The test results showed that under low ambient temperature and aphotic storage conditions jet fuel exhibited good color stability.Oxidation reactions,such as photo-catalyzed oxidation and radical oxidation,were the main reaction mechanism of color degradation,and copper played an important role in catalyzing the oxidation reactions.Under static thermal stability testing condi...

试验结果表明，喷气燃料在较低温度、无光储存条件下具有很好的颜色安定性；氧化反应是导致喷气燃料颜色变深的主要反应机理；静态热安定性试验条件下，喷气燃料的颜色随氧化时间呈相对稳定的加深趋势；氧化铝吸附脱除了喷气燃料中的一些原有氧化抑制剂，使喷气燃料在较高温度、有氧条件下易于发生氧化反应；铜在喷气燃料氧化变色反应过程中具有明显的催化作用。

The temperature of cold injury was abo ut 0 ℃ to 15℃,While hot injury would appear when temperature got to 36℃.These ind icat ors were varied in different species,and the greatest difference was the temper ature of cold injury.Growth would be poor in summer under full illumination,whi le part shading was beneficial.The best condition was 70 percentage of sh ading for Araceae and 50 percentage of shading for Agavaceae.The need for soil moistu re was strict.Most of species would grow normally in 65 to 85 percentage of soil m o isture.The characters responsed to illumination,temperature and soil moisture w e re consistent with their original ecologic environment.

其最 适生长温度在16-35℃，除酒瓶兰外，低于10℃时均表现生长停滞状态；寒害温度差异很大，天南星科为0-15℃，龙舌兰科为0-10℃，大多数植物在36℃会产生热害；光照对其影响较大，夏季这两科植物在全光照下长势差而在一定荫蔽的条件下有利生长，最佳荫蔽度天南星科为75％，龙舌兰科为50％；这两科植物对土壤中的水分含量要求较高，大多在土壤含水量70％以上才能正常生长，这些光、温、湿的反应特性与其起源地湿热和荫蔽的生态环境相吻合。

The quality of chlorophyll of wild Aralia elata are unstable to light,heat and acid medium,and in daylight,the decomposing speed of chlorophyll can rise when the time was pro-longed or the temperature was raised.It can be concluded that chlorophyll is easy to compose,while it is ...

叶绿素对光、热、酸性介质均不稳定，易产生降解现象；在散射光环境中，降解速度随时间延长和温度升高而加快；在pH值6～7时的中性条件下最稳定，在pH值3～4的酸性条件下，叶绿素易降解。

Using Fe2(SO4)3 and Ti(SO4)2 as raw materials, Nano- Fe2O3-TiO2 photocatalyst was prepared by an ethyl-assisted hydrothermal method at low temperature to degrade auramine in the three-phase photocatalytic reactor.

以Fe2(SO4)3和Ti(SO4)2为原料，采用乙醇助水热法，在较低的温度下制备了Fe2O3-TiO2复合光催化剂，并用X射线衍射、紫外可见漫反射光谱对其进行了表征。

In the last episode of Bedazzle Kitchen, AIDS concern and Queen Collection will bring more understanding to Gonorrhoea, our two hostess show off their hot red costumes. Making the hottest cooking show even hotter, watch out for the hot plate!

Coco and Karolina 与「关怀爱滋」在最后一集的妖女厨房会带大家认识淋病 Gonorrhoea — Coco与两个妖女穿上火红战衣，使出浑身解数，把节目原本一直处於高潮的状况一再往上推，小心热爆萤光幕！

The alkyl groups have little effect on photophysical properties and oxidation potentials, but have biggish effect to thermal properties.

分子中烷基链的长短对化合物的光物理性质和电化学性质影响很小，但对化合物的热稳定性影响较大。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
