Also the disomy of autosome is a little higher than gonosome, but there was no significant statistical difference among these values. In diploidy, as the frequencies ranged from 0.035% to 0.083%, heterogeneity was also not obvious.
同时在实验中观察到二体率比二倍率要高的情况,这可能意味着在精子形成的减数分裂过程中,二体更易形成。

The result suggested that different genomes had different genetic speed or stability during evolution.3 The similarities co-efficiency between wild emmer and hexaploid synthetic was higher than that between wild emmer and common wheat. So that crossing among species is not a simple combination of genomes, but involve introgression of chromosomes, and the evolution made by this action was bigger than that made by environment.4 According to the results of salt tolerance identification, the salt tolerance of wild emmer is lower than that of common wheat in the whole.
野生二粒小麦与普通小麦之间的遗传相似系数稍高于野生二粒小麦与其与节节麦合成的双二倍体的遗传相似系数,说明物种之间的杂交并不仅仅是染色体组简单的合并,其中包括复杂的染色体组本身的一些特性以及染色体之间的互渗且这种作用远大于环境作用所引起的变化。

The diameter of secondary pore is 2.64nm, which is twice of the diameter of supercage, therefore we suggested that secondary pore was formed by connecting two adjacent supercages resulted from breakdown of the sodalite between them.
我们以〓Xe NMR方法,首次得到超稳Y型沸石中二次孔的大小为264nm,该直径约为超笼直径的二倍,因此我们认为二次孔的形成是方钠石笼被破坏后,两个相邻超笼相连的结果。

In shoaling process, the main peak frequency of broken wave spectra moves to lower frequency. With decreasing relative water depth, both the ratios of wave spectral energy at twice and triple peak frequency to main peak frequency increase. and when the value of the nonlinear parameter increases, both the ratios increase, too. The Stokes third order wave theory has the same tend but overestimates the value quantitatively.
波浪浅化时,碎波后主频频率有往低频移动之现象,且波浪进入浅水区,相对水深减小,非线性参数Ursell number越大时,二倍主频及三倍主频与一倍主频能量比值均有增加之现象,与 Stokes三阶理论有相同之趋势,但实验之比值在定量上小於Stokes三阶理论值。

"Wheats are called diploids when they have seven chromosomes, tetraploids when they have fourteen , and hexaploids when they have twenty-one."
其性细胞具有7条染色体的小麦称为二倍体;具有14条染色体的称为四倍体;具有21条的称为六倍体。

Specific bands of D genomes and AB genome in four diploids, four tetraploids and four hexaploids, respectively, could be also amplified by means of M70/E5 1 and M711E5 1 primer combinations screened from twenty pairs of AFLP primer combination for test.
对二倍体、四倍体和六倍体小麦各4个材料的DNA进行AFLP扩增,从20对引物组合中筛选出M70/E51和M71/E51两个引物组合能扩增出D染色体组或AB染色体组的特异性带。

We also simulate the environment of photon experiment, and calculate the effect by use of fourfold symmetry torsion pendulum, we find that the double frequency effect caused by gravitational gradient is reduced a magnitude when we buildup the symmetry of measurement system.
我们还对二重对称扭秤的光子实验数据进行了分析,结果发现二倍频的效应为10~(-12)Nm 的量级,通过计算分析我们发现扭秤周围环境的不对称所引入的引力梯度效应是不容忽视的,因此针对喻家山人防山洞的具体情况,我们对光子实验的实际环境进行了模拟计算,理论分析结果表明对于二重对称的扭秤而言,环境不对称的影响引起的力矩效应为5.4940×10~(-10) Nm,对于四重对称的扭秤来说,效应为1.8668×10~(-11)Nm,可以看到随着扭秤对称性的增加,引力梯度的效应减小了一个数量级。
