按《中国药典》2005年版二部附录Ⅵ H进行检查里面的H什么意思

因为：W3为“称量瓶+样品”,所以：W3=W1+W2,所以：
(W1+W2-W3) / W2=(W1+W2-（W1+W2）) / W2=0/ W2,这方法、公式有意义么?
W3应该是失水后“称量瓶+样品”的数值,而W1+W2是称量瓶的重量加失水前样品的重量,也就是（W失水前-W失水前) / W失水前.（这里不考虑称量瓶的重量）
W1的恒重值为在105℃~110℃间恒重1小时的称量值.
至于平均值,什么叫“平均值”?不就是几个实验数值之和取平均么?你做三个样品,就把三个数值相加后除以三；你做五个样品,就把五个数值相加后除以五.

维生素E的标准收录在中国药典二部2010年版,908页,你可以仔细翻看标准,好了,现在把含量的测定方法发给你吧!
【含量测定】照气相色谱法（附录V E)测定.
色谱条件与系统适用性试验 用硅酮（OV-17)为固定
液,涂布浓度为2%的填充柱,或用100%二甲基聚硅氧烷为
固定液的毛细管柱；柱温为265°C.理论板数按维生素E峰
计算不低于500(填充柱）或5000(毛细管柱）,维生素E峰与
内标物质峰的分离度应符合要求.
校正因子的测定 取正三十二烷适量,加正己烷溶解并
稀释成每1ml中含1.0mg的溶液,作为内标溶液.另取维生
素E对照品约20mg,精密称定,置棕色具塞瓶中,精密加内标
溶液10ml ,密塞,振摇使溶解,取1〜3微升注入气相色谱仪,计
算校正因子.
测定法 取本品约20mg,精密称定,置棕色具塞瓶中,精
密加内标溶液10ml,密塞,振摇使溶解；取1〜3微升注入气相色
谱仪,测定,计算,即得.

Purpose
Study the superiority between the artificial lamp inspection and mechanical lamp inspection, according to the requirement of injection clarity in Chinese Pharmacopoeia edition 2010 and demand of GMP.
Method
Compared the advantages and disadvantages by these actual operation.
Result
Inspected rate of mechanical lamp inspection higher than artificial lamp inspection, though more damaged bottle and error detection.
Conclusion
In the actual practice artificial lamp inspection has advantages of low cost and low error detection, while mechanical lamp inspection more effective but more requirements and more interference factors. We can ensure the qualified detection by mechanical lamp inspection are definitely fine, but the unqualified products need artificial light inspection for futher ensure.

《中国药典》对盐酸氯丙嗪注射液含量测定,选306nm波长测定的原因是（ ）.A.306nm波长处是其最大吸收波长.

你好,2005版中国药典共有三部,一部为中药制剂标准,二部为化药制剂标准,三部为生物制剂标准,现行的中国药典为2010年版,望采纳!

药理学和药物化学没有专门的国家标准的,药剂学的国家标准也是《中国药典》,简单的说,《中国药典》是药学类学科的通用国家标准啦.

翻译如下,希望采纳：
The comparison of measuring methods for Secobarbital 's content.
Abstract
The content of Secobarbital was measuring by bromimetry in Chinese Pharmacopoeia.but in the practical work, it is often measured by argentimetry,ultraviolet spectrophotometry,
high efficiency liquid spectrometry and acid-base titration,etc. After comparing and summarizing for these methods,it could be measuring by suitable methods according to different demands and needs In the practical application in order to obtain a satisfactory result .

The bromimetry is used in general examination and verification becasue this method's drug specificity is strong. The argentimetry is easy and simply to handle,so it is suitable in usual measuring. The ultraviolet spectrophotometry 's accuracy is better, and it is easier because of the continuously improving of the modern technology. The high efficiency liquid spectrometry is often used in the analysis of trace amounts of drugs in biological sample.etc. because this method is accuracy and sensitive.

Key words:
Secobarbital,content's measuring,comparison of the methods

解题思路：有毒胶囊中重金属“铬”含量严重超标，这里的“铬”不是以单质、分子、原子、离子等形式存在，而是指元素，通常用元素及其所占质量（质量分数）来描述．

有毒胶囊中重金属“铬”含量严重超标，这里的“铬”不是以单质、分子、原子、离子等形式存在，这里所指的“铬”是强调存在的元素，与具体形态无关．
故选B．

点评：
本题考点： 元素的概念．

考点点评： 本题难度不大，主要考查元素与微观粒子及物质的区别，加深对元素概念的理解是正确解答此类试题的关键．
