In fact, the water flow intrudes upwards with a loss of the distance water and energy wastes for splitting rocks when confined groundwater intrudes upwards through coal seam water-resisting layer. The water flow under the coal seam scaleboard consumes more energy after it intrudes at a certain height.

研究结果在空间异质性孔隙介质有效参数的推估方法方面,显示利用传统抽水试验分析来估计有效参数时,从长时间的抽水试验分析所得的流通系数代表在抽水井有效半径内所有流通系数的某种平均值;此平均值与抽水井及观测井附近的地质有很大的关系,而且可能受到有效半径内地质异质性的影响,而储蓄系数的估计值变异很大与抽水井与观测井间地质的储蓄系数特性有关,特别是观测井的位置。

The study of vertical channel with high field effect mobility by Ni induced lateral crystallization, which can form larger grains on channel regions and reduce grain boundary defects. We detect the method of Ni induced lateral crystallization through high field effective mobility, but that accumulates too much Ni on floating N+ region and causes defects and metal contamination. As Ni is used to form silicde and then proceed to low temperature annealing, we can observe the floating region that has no Ni acumination regions or contaminations. This aids us in obtaining good electronic performance of this device, not only the remote field effective mobility but also the vast improvement of sub-threshold swing and on/off currents.
接著,是延续垂直通道的研究,希望能有效的提升电子迁移率,因此以镍金属诱导横向结晶的方式使通道形成较大的结晶,减少矽晶粒之间的缺陷,而在初步的研究,发现以镍金属直接诱导横向结晶的方式,经由低温长时间回火之后,由於镍金属扩散的关系,完成诱导结晶之后,有过多的镍金属聚集在顶部参杂的中间区域,而造成过多的缺陷累积,虽然电子迁移率有效的提升,但整体的电性并不如预期,因此提出先形成镍金属矽化物后,将未反应的镍金属或金属氧化物去除之后,再进行镍金属矽化物诱导横向结晶处理,经由结果观察得知在顶部掺杂区域部分没有明显的镍金属累积或污染,并且得到很好的整体电性,除了电子迁移率有效提升之外,次临界特性以及导通电流都能有效改善。

In 1966, Ross solved the equation of symmetrical free vibration and got six matching solution, but he believed that it is impossible to find a solution which is useful in everywhere. In 1979, Goldenveizer printed a monography in which the uniformly valid representations of curved solution were published, but the representations of membrane solution were still not found. In 1988, Ruo-jing Zhang published the uniformly valid representation of six solutions for symmetrical free vibration and eight solutions for dissymmetrical free vibration for the first time.

The effective information management must be closely related to effective user"s management, so effective user"s management becomes very important. But the development to effective user"s management system is very unstandard, Guide and standardize unifying , this must cause the reducing greatly of putting in an position of user"s management system , especially the use to user resources is very unfavorable, so a users management system in common use becomes of great significance.
而有效的信息管理必然与有效的用户管理密切相关,所以有效的用户管理就变得十分重要,但对于有效的用户管理系统的开发确很不规范,没有统一的指导和规范,这就必然导致用户管理系统的重用性的大大降低,特别是对于用户资源的利用非常不利,因此一个通用用户管理系统就变得意义重大。
