I also find that the aggregation is rapidly re-suspended by an ac electro-osmotic flow, due possibly to Faradaic charging, at large voltage like 50 Vpp.

另外加高操作电压至50Vpp而频率为1MHz时，会发现聚集粒子被交流电渗流迅速地带走，此现象有可能是电化学反应所导致。

In addition, this paper studied using the stochastic fractural theory to simulte the form of fracture, and thought that it is correct to describe fracture by the fractural characteristics of fracture grid.

The results of this study showed that the influencing factors of slope instability for the Luchang Area include rock fall at the west slopes, thick colluvium, sliding planes for dip-direction slopes, headward and sideward erosion of channel, as well as fast seepage of ground water. Two slide planes were recognized from geological profile model. One is potential slide plane on the dip-directional slope, another plane is located in the colluvium near Luchang river sides.

本研究结果显示，鹿场地区地质环境之不安定原因，有西侧岩壁落石、厚崩积土体、顺向坡平面滑动、河道的向源侵蚀和侧蚀、地下水渗流快速等；就所建构地质模型可以了解，鹿场地区可能的滑动面有两部份，一为潜在的顺向坡平面滑动面，另一为在鹿场溪河岸崩积层边坡内的滑动面。

On the base of the brief description of the drive and control system of micro-fluid and the experimental setting of the technology of micro-injection, a novel process of the hydrophobe treating used to mend the characteristic of the inner and outer surface on micro-pipette is designed, which can improve greatly the injected effect and eliminate the disadvantage such as seepage or regurgitation during injection. The author puts forward the way of measuring the inside diameter of the micropipette. The program of measuring micro injection amount is designed. The original data of the micro injection experiment are explained and interpreted at last in the thesis.
