Cyanide: Any of various salts or esters of hydrogen cyanide containing a CN group, especially the extremely poisonous compounds potassium cyanide and sodium cyanide.

氰化物：一种包含CN基团的氰化氢的盐或酯，特别是剧毒化合物氰化钾和氰化钠。

We studied the 60Coγ-ray radiolysis of thiocyanate aqueous solutions in the presence of free radical scavengers,determination of cyanide of radiated thiocyanate solutions, degradation of cyanide and thiocyanate complicated system and cyanide、thiocyanate and copper cyanide complicated system.

研究了硫氰酸根及其复杂体系60Co源γ射线辐照降解的情况，分别探讨了在自由基清除剂存在下硫氰酸根的降解，硫氰酸根辐照后氰的浓度，氰、硫氰复杂体系和氰、铜氰及硫氰酸根的复杂体系的辐照降解情况。

Cyanide ion is one of the most toxic inorganic anions one can find, but cyanide or hydrogen cyanide are used in many industries.

氰化物为环境中公认的无机剧毒物，对环境的污染尤其是水资源的污染已成为一个严重的问题。

It was found that low hydrogen purity and high moisture content of the hydrogen used for deoxidation was the main cause. Countermeasures such as exhausting 90% of the waste gas from the deoxidation process to hydrogen recompression system to reduce the water content in deoxidation zone, and using hydrogen from PSA unit to replace recycle hydrogen to increase the hydrogen purity, were adopted.

参考UOP公司及其它重整装置的经验，对重整催化剂还原工艺进行了改进，将90％的还原废气排入增压氢系统，可有效降低还原区的水含量；用PSA氢替代循环氢，可进一步提高还原区氢纯度，从而提高还原反应速度，改善再生催化剂的性能，使重整反应的芳烃产率有所提高。

"Cyanide process: or MacArthur-Forrest process, Method of extracting silver and gold from their ore s by dissolving them in a dilute solution of sodium cyanide or potassium cyanide."

氰化法：亦称麦克阿瑟－福莱斯特法，是将含金和银的矿石溶解于氰化钠和氰化钾稀溶液中，以提取金和银的一种方法。

"Cyanide process: or MacArthur-Forrest process, Method of extracting silver and gold from their ores by dissolving them in a dilute solution of sodium cyanide or potassium cyanide."

氰化法：亦称麦克阿瑟－福莱斯特法，是将含金和银的矿石溶解于氰化钠和氰化钾稀溶液中，以提取金和银的一种方法。

"Cyanide process: or MacArthur-Forrest process, Method of extract ing silver and gold from their ores by dissolving them in a dilute solution of sodium cyanide or potassium cyanide."

氰化法：亦称麦克阿瑟－福莱斯特法，是将含金和银的矿石溶解于氰化钠和氰化钾稀溶液中，以提取金和银的一种方法。

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。

Cyanide in water, in tissues of aerial part of plants and in air was analyzed spectrophotometrically. Results from this study indicated less than 10.85% reduction of the applied iron cyanide complex was detected in hydroponic solution in the presence of plants. Little amounts of cyanide were found in all parts of plant tissues, indicating the passage of ferrocyanide through the plants.

结果表明：(1)低浓度实验组52.99mg CN L^(-1水溶液中10.85%的亚铁氰化物被植物吸收，随着浓度的升高吸收到植物体内的亚铁氰化物的比例依次递减，但是统训学分析显示各实验组单位体重的植物吸收亚铁氰化物的量无显著性差异；(2)在植物的各个部位都能检测到微量的亚铁氰化物，表明亚铁氰化物通过植物的蒸腾作用在植物体内的迁移。

It is suggested that TDS can be used as a new method for the analysis of pedogenesis and climatic change.

总之，热处理过程中磁化率的变化能非常灵敏地反映磁性矿物的转化情况，而且，这种转化往往与样品所经历的土壤化作用强度密切相关，因此，TDS可做为分析成土作用强度和古气候变化的一种新方法。

Therefore, in this chapter, I will research into the conflict and contradiction of the paternity. Also, in this novel, the father's behavior of "He who loves well chastises well." is quite suspicious, one of the reasons is that the father thought his son belonged to him. And then, this thesis quoted Lacan's theory to touch upon that someone who has accepted the concept of patriarchal society, he will be influenced for his whole life. That also reveals that human being has no choice sometimes in this society.

因此本章会先就父子关系的冲突与矛盾做深入的探讨，小说中的父亲似有对儿子爱之深责之切的行为，其原因可能在於父亲将儿子视为所有物所致；其次，论文将引用拉冈相关理论，讨论在父权社会中，不论身分为何，只要是已受父权社会观念根深蒂固影响的人物，终生都将受其所苦，此也揭示出人生存於社会上的无奈。
