As water is lost from the surface of the leaves, a negative pressure, or tension, is created.
由于水从叶子表面丧失，一个负压力，或张力就得以产生。
The effect of dimethyl sulphoxide(DMSO)on micelle conformation of hexadecyltrimethylammonium bromide(CTAB)was studied by means of surface tension and negative staining TEM measurements.
通过表面张力法和负染色电镜法分别从两个方面研究了二甲基亚砜（ DMSO）对十六烷基三甲基溴化铵（ CTAB）胶束形成的影响。
