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。

Moving education of the ability that overflow a person is a theory and the course that combine actually, although at present our country already was opened,move free the school that reachs relevant major and commercialize groom orgnaization, but of real high quality not much, do not make a technology for the most part, do only groom, this kind " religion " with " produce " groom detachedly pattern exists generally weakness of strength of persons qualified to teach, originality makes experience defective, heavy academic light practice, lack is scientific the problem such as education management, groom the student that come out often is be an armchair strategist, become " academic overmatch, the weak of actual combat ".

目前应用较为广泛的模型多为集总式模型。但是,集总式水文模型有很多缺点,如不能反映实际暴雨洪水产汇流的空间分布特性,无法全面的刻画水文系统分散输入集中输出的产汇流规律等。因此为了研究和解决变化环境中的水文水资源问题,评估和检测流域的径流过程和水资源量的动态变化规律,实现水资源的可持续利用和发展战略,必须开发研制有物理基础的分布式流域水文模型。

For a higher yield, the multibranch well bore should be perpendicular to the direction of maximum principal permeability, b. for a given coalbed methane reservoir, there is an optimal interspace, by which a bigger control area and the interaction among the branches can be obtained, and c. with the extension of the branch, gas yield becomes obviously higher, while the branch length should be an appropriate value on account of the influence of coal bed boundary and wellbore pressure drop. The research results have guiding significance for well pattern optimization and efficient development of coalbed methane gas.

结果发现:为了获得较高的产能,多分支井的井筒应垂直于最大主渗透率方向;对于给定的煤层气藏,存在一个最优的分支间距,既能保证较大的控制面积,又能保证分支间的互相影响;随着分支长度的增高,产气量也显著增大,但是考虑到煤层边界和井筒压降的影响,分支长度也应该有一个比较合理的值。
