WAXD study betokened that both too fast and too slow heating rate go against the formation of ordered aggregation structures in the film; while moderate heating rate made imidization temperature, solvent evaporation speed and chain mobility cooperate well and facilitated chains arrange into regular crystalline structure.

WAXD的研究表明：升温速率过快或者过慢都不利于薄膜聚集态有序结构的形成。

More assimilation products were stored in sheathes than those in leaves. 2After rewaterring, net photosynthetic rate and evaporation rate came back quickly, especially D3 and D6 groups whose two photosynthetic indexes were higher than that of control group and then droped back to normal in serveral days.

同化产物在叶片中的含量高于茎鞘，但叶片中的氮素含量低于茎鞘。2恢复灌溉后，受到胁迫的处理组的光合速率、蒸腾速率都迅速升高，干旱3 d和6 d的处理组光合水平超过对照，然后又有所下降，水分利用效率因为蒸腾速率的骤然升高而降低，之后有所恢复。

The factors which affect the rate of evaporation in enclosed LNG storage tank are various, and they mainly are the initial filling rate, the ambient temperature , the insulation structure (effective thermal conductivity ), the initial pressure within the tank, the tank pressure of work , the amount of nitrogen in LNG, the tank volume size and so on.

影响密闭LNG储罐蒸发率的因素是多方面的，主要有储罐的初始充满率、环境温度、储罐保温结构、储罐内的初始压力、储罐的工作压力大小、LNG中含氮量的多少、储罐的容积大小等。

Because the fish drying Shrinkage small Shrinkage crack surfaces, more in Water, so the bibulous rate of early (see figure 4) soon, absorbing ability, 1.2 m in bibulous rate (Water absorption Measurement can reach 1 36), In the early EHD water are slower, bibulous rate in 30 m in later, when the water absorption speed enough time to also can achieve higher bibulous rate and natural drying EHD with dry bibulous rate basic same, in addition, natural drying and EHD dry fish good water resistance, 120 m in water can still keep complete shape after drying fish, but by 120 m in pieces after absorbing began.

由于热风干燥鱼的收缩率较小、表面有较多缝隙，所以在吸水初期的吸水速度很快(见图4)，吸水能力很强， 120 m in 吸水率可达到1。 36； EHD在吸水初期的吸水速度均较慢，在30 m in以后吸水速度加快，当吸水时间足够时也能达到较高的吸水率，自然干燥与EHD干燥的吸水率基本相同，另外，自然干燥和EHD干燥鱼的耐水性好， 120 m in 吸水后仍能保持完整形状，而热风干燥鱼经120 m in 吸水后即开始溃散。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.
