Demonstrated by adsorptive capacity and adsorptive energy, polyacrylamides have strong interaction on mineral surface with similar action mode to that of starches, for example, hydrolyzed polyacrylamide and hydroxamic acid polyacrylamide mainly by chemical force, cationic polyacrylamide by electrostatic force and hydrogen bond, nonionic polyacrylamide by hydrogen bond, while amphoteric polyacrylamide embodying both the characters of anionic and cationic one.

聚丙烯酰胺类化合物在矿物表面的吸附能以及吸附量均显示出药剂与矿物间存在的强作用，作用方式与淀粉类药剂相似：阴离子聚丙烯酰胺、羟肟酸聚丙烯酰胺主要靠化学作用，阳离子聚丙烯酰胺借助静电力和氢键，非离子型的聚丙烯酰胺则主要是氢键作用，两性聚丙烯酰胺同时具有阴离子和阳离子聚丙烯酰胺药剂的作用特点。

Each starch reagent has its own mode of action on mineral surface, such as primary starch mainly by hydrogen bond, cationic starch by the co-action of hydrogen bond and electrostatic force (for minerals with negative charge on its surface), while carboxymethyl starch, hydroxamic acid starch and dialdehyde starch principally by chemical force accompanied with hydrogen bond and electrostatic force in part. Such chemical forces ensure the close adsorption of reagent on diaspore surface and enforces the hydrophilic of mineral surface. Also the branched chain enable the starch to cover the collector adsorbed on mineral surface, so as to depress diaspore furthermore.

不同淀粉药剂在矿物表面表现不同作用，原淀粉主要是氢键的作用，阳离子淀粉是氢键和静电力的共同作用，羧甲基淀粉、羟肟酸淀粉和双醛淀粉离子性药剂与矿物间的作用除了氢键、静电力外，更重要的是与矿物表面金属离子间产生的化学作用，使药剂能牢固地吸附在一水硬铝石矿物表面，增加矿物表面的亲水性，同时，淀粉支链结构的存在，使它能够掩盖吸附的捕收剂，达到抑制一水硬铝石的目的。

Heterosis making use of the male sterile breeding be able to save large amount of emasculation labour,ensuring that seed purity.It is possible that breeding can be solved while the trend of single tea varieties and genetic breeding the problem of insufficient resources.

利用雄性不育育种可以节约大量母本去雄的劳力，保证种子纯度，充分发挥杂种优势，同时可以解决育种中存在的茶树品种趋向单一化和遗传育种资源不足的问题。

According to cognition on infectious diseases,more emphases should be paid on strengthening health education for the men,the elder,the lower educated ones in the countries,at the same time,it is important to strengthen skills,operation instruction and cultivation of public health staffs.

Meanwhile the function of antioxidant defense system increased to enhance the ability for clearing free radical and antagonized the damage to organism from free radical. So the activity of GSH-Px and T-AOC enhanced. But the compensative ability was limited and the activity of GSH-Px decreased abruptly and the T-AOC was not increased further in cerebellum of chicken with encephalomalacia. This showed that it existed the exhaustion of GSH-Px in cerebellum of chicken with encephalomalacia.

在体内自由基蓄积的同时，机体抗氧化系统功能出现代偿性增强，提高自由基的清除能力，以对抗自由基对机体的损伤，表现为GSH-Px活性和T-AOC的增强，但机体的代偿能力是有限的，发病雏鸡小脑中GSH-Px活性的突然降低和T-AOC的不再增高，表明GSH-Px在发病雏鸡小脑中存在耗竭现象。

This article take the county territory economy development is the comprehensive construction well-off society s key in as the starting point, the encompassment "the strength county territory economy" the spirit, according to "five overall plans" the principle, through is connected economical theory and so on development theory to the economic in, comparative ad...

本文以县域经济的发展是全面建设小康社会的关键所在为出发点，围绕"壮大县域经济"精神，按照"五个统筹"原则，通过对经济学中相关经济发展理论、比较利益理论、区域发展理论等理论的研究和认识，结合延边朝鲜族自治州的实际，分析了延边州县域经济发展中存在的问题和阻碍县域经济发展的原因，以"农业是稳定的基础，工业是发展的出路"为主线，以政府在市场经济和经济发展中的定位为主要内容，强调了制度在经济发展中的关键和保障作用，衡量一个制度是否有效率的标准应是更多的机会公平和更多的结果效益；强调了在欠发达县域经济中，经济要取得大的和长足的发展，稀缺资源应得到充分的利用、并应向有较大前向效应的工业发展倾斜的观点，并在此基础上指出了欠发达县域经济的发展方向是传统中小工业，同时，针对以往的一些促进经济发展的政策提出了一定的改进的意见；强调了在市场经济条件下，必须更加注重社会保障机制。。。
