In conclusion, the lag phase of Streptococcus thermophilus was shorten in the eutrophy culture medium, and the time achieving the culminated point of logarithmic phase was shorted also, at the same time, the stationary phase lengthened. After secondary culture, Streptococcus thermophilus reached directly the log phase hardly through the lag phase, and then quickly reached the decline phase. There were more relations of the metabolic regalities of the three kinds of nutritive substances with the super-concentrated incubation process of Streptococcus thermophilus: the more the number of the bacteria, the quicker the metaboling, while the fewer, the slower the metabolism. Moreover, there apparently existed morphologic changes in this course, and there maybe existed the apoptosis, which correlated with bacteria propagation and acid producing. With the culture time postponed, the nutritive substances in the culture medium lacked also, and the morphologic change and apoptosis appeared more obviously.

结果表明，嗜热链球菌在营养丰富的培养基中的生长延滞期缩短，到达对数生长顶点的时间变短，稳定期的时间延长，当经过二次培养后，嗜热链球菌几乎不经过延滞期直接到达对数期，平稳期持续的时间较短，很快到达衰亡期；嗜热链球菌在超浓缩培养过程中三大营养物质的代谢规律也同它的培养过程有很大的关系，菌数多，其代谢旺盛，菌数降低其代谢速度减慢；嗜热链球菌在超浓缩培养过程中存在着明显的菌体形态变化，并可能存在着细胞凋亡，与菌体增殖和产酸规律密切相关，随着培养时间延长，培养基中营养物质变得贫乏，菌体形态变化和细胞凋亡的情况愈加明显。

With the investigation of the domestic and foreign literature systematically, the bases on the domestic and foreign present research and the comprehensive utilizations of the various knowledge of fluid mechanics in porous medium, reservoir engineering, mathematical physics, perforation completion, numerical simulation and so on, this article takes numerical simulation of gas reservoir of water solubility as the research aim which has completed following research works and obtained the corresponding research results: it analyzes the nature of the Water-soluble gas and formation water as well as the influent factors of the solubility through the study of massive materials; It establishes mathematical models three-dimension, the dual medium, the gas-water phase through the way of finite difference in the migration of water-soluble gas, which describes the entire process of release, migration and production in formation, where it considered the problems of variable bubble point; According to the numerical models of gas reservoir of water solubility it provides solution procedure that based on black oil model; It discovers that there will obtain the good effects in the lowly speed of development through simulation; the reinjection of formation water may largely enhance the produce degree of water-soluble gas when we consider reinjection in simulator; It considered the influence of perforated completion on development so as to increase the simulator"s versatility, It discovers that the simulator may reflect the conditions of development when we exanimate he simulator"s reliability with the empirical datum.

本文以水溶性气藏数值模拟研究为研究目标，在系统调研国内外文献、深入分析国内外研究现状的基础上，综合利用渗流力学、油气藏工程、数学物理方法、射孔完井以及数值模拟理论等多方面的知识，完成了以下研究工作并取得相应的研究成果；①通过对大量的资料调研，分析了水溶气、地层水性质、储层地质性质以及影响气体在水中溶解度的因素。②考虑到由于高压产生的大量水力裂缝，采用有限差分方法建立水溶气运移的三维、双重介质、气-水两相全隐式数学模型，该模型描述了水溶气在地层中的释放、运移和采出的整个过程。③在原有黑油模型的基础上，根据水溶性气藏数值模型编制了该数值模型的求解程序，该程序可以求解单重、双重介质两种情况。④通过模拟不同开采速度对水溶气开发效果的影响，发现开采速度较慢的时候可以取得较好的开采效果。⑤在模拟器中考虑了注水对水溶性气藏开发的影响，地层水回注可以大幅度提高水溶气的采出程度。⑥为增加模拟器的通用性，在模拟器中考虑了射孔完井方式对开采的影响。⑦检验模拟器计算的可靠性，发现在使用实验数据对水溶性气藏进行模拟时，模拟器可以很好的反映气藏开发的状态。

Making implicit logical entailment explicit may, to put it in Kant's terms, increase our explicative knowledge, but we are looking for expansive or ampliative knowledge.5 There must then be some point at which the process of simple deductive inference is disrupted, and a synthetic or ampliative move is made.

作出固有的逻辑蕴涵的显示，按Kant的术语，可以增加解释性知识，但我们寻找的是扩展的知识。那么必须有点东西使得简单的演绎断裂，作出了综合或扩展的推进。

Because PCR amplification is a exponential process, any subtle disparity in the starting reaction mixture will lead to remarkable difference at the end point.

由于PCR扩增是一个指数过程，任何一个环节的微小差异都会显著改变扩增产量，因此理想的定量PCR应该设立内对照。

The network is exterior the main factor that the gender is influence network product requirement, preference of people basis oneself selects network product, and the network that chooses a process to affect a product again is exterior sexual size, network product market is so balanced be consumer preference do not move a point.

网络外部性是影响网络产品需求的主要因素，人们依据自身偏好选择网络产品，而选择过程又影响到产品的网络外部性大小，所以网络产品市场均衡是消费者选择的不动点。

The end point of this process is extreme form of maladjusted behaviour called psychosis.

终点这一进程是极端形式的适应行为称为精神病。

The formation process and numerical simulation study about the fan delta in Baimiao gas field constitutes the second key point of this paper.

Compared to the germanium, a common material used in infrared field, chalcogenide glasses possess the characteristics of low-cost and the little value of dn/dt. Besides, it is amorphous glass, which is produced the spherical and aspheric lens by using a molding process instead of single-point-diamond turning. Thus the mass manufacture cost of infrared lens will drop obviously, the stability and consistency of product is guaranteed.

相对于红外领域常用的材料单晶锗，硫系玻璃不但具有低成本，折射率随温度变化小的特点，而且，由于它是非晶态材料，可以用精密的模压工艺来代替用于晶体材料的单点金刚石车削工艺，其批量加工的成本得到了大幅的降低，产品的稳定性，一致性也得到了明显的提高。
