细胞学说在十八和十九世纪的发展，促进生物学各个方面的研究开花结果。

After years studying the microscropic structure of plants, he proposed his cell theory Contributions to Phytogenesis(1838), in which he stated that the various plant structures are all composed of individual cells.

经过多年对植物显微结构的研究，他在1838年发表了的《植物发生论》中提出了细胞学说，指出细胞是构成植物体各种结构的基本单位。

Then, a correlation of liquid thermal conductivity with the heat of vaporization was derived by introducing the cell theory for liquids .

将所得模型结合统计力学理论，导出了液体的导热系数与蒸发潜热间的关系，对40种有代表性的物质(569个点)的关联，误差仅为1。

The cognition for the mechanism and treatment of recurrence and metastasis has changed with the introduction of the cancer stem cell theory, which provides a new pathway to the control of the cancer recurrence and metastasis.

This article include threepart:(1) free cell and function lump theory;(2) substance ofJingluo---- stem cell system theory;(3)the predict of ourtheory.

本文包含三部分：（1）自由细胞和功能块理论；（2）经络的实质----干细胞系统理论及"气"的实质；（3）理论的预言及穴位。

The plane wave expansion method combined with super-cell theory is used to analyze the frequency properties.

The free volume cell theory was applied to derivative the formula of activity coefficients of liquid binary solution at arbitrary temperature. The Monte Carlo algorithm was employed to calculate the non-liner equations, then the free volume parameters were directly correlated to the activity coefficients of liquid binary, ternary, quaternary and quinary solutions at arbitrary temperature. The three dimensional diagrams of a-x-T diagrams representing the changes of activity with those of temperature and concentration were plotted.

由自由体积胞腔理论推证了某温度下两组分的活度系数关联式；引入MonteCarlo非线性方程解法，通过无限稀释溶液的实验活度系数数据直接得到自由体积参数和二元系及多元系液态金属溶液在任意温度下全浓度范围内的活度数据，构筑了直观反映活度随温度和浓度变化的a-x-T三维图形。

Based on a lot of experiments, it shows the distinct error between classical theory curve which express the relation of cell diameter, cell density and foam tensile strength , tensibility tensile product and re-spring degree and experiment curve. It also can＇t explain the relation of hole degree , area of cell wall with above four mechanics parameter. But the sub-cluster scale theory was demonstrated successfully to explain the relation of cell structure and foam mechanics property on different mold temperature, mold pressure, mold period and different chemical blowing agent, blowing activator content.

通过大量的实验结果理论分析表明：以往的经典理论存在着很多不足之处，它不能有效地解释孔径、泡孔密度与抗拉强度、断裂伸长率、断裂功、及回弹率之间的理论曲线与实验曲线之间的偏差，也不能解释空隙度、泡孔壁厚与上面四者之间的关系，而群子标度理论则成功地论证了在不同模压温度、模压压力、模压时间及不同用量发泡剂、发泡促进剂条件下泡体力学性能与结构之间的相关性。

In the sub-cluster scale theory, R1 indicated the possibility which the hole skip the middle size hole to become a big cell, it would make striking influence on the tensibility ; R2·R1 indicated the well-distribution degree of cell size, it would make the notable influence on the cell density P; R2/R1 indicated the big cell and small cell exchange possibility, it would make the remarkable influence on the re-spring degree because of the different influence with the hole size.

其中R1表征泡孔越过中等泡向大泡孔缔合的倾向，它对断裂伸长率影响最大；R1·R2表征泡孔的均匀性，受泡孔密度影响较大；lnR2／R1表征体系在发泡过程中大小泡孔相互转化倾向比，由于大小泡孔对泡体回弹率贡献不同，lnR2／R1对发泡体回弹率影响较大。
