变度

When the undrawn films were annealed atthose temperatures, the morphologies in the lamellar crystals had change. WAXDand iR studies shown that the crystallinities incrcand, dimensions in (002) and(020) normals increased while that in (200) fold had slight decreases. The rela-tionship between the orientation of the drawn UHMWPE gel-films and the struc-ture changes and the optimum drawing temperature had been disscussed.

通过IR及X－ray衍射等方法研究发现，拉伸前用不同温度退火处理后，凝胶膜的片晶微结构产生明显变化，在对应于超高拉伸温度范围内，其结晶度增加，微晶的c和b轴方向尺寸变大，而a轴方向的尺寸减小，从理论上对这一变化过程作了考察，并讨论了超高拉伸取向性与这些结构变化的关系以及可超拉伸取向性的最佳温度范围。

The proposed algorithm can preserve invariability on the geometric structure: the eigenvectors which are neighboring each other in the original space will maintain the same attribute in low-dimensional space; on the contrary, the unsimilar eigenvectors become apart farther each other. Therefore, the description generated by our algorithm can show the interrelationship between features and has strong robustness.

所提出的算法能保持描述器之间的几何结构不变：原空间中邻接的描述器映射到低维空间后保持邻接，而不相似的描述器映射后区分度更大，所以该算法所生成的描述器能表现特征点之间的内在关系，具有很强的鲁棒性。

While other reaction conditions were setted, viscosity and yield of the product P were determined by Ubbelohde viscosity meter in different temperature;By parity of reasoning,viscosity and yield of the product P were determined in different initiator concentration、monomer concentration and monomer ratio.

固定其它反应条件不变，用乌氏粘度计测定了在不同引发剂浓度下产物P的特性黏度及产率；以此类推，测定了在不同单体浓度、单体配比条件下产物P的特性黏度及产率。

By application of dissipative structure theory, the order degree entropy function of water resources system is established, and the rationality is testified. The water resources evolvement direction can be distinguished by finding out the change tread of order degree entropy. At the same time, the entropy change is also the basic criterion of weighing the validity of control.
