Methods On the basis of a great deal empirical and calculated data, a fundamental calculating formula was derived to calculate cosmic radiation dose rate in aerosphere from sea level to altitude of 25 km.

在大量实验和计算数据的基础上，推导出计算从海平面至25 km高度地球大气层中任意位置宇宙辐射剂量率的基本计算公式。

The key problem of the transmitted station is to find the suitable artificial seismic source: powerful, green and clear sources. With the development of airgun technique and information theory, it is possible now to obtain the image of a 100 000 km2 in spatial coverage and 40 km in depth by use of the transmitted seismic stations.

建立地震发射台的核心问题是选择合适的人工震源，近年来出现的绿色环保震源，以及现代信息处理技术的发展，使得建立照亮10万km2地区地下结构的地震发射台已经完全是可能的。

The airgun signal was detected all along the line of the largest offset equal to 185 km, seismic phases Pg, Pc, P2, PmP and Pn have been picked successfully, based on which 1-D forward modeling of deep crustal structure has been conducted and the low-velocity layer of crust-mantle transition zone has been discussed.

在185km长的测线上均记录到了气枪信号，成功检测到Pg，Pc，P2，PmP和Pn等多组震相，并在此基础上对地下深地壳结构进行了一维速度结构正演，讨论了该区域壳幔过渡带的低速结构。

This project also compared and discussed the research results of OBS and onshore-offshore experiments in nearby areas. The conclusion is that the active airgun source is equivalent to an earthquake of about magnitude 0.5, and the airgun signals can be detected at the maximum distance of only about 250 km, which is not enough for the study of deeper lithospheric structure below the crust. Furthermore, the onboard airgun source and MCS streamer are difficult to operate in the shallow water of reef and island areas.

本项目还分析对比了周边地区海底地震仪探测和海陆联合地震探测的研究成果，发现人工气枪震源约相当于0.5级的天然地震，其信号传播距离最远只有250 km左右，很难探测到地壳以下更深部的岩石圈结构特征，此外船载的气枪震源和多道电缆在岛礁区和浅水区很难开展工作。

A 4000+ km long "West to East Gas Pipeline" linking Shanghai and all the cities along the line to the gas fields in the Tarim basin.

一条逾4000公里长的"西气东输"天然气管道。这条管道连接了塔里木盆地与上海及其沿线各主要城市。

A total of 20.000 random donors of Chinese Han nationality living in Shanghai area were investigated for anti-bodies against IgG allotype by microhemagglutination inhibition test with panel sera of Gm, Km known type and 10 different special anti-D sensitized RBCs.

应用微量血凝抑制试验，Gm、Km谱血清和10种特异性抗D血清致敏红细胞，对上海地区2万名随机汉族献血者作IG同种异型抗体检测。

The lines of pine-trees whose width reached from 6 to 40 km stretched along many hundred kilometres through the Altai steppes.

松树的行树，其宽度从100多公里的沿拉伸通过阿勒泰草原的6至40公里到达。

It is computed with nearly 1.8 million terrestrial, ship, and altimetry gravity data, and is modeled on a 2' x 2' grid (about 3 km resolution).

这是近180万计算、船、altimetry重力数据，是仿照2×2的网格(约3公里处的分辨率)。

The Amazon in South America (6,400 km).

亚马逊在南美洲（ 6，400公里）。

"I will familiarize myself with the world of Formula 1, apprehend smooth. I will also have the opportunity to drive the Renault, Jerome d'Ambrosio listing site RTBF.be." So, next week I will participate in the shake-down at Silverstone where I will perform between 50 and 100 km before the cars are shipped to Bahrain .

雷诺第四车手会在R30运往巴林首站前在银石赛道进行测试(应该是FIA规定的直线测试)，应该会装上首站要用的全套件了，希望看到相关图片(又希望不要有图片流出导致其他车队看到)，内文中指的Next week，应该是指这星期吧，下星期车队跟装备都已经在巴林了

A carrier gas such as nitrogen is directed through line 20 and valve 22 to connect with line 26 and mix with the gas sample.

如氮气之类的载体通过管线20和阀22引入，与管线26相通，与气体样品混合。

But for the most part, knaves and parasites had the command of his fortune

然而支配他的家产的大多是恶棍和寄生虫。
