Results After many times oral administration of Jiangtangning capsules(40～600mg/kg),the blood glucose of hyperglycemic mice,rats and rabbits induced by adrenaline,glucose,streptozotocin and alloxan was decreased obviously,and had significant dose-effect relationship,the symptoms of polydipsa,polyphagia and polyuria were improved for alloxan-induced hyperglycemic mice and rats,meanwhile the release of insulin in alloxan-induced hyperglycemic mice serum was promoted,but having no apparent influence on the normal blood glucose of mice.

结果 在40～600mg/kg剂量下，多次灌服降糖宁胶囊对肾上腺素、葡萄糖、链脲佐菌素和四氧嘧啶引起的小鼠和大鼠以及家兔高血糖均有明显的降低作用，且有明显的量效关系，还可明显改善四氧嘧啶性高血糖小鼠和大鼠多饮、多食、多尿等三多症状，并可促进四氧嘧啶性高血糖小鼠血清中胰岛素的释放。但对小鼠正常血糖却无明显影响。

It means that the athletes live in the plateau or man-made hypoxic surroundings, so as to enhance the organisms hypoxic preadaptation and improve the anti-anoxia ability, while they train in the plain or lower plateau to achieve effective training load.

高住低训训练法就是让运动员居住在高原或人工低氧环境中，增强机体低氧预适应，提高机体抗低氧能力，而训练在平原或较低高原的地方以达到有效训练负荷的一种训练方法。

Thereafter, some research work about the effect of additive percentage of pH value buffer solution and oxygen concentration in flue gas on this system of flue gas desulfurization with pyrolusite pulp in a single JBR was carried out, and it was illustrated that the optimized additive percentage of pH value buffer was 30% and 10% when oxygen concentration in flue gas is 21% and 7% respectively.

针对这一问题，通过实验在JBR反应器中考察了pH值缓冲剂添加比例和烟气氧含量对软锰矿浆烟气脱硫体系的影响，确定烟气氧含量为21%时pH值缓冲剂的最佳添加比例为30%，烟气氧含量为7%时pH缓冲剂的最佳添加比例为10%。

Adding single oxygen quencher and superoxide anion quencher could increase the stabilities and single oxygen was the main reason for photooxidation.

加入单线态氧猝灭剂和超氧负离子猝灭剂均能提高染料的光稳定性，但单线态氧猝灭剂的作用更为明显。

Benzyloxy benzoyldimethylsulfoxide was prepared by the reaction of ethyl 4-benzyloxybenzoate and dimethyl sulfoxide in the presence of sodium hydride, followed by Pummerer reaction with concentrated hydrochloric acid to afford eo-hydroxy-co-thio-methyl-(4/-benzyloxy) acetophenone, which reacted with urea, thiosemicarbazide, semicarbazide hydrochloride and o-phenylenediamine to give imidazolidine-2,4-dione, l,2,4-triazine-3- one and quinoxaline derivatives, respectively.

本文用4-苄氧基苯甲酸乙酯和二甲亚砜为原料，在氢化钠存在下反应，合成了(4′-苄氧基)-苯甲酰基-二甲亚砜。研究了该亚砜在浓盐酸的存在下发生的Pummerer重排反应，用重排产物ω-羟基-ω-甲硫基-(4′-苄氧基)-苯乙酮分别与尿素、氨基脲、氨基硫脲和邻苯二胺反应合成了2，4-咪唑啉-二酮、1，2，4-三嗪-3-酮、喹喔啉等含氮杂环化合物。

The differences of these catalysts reactivity were related to their structures and the activity of lattice oxygen.

这一方面是因为氢的引入使表面的氧物种发生了变化，形成了活性更高的氧物种，另一方面是因为氢的引入加速了氧分子向晶格氧转化。
