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.
