The migration of dinoflagellate cysts with transapical archaeopyle su-ture from sea water to fresh water lasted relatively long.

具过顶古口缝的沟鞭藻囊孢由海水向淡水迁移持续的时间较长。

The order of elution, as well as the migration time and separation efficiency of these compounds changes with the acidity of the solution, which suggests the disassociation of the hydrogen on the secondary amino group in these compounds.

它不仅影响化合物的迁移时间和分离效率，还改变其出峰顺序，这与碱性条件下化合物仲胺基上氢的电离有关。

BMSCs may reverse the disbalance of Th1/Th2 cells by regulating the cytokines production to take an important part in treatment of EAE.

在体外BMSCs通过化学诱导可以向少突胶质细胞分化；在体内BMSCs能向病变部位迁移，并部分分化成少突胶质细胞，同时BMSCs通过调节免疫系统的炎症细胞因子表达、CD4+和CD8+T细胞数和Th1和Th2细胞平衡，对EAE起治疗作用。

Stoppage of the use of the land due to reasons such as disbandment and moving.

因撤销、迁移等原因而停止使用土地的。

Stoppage of the use of state-owned land previously appropriated as a result of disbandment or moving of the unit; and

You will be migrating to a new and disciplined approach to controlling your company's data.

您将被迁移到一个新的和有纪律的方式来控制你的公司的数据。

This makes more and more people pay more attention to studies and applications of numerical simulation in thermal recovery. In this research, we have developed a reliable mathematical model for thermal recovery, which takes a full consideration of the effect of viscos, gravitical and capillary forces on the three-phase flow of gas, water and oil, the effect of the temperature on the medium characteristics of liquid and solid, the phase equilibrium of gas-liquid in each component, heat transportation including connection, conduction and radiation as well as heat losses in both the overburn and underlying strata. In the space discreation of the mathematical model, we have proposed a new method based on the improvement of the conventional nine-points difference approximation, which has a higher difference accurancy.

本项研究以热力采油的主要机理为基础，充分考虑在粘性力、重力和毛管力作用下油水气三相流动，考虑温度对各种流体和固体介质物性的影响，考虑每一组分中汽液两相的相平衡，考虑热在地层中的传导、对流和辐射以及上下盖层的热损失，利用热力学第一定律、质量守恒定律和流体迁移定律，建立了正确可靠的注蒸汽数学模型；在对数学模型进行空间离散时，利用控制有限体积积分法，对以往的九点差分近似作了合理的改进，使其具有较高的差分近似精度：结果表明，该公式的近似精度要比以往文献中所给的九点差分近似精度高，可以认为，在油藏数值模拟中，如果遇到非均质情况，使用这种九点差分近似更合理。

In this paper, the effect of population dispersal and nonlinear incidence rate on the spread of a disease is investigated.
