在一个对水溶性聚合物要求的指标上
1）发现screen factor，其值要求在15-25之间，无量纲，字典中是屏蔽因子或过筛系数的意思，可是这指标是拿什么测的呢？

2）分子量单位是mln，指的是什么？

3）动力粘度 at D=9c-1(-1是指数），这个D指的是什么？剪切速率么？

A "screen factor" has been defined, which relates to the ability of the fluid to flow under such conditions. The screen factor is a measure of the viscoelastic behavior of the polymer fluid.
The screen factor is defined as the ratio. between the flow time of the polymer solution and the flow time of the solvent as a. given volume of the solution passes through a pack of five 100-mesh screens.
Screen factor is the ratio of the time taken for a given volume of polymer solution to flow through five closely packed, randomly oriented, 100 mesh (U.S. Sieve Series) stainless steel screens, compared with the time required for the same volume of water to flow through the screens. The screens used are 0.25 inch in diameter, and their packing is adjusted until the time taken for 40 cc. of water to flow through them is between 8 and 11 seconds. Screen Factor has no absolute value, but tests have shown that the efficiency with which an aqueous polymer solution can displace oil from a subterranean formation is related directly to screen factor. A complete description of screen factor may be found in an article by B. L. Knight entitled "Reservoir Stability of Polymer Solutions", Journal of Petroleum Technology 25 (5), p. 618, (1973).

B. L. Knight entitled "Reservoir Stability of Polymer Solutions", Journal of Petroleum Technology 25 (5), p. 618, (1973). 哪位能给全文呢？
