查询词典 root system

In this paper, a new method used to deal with the motion ability is studied deeply based on Routh-Hurwitz Criterion. The advantage of this kind of analysis method consists in the fact that after establishing the equation in differential calculus for the motion system, there is no need to know a root of the equation, if you know the root signs, you can judge the zero solution stability of the system.

本文利用劳斯－赫尔维茨判据(Routh-Hurwitz Criterion)对机械系统中离心转速调节器的运动德定性进行了分析，这种分析方法的优点就在于：建立系统运动微分方程的特征方程后，不必求解特征方程的根，只需知道根的符号就可判断系统的零解稳定性。

在生长发育过程中，生长5年的扁蓿豆成株大部分根系外面覆盖了一层厚厚的"根被"，其根系内部多糖存在于次生韧皮部和次生木质部及木质射线中，颗粒在细胞中分布较均匀。

The exterior of root system of alfalfa in adult period hasn't velamen. The polysaccharide in the interior of root system lies in partial secondary phloem and xylem ray of secondary xylem, which doesn't distribute uniformity.

这与苜蓿有差别，苜蓿成株根系外侧没有"根被"，且根系内部多糖存在于部分次生韧皮部和次生木质部的木质射线中，分布不均匀。

Mangroves have a well-developed intertwined root system and can effectively hold back suspended substances of land based sources like mud, protecting coastal banks and embankments from wind and wave. Mangroves have a special ecological adaptability such as viviparity, special root system, ability to filter salt out, etc, and the organisms under the mangroves are diverse. The mangroves can therefore act to purify water and to reduce occurrence of red tides.

红树林由于盘根错节的发达根系，能有效地滞留陆地来源的泥沙等悬浮物质，起到防风消浪、固岸护堤的作用；红树林特殊的生态适应性—胎生、特殊根系、泌盐等，及其底栖生物的作用，使红树林具有净化水体、减少赤潮发生的作用。
