查询词典 specimens

After repeating 5 times, the result shows that the genome DNA can be extracted from the fresh specimens by the methods ,but fail to be extracted from the preserved specimens with the same methods through electrophoresis.

经 5次重复实验，结果表明，用两种方法均能从新鲜标本中获得较完整的DNA ，且DNA得率较高；而对于无水乙醇保存的标本，提取出的DNA用琼脂糖凝胶电泳检测不出DNA条带，说明标本在保存过程中DNA可能发生了变化，致使提取出的DNA量太少或未分离出DNA 。

The results are:(1) The brightness of the specimens will decrease and the chromatism will increase with the prolongation of time of heat treatment. Compared to heat treatment in vacuum, the specimens have more color changes after heat treatment in air, with the same temperature and time of heat treatment.

该研究的结论为：(1)在相同条件下，随着处理时间的延长，试材的明度减小，色差增大；空气介质中热处理和真空中热处理相比，在处理温度和时间相同的情况下，前一种方法处理后的试材材色较深。

The results are:(1) The brightness of the specimens will decrease and the chromatism will increase with the prolongation of time of heat treatment. Compared to heat treatment in vacuum, the specimens have less brightness and more chromatism after being heat treated in air, under the conditions of same temperature and time of heat treatment.

该研究的结论为：①在相同条件下，随着热处理时间延长，木材明度减小，色差增大；空气介质中热处理和真空中热处理相比，在处理温度和时间相同的情况下，前一种方法处理后的木材明度更小，色差更大。

The water-saturated and boiled specimens of China fir are hot pressed with the average compression rate of 50%. Then they are heat treated in a common oven or in a vacuum oven, with the temperatures of treatment of 140,160,180,200,220℃, respectively. Then the brightness, chromatism, infra red spectra of the specimens are measured and discussed.

为了探讨热处理过程中杉木压缩木材的材色变化规律，以及材色和木材化学主成分变化之间的关系，该研究测定了空气介质和真空中热处理杉木压缩木材(热处理温度范围140～220℃，时间范围0～36h)的明度、色差以及红外光谱。
