可分散的

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。

And the PLA/Chitosan/ACP barriers with additional 2 wt% chitosan still maintain 56.58 % antibacterial ability after eightieth day. The different composition of PLA/Chitosan/ACP composites was prepared by water washing solidification from NMP/water/lactic acid consolvent. After storing at room temperature for 48 hours and taking it out to obtain a shapable composites. To investigate the influence of ratio of composition with the shapable property of composites, it was analyzed by Rheometer, TGA, AFM, XRD. The result of the different APC content had different effect both water content and yield stress of composite materials. The yield stress decreased with ACP content while increases. It was derived that ions, released from ACP interact with amide groups of chitosan to form water-absorbing ionic clusters through chelating or electrostatic attraction.

另外，以聚乳酸/几丁聚醣作为基材并添加不同比例的非晶型磷酸钙，经过水洗固化后可得白色片状沉淀物，於室温下静置48小时后，复合材之体积呈现膨胀且具有可塑形之特性，以热重分析仪与流变仪分析样品之含水率与屈伏应力，结果显示不同ACP含量对复合材含水率与屈伏应力具有消长变化，而PLA/Chitosan/ACP之可塑程度与其所吸收之水份多寡有关，推测可能机制为ACP磷酸钙盐解离后之金属离子与几丁聚醣之胺基透过螯合作用或静电吸引之交互作用，形成具吸水性之离子团簇分散於疏水性之聚乳酸基材中。

结果表明，在镀液中加入适量的聚羧酸按、柠檬酸三按或十六烷基三甲基溴化铵分散剂，并通过超声分散，可得到稳定分散10h以上的复合电镀液。

Considering the influence of other loads and uncertain factors, the follows should be taken into account if the bridge erecting mode is continue to be used.(1) Strengthen beams of steel structure with orbits, especially second half part of the Bere Beam;(2) Altering the space between crossties and increasing the support in the mid of station weight beam both can enlarge the decentralization function of the load carrying on the trunk beam, but usually the latter way is more effective. When the latter way is chosen, the stiffness of the support should be diminished correspondingly. Furthermore, adjusting the height of the support would help a lot in dispersing load.

考虑到其它载荷的影响以及不可预测因素，如继续使用该类架桥方式，应做以下考虑：(1)增加钢架梁与轨道的支撑，特别是在贝雷梁的后半部分；(2)增大荷载作用在箱梁上的分散系数，可适当改变枕木间距，亦可在配重梁的中部增加支撑，后者效果会更有效，当考虑增加支撑时，同时要降低支撑的刚度，支撑如能简单地调整高度，将会对分散载荷起到非常大的帮助。

If they have been scattered and can nowhere be found, it is our will, supported by the penalty of excommunication or ecclesiastical interdict to be automatically incurred by the lands and domain of the ruler, that, after a just estimate has been made about them, the said prelates receive satisfaction through those who carried out the said sequestrations, applications or dispersals or who gave orders for them to be carried out; and further, that their goods and the goods of those subject to them, wherever these may be found, may be seized and held if, after being warned, they refuse to obey.

如果它们已经被分散，可没有找到，这是我们的意愿，得到了惩罚绝罚或教会阻截自动招致的土地和域的统治者，在一个公正的估计已取得了他们，上述主教得到满意通过这些谁进行了说sequestrations ，应用程序或分散或谁给了订单，他们将要进行；并进一步，他们的商品和货物的这些问题给他们，这些地方可能会发现，可能被没收并举行后，如果被警告，他们拒绝服从。

In this report, half-esterification between these pendent hydroxyl groups of hydroxyl-PU and maleic anhydride could lead to new pendent groups, carboxylic groups. These highly polar carboxylic groups in the side chain of PU could play the role of internal emulsifier. They had self-dissociation ability in the water or were neutralized first by appropriate amount of base. Then, PU bearing carboxylic group could dispersed steadily in the water, named aqueous-based polyurethane dispersion.
