Thirty cases (60 sides) of the hippocampus cortex in the cerebrum of human fresh copses from fetus (6 months) to children (old 6 years) were stained by AKP , and then observed and taken enlarged pictures were taken under microscope. All epillaries on these photoes were measured by vernier caliper and "ratio of volume" of the capillary were calculated by new method.

采用 30 例(60 侧)6 个月胎儿至 6 岁儿童新鲜尸体大脑，用碱性磷酸酶染色，在光镜下观察毛细血管分布，显微放大照相，自动彩扩机扩印照片，游标卡尺测量并计算海马皮质毛细血管&比容积&。

On the basis of summarizing separation method of acetic acid-water system, we studied the azeotropic distillation process of acetic acid-water system, selecting butyl acetate, isobutyl acetate and isopropyl acetate as entrainers. The influence of packing height, ratio of water to entrainer and acetic acid initial concentration to separation effect of azeotropic distillation was studied in detail. Simulation calculations of general distillation and azeotropic distillation were carried out. The influence of reflux ratio, theoretical plate, feed position, feed temperature and feed concentration to distillation process were discussed. Preferred process operation parameter, which had guiding meaning to practical production of distillation process were obtained. Basic data for the process amplifying design of azeotropic distillation tower were provided. Invest and operation energy consumption of two distillation methods were compared. The elementary technical design of azeotropic distillation tower was carried out on the basis of result of simulation calculation. The type of major auxiliary equipments and inner parts of packed tower were selected.The research results are as follows:(1) Butyl acetate, isobutyl acetate and isopropyl acetate could be selected as entrainer, and separation effect was near.

本文在综述醋酸-水体系分离方法的基础上，以醋酸丁酯、醋酸异丁酯、醋酸异丙酯为挟带剂，对醋酸水溶液进行共沸精馏过程研究，详细研究了填料高度、水与挟带剂的配比、醋酸初始浓度等对共沸精馏分离效果的影响；对醋酸-水体系进行普通精馏和共沸精馏过程模拟计算，讨论了回流比、理论板、进料位置、进料温度和浓度对精馏过程的影响，获得了对醋酸-水体系精馏过程实际生产具有指导意义的较佳的工艺操作参数、共沸精馏塔的工艺设计放大的基础数据，并对两种精馏方法的投资、操作能耗进行了比较；同时在共沸精馏模拟计算的基础上进行了共沸精馏塔的初步工艺设计计算，并对填料塔的主要辅助设备及塔内件进行了初步选型。

The wave propagation and refraction of type "O" irregularities in the counter-electrojet conditions is investigated with a model electrojet in terms of the linear theory of the electrojet instability.

本文分析了反向赤道电射流条件下的不均匀性的对流放大特性。根据电射流不稳定性的线性理论，对一个分层均匀的电射流的模式的数值计算表明：在反向电射流条件下，电射流不均匀性有如下的特性：在波的传播过程中，在上电射流区内，波矢向下旋转，在下电射流区内，波矢向上旋转；在驱动电场E_D数值相同的情况下，反向电射流条件下的射线路径积分增长率r比正常电射流情况的要小得多。

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。
