In the aqueous solution, Cu precipitates with ammonium thiocyanate and tetradecyl benzyl dimethylammonium chloride .

研究发现，在水溶液中Cu与硫氰酸铵、氯化十四烷基二甲基苄基铵形成不溶于水的三元缔合物，在少量氯化钠存在下此三元缔合物沉淀浮于水相上层并与水分成界面清晰的两相，分相过程中Cu被定量浮选。

It is prepared through preparing the materials including alpha-silicon nitride crystal whisker, deionized water as solvent, polyethylene imine as dispersant, PVA as adhesive, propylene glycol as plasticizer and ammonium tetramethyl chloride to regulate pH value; mixing; twice ball milling and post-treatment.

所述浆料的制备方法是：加入α-氮化硅晶须，以去离子水为溶剂，以聚乙烯亚胺为分散剂，聚乙烯醇作为粘结剂，丙二醇作为增塑剂；加入四甲基氯化铵来调节料浆的pH值；制备步骤包括配料、混合、两次球磨及后处理工序。

Results There were four arteries supplying blood to the dorsum of the rat:cephalic artery,thoracodorsal artery,posterior intercostals artery,and deep circumflex iliac artery.

There were 15 pediatric ALL patients, which had received 50 times of chemotherapy with HD-MTX. The records about blood concentration of MTX and clinical conditions for 50 times chemotherapy were divided into two groups. Group I: contained 25 records of stand-risk patients, administering MTX 3.0g/m2; Group II: contained 25 records of mid and high-risk patients, administering 5.0g/m2. Continuous intravenous dripped MTX for 24th in both two groups, while implemented hydrating and alkalizing for 4 days. All patients were rescued 6 times through leucovorin, 15mg/m~2, since 12th after the end of MTX dripping. Then examined the blood concentration of MTX by fluorescence polarization immunoassay approach at 24h, 44h, 68h, at the same time inspected liver function, blood routine examination, the occurrence time and degree of toxicological reactions.

观察15例ALL住院患儿，接受大剂量MTX共50例次，按ALL危险度分2组，低危治疗组接受MTX剂量为3.0g/m2为I组；中高危治疗组接受MTX剂量为5.0g/m2为II组，连续静脉点滴MTX共24小时，同时给予水化碱化治疗，共4天，全部病例均在MTX滴注结束后12小时开始静脉推注四氢叶酸钙(leucovorin，LV)解救，15mg/m2/次，共6次，采用免疫偏振荧光法检测药物滴注24、44、68小时MTX血药浓度，同时检测两组病例的肝功、血常规，观察临床出现MTX毒副反应的时间及程度，观察每个病例毒副反应出现程度与MTX血药浓度关系，两组毒副反应程度比较，进行统计学分析。
