DHCC Constance in the chemistry belongs to the onlighted Cyclopentanoperhydrophenanthrene when it reacted together with the acid Constance it could transform into the fluorescence phenol.we did the flouric determination for the DHCC, in which treated by the ethanol-sulfuric acid or acetic anhydride-methylene chloride-sulfuric acid, acquired standard curve in the 0-40μg/ml presented the liner relet...

DHCC类物质在化学上属于不发光的环戎烷多氢菲类，但与酸性物质一起反应时，可转化为产生荧光的酚类。用乙醇硫—酸或乙酸酐—二氯甲烷—硫酸处理后的DHCC进行荧光检测，获得标准曲线0—40μg/ml范围内呈线性关系，检出的最高灵敏度可达300ng/ml。该方法可用于分离后的DHCC及单一种DHCC代谢物的定性及定量分析。

The study suggested that the optimal method not only enhanced the affinity and the maximum reaction velocity of α-amylase with its substrate, but also improved the accuracy and the sensitivity on the activity of α-amylase from M. separata larvae in assays, whereas it was not the optimal method for determining the activity of α-amylase from T. molitor, C. pipiens pollens and M. domestica larvae.

结果说明，在该优化体系下，粘虫α-淀粉酶与底物的亲和力增强，最大反应速度增大，测定酶活性的准确性和灵敏度显著提高；同时该优化体系也可作为测定德国小蠊α-淀粉酶活性的优化方法，但不适合作为黄粉虫、淡色库蚊和家蝇α-淀粉酶的最优化测定方法。

In order to adapt the vegetables variety many, the content low and so on the characteristic, this article studied in the atomic fluorescence spectrographic methods determination vegetables the cadmium method, the result has been satisfied.

就是下面这段：近年来已发表了许多测定镉的论文，由于测定原理不同，灵敏度也各不相同。为了适应蔬菜品种多，含量低等特点，本文研究了原子荧光光谱法测定蔬菜中镉的方法，结果满意。

The wavelength as 284 nm. The results shoed that the method is simple, rapid and sensitive. The byproducts were identified as sulphonyl products In HPLC-MS/MS.
