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。

公共权力的强制性使得它具有扩张和被滥用的可能性，从而出现公共权力异化，并在社会生活中直接表现为权力腐败。关于如何有效抑制权力腐败的问题，虽然理论研究成果颇丰，在实践层面上也采取了不少措施，但效果却仍不理想。

Morphological indices of aboveground and underground organs of Plantago virginica were determined using Leaf Area Analysis System (FOCTA STD 1200P) and Root Analysis System (RHIZO STD 1600+) to investigate the influence of population density on the root morphology of the plant.

Results: The hairy root was successfully induced and the hairy root culture system was set up; The opines assay was positive for mannopine and agropine; The result of determination showed that there were a lot of anthroquinone constituents in the rhubarb hairy root and the contents of rhein, aloe-emodin, emodin or 8-O-methylchrysophanol were respectively higher than those in wild plant root.

结果：诱导出了天山大黄发根，并建立了发根离体培养系；从发根中检测到甘露碱、农杆碱的存在；定量分析发现，天山大黄发根中含有多种蒽醌类成分，其中大黄酸、芦荟大黄素、大黄素、大黄酚-8-甲醚的含量分别高于原植物根中的含量。

1 Opens uses this function to enter the memory root table of contents, in the root table of contents can list the system to lack the province folder, the establishment material clamps (when for the first time opening machine or user has not changed table of contents with the user document, root table of contents only has system to lack province folder).

使用该功能进入存储器根目录，根目录中会列出系统缺省文件夹、建立资料夹和用户文件（首次开机或用户未更改目录时，根目录只有系统缺省文件夹）。

The generation process of the stiffener layout on a vibration-proof plate and shell structure can be regarded as the growing process of a root branch system in plants, thus the stiffeners are started from the so-called seeds, and are grown, branched off or degenerated according to a certain growing rule similar to that of a natural root branch system.

将结构加强部件分布的形成看成和植物根系的成长过程一样，加强部件从给定的&种子&出发，根据一定的成长规则生长、分歧或退化，在体积增量的控制下，形成最优的分布形态。

Inwheat intercropped with soybean not only N situation could be improved butalso P situation could be.2In intercropping,the pH of soybean rhizospherewas decreased by increasing the R-Apase activity,which could decelerate thetransforming and fixing P fertilizer.3In both monoculture and intercroppingsystem,the soil pH of rhizosphere was affected by cropping system at two Plevel which only 0.1-4mm distance from the root surface,but the effect of S-Apase activity in the rhizospher soil by cropping system was less than3mm.In effect,the rhizosphere P was really available nutrient,and applyingP to rhizosphere was effective ways to reduce the P nutrient competition.4Inwheat/soybean intercropping,the peak stage of reduction ability of roots wasthe same as that of the root growth,so that the time compensation appearedin intensity of nutrient absorption.

间套作大豆、小麦、玉米根系Apase的差异又反映出大豆利用土壤磷的潜在能力最大，而玉米最小，可见禾谷类的小麦与大豆间套后不但能改善小麦的氮素营养状况还使磷素营养也得以好转。2）间套大豆根际pH值的下降，导致磷肥施入土壤后形成〓-P的比例显著提高，转化成〓-P等难溶性磷减少，说明间套的大豆能减缓肥料磷在土壤中的转化和固定，减少磷素向无效化方向转化。3）复合群体根际土壤pH值的影响一般只发生在0.1-4mm的根际微区，而土壤磷酸酶的影响供磷与否在距根表3mm以外都无多大差异，说明根际磷才是真正有效磷，根际施磷是解决磷素竞争的有效途径。4）。
