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。

You probably wouldn't want to run across the venomous Gumprecht's green pit viper, like the adult male seen here--the species can grow up to 4.3 feet (1.3 meters) long.

你大概不愿意在一条剧毒的Gumprecht绿斑蛇上面走过，就如图中所见的这条成年雄蛇，这种物种能够长到约4英尺（1.3米）长。

Cyanide: Any of various salts or esters of hydrogen cyanide containing a CN group, especially the extremely poisonous compounds potassium cyanide and sodium cyanide.

氰化物：一种包含CN基团的氰化氢的盐或酯，特别是剧毒化合物氰化钾和氰化钠。

A new technique of imitating gold plating by substituting pyrophosphate for toxic ayanide was reported.

报导了一种用焦磷酸盐代替剧毒氰化物的仿金电镀新工艺。

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."

我在这里例举胡家奇所引用过的例子："据报道，美国利用转基因技术，将一种病毒的DNA分离出来，与另外一种DNA进行结合，拼结成一种剧毒的"热毒素"生物战剂，且私下有人透露，这种生物战剂只需20克，就可以导致全球60亿人全部感染死亡。"

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.
