Obviously, large amounts of cyclin B1 existing in spermatids has no effect on adjusting the activity of 〓 kinase, which may be just a signal of the end of cell division and/or a necessary factor for the initiation of the metamorphosis of spermatids. Abdominal high temperature inhibit efficiently the translation of cyclin B1 and 〓 in the spermatogonia and pachytene/diplotene primary spermatocytes.

显然，精子细胞中大量存在的cyclin B1蛋白不会起到调节〓激酶活性的作用，而是作为一种细胞分裂完成的信号，为启动精子细胞变态所必需；（4）腹腔高温使粗线期/双线期初级精母细胞中cdc2和cyclin B1转录本的翻译受阻。

It is suggested that the emulsify is formed when the oil on the water is stretched and stacked repeatedly by the wave, during which the water is mixed with the oil and entrain into the oil; particle asphaltene forms machinery protection film between oil and water, which stabilizes the water in the oil; the asphaltene film is formed through the accumulation when the water cohere; the resin of high viscosity can intensify the film.

通过对文献资料数据和不同观点进行分析及油水运动特点的实验观察，对溢油乳化物形成机制提出新的见解认为：乳化物是原油在波浪作用下反复拉伸和堆积中发生油水混合、水被夹带入油中而形成；颗粒态沥青质在水滴外形成机械保护膜将其稳定，它是水滴凝聚受阻时在油水界面积累而成，胶质的高粘性强化保护膜起到辅助作用。

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。
