The determinations of the absolute magnitude and the kinematicparameters of RR Lyrae stars, their effects on the estimations of thedistances and the ages of the globular clusters, and the comparisonsbetween the results and ones from other indicators of distances arereviewed.

对天琴RR型变星绝对星等与运动学参数的测定及其对确定距离、球状星团年龄估计的影响，并对它们和其他距离指示器求得的结果的比较作了评述。

Forexample, the absolute magnitude of RR Lyrae stars determined from thedirect and indirect measurement methods splits into fainter and brightervalues, the distance modulus of Large Magellanic Cloud and theestimate of the ages of Globular Clusters based on the RR Lyrae starsand the other indicators of distances are not fully coincided.

例如由直接和间接测定方法决定的天琴RR型变星的绝对星等分成较暗和较亮两类，由天琴RR型变星和其他距离指示器决定的大麦哲伦云的距离模数和球状星团年龄估计并不完全一致。

SEM images show that the dolomite take the shape of the spheric aggregations with the diameter of 1~2μm, associated with the pyrite aggregations at the similar size.

对这些含白云石矿物的湖底沉积物所进行的扫描电镜研究发现了其中呈球状、椭球状，大小1~2μm的白云石集合体及其伴生的草莓状黄铁矿的存在。

The result shows that for both PCL homopolymers and PCL-b-PEG block copolymers, the spherulitic linear growth rate first increases with molecular weight and reaches a maximum, then decreases as molecular weight increases. Crystallization temperature has greater influence on the spherulitic growth rate of polymers with higher molecular weight.

当自由PEG在水中的占有面积S_o与单根PEG链段所占有的表面积S的比值S_o／S的值接近或小于3时，PEG链段对胶束形状的影响较小，PCL嵌段的影响占主导地位，易形成片状胶束；当S_o／S的值在3-10之间时，随着PCL嵌段分子量的增加，PCL-b-PEG嵌段共聚物在水溶液中自组装形成类似球状、棒状和蠕虫状胶束，是PEG与PCL嵌段共同的作用的结果；当S_o／S的值大于10时，易形成球状胶束。

The micelle shape transformation of tert-octylpheny phenol polyethylene glycol ether (TX-100), sodium dodecyl benzene sulfonate and tetradecyl trimethyl ammonium bromide in heavy water solutions was studied by 1H nuclear magnetic resonance spectroscopy, including an NMR self-diffusion experiment. These experiments showed that the surfactants formed several shapes of micelles (spherical, ellipsoidal, and rodlike) at the respective concentrations which were far above their critical micelle concentration.

运用核磁共振一维氢谱和自扩散实验方法研究了聚乙烯乙二醇异辛酚醚(TX-100)、十二烷基苯磺酸钠和十四烷基三甲基溴化铵三种不同类型的表面活性剂在重水溶液中的胶束形状转变，发现它们在临界胶束浓度以上的各自相应浓度都有胶束形状的变化（由球状转变为椭球状或棒状）。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
