急剧变化

This model was finely fitted by theexperimental results and was used to calculate the activation area,which was 0.127 〓/mol with little dependence of subphasetemperature. The positive activation area indicate that there is anincrease in area when the activated complex is formed, increasingthe surface pressure should decrease the rate constant and that theactivated complex is unimolecular in nature.

在一系列实验曲线的基础上，我们提出测量的面积变化应该由聚合中分子结构变化引起的急剧的瞬时面积变化与随后的与此面积变化相反的弛豫过程两部分组成，并据此提出一种反应动力学模型，此模型与实验结果相当吻合，此模型用于处理聚合速率的紫外光强依赖性，得到聚合速率常数近似与光强成二次幂指数关系；此模型也被用于计算活化面积，发现活化面积为〓，几乎与温度无关。

Comparing the electrolyte concentration shifting along the time with the membrane surface potential shifting along the electrolyte concentration, the crimple phenomenon is related to the shift rate of electrolyte concentration and to the shift range of the membrane surface potential.

通过模型计算环境中平均盐浓度随时间的变化及实验测量膜表面电位随盐浓度的改变，我们发现皱褶的出现及形变程度与盐浓度变化的急剧程度有关，也与膜表面电势变化幅度有关。

The evolvement of Diffluence River is the more complicated than Single River, because the diversion"s thing is changed with channel"s distortion. The river diversion is the general reflection of a good many factors, which mutually influence and adjust. In particular, when main channel occurs scouring-silting change, which causes the movement of water, sediment, and river bed in river system, the diversion will more be changed, with the study on division of discharge and sediment been further into, some practical engineering problem are solved.

目前，在对河道分流的认识与治理开发上虽取得了不少成绩，但随着社会经济的发展，人们对分流河道演变规律的认识与治理要求越来越高，随着人类对河流改造活动的加剧，河道的水沙条件可能发生急剧的改变，这些变化有可能使分流分沙的缓慢变化加剧，甚至改变原来的分流规律，许多研究者对分流分沙进行了较深入的研究，并能较好地解决了工程实际问题。

Theobserved strain is 10~2 times as local point strain at the same observed stress.This indicates that macroscopical symmetrical rock is quasi-brittle materialwith microcosmic heterogeneousness and its macroscopical mechanicalbehavior is the results of reciprocity and magnification between microcosmiccharacteristic, not simple sum.(4) The degree of irregularity of strain increases with the number of cycle.But degree of irregularity of transverse strain fluctuates larger at the samecycle. Moreover degree of irregularity of transverse strain is larger than that ofaxial strain. This shows that deformation and failure of rock is process ofevolvement of small crack. Small crack evolves from even and out-of-orderstatus to heterogeneous and ordinal status.(5) Ultrasonic speed decreases with the number of cycle. The decreasecourse is such: Firstly, ultrasonic speed fluctuates in a steady scope in somecycles; And then ultrasonic speed quickly decreases to a certain more smallvalue; Afterwards in succedent cycles, ultrasonic speed fluctuates about thevalue. That is to say, ultrasonic speed fluctuates and decreases at intervals ofcycles. In deformation process of rock, quantitative change and qualitativechange of its small crack evolvement carry through crosswise.(6) Strength and modulus of rock decrease with exponential function asscale of specimens increases.

同一表观应力下，局部点应变与表观应变相差可达2个数量级，表明宏观上均匀的岩石是具有细观特征的准脆性材料，其宏观力学行为是细观特征相互作用、放大的综合结果，而不是简单的叠加；(4)岩样轴向应变不均匀程度和横向应变不均匀程度随循环次数的增加渐进增大，但是在同一个循环内，横向应变离散系数随应力的变化波动较大，且同一循环级别下，横向应变不均匀程度大于轴向应变不均匀程度，表明岩石内部微裂纹的演化是岩石变形破坏的本质特征，这一演化表现为微裂纹从均匀无序分布逐渐向非均匀有序发展；(5)随循环次数的增加，所有岩样内部超声波速会出现衰减，衰减过程表现为在某几次循环内超声波速在某一相对范围内波动，然后急剧减小到某一较小值，在随后的循环内，超声波速又会保持在这一较小值附近波动，即超声波速表现为波动和急剧减小间隔形式衰减，表明从宏观看来平稳的岩石变形过程，内部结构演化过程(微裂纹发展及其相互作用)却表现为均匀量变和突发质变不断交叉进行的现象；(6)岩石强度和弹性模量随尺度增大呈指数函数规律减小。

In this paper,dynamic changes of lacustrine water in the Sihu area were analyzed by using remote sensing.

采用遥感方法分析了四湖地区的湖泊水域的动态变化，分析结果表明：该地区 50年代至 80年代初由于大规模围湖造田，致使湖泊水域萎缩相当严重，80年代以后，湖泊水面急剧减少的趋势得到遏制，而 90年代以后，湖泊水面基本处于无显著变化状态。

Transcript level was not obviously different between MSTN and IGF2. The expression of MSTN reached the highest point at 7 day and droped to the lowest point at 7 weeks after birth. The expression of IGF1 arrived at the highest peak at brith, and degraded the half of the birth after 7 days. Then, the change of the IGF1 expression level was no abvious. The expression result of the IGF2 decreased to the least at 1 week and increased the max point at 3 weeks. The change regulation of IGF2 expression was showed as a wave.

其中，IGF-1表达水平最低，MHC2a表达水平最高；IGF2与MSTN表达水平相当； MSTN的表达于7天时表达水平最高，是出生时表达的3倍，随后于14天时急剧下降，于7周时降至最低水平；出生时IGF1的表达水平最高，随后于一周时降至出生时的一半，后期的表达变化不大； IGF2的表达水平于3周时表达最高，是出生时的两倍，在1周时最低。3周后骤然降低，呈现一个波浪型变化；MHC的表达出生时最高，于1周后降至原来的1/7，随后逐渐升高，但变化并不太大。

Results showed that contents of IAA and ABA in peduncle, bourse and the tissues around abscission zone among several cultivars were very different, but their trend of change was similar, IAA content decreased and ABA content increased toward harvest time for all the cultivars. Ethylene evolution in fruit of the cultivars with higher preharvest drop was evidently higher than the cultivars with less preharvest drop. Cellulase activity in the tissues around abscission zone of the cultixars with higher prehanest drop rapidly increased toward harvest time.

The results showed that different topping frequency (at intervals of 15 d, 30 d, 60 d, 90 d) had no evident influence on total wine loss, volatile acid content, T-SO2,F-SO2, wine colour, and wine pH values. Under constant temperature and humidity conditions, total wine loss was closely correlated with the using degree of Chinese barrel and the storage time in Chinese barrel. Volatile acid content slightly rose along with wine storage time. The content of SO2 dropped rapidly during 15 d after wine filling, but dropped tardily ever since. Wine colority rose remarkably during 15 d after wine filling, but climbed tardily ever since. Wine colority change was unstable, it changed wavily and depressed on the whole. In conclusion, it was recommended that the best topping interval was 90 d.
