Starting from 3-benzoyl-5-formyl-indolizine, 3-benzoyl-5-(2'2'-diacetylethenyl)-indolizines and analogs were obtained by the 〓mediated aldol condensation or Wittig reaction. These compounds,promoted by low-valent titanium, gave highly functionlizedcycl[3,2,2]azine derivatives. The coupling reaction proceeded betweenthe carbonyl group and the carbon-carbon double bond, a rare example inMcMurry reaction.

我们以3-苯甲酰基-5-甲酰基中氮茚为原料，通过三碘化钐促进的aldol反应和Wittig反应制备了3-羰基-5-羰基乙烯基中氮茚，随后经低价钛还原偶联，没有生成正常的分子内羰基-羰基偶联产物，而是得到反常的羰基与α，β-不饱羰基的双键偶联产物，较高收率地得到了含多官能团的CycI[3，2，2]azine衍生物。

In chapter 4 an abnormal reaction that the nitro group of 1-aryl-2-nitroethenescan be easily replaced by the organic moity of FG-RZnI using Ni〓 and tertiaryamine as catalyst was first given. The experimental results show that in the presenceof catalytic amount of Ni〓 and tertiary amines, the reaction of FG-RZnI andl-aryl-2-nitroethenes give the substitution products l-aryl-l-alkene, instead ofMichael addition products.

通过实验发现，在催化量的Ni〓及叔胺催化下， l-硝基-2-芳基乙烯与烷基碘化锌并不进行Michael加成反应，而是发生1-硝基-2-芳基乙烯中硝基被取代的反应，生成了高产率的1-芳基-l-烯烃，由于此反应的原料易得、反应条件温和、产物的产率高，因而是合成l-芳基-1-烯烃的有效方法。

A modified analysis method based on the determination of ozone—indigo disulphonate spectrophotometer(GB/T 15437-1995) in gas phase has been developed to detect the concentration of ozone in liquid phase. An analytical condition of λmax=612～615 nm,ε=20 000 L/, pH 2 is obtained by the titration of indigo disulphonate. Compared with potassium iodide method,it shows a higher precision and accuracy,CV＜3.0%. The results also prove that blank experiment will bring about 5.0%systematic error.

在气相臭氧浓度的靛蓝二磺酸钠分光光度法(GB/T15437-1995)基础上提出了液相臭氧浓度的测定方法，采用靛蓝二磺酸钠标准曲线法代替采用易分解的臭氧标准曲线法，得出测定条件λmax=612～615 nm、ε=20 000 L/、pH为2，通过碘量法比较实验，说明新的测定方法具有较高的精度和准确度，相对标准偏差小于3.0%；比较结果表明忽略空白实验将引入5.0%的系统误差。

For a dye regenerated system composed of eosin ethyl ester iodonium salt (EOEtIPh2) triethylamine, the efficiency of sensitization is 4 times higher than of single system EOEtIPh2, at mean time the number of active radicals is also multiplicated and thus this system is of importance in practical application.

由乙基曙红碘翁盐/三乙胺组成的染料再生体系的染料敏化效率比单一体系高4倍左右，同时使活性自由基的数量增殖，这种体系在实际应用方面具有重要意义。

Thyroid gland is located in cervical in front, Adam's apple lower part, tracheal two side, it is the endocrine organ with main human body, assume human body to absorb with memory iodine, synthesize and secrete the function of thyroid element, include estrogen and progestational hormone inside female hormone, participated in the happening of thyroid cancer, development probably, level of the estrogen inside body is higher, make thyroid cancer more possibly happen, 20-40 year old the female is in life exuberant period, level of the hormone inside body is lifetime in most

甲状腺位于颈部前面、喉结下方、气管两侧，是人体重要的内分泌器官，承担人体摄取和存储碘，合成和分泌甲状腺素的功能，包括雌激素和孕激素在内的女性激素，很可能参和了甲状腺癌的发生、发展，体内雌激素水平越高，越可能促使甲状腺癌发生，20-40岁女性处于生命旺盛期，体内激素水平是一生中最

The substituents on 2 and 4 position of furan ring were derived from the propargylic part of homopropargylic alcohol, and the substituent on 5 position of furan ring was derived from the

其呋喃环上2号及4号位置的取代基乃源自於高炔丙基醇之炔丙基，5号位置的取代基乃源自於醇之偕位，故藉此方法合成之碘化呋喃化合物具有高度的位向选择性。

METHODS The residual concentrations of sodium formaldehyde sulfoxylate in the solutions were determined by iodimetry, the datas were fitted by linear regressions and then ...

在高精度电热恒温箱中在不断通入空气或医用纯氧的情况下，采用碘量法测定甲醛合次硫酸氢钠在水溶液中不同时刻的浓度，作出降解曲线，将测得的数据进行降解动力学方程的拟合并获得动力学参数，并计算反应速率常数。

It contains rich mineral elements such as iodine, potassium, calcium, manganese, ferrum and zinc, and also contains rich vitamins, algae gum acid, mannitol, etc, which the land plant can't provide.

Tea seed oil is rich in polyphenols, such as vitamin E and carotene, unsaturated fatty acids of which more than 85%, iodine value 112, vitamin E content than other edible vegetable oils high; the nature of tea-seed oil stability, sealed storage 1 years after the changes in physical and chemical properties of small, tea-seed oil is therefore easier to store than other vegetable oils; tea seed oil and other edible vegetable oils can be used as cooked dishes or cold dishes, has a unique fragrance.

茶籽油富含茶多酚、维生素E和胡萝卜素等，其中的不饱和脂肪酸超过85％，碘值为112，维生素E的含量均比其他食用植物油高；茶籽油性质稳定，密封储藏一年后理化性质变化很小，因此茶籽油比其他植物油容易储存；茶籽油可以和其他食用植物油一样用来炒菜、凉拌菜等，具有独特的茶香。
