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。

This may be due to the characteristics of soybean genome,an ancient tetraploid.

这些基因位于10条不同染色体上，FT类基因具有成对排列于同一条染色体的短的区段的倾向，TFL1和CEN的4个不同拷贝均位于不同的染色体上。7对基因之间同源性高于90%，而且多位于不同染色体上，可能与大豆古四倍体的特性有关。4。

With the giant 201 alfalfa varieties match highly effective nodulestrain is SM29, SM32, SM33 and SM35, after vaccinates above four kind of strains, entire nitrogencontentequally grew compared to the comparison 27.38%; A high comparison equally grew60.27%; The aerial parts dry weight grew 2～3 to double, separately grew 327.00%, 300.65%,280.56% and 279.70%; After the vaccination fresh weight and the comparison compares alsohas theremarkable enhancement, separately grew 148.12%, 132.64%,121.34% and 121.76%.

田间小区试验结果表明，与巨人201高效匹配的根瘤菌株是SM29、SM32、SM33和SM35，接种后其全氮含量分别为27.11％、26.78％、28.92％、27.5％，而对照仅为21.65％；地上部分干重与对照相比，有显著性的增长，分别增长了280.56％、327.00％、300.65％和279.70％，增长了1～3倍，有效地提高了紫花苜蓿的干草产量；接种后地上部分植株高度分别为102.67cm、100.17cm、94.25cm、102.50cm，而对照植株高度为62.33cm；接种这四种根瘤菌，接种效果明显，大大提高了巨人201的鲜草产量，分别比对照增长了121.34％、148.12％、132.64％和121.76％。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
