The wastewater from gum benzion production contains benzaldehyde, cyanide, gum benzoin and ethyl benzoate. When the cyanide is determined by isonicotinic acidpyrazalon method, the ethyl benzoate is distilled and goes into NaOH absorption liquid with cyanide in the process of predistillation, because its boiling point is low. Thus the absorption liquid produces a great deal of foam and feculence.

摘要］有机化工产品安息香生产废水中含有苯甲醛、氰化物、安息香和苯甲酸乙酯，在用异烟酸吡唑啉酮法对其进行氰化物测定时，由于油酯类的沸点较低，在预蒸馏过程中被蒸出和氰化物一起进入NaOH吸收液，使得吸收液产生大量泡沫和沉淀，严重干扰后续比色测定。

The pretreatment of inhibitor was divided into two groups: discard pretreatment liquid group and reserve pretreatment liquid group. At the same time we also tested the activity of caspase3 when cell was pretreated by VerapamiK YTNF3 or TNF-3 . The results indicated that the blocking effect on Y TNF P or TNF P induced L929 cytolysis was significantly lower in inhibitor pretreatment discarding group than in pretreatment reserved group.

为了探讨细胞因子与受体结合后的信号转导速度及抑制剂发挥作用公的时间效应，我们进行了抑制剂预处理和 Y hF i及 iiiF 6预处理实验，二其中抑制剂预处理又分为抑制剂去除和保留两组。

The results show that the decalescence of catalyst bed affects the process of hydrogen peroxide catalytic decomposition greatly. If the catalyst bed is preheated or made up of materials with low thermal conductivity, that influence can be depressed. At the same time, the response characteristic of catalyst bed and the efficiency of catalytic decomposition can be improved. The low frequency pressure instability of catalyst bed occurs because of the coupling of catalytic decomposition and supplying. The decomposition plane pushes all the way through the catalyst bed during pressure oscillations, causing unreacted liquid hydrogen peroxide to be exhausted from the bed and leading to the appearance of liquid hydrogen peroxide channeling. Consequently, how to prevent or at least limit this channeling is the key to eliminate the pressure instability of catalyst bed. It was found that adding clapboard to the catalyst bed can depress the pressure instability efficiently.

结果表明催化剂床及催化剂的吸热对过氧化氢分解过程影响很大，对催化剂床进行预热或采用热导率低的材料制造催化剂床等措施，可以降低催化剂床壁面吸热对催化分解过程的影响，提高催化剂床的响应特性和催化分解效率；催化剂床的低频不稳定是催化分解过程与供应系统耦合产生的，催化剂床气体界面的波动过程中，液体过氧化氢穿透催化剂床形成过氧化氢液体通道，过氧化氢液体通道的产生和扩大是催化剂床不稳定的主要原因，也是消除催化剂床不稳定的关键，试验中在催化剂床内加入分流板成功地抑制了催化剂床的低频不稳定。
