It was established that, the fish skin was stirred two times with 2.5% or 5% NaCl solution at a ratio of material to solvent of 1:10 at about 5℃ for 12h, about 5.9%, 6.7%, 9.1% soluble non-collagenous protein could been separated from skin of silver carp, bighead carp and grass carp, then by homogenizing with acid at a ratio of material to solvent of 1:30, about 78.9%, 84.1%, 82.0% of collagen from skin of silver carp, grass carp and bighead carp could be extracted by acetic acid or citric acid.

结果表明，鲢、鱅鱼皮经2.5％NaCl溶液(1：10)，草鱼鱼皮经5％NaCl溶液(1：10)，温度5℃左右，12h磁力搅拌处理二次，除去的可溶性蛋白分别占原总蛋白的5.9％、6.7％、9.1％。鱼皮再经加酸(1：30)溶胀、均质处理后，即可得到鱼皮胶原蛋白的粗提取液，鲢、草鱼鱼皮的酸提取回收率以醋酸为最高，分别为78.9％、84.1％，鱅鱼皮以柠檬酸为最高，约为82.0％。

CTX ip 0.06 mg/kg, 0.12mg/kg significantly reduced the errors of the mice in Y-Maze test, decreased the mices training times, shorten the escape latency in Shuttle box test. In Step-down test, CTX ip 0.06mg/kg, 0.12mg/kg increased the escape latency and reduced the number of errors, CTX also reduced the searching platform latency and swim path-length in Morris water maze test with mice.

实验发现，CTX能明显增加热刺激引起的疼痛闭值，明显减少醋酸引起的扭体次数，并能显著增加小鼠在Y型迷宫实验中的正确反应次数，减少在穿梭箱实验中小鼠重新训练至学会标准的训练次数及小鼠的反应时间，能增加小鼠在跳台法中的潜伏期，减少错误反应次数，减少小鼠在Morris水迷宫实验中的寻台时间和游泳路程，以上效果均表现出明显的剂量依赖性。

Objective:A GF-AAS method was established for the determination of lead in tipping paper,filter plug wrapping paper,diacetate cellulose tow,polypropylene fiber tow,glycerol triacetate for cigarette,polypropylene fiber tow filter rod adhesive,polyvinyl acetate emulsion adhesive,hot melt adhesive.

目的：建立了接装纸、成形纸、醋纤丝束、聚丙烯丝束、三醋酸甘油酯、聚丙烯丝束胶粘剂、白乳胶、热熔胶等8种滤嘴用卷烟材料中铅的测定方法—石墨炉原子吸收光谱法。

The invention is obtained by adopting a hydrothermal and pyrogenic decomposition method which adopts Zn (CH3COO) 2 . 2H2O, deionized water and ammonia as raw materials; zinc acetate nano ribbon-shaped material is first obtained by a hydrothermal method and is then treated with pyrolysis in air so as to obtain the ZnO nano ribbon-shaped material.

本发明采用水热和高温分解方法制备得到，即，以Zn(CH 3 COO) 2 2H 2 O、去离子水及氨水为原料，先利用水热法制得醋酸锌纳米带状物，然后在空气中高温加热分解而成。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
