6.the grain of AZ91D alloy at different pouring temperature can be obviously refined by mechanical vibration, and the refined effort is best at 740 ℃;
机械振动能明显细化不同浇注温度下的消失模AZ91D晶粒,且在740℃温度下细化程度最好;
7.This paper mainly studies the restarting process of the Davidson method,and proposes two new methods : refined block Davidson method and refined block Davidson method with deflation.
本文主要研究了块Davidson方法的重新开始技术，提出了精化块Davidson方法和收缩的精化块Davidson方法。
8.At the second step,using benzene absolute alcohol 〔 V (C-6H-6)∶ V (CH-3CH-2OH)=2∶1〕 as solvent,white needles were obtained. The needles were transformed into refined podophyllotoxin by oven drying for 2 h at 125 ℃. Mass percentage of podophyllotoxin in the refined product was>96% and the total yield was 1 7%.
采用二步结晶法 ,先用苯作溶剂 ,除去绝大部分杂质后 ,再用苯 乙醇〔V(苯 )∶V(乙醇 ) =2∶1〕为溶剂 ,重结晶 ,得白色针状溶剂加合物结晶 (熔点 92～ 93℃ ) ,12 5℃烘干 2h ,脱去溶剂分子后 ,即得精品鬼臼毒素 ,其质量分数 >96 % ,产率为 1 7%
9.The crude phytin is prepared by neutralizing the solution that is aqueous HCI extracts from de - fatted rice bran with CaO/NaOH. The refined phytin is prepared by treating the crude phytin with H2SO4/CaCl2 Finally,the refined phytin is changed to phytie acid by Cationexchange.
脱脂米糠用HCl水溶液浸泡,再用CaO/NaOH中和制得粗菲丁,粗菲丁用H_2SO_4/CaCl_2处理得到精制菲丁,精制菲丁再通过阳离子交换而制得植酸。
10.RESULTS:The color,acid value,peroxide value,unsafonifiable matter and water residue of the refined soybean oil were accorded with the criteria of the refined soybean oil of some foreign pharmacopoeias.
结果 :精制大豆油的色泽、酸价、过氧化值、不皂化物及水分含量均低于国外药典精制大豆油质量标准。
