- And it was found that the effect of strengthening laser energy is similar to that of prolonging the excitation time, and the photochromism process of MR strongly depends on steric hindrance around azobenzene molecule.
结果表明：增大激发光的光强与延长激发时间对促进MR分子光致异构具有等效作用，而且MR分子的光致异构过程对周围的空间位阻有很强的依赖性； - The Effect of Steric Hindrance on the Photophysical Behavior of Substituted Styryl Pyrazine Derivatives
结构受阻对取代苯乙烯基吡嗪光物理行为的影响 - Results the particles may have higher electrostatic effect by adjusting the pH value of the medium and have steric hindrance effect by adding the surfactants on the previous condition, which prevent the particles from agglomeration.
结果：调节介质的pH值，使颗粒间处于较高的静电效应，在此条件下加入表面活性剂，使颗粒间又具有空间位阻稳定效应，空间位阻稳定效应可阻止颗粒间的团聚。 - The effect of steric hindrance and electron on aromatic aldehydes reduced by BER
BER还原芳醛的位阻效应和电子效应 - HTMA cured with epoxy resin gently and slowly, owing to the synergistic effect of steric hindrance effect and stereo-electronic effect.
空间位阻效应及电子效应的协同作用使HTMA与环氧树脂的固化反应速度降低，固化过程中放热量小，放热平缓。 - The effect of steric hindrance in the Stephen reaction and the syntheses of some substituted benzaldehydes
关于空间阻碍在Stephen反应中所起的作用及一些芳香醛的合成 - On the other hand, the methyl substitution would reduce the polarity of CD cavity. Effect of number and position of methyl substituents on the steric hindrance was important.
与β-CD相比，甲基的引入一方面可以增加空间位阻，另一方面降低了环糊精空腔的极性，取代基的个数和位置是影响空间位阻的重要因素。 - The effect of steric hindrance on the performance of dechroming was obvious and increasing temperature and associative hydrochloric acid could alleviate the effect degree. The dechroming ability and destructiveness on the stability of collagen of acid groups were bigger than H+.
