There are series of papers studying the solvability of an incompressible, viscous, instationary fluid contained in a domian bounded entirely by a free surface. In 1977, Solonnikov proved its local solvability in a Holder space for any initial date but without surface tension. In 1984, he considered the same problem in a Sobolev space with surface tension being taken into account. In I992, Mogilevskii and Solonnikov treated the same problem in a Holder space, where the coefficient of surface tension is not a constant. There are also short-time existence results for the solvability of an incompressible, vicous, unsteady fluid bounded above by a free surface and below by a fixed bottom which approach horizontal planes at infinity. In 1981, Beale proved its local solvability in a Sobolev space for any initial date but without surface tension. In 1983, Allain were concerned with the same problem in R〓 with surface tension but under the assumption that the initial fluid domain was near a horizontal strip. In 1987, he obtained the same result without the preceding assumption. In 1996, Tani solved the same problem in R with surface tension. For the solvability of an incompressible viscous instationary fluid in Ω R bounded inside by a free surface S and outside by a rotating boundary S, in 1995 Ciuperca proved its local existence in a Sobolev space for any initial date but without surface tension. In this paper, we consider the same problem with surface tension.

对于边界完全是由自由边界组成的有界区域中粘性不可压流体的非定常运动问题，Solonnikcv于1977年在忽略表面张力情况下证明了初值问题小时间解在Holder空间的存在性，于1984年在有表面张力情况下证明了初值问题问题小时间解在Sobolev空间的存在性，Mogilevskii和Solonnikov于1992年在表面张力系数可以不是常数情况下证明了初值问题小时间解在Holder空间的存在性；对于上面是自由边界、下面是固定边界且两边界在无限处趋于水平的无限区域中粘性不可压流体的非定常运动问题，Beale于1981年在忽略表面张力情况下证明了初值问题小时间解在Sobolev空间的存在性，Allain于1983年在有表面张力情况下证明了R中初值问题小时间解在Sobolev空间的存在性，但其中假定初始区域近似是个水平条，他于1987年去掉了这个假定得到同样的结果，Tani于1996年在有表面张力情况下证明了R中初值问题小时间解在Sobolev空间的存在性；对于R中内面是自由边界、外面是旋转边界S的有界区域中粘性不可压流体的非定常运动问题，Ciuperca于1995年在忽略表面张力情况下证明了初值问题小时间解在Sobolev空间的存在性，本文考虑了在有表面张力情况下初值问题可解性问题。

应用 PIV 分别研究了不同浓度的聚合物溶液以及牛顿流体在垂直环空管道中的流动规律，得到了环空管道中流体的速度分布情况、涡量情况、流线情况，分析了同心和偏心情况下环空管道内的流场分布规律，并与前人的计算结果进行了比较，得出了一些与以前不同的结论：同心情况下平均流速与最大流速的关系，并不是完全与粘性指数 n 值有关系，还与管道内流动的流动速度有关系，当速度较小时，两者的差别就小，速度大时，不符合这种规律。

The activated or leached process and their influence elements are studied by 1DREACT software package of coupled mass/heat transfer and chemical reaction dynamics of water-rock interaction, according to the geological and geochemical characters of fine disseminated gold deposits.(1) Water-rock reaction time is not the important influence element of activating gold;(2) At first, activating capability of hydrothermal solution increases with the increasing of total sulfur activity; after lga〓≥-4, the content of activated gold in solution is mainly related to original content of gold in wall rock, and does not visibly dependent on total sulfur activity.(3) It is a complicated nonlinear process of influence of activating gold capacity of hydrothermal solution with the change of temperature, in general, 220 ℃ is most favorable to gold activation.(4) The influence of oxygen fugacity on gold activation has a multiple functions coupling nonlinear effect, in general, Igfo〓=-41 is most favorable to gold activation.(5) Solubility of gold in fluid decreases with the increasing of velocity of flow, the product of velocity and aurous solubility reaches maximum when velocity is 0.2～0.5m〓m〓. yr〓, i. e. this scope of velocity is most favorable to gold activation.

In view of inhomogeneous distribution of fluid pressure, fault-valve behavior and the coupled equations of the current density and fluid flow within the Earth's crust, especially, the observed anomalies in electrical field showed a similar pattern of rapid starting and slow decay, some of these anomalies associated with episodical spouting from borehole or the increase of fluid pressure in wells, it is reasonable to consider that the source of precursory electrical field anomalies is the streaming potential mechanism.

鉴於地下流体压力分佈不均匀、断层阀作用及地下电流密度与流体流的耦合方程，特别是由於电场异常显示出快急始慢衰减的特殊图型，电场异常有的与废油井间歇自喷有关，有的与流体压力增高有关，故认为过滤电势作为电场前兆机制是合理的。

The variables in controlling the flow of microfluids are voltage and time. This study adopted the method of fast measurements、so time taken for applying voltage did not exceed ten minutes. If voltage is not carefully controlled、the microchannel may be damaged at the particle flow. During measurement、a buffer fluid with a concentration of 0.1 M was used、the current was sufficient to propel the magnetic particles through the microchannel without damage from excessive voltage. The maximal amount of microfluid particles at the junction of the separation and injection channels was obtained with a time of 5 mintures and voltage of 200V.

藉由改变不同的电压和时间来观察颗粒在微流体中的移动情形，由於这个研究是以快速检测为原则，所以将时间控制在10分钟之内；在电压的控制上面如果电压太大的话将会对微流体的管道造成损伤，降低微流体装置的寿命，并且也有可能会对里面的颗粒造成影响，所以缓冲液的浓度使用比较大的0.1 M，这样所产生的电流将足以推动磁性颗粒并且电压不会太大也不会造成管壁的伤害。

Apart from the working limitations resulting from its structural property, the flat plate heat pipe carries out heat dissipation through the evaporation and condensation of the working fluid. Thus, if the working angle of the fluid is adverse to its backflow, the heat pipe will fail easily. Furthermore, not the orientations of all the heat sources are favorable to the functioning of the heat pipe. To compensate for this drawback, this research focuses primarily on the development of a composite structure which will reduce the effect of gravity on the working fluid. Generally speaking, the heat pipe is divided into three main categories: the groove type, sintered metal type and mesh screen type, as shown in Table 2. As far as capillary force is concerned, the sintered metal type and mesh screen type show better performance. As mentioned in R.

平板式热管除了因其结构特性而产生的工作极限之外，由于其作用乃是透过工作流体的蒸发及凝结进行散热，故若是其工作角度不利于液体之回流，便容易使热管失效，且并非所有之发热源都是位于有利于热管工作之位置，因此本研究之主要目的为设计一可减少重力对工作流体影响之复合式结构；一般而言，热管之结构大致可分为沟槽、烧结及网格三种(如表2所示)，其中烧结及网格结构有较佳之毛细力，在 R。
