The thermal property of the dye is another important factor to be optical recordingmedium. It needs a suitable high decomposition temperature with a fast weightreduction process, and this will make the information recording bits clearly andsmoothly, then the byte error rate will decrease during write-in and read-out.

染料的热学性能是作为光记录介质的另一个重要参数，它要求染料具有适当高的分解温度，同时伴随一个迅速的失重过程，从而使记录点边缘明显而光滑，在信息的读写过程中误码率小。

According to the results of differential thermal analysis and thermogravimetry of a zein film, its glass transition temPerature is 171℃ and the decomposition temperature is 262℃.

醇溶玉米蛋白膜的差热分析结果表明其玻璃化转变温度为171℃，热分解温度为262℃。根据热重分析，温度为81℃时，失重率为2.3％，主要是乙醇及水分子的蒸发。262～355℃为产品急剧分解阶段，与差热分析结果相吻合。

Third, with the increase of the particles size, the curve of the TG moves to the hightemperature zone, the initiatory temperature of pyrolysis augment but the abeyant temperature decrease, the main pyrolysis temperature zone become narrower, the total weight loss decreased.

第四，随煤化程度的升高，TG曲线向高温区移动，煤的热解初温升高、终温降低，主要热解温度区间变窄；_和T_增大，最终失重率下降。

ABSTRACT Living in a weightless environment often produces some adaptational and pathophysiological changes refered to as adverse effects.

Thirteen undergraduates(7 male and 6 female)participated in manual performance evaluation studying with barehand and with the simulated spacesuit glove through strength,fatigue,tactile perception,range of motion and dexterity 5 studying indices(28 testing indices),and the 28 testing indices were optimized by using statistics and knowledge of anthroposomatology.

航天员在舱外的作业任务种类繁多，又兼有太空失重和超高低温等恶劣因素存在[1，2]，这些都给舱外航天服手套的手动作业工效评价提出了较高的要求。O′Hara等[3~7]结合空间飞行部分情况，在地面上对手动作业工效评价的力量、疲劳、活动范围、触觉感知、灵活性5项工效指标开展了较全

In this paper migration theory and techniques related to the high-energy TEGN gun propellant are presented, and some methods determining the migration of RDX are analyzed and compared. As a result, chemical and thermal analyses are employed associatively to test the content of RDX in different position of TEGN gun propellant stored different period. The antimigration capability of TEGN gun propellant making use of two different granularity of RDX is also been studied.
