Many data and discussions about carbonate rock dissolution in CO2 solution have been published. In this paper, special simulation experiments were carried out in order to understand the dissolution behaviors of carbonate rocks in organic acid and H2S solution. The results show that, as the temperature rises from 20℃ to 200℃, the dissolution rate of carbonate rock in organic acid increases with temperature below 90℃ and decreases above 90℃.

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.

Stage I of both male and female stone flounder appears only once in all its life, and the germ cells are comprised by spermatogonia or oogonia. The gonad from Mar to Aug keeps at stage II. The gonad index of testis at this stage is 0.037%, and the amount of spermatogonia is increased quickly. There is some linear germ plasm in the cytoplasm of spermatogina. In ovary at this stage it is mostly composed by oocyte of phase 2 which the character is the appearance of yolk nucleus, and no zona radiate in membrane. The mean GI of ovary is 1.95%. From Sep to Oct gonad is at stage III which testis is composed by lots of spermatogina and few spermatocytes, and the mean GI of testis at this stage is 0.086%. In ovary the ooctyes at phase 3 are in dominate position, the yolk nucleus disappear. And the GI of this stage is 3.35%. Both testis and ovary are at stage IV in Nov. hi testis the germ cells are in spermiogenesis, and the mean GI is 0.93%. hi ovary the oocytes are mostly at phase 4, which are filled in the cytoplasm with vitellin granule, and the zona radiate in membrane begins to formation. Nucleus moves to one side of the oocyte gradually. The mean GI of ovary at this stage is 9.37%.

With the development of embryo, Myf5 expression decreased gradually in somites in the anterior region, but remained strong in the newly formed somites; After 30 somites formed, MyoD expression decreased in the somites except the caudal somites. At the hatching stage, MyoD and Myf5 were expressed in head muscle cells and fin muscle cells. In the growing fish, Myf5 was expressed in the skeletal muscle and intestine, and in adult flounder, Myf5 was only expressed in muscle. In the growing fish and adult fish, MyoD was only expressed in muscle.

For non-intense beams,particle trajectory can be obtained by multiplying linear transport matrices. For nonlinear transport of intense beams,the influence of space-charge effect on beam transport needs to be taken into account,and self-consistent solution should be derived because of the interaction between charged particle distribution and space charge field. In the program,components and currents are divided into equal intervals,respectively,and each interval is treated as a uniform solenoid field.
程序在计算非强流脉冲束流的线性传输时,粒子的轨迹通过矩阵的直接相乘计算得出;程序在计算强流脉冲束流的非线性传输时,需要考虑束流中的空间电荷效应对束流传输的影响,在束流运动过程中,空间电荷场也在不断地变化,而且粒子运动的轨迹与空间电荷势又是相互依赖的,因此需要求得一个自洽的解,先把元件分成若干均等的区间,把电流分成若干等份,后采用束流电流迭代与元件区间迭代的计算方法。

The severe storms on the squall line had large radar reflectivity and high tops of echoes. There was a divergence at lower level, a convergence at middle level, and a divergence at upper level in the velocity cross section of the squall. The VIL (Vertical Integrated Liquid water) of the storms increased rapidly to a large value, which is a good indictor of hailstorm. When the probability of severe hail is larger than 30% according to the hail index products, a hail storm is very likely to happen. The convergence line in the boundary can trigger and intensify convections.
