等变晶的

The composition, crystal modification and microstructure of Na〓SO〓/SiO〓 CESM are researched by using metallography microscope, X-ray diffractometry, scanning electron microscope and energy dispersive spectroscopy. The results show no new substance appears other than quartz and thenardite, but the crystal modification phenomenon is discovered; quartz and thenardite are combined very well with wetting and mechanical inserting; a dense and continuous microstructure is seen in fractography, but holes and cracks defects are found too.

研究结果表明最终制备出的复合相变储能材料在常温下的主要物相为α—石英和芒硝〓—T，与制备前相同；制备工艺对复合材料的最终的物相变化影响不大，仅仅是制备过程中出现各组份的晶型转变；复合储能材料物相分布较为均匀，预制体粘结良好，两相基本互相包覆，其间仅是因浸润结合而形成的机械嵌合作用；复合储能材料中存在有封闭孔、杂质、未渗区等各种缺陷。

Capillary phenomena was studied and discussed by the scholars about 200 years ago, but the progress was slow due to the limited equipments and manufacture precision of the microchannel.In recent years, because of the rapid development of MEMS and micromachining, many applications of the capillary flow is widely developing in some modern processes, such as underfilling of flip chip, flow in microfluidic chip or biochip, and a variety of other fields.

摘要 毛细现象大约在200年前便断断续续被欧美学者所研究讨论，但由於当时微细加工受到仪器设备和制造精度的限制，因此发展极为缓慢；近年来由於微机电系统与微细加工之精进，许多具有微流道的应用设备，陆续被制作问世，加上光学显微镜与影像撷取设备的普遍，对於研究此课题的推展极有助益；且随著微生医、覆晶底胶充填与微流体系统等领域之受到重视，毛细现象导致的充填问题、驱动原理及液体流动的控制，都变得相当的重要；本研究基於如此的动机与目的，进行微流道内液体之毛细流动现象及时间的探讨。

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。
