Scientists have found many planets like HD 209458 b huge gas giants that orbit hazardously close to their stars and have hellishly hot, poisonous atmospheres.

科学家们已经发现了许多类似HD209458b的行星-拥有庞大的大气层，却离它们的恒星很近的运行，可怕的炎热，剧毒的大气。

MMA is produced by the method of acetone-cyanhydrin mainly in our country. The synthetic route is complex, the technical line is long, and the yield is low with high cost after many steps. Hydrocyanic acid is used as raw material, the treatment of numerous waste acid is difficult . Furthermore, concentrated sulfuric acid consumed in this method corrodes equipments and pollutes the environment seriously.

我国MMA的生产以丙酮腈醇法占主导地位，合成路线复杂，生产工艺长，多步反应后产率低，成本高，其采用有剧毒的氢氰酸为原料，产生大量难于处理的废酸，所消耗的浓硫酸对设备腐蚀性大，对环境污染严重，因此开发新的MMA工艺路线很有必要。

A series of convenient and efficient reactions have been developed. Especially, instead of using toxic phosgene, the triphosgene was employed in the synthetic process of some receptors, which provides a convenient. safe and efficient method for the preparation of chiral unsymmetrical urea.

深入研究了它们的合成方法，实现了多种简便有效的选择性合成，特别是以三光气代替剧毒的光气，实现了一条简便、安全、有效的制备手性不对称脲的方法。

The construction projects which may induce serious secondary disasters mentioned in this Law refer to construction projects which may, as a result of earthquake damage, lead to flood, fire, explosion, leak of a large amount of hypertoxic or strong corrosive materials and other serious secondary disasters, including such projects as large dams, embankments, petroleum and gas tanks and the facilities storing inflammables or explosive substances, hypertoxic or strong corrosive materials and other construction projects which may induce serious secondary disasters.

本法所称可能发生严重次生灾害的建设工程，是指受地震破坏后可能引发水灾、火灾、爆炸、剧毒或者强腐蚀性物质大量泄漏和其他严重次生灾害的建设工程，包括水库大坝、堤防和贮油、贮气、贮存易燃易爆、剧毒或者强腐蚀性物质的设施以及其他可能发生严重次生灾害的建设工程。

43 Any production activities (including weighing, milling, or packaging) of highly toxic nonpharmaceutical materials, such as herbicides and pesticides, should not be conducted using the buildings and/or equipment being used for the production of APIs.

4.43 剧毒的非药用物质，如除草剂，杀虫剂的任何生产活动都不应当使用生产原料药所使用的厂房和/或设备。

There is a great price to pay though, for the poison numbs the senses so that the riders can no longer taste food or feel a touch.

这样作需要付出极大的代价，因为剧毒的副作用麻痹了他们的感觉器官，骑士们再也无法品尝到食物的味道，无法再拥有肉体接触的感觉。

Or fer-de-lance, family, are common throughout their range and areresponsible for a large number of snakebites in Brazil, Paraguay, andArgentina.

这种剧毒的蝰蛇是矛头蛇的一种，在其分布地区十分常见，并在巴西，巴拉圭和阿根廷等地造成了大量的毒蛇咬伤事故。
