A new switching scheme to the gain of variable structure control signals is proposed. The following important open problems in standard VS-MRAC and MRAC are solved by using the scheme: 1 . a prespecified transient and steady-state performance index for tracking error can be achieved without requiring any information about the plant high frequency gain sign when relative degree of modelled part of plant is one, and 2 . it is shown that as long as the performance indexes are guaranteed for the auxiliary errors, each of which in dynamics is a sub-system with relative degree one, the tracing error will converge to a small residual set in a prespecified transient time when relative degree of modelled part of plant is greater than one.

提出了一种控制增益可切换的变结构自适应律，解决了如下变结构模型参考自适应控制（包括基于调参律的模型参考自适应控制）理论研究中长期没有解决的问题：当对象建模部分相对阶为1、高频增益符号未知且存在非线性输入扰动和未建模动态等情况下，系统跟踪误差可满足预先给定的动态和稳态性能指标；当对象建模部分相对阶大于1且存在非线性输入扰动和未建模动态时，可保证系统跟踪误差在预先给定的过渡过程时间内收敛到一个残差集中； 5。

研究结果表明，郁闭度与活地被物负荷量呈负线性相关关系，龄级与其呈正线性相关关系；故郁闭度与死地被物和总地被物负荷量呈正线性相关关系，龄级与其呈正线性相关关系；蓄积量与地被物的负荷量呈线性正相关关系，但相关性较小。

Two sibling species Helicoverpa armigeraH(u|¨bner and H.assulta are serious crop pests in China.They have the similar morphological,biological and ecological characterstics,as well as they can even hybridize with each other.Their host plant ranges, however,are quite different.The former is a typical polyhpagous species,and its host plant range including at least more than 60 crop species such as cotton,corn,wheat,soybean, tobacco,and tomato,and 67 wild plant species from about 30 plant families including Malvaceae,Solanaceae,Gramineae,Leguminosae,etc.

The plant floating-bed technology application in Miaojia river showed that the water quality of the plant foating-bed technology applied had preceded evidently than the comparing water, though the water quantity was exchanged largely. There existed a micro-ecosystem at the root aera of floating-bed plant which mainly consists of organic grain, algae, zooplankton, zoobenthos. The mode of "Oenanthe javanica -Ipomoea aqutica" floating-bed mode application realized the whole year run of plant foating-bed technology on polluted water. Hence, the mode is suggested in the following application.
