The second was to compare the effects of the different floating liquids on the destruction of rabbit coccidia oocysts. The results indicated that magnesium sulfate solution showed the lowest rate of coccidia oocyst destruction at 20 min; saturated salt water had the greatest rate of destruction. The destruction increased with time; in the saturated salt water and urea solution damage or deformation of a few coccidia oocysts at were observed 60 min.

The effects of the surfactants, trioctyl phosphine oxide, sodium dodecyl sulfonate and hexadecyl trimethyl ammonium bromide, on the extraction rate of Co^2^+ were investigated. The acceleration in the kinetics in contributed to the associated molecule~2 TOPO taking part in the extraction process directly. The decrement effects of SDS or CTMAB on the rate of extraction kinetics of Co^2^+ with HDEHP were also observed, which caused by the adsorption of molecules of SDS or CTMAB on the interface and decreased the interfacial adsorption amount of HDEHP. In addition, the extraction rate was reduced by a bigger margin in HDEHP-SDS system. This can be explained in terms of the formation of an electric field at the interface.

研究体系中加入不同表面活性剂所引起萃取速率的不同改变：三辛基氧化膦因与HDEHP形成可萃取的Co^2^+活性分子缔合物，降低了萃取过程活化能而使反应加速；十二烷基磺酸钠和十六烷基三甲基溴化铵因占据发生萃取反应的界面区，减小了HDEHP与Co^2^+反应的机会而使反应减速； SDS还因其在界面形成较强的负电场，造成Co^2^+的附加势能而使萃取速率有更大幅度的降低。

The Federal Reserve said consumer borrowing rose at a seasonally adjusted 2.4% annual rate in February to $2.54 trillion, half the 4.9% pace recorded in January.

Lb a1在1龄、2龄、3龄、4龄若虫及成虫中的表达水平分别是Lb a8的2.03、2.55、4.77、6.54、和5.28倍，且它们之间的差异均达到显著水平(P＜0.05)。5温度对无色书虱发育和繁殖的影响通过比较无色书虱在不同温度条件下的发育速率、存活率、内禀增长率等生命参数以明确无色书虱在不同温度条件下的发生发展规律。

Variety widely cultivated in south China,were studied by foliar 1.5 g L-1 CCC application after pot planting virus-free plantlets at the stage of budding.It was found that at the stage of tuber bulking,spraying CCC plays a prominent regulating role in the photosynthesis of Zhongshu 3.The net photosynthetic rate,stomatic conductance,intercellular CO2 concentration and transpiration rate of leaves were superior to those of the control.CCC markedly increased the contents of chlorophyll and carotenoid.CCC significantly increased the leaf photosynthetic productivity and improved economic yield.
