5.PSS plus AS and CAC group was given 50 mg daily propylene glycol alginate sodium sulfate, 2.5 mg daily alendronate sodium and 50 mg daily complex amino acids chelated calcium capsule.
藻酸双酯钠+阿仑膦酸钠+乐力组予藻酸双酯钠50mg/d、阿仑膦酸钠2.5mg/d和乐力50mg/d灌服。
6.In order to establish a method for determining patulin in apple juice by high performance liquid chromatography (HPLC) which can separate 5-hydroxymethyl-2-furaldehyde (HMF) effectively, the apple juice sample was extracted with ethyl acetate and the extract was cleaned up with sodium carbonate solution and then was dehydrated by anhydrous sodium sulfate.
为了建立能有效地将苹果汁中羟甲基糠醛分离的展青霉素高效液相色谱测定方法,将苹果汁样品用乙酸乙脂提取,提取液经碳酸钠溶液净化,无水硫酸钠脱水,再通过反相色谱柱检测。
7.Implanted B ion in the PyC interphase came into being B4C, and reacted with oxygen and sodium sulfate producing B2O3. B2O3 could barrier the diffusion of O2 and Na2SO4 steam into interphase downwards of 1273K of volatilization temperature of B2O3. Upwards of 1273K, B2O3 will volatilize gradually and lose the protection to the interphase.
