The rheological character of a polymer often appears as shear-thinning. Most polymers behaviour in a solution can be explained by the polymer chain or hard sphere theory. Other than that, shear-thickening polymer solution also exists. Its behavior can be explained by dilatant theory, which suggests that the shear-thickening of the solution is due to the swelling of the polymer particles. This phenomenon often occurs in suspension or emulsion. Solution exhibits a mixed behavior can also be found whose behavior is such that shear-thinning occurs under low shear force and shear-thickening occurs under high shear force. Under this circumstance, the viscosity versus shear force graph exhibits a spoon shaped curve. The rheological study can be applied to the dispersion of paint which can predict the dispersion effect of various polymer materials in solution.

中文摘要一般高分子聚合物溶液的流变行为多半呈现剪稀(shear-thinning)的现象，而大部分的高分子在溶液中的行为是以分子链或是硬球观点来解释，另外也有剪稠(shear-thickening)现象的高分子溶液，其流变行为则是以膨胀体观点来解释，即在高剪切力下，由於高分子团体积变大而使溶液黏度升高，这在悬伏液、乳液等常见；但也有在低剪切力下，溶液具有剪稀的行为，而在高剪切力下却成现剪稠的行为，在黏度对剪切力作图时，会呈现出一个勾形曲线的图形；流变行为的探讨可应用在涂布材料的分散技术上，以推测不同的高分子溶液对分散效果的影响。

From these result of the experiment, the dynamic modeling can be simulated effectively, when the move speed of tip is faster the shear force in the tip is bigger. In the lithography process the motion of tip influence by the pile up, it leads to the serration surface of the groove, is like the surface of actual material of the cutting process.

Seven Brachionus species in Lake Jinghu were found, of which Brachionus calycflorus, B. angularis, B.diversicornis and B.forficula were determined as common species due to their higher population densities and occurrence frequency. The population density of both B.calyciflorus and B. angularis reached the peak in February and March and decreased rapidly after April, while that of both B. diversicornis and B. forficula remained high during June-September and decreased sharply after October.
