Objective To establish a molecular method for differentiation of two sibling species, Anopheles minimus A and An. minimus C, of Minimus Complex: polymerase chain reaction-restriction fragment length polymorphism analysis ( PCR-RFLP). 目的建立微小按蚊复合体不同亲缘种A和C的分子鉴别方法&PCR产物酶切片段长度多态性分析(PCRRFLP)。
The results showed: ( 1) All of these compounds revealed molecular ions and their relative abundances seemed to decrease with increasing chain length of R. 结果表明:1.这些化合物都显示分子离子峰,它们的相对丰度似有随R链的增长而减弱的趋势;
The conformation of Ap is related to molecular weight, branched degree and external chain length. 支链淀粉的构象与其分子量、分支度、外链长和淀粉浓度有关。
The influence of the molecular conjugated chain length and the electron-donating group on βμ was examined. 考察了分子共轭链长、给电子基团对βμ的影响。
When the different molecular weight PVP with different chain length as co-template was applied, the different mesoporous materials were obtain. 选择不同分子量的具有不同链长的PVP聚合物为助模板剂制备得到不同大小的空心球介孔材料。
The results of the variation of number-averaged molecular weight during polymerization and the chain length distribution after polymerization show that our model can closely simulate the polymerization process of real experiment. 聚合反应的数均分子量和链长分布都显示此模型能够反映真实的实验结果。
