The latest chemical product prices fell, demand has not really visible downstream, the short-term rise in oil prices in the channel, in which phase fluctuations, we continue to be optimistic about with anti-cyclical businesses and new materials, anti-cyclical embodies New Chemical Materials decrease in prices of raw materials is less than the decrease in prices of raw materials at the same time, the cost shift ability, to maintain price stability; civil explosive materials companies fell as a result, prices, countries can enjoy the benefits of; domestic urea production capacity excess of export disruption, high product costs, industry consolidation is inevitable, so concerned about the urea industry with technical advantages and cost advantages of urea enterprises: China Shandong Hengsheng; Although the overall situation of excess nitrogen, but because of the regional characteristics of the domestic fertilizer domestic part of the region will be in a high urea prices, the relevant listed companies will benefit from, such as the Liao Tung Chemical; compound assets as light industry, with the weak cyclical characteristics, the stability of industry profitability, industry leaders concerned about the compound: para Tian shares ; potash by the international market, short-term decline of domestic potash fertilizer prices would have difficulty, Salt Lake Potash in 2009 will be guaranteed a profit, Salt Lake Potash concern.
最新化工产品价格出现下跌，可见下游需求并未真正起来，短期石油价格处在上升通道，在这种上下波动阶段，我们继续看好具有抗周期性的新材料企业，抗周期性体现了化工新材料的产品价格下降幅度小于原料的下降幅度，在原料价格上涨同时，成本转嫁能力较强，价格维持稳定；民爆企业由于原料下跌，价格上涨，可以享受国家指导价的益处；由于国内尿素产能过剩，出口受阻，产品成本居高不下，行业整合在所难免，因而关注尿素行业内具有技术优势和成本优势的尿素企业：华鲁恒升；虽然氮肥全局过剩，但由于国内化肥的区域性特征，国内部分区域尿素价格将处于高位，相关上市公司将因此受益，如辽通化工；复混肥作为轻资产行业，具有弱周期性特点，行业盈利稳定，关注复混肥行业龙头：芭田股份；钾肥受制于国际市场，短期内国内钾肥价格恐难下跌，09年盐湖钾肥盈利将会有保证，关注盐湖钾肥。

Firstly, wettability and adhesive properties of the major soy protein components conglycinin (7S) and glycinin (11S) after urea modification were characterized. Modified 7S and 11S soy proteins were evaluated for gluing strength with pine, walnut, and cherry plywood and for wettability using a bubble shape analyzer. The molecular structure change was studied by chemical analysis, DSC and Rheometer. The results showed that different adhesives had varying degrees of wettability on the wood specimens.
液滴形状分析结果表明不同的胶粘剂在不同的木块上有不同的湿润性能，7S蛋白经过尿素变性后在胡桃木和樱桃木上有较好的湿润性能，11S蛋白经过1 mol/L尿素变性后在松木上有好的湿润性能。1 mol/L尿素变性使得11S蛋白在三种木块上的胶粘强度在所有胶粘剂中为最大；3 mol/L尿素变性使得7S蛋白在胡桃木和樱桃木上的胶粘强度比11S的大，但在松木上的胶粘强度则是11S/3M高于7S/3M。
