After it was adjusted with ammonia until the test paper turned purple,in subacid medium of pH 6～7 ammonium acetate buffered solution,bivalent nickel was precipitated quantificationally by dimethylglyoxime.

试样以稀硝酸溶解高氯酸冒烟后，酒石酸掩蔽剂将铁等干扰元素配位掩蔽，以氨水调节至刚果红试纸呈紫色后，在pH6～7的乙酸铵缓冲溶液微酸性介质中，二价镍定量地被丁二酮肟沉淀。

When the temperature gradient and the magnetic field gradient are in the same direction, the heat transfer can be strengthened.

磁场与温度场和浓度场之间的方向协同良好时，能起到强化氨水吸收过程中传热传质的作用。

A new method of removing thiol from RFCC naphtha by liquid-liquid extraction using aqua ammonia was introduced.

提出了一种重油催化裂化汽油氨水液-液脱臭新方法。

After the studies on the fruit of Viburnum sargentii Koehne, it is showed that it has the effect to the cough and it has no toxicity; The active part is the acidity part. Through the GC-MS, we obtain 23 compounds from the volatile oil. By HPLC analytical method, the content of chlorogenic acid is 0.82%.

本文通过对小鼠氨水引咳实验和急性毒性实验，证明了本品的止咳作用，并且没有毒性；在有效部位的筛选中，确定其有效部位为NaOH洗脱部分；在挥发油的成分测定中，共分离出32个峰，鉴定出23个化合物，占挥发油总量的95％以上；在绿原酸的含量测定中，测出其绿原酸含量为0.82％。
