Some conclusions can be obtained from the analysis of test results:(1) Under long-term cycle loading, the strain rate of soft clay decreases with time. The logarithmic relationship between strain rate and time is linear.(2) The effect of initial static deviator stress and cyclic shear stress coupling and the drained condition have much influence on stain rate of residual strain.

通过试验结果分析可得：（1）在长期循环荷载作用下，黏土的应变速率随时间的增大而减小，应变速率对数与时间对数间的关系可用直线描述；（2）初始静偏应力与动偏应力的耦合作用以及不同的排水条件对黏土残余应变速率有较大程度的影响。

The analysis of the results show as follow:(1)The consolidated-undrained creep, which doesn't include the volume strain, can be expressed by logarithmic functions as a type of under a different deviator stress.(2)The shear creep behaves in a linear elastic character in a lower stress level, and it is a nonlinear behavior in a higher stress level.

分析表明：(1)固结不排水蠕变中没有体积变化，不同偏应力下剪切蠕变可用对数形式表达；(2)固结不排水剪切蠕变在低应力水平下表现为线性粘弹性，而高应力水平时则具非线性的特性。

So, it can be established the single logarithmic model to characterize the soil water diffusivity of the Nanxiaohegou basin.

因此，可以用参数B作为反映地貌类型的指标，应用于区域土壤水分扩散率的估计中。

The resulting curve breaks into two approximately straight lines. By purely empirical curve fitting method we obtain two straightline equations. Secondly, the recurrence interval and"rain-strength" relation curve on logarithmic paper will also br...

而在对数坐标轴内，频率和雨力的关系曲线，也分裂为二，分别用二次曲线和直线来配合，综合而成均方差很小的上海暴雨公式，以供市政规划设计的应用。

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。

Two kinds of models by estimating pool equations and panel estimation have been constructed. Based on the idea of Reduced Form Model, by adopting lags-adjustment or not, time-series dynamics models of the fluctuation of urban residential real estate market, in which the endogenetic and the exogenous sensitive variable include, have been estimated. In logarithmic form the models are applied in a case.

同时，借助缩约模型的基本思想，将住宅市场波动的外生和内生敏感性因素纳入到城市住宅市场的动态分析中，从纵向角度引入非时滞调整和时滞调整的两类模式，构筑了不同形式的住宅市场波动的时序动态模型，采用对数模型估算案例城市商品住宅市场的时序动态波动状况。

The logarithmic function is defined as the inverse of the exponential function .

对数函数是作为指数函数的反函数来定义的。

The most important exponential function is ex, the inverse of the natural logarithmic function.

最重要的指数函数是ex，即自然对数函数的反数

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

We have battled against the odds in a province that has become increasingly violent.

我们对在一个争夺日益激烈省的可能性。
