末；与传统方法不同，这些方法得到的产品基本颗粒尺寸小于 40 nm，遇到空气燃烧，具有极高的化学反应活性，使原来活性很低甚至观察不到活性的反应大幅度提高反应速率和产率；考察了制备方法、制备条件等因素对晶粒尺寸、比表面积大小等的影响规律。

Cao Guowei: The atmosphere that is brought up in one's childhood, actually I also am born in the Great Cultural Revolution, so we what doesn't the person that that time is born have actually too much the atmosphere that be in business, should for Shanghai whole environment is opposite China elsewhere for, I feel commercial breath or the commercial consciousness of people is stronger, this may have bit of effect, but I feel very much or the environment in grown the following very much education, job, can my whole business side the sort of no matter be recognizant it may not be a bad idea, experience it may not be a bad idea, can edify come out, be in especially sina I feel on this platform is very big to my help.

曹国伟：小时候长大的氛围，其实我也是在文化大革命出生的，所以我们那个年代出生的人其实并没有什么太多经商的氛围，应该来说上海整个环境相对中国其它地方来说，我觉得商业气息或者人们的商业意识是比较强的，这可能有点影响，但我觉得很多还是在长大以后的很多教育、工作的环境，能够把我整个的商业方面那种不管是意识也好、经验也好，能够熏陶出来，尤其在新浪这个平台上我觉得对我的帮助是非常大的。

The analysis of the mechanism of the effect of the surface type on atmosphere shows that the surface impact become gradually weakens. This indicates that stable atmosphere restrains the surface disturbance, and has the restorable ability.

通过对地表类型影响大气的机制分析，表明随着模拟时间的增加，地表的影响可能逐渐减弱，这显示出处于稳定状态的大气，可以抑制地表产生的这种扰动作用，表现出大气对地表类型改变产生扰动的一种自我恢复能力。

It was on the tip of his tongue to reply:"Don't be seen driving about the streets with Beaufort--" but he was being too deeply drawn into the atmosphere of the room, which was her atmosphere, and to give advice of that sort would have been like telling some one who was bargaining for attar-of-roses in Samarkand that one should always be provided with arctics for a New York winter.

他的想法都到了嗓子眼儿了，他想告诉说：&不要在人前和Beaufort一起游街。&可由于他太过沉浸于这个房间的气氛，感染于她带来的特有的氛围，提出这样的建议好比告诉在Samarkand购买玫瑰花油的人，如果在纽约，他得需要双防寒套鞋过冬。

The target and background physical model and infrared radiation are constructed and calculated separatedly based on Vega. Then the attenuate factor of atmosphere between scene and infrared sensor was calculated from atmosphere attenuate model. The infrared imaging system is simulated for generating the final infrared image.

针对低空红外预警的复杂场景，分别建立了目标和背景的辐射模型；考虑大气对红外辐射的衰减作用，建立了大气的传输模型；根据探测器的成像特性建立了成像系统响应模型。

The UMG polysilicon can be produced by heating the purified (NH4)2SiF6 above 500℃ in H2/Ar atmosphere. FTIR and XRD results show that amorphous polysilicon granules can be prepared after heat-treatment of (NH4)2SiF6 in a reducing atmosphere. The reduction of silicofluoride salts is a viable method for the production of UMG-Si.

将纯度较高的氟化矽铵盐在氢氩气氛中加热到500℃以上，可制造出冶金级的多晶矽，由XRD、SEM、FTIR与热分析之实验结果显示，在还原气氛中经热处理后所得之粉体为多晶矽，此种方法可以作为制造冶金矽的新方法，进而制备出太阳能产业级的多晶矽。

--- Water may be regained out of the atmosphere air by exposing hygroscopic substances to the atmosphere at night so that water is thereby absorbed, and subsequently subjecting the substance to the sun's rays during the daytime so that the absorbed water is evaporated into an air current which is cooled in order to liquify the water.

摘要---水可能会苏醒，脱离大气层空气中暴露吸湿物质到大气中在夜间，使水，从而吸收，并随后受到的实质内容，以太阳的射线在白天，以便吸收水蒸发成一目前的空气冷却，这是在以liquify水。

Even though the valuation of the atmosphere is hard,however,since the long-term of the climate changing,low discount rate should be applied to atmosphere resource.This generation should try their best to restore this kind of resource to make a concession to the following generations.
