In this thesis, we used this principle coupled with flow injection solid phase reactor on-line oxidation, solid phase extract and dialysis separation technology to establish the on-line oxidizing fluorometric method for determination thioridazine hydrochloride and methotrexate in table and plasma samples, respectively.

第二章：研究报告一、流动注射在线氧化荧光法盐酸硫利达嗪分析体系研究流动注射在线氧化荧光法测定药物中盐酸硫利达嗪含量本方法根据盐酸硫利达嗪的氧化产物具有强荧光这一性质，在磷酸介质中利用二氧化铅固相反应器在线氧化盐酸硫利达嗪并通过乙醇对其的增敏作用，建立了流动注射在线氧化荧光法测定盐酸硫利达嗪含量的新方法。

I also use a medicine called Trental or Pentoxifylline as a phosphodiesterase inhibitor.

我也使用磷酸二酯酶抑制剂如巡能泰或己酮可可碱进行治疗。

Diethylphosphite was prepared from ethanol and phosphorus trichloride at mole ratio of 3.3:1 with the droping temperature at 5-10℃, and reacted under room temperature.

以无水乙醇和三氯化磷为3.3：1的投料量，5～10℃下滴加，室温下反应，制备亚磷酸二乙酯。

Triphenyl phosphite provided prominent stabilization only when used in combination with other stabilizers. Good results have been obtained for both polyether-urethane and nitrate esters when using 2,6-di-t-butyl-4-methyl-phenol as stabilizer.

亚磷酸三苯酯单独使用时效果较差，但与其它种类的稳定剂混合使用能得到较好的效果。2，6-二叔丁基-4-甲基酚对硝酸酯和聚氨酯粘结剂均具有良好的稳定作用。

It's quite suitable to be used in the analysis of related substances of cytidine disodium triphosphate.
