Furthermore, the experiences of artificial breeding and farming showed that different geographical populations of Meretrix clam are also substantially different in growth rate and the ratio of shell weight to soft-body one.

由于我国海岸线漫长、地形复杂，因长期地理隔离和生境不同，导致不同海域的文蛤在壳表形态和颜色、花纹图案等外观特征上均存在显著差异；另外，从多年的养殖实践中也发现，我国文蛤不同地理群体在生长速度、壳肉重比率等重要经济性状上也存在着显著差异，而这些性状的稳定性差异必然依赖于其分子遗传结构的变异。

A special field equation with of Faddeev model is solved. The analytical solutions with time variable of Faddeev model are obtained by utilizing the result that the SO (3) Faddeev model is equivalent to the mesonic sector of SU (2) Skyrme model where baryon number current vanishes everywhere.

The peak metamorphic minerals are garnet, omphacite,phengite and rutile with temperature of～500℃,pressure of～2.3Gpa.On the basis of geochemical analysis,the content of SiO2 in the eclogite ranges from 46.68%to 50.24%,Na2O+K2O 3.10～4.21%,and high REE with enriched LREE, LREE/HREE of 2.83～6.06.The REE pattern and trace element spidergram are similar with those of ocean island basalt,according with the blueschist from Longmucuo -Shuanghu suture zone.The protolith of the eclogite and blueschist are OIB,and they aremaybe the result of subduction of Permian OIB in central Qiangtang area.

对棉辉岩的地球化学分析显示，榴辉岩SiO_2含量在46.68—50.24%之间，Na_2O+K_2O含量在3.10—4.21%之间，稀土元素总量较高，轻稀土富集，重稀土相对亏损，LREE/HREE比值在2.83—6.06之间，稀土元素球粒陨石标准化曲线呈向右倾斜的样式，微量元素原始地幔标准化蛛网图OIB类似，这些特征和龙木错—双湖高压变质带的蓝片岩类似，它们的原岩为均为洋岛型玄武岩，形成环境类似于现在太平洋中的夏威夷，榴辉岩、蓝片岩很可能是羌塘中部地区出露的二叠纪洋岛型岩石俯冲消减的产物。
