在分子树上，它是处于菝葜属内基部的一个类群，与其它类群(包括部分单伞花序的种及大部分圆锥花序的种)是平行起源的。

The result from phylogenetic trees created respectively by MP, NJ and UPGMA indicates that Bryaceae and Bryum are not monophyletic. The definition of some groups of Bryaceae and Bryum is doubtful in traditional classification based on morphological data. The analyses approves that Pohlia is more closely related to Mniaceae than Bryaceae, which supports placement of Pohlia in Mniaceae from Bryaceae based on DNA sequence data.

系统发育分析的结果显示：丝瓜藓属Pohlia更接近于提灯藓科Mniaceae而远离真藓科Bryaceae的类群，支持Cox等分子序列证据将丝瓜藓属Pohlia放在提灯藓科Mniaceae的安排；大叶藓属Rhodobryum与真藓属Bryum作为姊妹群存在，不支持Ochi将其作为真藓属Bryum内一个亚属的安排。

The mechanism in which trehalose is produced from dextrin or starch hydrolyzate by endocellular enzymes of bacterium D-97 can be elucidated by high performance liquid chromatography with differential refraction detection basically, including the effect of the different carbon sources on the endocellular trehalose-producing enzymes in bacterium D-97 and the possibility or ability of the endocellular enzymes to produce trehalose using maltooligosaccharides of different chain lengths.

通过高效液相色谱/示差折光检测系统分析可获得细菌D-97利用糊精或淀粉水解物合成海藻糖的基本生物学信息，包括微生物培养碳源对细菌D-97胞内海藻糖合成酶系的影响以及该酶系利用不同种类或不同分子链长度的麦芽寡糖合成海藻糖的能力及作用过程。

The affinity among hybridizable species can also be speculated by the extent of homology of their repetitive DNA.

高等植物DNA的很大部分是由重复顺序所构成，本文讨论了检测亲本及子代基因组内重复顺序的异同程度作为远缘杂交的分子水平指标是简便可行的。

The motor molecule forms bipolar thick filaments that interdigitate with thinner actin filaments in the saromere, forming the basic contractile unit of muscle.

在所有的分子马达中，关于肌球蛋白的研究最多。肌球蛋白是肌肉收缩的关键成份，由它们形成的双极粗丝在肌节内同肌动蛋白细丝交叉对插，构成一个收缩单元。

The results of DPBMN in n-hexane solution show that there are two non-radiative processes occurring in the local excited state. The decay time constants of ~4 ps and ~ 220 ps are due to vibration relaxation and intersystem crossing processes respectively.

实验结果显示DPBMN分子在非极性溶剂中的区域性激发态(local excited state，LE state)有两个非辐射缓解的过程发生，首先为发生在LE能阶的振动缓解(~ 4 ps)，之后为系统内转换的过程(~ 220 ps)。

Ruthenium-modified solid catalyst Ru-Co2-CeO2 was applied to the lactonization of diols in the presence of molecular oxygen and achieved highly efficient catalytic performance.

OBJECTIVE ①To compare the sequences of the ribosomal rDNA-ITS2, 28S-D3 and mitochondrial mtDNA-COII in the different origins of Anopheles minimus for detecting the intra-and inter-specific variation of the sibling species of the Minimus Complex;②To reconstruct phylogenetic trees of the Minimus Complex and Myzomyia Series for determining the position of An.

目的 ①比较微小按蚊核糖体rDNA-ITS2、28S-D3基因和线粒体mtDNA-COII基因的序列差异，阐明微小按蚊复合体亲缘种种间和种内变异；②根据基因变异重建微小按蚊复合体及迈蚊系成员的种系发生关系，以确立微小按蚊亲缘种变异的种系地位；③建立微小按蚊复合体亲缘种A和C的分子鉴别方法。

The increases in calcium channels α2/δ1 subunit, GABA〓 receptors α5 subunit, sodium channels and nACh receptors in both DRG and spinal cord indicate their potential roles in the development of new target of analgesia drug.

本研究发现的一些在外周神经损伤后DRG和脊髓背角内都上调的分子，如钙通道α2／δ1亚基、GABA〓Rα5亚基、若干钠通道亚基和nACh R亚基，为寻找新的镇痛药物靶点提供了一定的线索。

This paper indicatesthat the Triticum-Agropyron octaploid species and the alien substitute line containAgropyron DNA sequence in different proportion. This result is consistent with thecytological and genetic analysis.

高等植物DNA 的很大部分是由重复顺序所构成，本文讨论了检测亲本及子代基因组内重复顺序的异同程度作为远缘杂交的分子水平指标是简便可行的。
