The earth is a complicated system, and it has been continuously moving differentiating and evolving since it had been formed. Not only has the earth layering structure, but it has vertical movement of materials. The movement is prompted by the mechanism of force and heat of the centrifugal force to be formed by the rotation and revolution of the earth, and difference of temperature, pressure, density, viscosity and velocity in the between core and mantle, and radioactive heat, et al. The expressive means of the mechanism of force and heat are the precesses of mantle plume and mantle fluid. Not only are ore-materials of core and mantle carried directly into crust, but ore-materials of crust are activated and accumulated into proper location by the mantle fluid having the supercritical nature.

地球是一个复杂的系统，自形成以来，一直处于不停地运动、分异和演化过程；它不仅存在着圈层结构，而且伴随其自转和公转的离心力，以及核幔间的温度差、压力差、密度差、粘度差、速度差和放射性蜕变热等动热机制，同时存在着以地幔柱和地幔流体作用方式的物质垂向运动；这一过程，不仅直接向地壳带入核幔成矿物质，而且通过流体自身的超临界性质，将沿途活化已有初步富集的成矿物质转移至地壳适宜部位集中成矿。

On the other hand, as the pollution-carry capacity of the atmosphere is being exhausted, a globally effective ban on ozone depleting substances appears warranted to avoid globally distributed environmental,public health or ecnomic detriments due to increased UV-B raditation.

另一方面，大气污染的运输能力正在被耗尽，全球的对于消耗臭氧层的物质的使用的有效控制显得更为重要，它可以有效地解决由于放射性元素 UV-B 增加带来的全球性环境、公共健康和经济毁损问题。

DR. DAVID DINGES: Space itself is extremely demanding, they work incredibly hard, the risks to them are considerable from radiation and the hostile environment, they also experience the very tight confines of the small spacecraft.

大卫·丁格：太空本身就是个要求苛刻的地方，所以他们的工作难以置信的辛苦。他们所面临的危险是很多的，从放射性到相悖环境，而且他们也必须严严实实的封闭在狭小的太空舱内。

Zhangtianqu oilfield locates in the center of Yixia west slope, Ordos Basin. The field has a complex hydrocarbon-bearing bed set. On principle that lithology and reservoir can be identified, geologic parameters such as shale content, porosity, and oil saturation can be determined and be used to distinguish oil-bearing formation from water formation, as well as costeffectiveness, an improved logging interpretation model has been established. The model extends conventional single porosity interpretation methodology to identify various lithologies (such as coal seam, radioactive sandstone, carbonate rock besides sandstone and shale) by comprehensively analyzing the logging responses of sand reservoirs on economic logging set of acoustic logs and induction logs. Applications on real data show the improved model is superior in identifying complex lithology with conventional logging data.
