They said the International Ultraviolet Explorer satellite has shown them that T Pyxidis is really two stars, one called a white dwarf that is sucking in gas and steadily growing. When it reaches a critical mass it will blow itself to pieces.

他们说国际紫外线探测卫星显示，T Pyxidis实际上是两粒星，一粒被称为白矮星，它会吸啜气体和稳步增长，当到达一个临界量它会将自己炸到粉身碎骨。

Atomic bomb: In fission weapons, a mass of fissile material is rapidly assembled into a critical mass, in which a chain reaction begins and grows exponentially, releasing tremendous amounts of energy.

原子弹：裂变武器大规模的裂变材料正在迅速集结成一个临界质量，其中连锁成倍增长，并开始，数额巨大能量释放出来。

At this point the mass fraction of copolymer solution that is the critical mass fraction of the association.

此时共聚物溶液的质量分数即是临界缔合的质量分数。

A critical temperature of water is 100 degrees C--its boiling point at standard atmospheric pressure; critical mass; go critical .

This was just after the Critical Tits (a topless version of Critical Mass Bicycle ride)..

Caudatum was studied. 0.05 mg/L could be the critical mass concn. of P. caudatum fitting to Cu(superscript 2+).Below this concn., the polysaccharide content in P. caudatum was increased in a small range with the increment of mass concn. of Cu(superscript 2+),then the growth and propagation of P. caudatum was strengthened and above this concn., the polysaccharide content was decreased significantly with the increment of mass concn. of Cu(superscript 2+), then the growth and propagation of P. caudatum began to be restrained obviously and the poison was more obvious when the concn.

结果］0.05 mg/L可能是大草履虫适应Cu(上标 2+)的临界质量浓度，低于此浓度时，大草履虫体内的多糖含量随着Cu(上标 2+)质量浓度增大而呈现小幅度的增高，大草履虫的生长繁殖得到增强，高于此浓度时，大草履虫体内的多糖含量随着Cu(上标 2+)质量浓度增大而显著地降低，大草履虫生长繁殖开始明显受到抑制，且浓度越高受毒害越明显。

Theory predicts that a white dwarf star will explode when infalling matter from a companion star increases the mass of the white dwarf beyond a critical mass limit, known as the Chandrasekhar limit.

理论预言，当来自伴星的物质让白矮星的质量增加到了临界质量极限即钱德拉塞卡极限时，白矮星就会爆发。

Those ions will perform stable oscillation nearby the beam orbit while their mass is larger than a critical mass. The accumulation of trapped ions nearby the beam orbit, interacting with beam, can cause the tune shift of beam, blowup of beam emittance, increase of local vacuum pressure, and can even lead to the occurrence of beam instability.

这些被俘获的离子在束流轨道附近的积累并和束流的相互作用，会引起束流振荡频率的漂移和展宽、束流发射度的增加、局部真空度的恶化等各种负效应，有时甚至会导致束流不稳定的发生，从而影响储存环的正常工作，在这种情况下采用离子清洗方法将离子清洗掉对保证储存环的长期、稳定的运行是必要的。

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。"
