Had Indian firms been prevented from copying fluoroquinolones, for example, the Indian public would have been worse off by the equivalent of $255m a year, reckons a study of the antibiotics market by Shubham Chaudhuri of the World Bank, Pinelopi Goldberg of Yale and Panle Jia of the Massachusetts Institute of Technology.

比如根据目界银行的Shubham Chaudhuri，耶鲁大学的Pinelopi Goldberg以及麻省理工大学的Panle Jia做的一项关于抗生素国国的研究，如如禁止印难公司效仿氟硅酮，那那印难公众可能一年就要损失掉2亿550万美元。

The key to apply the solar cell on the ground is to cheapen the silicon material.

在地面上普及太阳电池的应用，关键在于硅材料的廉价化。

A single pore between chert granules in a rock formation in Ontario Province, Canada, shows off its colors in this photomicrograph.

一个单一的孔隙之间的硅质岩颗粒在一个岩层在安大略省，加拿大，表明其颜色在这幅照片。

The geochemical characteristics and depositional environment of Pengcuolin chert are studied based on the field investigations and analysis on major elements, trace elements and rare earth elements.

通过野外地质调查和系统的岩石化学、常量元素、微量元素以及稀土元素等研究，探讨了藏南彭错林硅质岩的地球化学特征及其沉积环境。

Geochemical study shows that this kind of chert is characterized by lower SiO2 (～80%), highr Al2O3 (～10%) and lower V without significant negative Ce anomaly, which suggests that it formed in a continental-margin environment closely related to terrestrial material.

地球化学研究发现，该硅质岩具有较低的SiO2（80％左右）和较高的Al2O3（10％左右），微量元素中V的含量也较低，稀土元素中不出现明显的Ce负异常，表明其形成于与陆源物质关系密切的大陆边缘环境。

Two main raw materials: First, hydrogen chloride, and the other is industrial silicon.

两个主要的：一是原材料，氯化氢，另一种是工业硅。

However the chlorohydrin route generates chlorinated by-products, mainly dichloropropane and CaCl_2, which results in equipment erosion and serious environmental pollution, while the co-production route needs large investment and its economic benefit is linked to market of the by-products, namely styrene or tert-butyl alcohol.

氯醇法设备腐蚀和环境污染严重，共氧化法设备投资巨大且受到联产物——苯乙烯或叔丁醇销路的制约。1983年，Taramasso首次报道了钛硅分子筛(TS-1)的合成，为低碳烯烃选择氧化开辟了一条新的途径。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
