non-competing groups

Tuning the intermolecular interaction of such kind of tetrapyrrole derivatives can be easily reached by introducing functional groups ( actually additional non-covalent interactions) onto the peripheral positions of porphyrin ring.

所以，调控卟啉类化合物及其衍生物的分子间弱作用可以很容易地通过在卟啉环或其衍生物的外围引入不同的官能团（实际上是通过引入官能团来引入非共价弱作用）来实现。

Better tables, including captions, column groups, and mechanisms to facilitate non-visual rendering.

更好的表格，这些特性包括标题，列分组以及简化非可视化输出的机制等。

In this paper, the solder joints are divided into two groups according to analysis with unit temperature load. Non-critical solder joint was condensed by performing static substructure method.

在本文中，首先根据单位温度加载的分析结果将焊球分为关键焊球与非关键焊球两组，对非关键焊球使用静态子结构法进行静凝聚，然后再进行温度循环分析。

Retrotransposons are a class of mobile genetic elements that are particularly abundant in plant genomes. Retrotransposons can be divided into two major groups: the long terminal repeat ( LTR) and the non-LTR retrotransposons.

植物反转录转座子是植物基因组中一类可移动的遗传元件，可分为LTR反转录转座子和非LTR反转录转座子两类。
