Angular cheilitis, cheilitis, glossitis and Xiang Yin Yan is caused by a lack of vitamin B2, vitamin B2, also known as riboflavin, in the animal food with a high level, liver, kidney, heart, especially the rich, milk and eggs also many; in the plant food content of less content of green leafy vegetables and beans a little more, some slightly more vegetables and pulses content, some wild plants such as Artemisia annua, wild amaranth, etc.

口角炎、唇炎、舌炎和阴襄炎是缺乏维生素B2所致，维生素B2也叫核黄素，在动物性食物中含量较高、肝、肾、心尤为丰富，奶类、蛋类也不少；在植物性食物中含量较少，绿叶蔬菜和豆类含量稍多，有些野菜和豆类含量稍多，有些野菜如青蒿、野苋菜等含量较高。

结果表明Eu2 4Phen2 是一种同时具有空穴和电子传输能力的红色电致发光材料。

In recent years, electrogenerated chemiluminescence has become an important and valuable detection method in analytical chemistry.

近年来，电致化学发光在化学分析领域已经成为一种重要的分析检测方法。ECL是一种由电化学反应所产生的发光现象。

The resul,of DTA indicates that the DTA curve of Hongshuihe chert is very similar to that of standard quartz,but the DTA curve of Jingnan chert is distinct from those,i.e.there is no valley of transition heat effect at 573℃...

这种差异性的存在是由于两者内部α-石英颗粒的粒度、双晶发育程度以及燧石本身的致密度不同所造成。

The results of our research showed that the chinaberry seed oil, two emulsion formulations of crude toosendanin, Margosan-O, azadirachtin, AZT(NR-2), AZAL-S, petrolem ether extract of the leaf of Tagetes erecta, methyl extract of the root of Tagetes erecta, methyl extract of the whole plant of Bidens pilosa, the oil of Ageratum conyazoides and polygodial had potent toxicity to the larvae of Anopheles sinensis, Culex quinquefasciatus and Aedes albopitus.

中华按蚊Anopheles sinensis、致倦库蚊Culex quinquefa-sciatus和白纹伊蚊Aedes albopictus都是我国重要的传病蚊种。本研究首次证实下列植物的提取物对上述三种蚊虫有毒杀作用：(1)苦楝：苦楝油；(2)川楝：川楝素乳剂、蔬果净；(3)印楝：Margosan-O、印楝素、AZT(NR-2)、AZAL-S；(4)万寿菊：叶石油醚提取物、根甲醇提取物；(5)三叶鬼针草：整株植物甲醇提取物；(6)百花草：精油；(7)水蓼：Polygodial。

the model of chloasma in female mice can be induced by the administration of pyogesterone.

黄体酮攻击雌性小鼠所致的黄褐斑动物实验模型获得成功。

Chlordane is one of the persistent organic pollutants which were decided to be controlled globally first by the UNEP due to its physical and chemical stability, recalcitrant degradation under natural conditions and tending to accumulate in organisms. It had been proved that Chlordane may cause cancer, malformation and mutation, so research of elimination of Chlordane in the environments is of great significance to the health and sustainable development of humankind. Chlordane was the research object in this paper.

氯丹是联合国环境规划署发布的全球首批优先治理的持久性有机污染物之一，氯丹物理化学性质稳定，难于自然降解，易于在生物体内富集并对生物体具有致癌、致畸、致突变等作用，氯丹环境清除技术的研究对保证人类健康和社会可持续发展具有重要意义。

If the laser is in ultraviolet-visible wave, photons activate choicely electron energy level or destroy weak bond of compound molecule, and result in chemistry reaction, which is photo leading decomposition mechanism, if the laser is in infrared wave, the chemistry reaction mainly is heat decomposition mechanism.

如果激光是可见紫外波段，光量子能量有利于选择性地激发分子的电子能级，或破坏化合物中弱键而诱导化学反应发生，化合物属于光致分解机理、引发弱键断裂机理；如果激光是红外波段，化合物表现的则是热分解机理。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。
