为了在水介质中获得高固含量的聚丙烯酰胺，通过无皂乳液聚合制备了一系列不同单体比例的丙烯酰胺-苯乙烯的共聚物胶乳，固含量达50％，稳定性好，胶乳粒子大小均一，具有一定的触变性。

This paper studied the effect of pollen rations on duodenum configuration and structure of growing-finishing swines, including the effect on the length and figure of intestinal villi, the length of duodenum secretory, amount of plasma cell and aggregated lymphoid nodules in membrana propria.

研究了蜂花粉对生长肥育猪十二指肠形态及组织结构的影响，考察了不同比例的蜂花粉对十二指肠绒毛长度及形态、肠腺长度、固有膜中的浆细胞、集合淋巴小结的影响。

Moreover, the relative percentage of each type of oxane bonds in the sample of APS-modified LDHs can be determined from their relative peak intensities; these results are summarized in Table 2.The oxane bonds attached on surface of AL-M can be mainly attributed to bidentate (T2)and tridentate(T3)types.

此外，相对比例的每种类型的oxane债券样品中黄芪多糖改性水滑石可确定其相对峰强度；这些结果的摘要列于表2 oxane债券所附表面的Al - M可以是主要原因以双齿和三齿（的T3 ）类型。
