Taken together, our results indicated that zebrafish caspase-2 gene could be used as a model molecular to evaluate the effect of toxicants on apoptosis.

研究结果表明斑马鱼caspase-2基因是一个研究细胞凋亡行为的模型分子，可为环境化合物的分子毒性评价及其机制研究提供一种分子标记。

Germ warfare is an attractive terrorist option. After all, it is hard to prove or disprove what the terrorist claims to be able to do. Because germ agents are unseen, a tiny amount of agent has the potential to terrorize and disrupt the lives of millions. Imagine the terrorist who telephones a national newspaper to say that ten phials of nerve agents or hazardous viruses will be added to one of the thousands of distribution points of our domestic water supply. Over 30 million adults would be boiling all drinking water for weeks-especially if one or two had died already.

细菌战是对恐怖主义分子很有吸引力的一项，毕竟，难以证实或否定恐怖分子所宣称的，因为细菌战是看不到，措不着的，一点点剂量就对数百万人造成潜在威胁和打乱他们正常生活，试想一下：恐怖分子给国家主办的新闻报纸打电话，声称他们已经把数十瓶神经药剂和危险的病菌洒入了当地居民的水源供应地的数千个取水点，那么3000万成年居民数周内都要把水煮沸才敢饮用---尤其是有1-2人已死亡的情况下。

With the development of molecular-beam epitaxy and microfabrication techniques, people can arrange the atoms and moleculars at will and make various zero-dimensional, one-dimensional and two-dimensional systems even single molecular devices.

随着分子束外延等超薄生长技术和精细束加工技术的不断发展和完善，使人们能够按照自己的意愿排列原子、分子，制备出各种各样的零维、一维和二维纳米结构，甚至单分子器件。
