球形的

In addition to the sun, other stars may also have their own planets, broadly speaking, any movement around the star, the quality does not meet the thermonuclear reaction can produce the quality of the main sequence stars the approximate lower limit of spherical objects can be called planets .

除太阳外，其他恒星也可能有自己的行星，广义上说，凡是环绕恒星运动的，质量未达到能产生热核反应的主序星质量下限的近似球形的天体都可称为行星。

In this thesis the solid-state reaction at room temperature was applied to prepare nanometer barium carbonate. The feasibility of this method was studied and an optimized procedure for the preparation of nanometer barium carbonate was set up.

本文采用室温固相化学反应的方法，研究了在该条件下制备纳米BaCO_3的可行性，建立了制备纳米BaCO_3的方法体系，制备了平均粒经约为100nm，形貌近似为球形的纳米BaCO_3。

The measurements of self-diffusion coefficient,spin-spin relaxation and interproton distance at 318 K suggest that N,N′-bis-α,ω- alkane propane diammonium dibromide (16-3-16) quasi-global micelles are formed in the dilute solution at a concentration of 0.26 mmol/L and the head groups are in a saw-toothed form staying at the surface of the micelle to overcome the strong electrostatic repulsion force.

从自扩散系数、横向弛豫和质子距离等NMR测定参数推测，在浓度为0.26 mmol/L（318 K）的N，N′-双-α，ω-丙烷溴化铵(16-3-16)溶液中形成了近似球形的胶束，胶束表面的带正电荷的铵基极性头呈锯齿状排列以减弱分子间静电排斥力的影响。
