on the basis of the analysis of the factors causing the cotton bollworm outbreaks and control failure, the authors recommend that the fundamental strategy for solving the problem of cotton bollworms in China should be to conduct area-wide unified controls rather than depend on insecticides. The unified control system is the guarantee for Integrated Pest Management (IPM) for small-scale crop owners at present. So the authors call on policymakers to put stress on organizing individual growers to carry out area wide unified controls.

Characteristics of geometry of slabs and the intraslab stress filed in the Nankai subduction zone, Japan, were analyzed based on highly accurate hypocentral data and focal mechanism solutions. The results suggest that the shallow seismic zones of the Philippine Sea slab subduct with dip angels between 10 and 2. degrees beneath the Shikoku area and the Kii peninsula. The dip angle of the seismic zone changes from 11 to 40 degrees beneath Kyushu. Two types of seismogenic stress field exist within the slabs of the Philippine Sea plate in the Nankai Trough. The stress field of down-dip compression type can be seen in the slab beneath the region from the western part of Shikoku to the Kii peninsula, where the horizontal component of regional compression stress is nearly in the NWN direction. On the other hand, the stress field of down-dip extension type within the slab is dominant in the region from the western part of Shikoku to Kyushu, where the direction of horizontal compressive stress is near the WNW. Characteristics of geometry of slabs and the intraslab stress filed are related to the slab age of the subduciton zone. The young slab of the oceanic Philippine Sea plate subducts with shallow angle beneath the Eurasian plate in the Shikoku region and the Kii peninsula. The subduction has encountered strong resistance there, resulting in a down-dip compression stress field. The down-dip extension stress field may be related to the older slab of the Philippine Sea plate which subducts beneath the Kyushu region with a steeper dip angle.

On Quadratic Lyapunov Function of Planar Systems

基于ArcEngine和VRML的森林景观可视化系统

＜正＞This paper considers the problem of finding a common quadratic Lyapunov function for a set of planar systems. The main contribution of this paper is to figure out the set of quadratic Lyapunov functions for a given stable planar system. Then a necessary and sufficient condition for a set of plane systems to share a common quadratic Lyapunov function is obtained consequently. It is not only easily verifiable but also constructive. It provides a method to construct all common quadratic Lyapunov functions. As an application, higher dimensional cases are also considered.

新中国成立60多年来,中国法学教育经历了从学习前苏联模式,到借鉴大陆法系模式,又到混合模式,再到中国特色模式初步形成的变迁过程。经过60多年的发展,以多元化人才培养为教育目标,以多轨制法学教育制度为培养方式,以多类型知识建构和多层次学历、学位结构为教育内容,以理论与实践多重组合的教学模式为教育方法,构成了中国特色法学教育模式的基本元素;以教育行政部门的行政管理、司法行政部门的行业指导、法学教育行业协会的自律性管理和法学院校自我管理的四位一体教育管理模式,以法学教育和统一司法考试与法律职业为互动的教育就业机制,形成了中国特色法学教育模式与正常运行不可或缺的保障性机制。历史与现实向我们展示了中国法学教育模式形成的必然性,同时也警示我们存在的问题及其面临的挑战。

In order to supply quality seed for vegetation restoration in arid and semiarid areas of Northwest China, the effects of Platycladus orientalis seed storage under ultra-drying and accelerated aging were studied. The seeds were dried from 6.8% to 5.1%, 4.4%, 3.7% and 2.2. MC, respectively, in a desiccator with the silica gel. The germination energy, germination percentage, germination index and vigor index of the seed were investigated. After ultra-drying, groups of seeds were carried on the accelerated aging tests in an oven at 50 oC for 10, 2. and 3. d , respectively, and the physiological indexes, including relative conductivity, dehydrogenase activity and α-amylase activity were tested. The results show that the ultra-dried seeds with 3.7% MC have the highest germination energy, germination percentage, germination index and vigor index. After aging, the dehydrogenase activity and α-amylase activity of the group of seeds of 3.7% MC were higher than those of 6.8%, while the relative conductivity of the group of 3.7% is lower than that of 6.8%. It is feasible to ultra- dry the seeds with 3.7% MC.
