四倍

Polymorphism in diploid species G.arboreum was the same as in tetraploid species G.hirsutum,both were 11.84%.

在二倍体棉种中棉的扩增多态性率为11.84%，与在四倍体棉种陆地棉的扩增多态性率相同。

Through chromosome identification, the chromosome numbers of diploid and tetraploid were 16 and 32, respectirely.

染色体鉴定表明，二倍体染色体数为2n=2x=16，四倍体染色体数为2n=4x=32。

The former was 176.1% higher than the latter. The comparison is helpful for promoting high quality tetraploidy raploidy strain.

四倍体药蒲公英中咖啡酸含量高，是一种值得推广的优质多倍体蒲公英新品种。

The velocity of sound in water is 4900 ft Per second ,or more than four times its velocity in air

水中的声速成为每秒4900英尺，比空气中的声速大三倍多（直译则为：……是空气中声速的四倍多

We analyzed the electrophoritic patterns of 16 kinds of isozyme and three kinds of storage protein in Agropyron elongatum 2x and Ag.

应用等电聚焦和SDS-PAGE方法分析了二倍体长穗偃麦草(Agropyron elongatum 2x)和四倍体长穗偃麦草Ag。

The phylogenetic analysis based on the sequences in this region indicated that the y-type HMW glutenin subunits of Agropyron elongatum species were different from other subunits, whereas the x-type subunits of them were most closely related to that from the B genome.

推测四倍体长穗偃麦草中的E1基因组可能起源于二倍体的E基因组。与来自小麦族的A、B、D和G基因组部分亚基基因的启动子序列比较表明，小麦族的这一区域在进化上是相当保守的，不同基因组来源的序列同源性都在90%以上。

Study on genetic characters in diploid and tetraploid of dactylis glomerata.

二倍体和四倍体野生鸭茅遗传特性比较研究。

Current, electronic business affairs still is in grow at the speed of traditional and retail industry fivefold with arriving quadruply.

现在，电子商务仍然在以四倍到五倍于传统零售行业的速度增长。

It is made of modern new-type materials by repeated hi-tech compound shaping. Ideal for sunray blocking, it has the following features: small, elegant, easy to use, not taking too much room, and with double alarm system.

它的实际遮阳率高达80%，是太阳挡25%的3倍多，是防爆膜20%的四倍，而且体积小、外形美观、使用方便（拉出来使用仅需10秒钟）、价格适中。

In contrast to the granular shape papillaes around the stomata and less density of trichoma on costal zones in tetraploidies of O. officinalis, the triangle and overarching shape papillaes, and denser trachoma were observed in diploidies.

在O。 officinalis中，四倍体有粒状气孔器外围乳突和脉带表皮毛较少，二倍体细胞型具有三角形拱状排列的气孔器外围乳突和较密集的脉带表皮毛；而在O。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
