The polymerization of preparing PDA could be impacted by allyl chloride, allyl alcohol and allyl aldehyde. The content of allyl chloride, allyl alcohol and allyl aldehyde in the DMDAAC monomer solution varied from 0mg/kg to 1000mg/kg, their intrinsic viscosity of PDA descended from 10.3dL/g to 8.0dL/g, 6.8dL/g and 8.8dL/g respectively. The polymerization of preparing PDA could be carried out well in the case the content of NaCl, active carbon, yellow residua and low molecular polymer of DMDAAC were less than 10000mg/kg, 1000mg/kg, 1000mg/kg and 50000mg/kg respectively.

单一杂质含量变化对聚合产物PDA特征粘度影响的研究结果表明：在DMDAAC单体溶液聚合反应过程中，当Fe~(3+)、Fe~(2+)和Cu~(2+)含量分别达到7mg／kg、9mg／kg和5mg／kg时无法得到聚合产物PDA胶体；当烯丙基氯、烯丙醇、烯丙醛含量分别从0mg／kg增加到1000mg／kg时，聚合产物PDA的特征粘度从10.3dL／g分别下降到8.0dL／g，6.8dL／g和8.8dL／g；活性炭和黄色物质含量在1000mg／kg以下，低聚物含量在50000mg／kg以下以及氯化钠含量在10000mg／kg以下时产物PDA的特征粘度降低变化量不超过0.2dL／g。

Non-diapiric, the overpressured top boundaries in the south and the margin of Yinggehai basin are often deep-buried, and are distinctly controlled by the formations and their lithologies.

以36对SSR引物的37个位点和2708份核心种质材料进行取样比例的研究结果认为，随着压缩比例的增大压缩群体的基因多样性指数先升高再降低，等位基因的数量和等位基因覆盖率持续下降并且速率逐渐加大。

Silver grass is weakly acidic, pH value is between 5.53 and 6.49, alkali buffer capacity is between 0.89ml and 3.31ml and acid buffer capacity is between 11.52ml and 17.38ml; To the wet ability of silver grass, the under-parts of stem are better than upsides, the inner surface of stem is better than surface, the wet ability of leaf is between surface and inner surface; compare with wood and wheat straw, the wet ability of silver grass is worse than that of wood but better than that of wheat straw.

荻草的化学成分主要是由纤维素、半纤维素、和木质素以及抽提物组成，在不同部位，各个化学成分的含量也不相同；荻草呈弱酸性，pH值在5.53～6.49之间，荻草的碱缓冲容量在0.89ml～3.31ml之间，酸缓冲容量在11.52ml～17.38ml之间；荻草茎秆下部的润湿性好于上部，荻草茎秆内表面的润湿性要好于外表面，荻草叶子的润湿性介于内外表面之间，与木材相比，荻草的润湿性不如木材，但要好于麦草；荻草茎秆下部的纵向抗拉强度要高于其上部，热处理15分钟后，茎秆下部的强度有所下降，茎秆上部有所提高，并没有表现出水热处理后荻草单元强度突然骤降的结果

Compared with the bulk Ba8Ga12Zn2Ge32 material prepared by melting method combined with SPS (MM+SPS sample), the bulk Ba8Ga12Zn2Ge32 material obtained by melting method combined with MS and SPS (MM+MS+SPS sample) has higher carrier concentration and lower carrier mobility at room temperature.
