Thermal adaptation theory predicts that thermoregulative behavior and thermal sensitivity of functional performance should be coadapted in response to certain temperature ***,evidence from empirical studies is *** carried out field and laboratory investigations to determine the adaptive responses of thermal preference and thermal sensitivity of functional performance to the thermal environment in a stream-dwelling turtle (Platysternon megacephalum).The body temperatures of the turtles conformed to the water temperature,with little diel variation in both summer and *** preferred body temperatures(T)and critical thermal maximum and minimum were 25.5℃,3..4.and 5.4., *** assimilation and growth of the turtles were enhanced by ambient temperatures ranging from 16 to 24.,but hampered by thermal environments that mimicked basking(temperature range,19-3.℃).The thermal sensitivity of growth rate differed from that of locomotion;growth was maximized at 24.,whereas locomotor performance was at 3.℃. Consequently,T was more closely related to the thermal sensitivity of growth rate than that of *** thermal preference and thermal optimum of growth,which are closely related to the turtles’ fitness,are coadapted in response to low *** contrast,the evolution of thermal sensitivity of locomotion lags behind,probably because locomotion is not closely related to fitness in turtles or due to evolutionary constraints.

针对limit-checking故障检测方法的缺点,提出了一种基于模糊集的故障检测方法。该方法基于传感器测量值的不确定性和门限值具有模糊的客观属性,在检测值所有可能值的论域上划分模糊子集,将检测值偏离门限值的程度用隶属函数与模糊子集报警权重表示。考虑到时间因素对检测结果的影响,提出采用时间窗函数的方法计算时间窗内的报警权值之和作为模糊检测决策依据。仿真结果表明,基于模糊集的故障检测方法相比于持续性计数(Persistence-Counter)方法具有更好的检测性能。

以山西历山的舜王坪草甸为研究地,运用TWINSPAN和DCA相结合的数量生态方法对9个群落进行划分,得到一个明显的随放牧强度变化的群落序列,即从群落III、IV到群落V、VI再到群落VIII,分别为过牧阶段、中牧阶段和轻牧阶段。可见,利用TWINSPAN和DCA相结合可对不同放牧强度的群落进行划分和排序。从草甸的生态关系研究得出历山山地草甸退化的主要原因是人为干扰。运用DCCA排序法,综合样方和土壤环境因子信息,定量综合研究了放牧草甸与周围土壤环境的生态关系。DCCA第一轴也表现为放牧梯度,在过牧阶段的群落中,有机质和N的含量较高,土壤的退化滞后于植被资源的退化;而在轻牧阶段的群落中,营养元素含量较高。

＜正＞This paper considers the problem of non-regular static state feedback linearization of affine nonlinear systems. First of all, we propose a now canonical form for nonregular feedback linear systems. Using this form, we obtain a special feedback normal form of nonlinear control systems. Based on such a normal form expression we investigate both explicit and approximate linearizations. Several easily verifiable conditions are provided. Finally, the semi-global linearization is also discussed.
