查询词典 bulky

The intramolecular hydrogen bonding can extend the ligand planarity and increase the intercalative ability of the complex to DNA. It is concluded that the torsion between the aromatic rings of ligands, due to introduction of the bulky substituent, results in the complexes only to partially or non-classically intercalate into DNA.

结果表明，在吡唑啉化合物的5位引入稠环取代基提高了吡唑啉化合物的熔点；同时，5位取代基的电位性质还影响着化合物的发光行为。

The formation of secondary phase in the non-equilibrium peritectic reaction was observed by precise transmission electron microscopy analysis. The microstructural evolution and phase selection regularities under different solidification velocities were constructed from the laser resolidification experiments. A new phenomenon involving two-phase coupled growth was firstly detected in the rapidly solidified Ti-Al peritectic alloy. The Ti-45Al-2Cr-2Nb alloy with fully lamellar structure ( a 2+ g ) was taken as an object to investigate the possible preparation of bulky metastable g phase materials based on both adjusting the competing nucleation relation and changing the growth kinetics condition.

首先通过过冷合金微观组织分析界定了各包晶合金熔体中各竞争相以初生相出现的过冷度区间；结合高温区的相图计算，从各相形核孕育时间角度揭示了过冷熔体中亚稳相与稳定相的竞争形核关系；通过精细微观组织分析，阐明了远离平衡时包晶反应中次生相的形成机理；在激光重凝快速凝固实验中建立了不同凝固速度下合金的组织与相形成规律，并对包晶合金中两相共生生长行为进行了深入分析；最后选取初生相为 a 的全层片 Ti-45Al-2Cr-2Nb 合金，从调整各相竞争形核关系和改变晶体生长动力学条件两个方面探索了块状亚稳 g 相材料的制备和控制。
