| 摘 要： | 观察研究了偏心海链藻壳面形态的变异及变异的原因。结果表明，壳面形态变异是偏心海链藻的典型特征，依变异程度不同可分为４种类型；硅含量对其壳面形态影响显著，但硅质不足是形态变异的唯一原因。

| Abstract: | In our experiment, the valve morphological variation of Thalassiosira eccentrica was observed and its origination was studied. Results showed that valve morphological varistion, which is divided into 4 types according to variation degrees, is typical feature of T. eccentrica. Silicate content has remarked effect on the valve pattern, but silicate limitation is not the sole factor. |
