It shows that the model of dissolution equilibrium of DHVR in mixed C solvent obeys the Flory Huggins equation and the solubility parameters of DHVR under ～℃ can be calculated by the equation.
|
|
|
果表明，DHVR与混合C溶剂的溶剂平衡模型遵循Flory－Huggins方程，由此计算得到了DHVR在 ～℃的混合C溶剂中的溶解度参数； |
|
It was also showed that the concentration content and concentration factor of Lanthanum in Closterium lunula under 0 mg/L(La + ) treating were higher than which under mg/L(La + ) treating.

高浓度（0mg／L）处理组的富集量和富集系数，均高于低浓度的（mg／L）处理组 |
|
It acts as a catalytic subunit which interacts with the Fanconi animia core complex to induce the mono-ubiquitinylation of FANCD. The mono-ubiquitinylated FANCD, BCRCA and BCRCA constitute a complex which is concerned with the DNA repair.

另一个则与人的范康尼氏贫血症(Fanconi animia)的发病有关,它作为一个催化亚基与范康尼氏贫血症核心复合物(Fanconi animia core complex)一起使得FANCD单素化,单泛素化后的FANCD将与BCRCA、BCRCA形成复合物参与DNA的修复过程[][]。 |
|
It adopts the relative triggering mode to realise the phase-shifting and quick adjustment of the control-angle α, and makes sure that the maximum time of losing control is less than . ms.

|
在控制算法上，采用相对触发方式，实现控制角α的移相和快速校正，从而保证最大失控时间小于 ． ms。 |
|
It alo included a study on the influence of transgenic paulownia on two agriculturalbacteria: Bacillus thringiensis and Sinohizobium melilot. After half year, the bacteria were collected from soils and quantified.
|
|
|
此外进行了转基因泡桐对苏云金芽孢杆菌Bacillus thringiensis和苜蓿中华根瘤菌Sinohizobium melilot影响的研究，结果表明：半年后，两种供试菌在在半年后两种泡桐植株的根际土壤中的数量均有大幅的减少，但是转基因植株和对照植株在减少的量上没有显著差异。 |
