异倍性

In the paper, the orientation behaviors of polyurethane film were investigated by means of infrared dichroism measurement.

采用红外二向色性法对聚四氢呋喃醚二醇/ 4 ，4′-二苯基甲烷二异氰酸酯系聚氨酯薄膜样品的拉伸取向行为进行了研究，结果表明，随着拉伸倍率的增大，CH2 角基团发生取向。

The flow cytometry was used to measure the DNA ploidy type and cell proliferous ratio of NP,BPH and PC.

PC组异倍体率为65.71%；NP组和BPH组均为DNA二倍体。PC组细胞增殖各期比值与BPH组、NP组差异有显著性(P.01)。

Methods DNA aneuploid and TA were detected respectively in 165 cases of malignant pleural effusion and 127 cases of benign dropsy of chest (benign group, including tuberculous,other effusion and transudate of chest) by FCM and TRAPHybELISA.Carcinoembryonic antigen was also detected in the two groups.The difference of DNA aneuploid and TA between these two groups was analyzed.

恶性积液165份、良性积液127份(包括结核性、其他渗出液、漏出液)，应用流式细胞术检测DNA异倍体、端粒末端重复序列扩增—杂交—酶联免疫分析技术检测TA，同时检测临床常用的癌胚抗原，比较各类积液中上述3项指标检测结果的差异。

Thus, the meiotic chromosome cofigurations showed that the tetraploids and hexaploids in C.reticulata allopolyploids, and the appearance of a few tetravalents in some populations might indicatehomology of chromosomes in different genomes to some extent.

根据减数分裂的构型，我们认为，四倍体和六倍体分别为异源四倍体和异源六倍体，少数四价体的存在表明染色体有部分同源性。

A new board shaped ozone generator is proposed to efficiently generate ozone. This paper introduces the generator design based on surface discharge theory in the nonuniform electric field.

臭氧是氧气的同素异形体，与常见的消毒剂氯气相比，臭氧的灭菌速度是氯气的600～3000倍，而且，臭氧的高效杀菌灭毒本领和不留二次污染性历来受到人们的青睐。
