The sinking rate of the spherical heavy solid in static liquid is in accord with Stocks formula.The plutonic inclusions in igneous rocks which formed as a result of solidification of magma have the same relation as magma.

静态流体中的球形固体重物的沉降速度服从Stocks公式,岩浆岩是由岩浆上升冷凝而成,在形成时与其中的深源包体也是这种关系,只是包体没有沉下去,反而随岩浆上升,说明岩浆上升速度大于最重最大包体的下沉速度,据此可确定该岩浆岩形成时岩浆流体上升的最小速度并推导出计算公式。

Because the above surface breaks the point symmetry of spherical dome, the system may introduce dynamical aberrations depending on Regard of View and Field of View, which is characterized by large tilt and large eccentricity.

但是上述表面破坏了球形整流罩的点对称几何特性,使该系统具有大倾斜、大偏心光学特性,引入依赖于目标视场和瞬时视场的动态像差特性。

The basic idea of single curvature polyhedron high temperature bulging technology for manufacturing spherical tanks is put forward.

提出了单曲率多面壳体高温胀形制造球形容器工艺的基本思想。

The dissolubility of PPLA in water was (2.16~4.32)×10-2 mg·mL-1 according to eye judgment. The critical micelle concentration was 2.16×10-2 mg·mL-1 obtained from a fluorospectrophotometer. The self-assembled aggregates of PPLA in water were nanoscale spheres observed by a transmission electron microscope. The particle size and zeta potential tests by dynamic light scattering revealed that during preparation, the ratio of hydrophilicity/hydrophobicity, the aqueous medium and the pH had great influences; while dilution, freezing and pH change to basic condition had no effect after preparation, but pH change to acidic condition made the nanoparticles precipitate.

目测法得到其溶解度为(2.16~4.32)×10-2 mg·mL-1;荧光法得到聚合物的临界胶束浓度为1.12×10-3 mg·mL-1;透射电子显微镜观察显示该聚合物在水中的自组装聚集体为纳米级球形;动态激光光散射测试微球的粒径和Zeta电位发现,在微球的制备过程中,聚合物的亲/疏水性比例、水相介质及水溶液的pH值对它影响显著;而制备后,稀释和冷冻对它无显著影响,改变微球的环境pH值至酸性,出现聚集,至碱性无影响。
