In this research,the indexes relating to the quality of the fried oil,including the content of the ploymers,acid value,iodine value,saponification value,peroxide value,the content of the diglyceride,oxidation stability,viscosity,were detected.The results showed that with the frying time prolonging,the content of the polymers and viscosity increased greatly,iodine value and saponification value decreased,peroxide value and acid value increased,and the content of unsaturated fatty acid reduced,a little of diglyceride produced.

在食用油煎炸过程中，对油脂品质相关的指标(包括酸值、碘值、皂化值、过氧化值、脂肪酸组成、氧化稳定性、黏度、聚合物的含量以及甘一酯、甘二酯和甘三酯的含量)进行检测，结果表明，随着煎炸时间的延长，煎炸油中的聚合物含量大大升高，黏度增大，有少量甘二酯生成，不饱和脂肪酸含量下降，碘值、皂化值降低，酸值、过氧化值升高。

In addition, ioding was found to be an efficient catalyst for the imino Diels-Alder reaction of N-arylimine and enol ethers and the reaction provided tertrahydroqinolines in good yields. One pot synthesis of tetrahydroqinolines from aldehyde, aniline and enol ethers was also achieved using iodine as the catalyst. The chemical yield of the"one pot"reaction was comparable with that obtained using preformed N-arylimine.

After forming the tooth week bag, usually carried on a medicine processing to the tooth week bag, can place to go into various medicine in the tooth week bag, such as iodine glycerin, compound prescribe iodine liquid or anti-virus medicine, make the tooth kept a higher medicine density inside the bag for week, exterminate a tooth various germ of bag attained to disinfect, eliminate inflammation and refrained from rash action for week of function.

形成了牙周袋后，通常对牙周袋进行药物处理，可在牙周袋内置入各种药物，如碘甘油、复方碘液或抗菌药物，使牙周袋内保持较高的药物浓度，消灭牙周袋的各种细菌，达到杀菌、消炎和收敛的作用。

The total analysis time is 20 s at the rate of 10 kHz for mass spectra recording, and detection limits of 10×10^(-6) and 5×10^(-6) were measured for benzene and methyl iodide respectrvely.

用32cm无场飞行管，测量碘甲烷得到的质谱分辨率可达430。在谱图获得频率10kHz的操作条件下，样品总分析时间20s，得到苯和碘甲烷的检出限分别为10×10^(-6)，5×10^(-6)。

Iodine, however, is not added in the form of a volumetric solution but is produced in an iodide-containing solution by anodic oxidation.

然而，碘不是以滴定溶液的形式加入，而是通过阳极氧化含有碘化物的溶液生成的。

The released I2 could react with the starch to form a blue complex, which had the maximum absorbance at 574 nm. BOD5 in water could be calculated through the amount of dissolved oxygen before and after 5 days determined.
