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。
