The main study areas are as follows: 1 The landscape classification system of the urban-rural ecotone is set up based on the studying on land-use type of urban area and rural area, and then it is used to establish a regional landscape data warehouse for deposition, modification and management; 2 A group of landscape structure and pattern indices and patch area spectrum analysis methods are used to describe the structural and heterogeneous characters of all the landscape elements from different aspects; 3 The temporal and spatial difference of the landscape pattern of main road belts of the research area are also analyzed with the same method. Their basic process and regularity of urban axial expanding of the southwestward of Shanghai City are initially knewn well; 4 According to the traits of the ecotone, the principles and basis of vegetation classification, the ecotone vegetation classification system is set up, its species constitute, community patch characters, the relationship between vegetation types and landscape categories are analyzed, meanwhile, the vegetation sample maps are made; 5 Based on above studies, some landscape ecological stratedies within the research area were discussed. The following are the results of this study

城乡交错带地区的景观分类，在对城市地区和农村地区的土地利用类型研究的基础上建立了城乡交错带的分类体系，并在此基础上用ARC＼INFO软件分时段、分区、分要素建立研究区的景观图形数据库，对数据进行存储、修改和管理；2）利用多种景观结构、格局指数和斑块面积谱分析方法，从不同的侧面对各种景观组分的结构以及区域的景观格局特征进行了分析，并对其成因进行了探讨；3）利用相同的分析方法，分析了城乡交错带中的城市干道两侧的景观格局特征的空间和时间分异情况，初步掌握上海城市西南轴向扩张的基本过程和规律；4）对城乡交错带中非独立的景观要素-植被，研究其遥感图象信息的基本特征，建立适合区域特点的植被分类体系，并在样区中建立了植被图形数据库和计算机制图，分析了植被景观种类组成、斑块等级等特征以及与不同景观的相互关系；5）在上述研究的基础上，对研究区内的景观生态对策进行了研究。

The off-axis reflection system composed of four aspheric mirrors was designed, but the system structure was not so simple and the performance can also be improved, besides, manufacture and test for large aspheric mirrors are difficult; and then the spherical Fresnel mirror which is easier to be manufactured and tested was used to replace the aspheric mirror, the spherical Fresnel mirror has low cost of replication, but this design also can\'t be used in projection lens because it was only feasible in narrow wavebands; Furthermore, the design making use of catadioptric projection lens was accomplished, this design is greatly applied in rear projector because it has merits of both refraction and reflection. But it had difficulties in color aberration correction and had complex structure.

设计了四片非球面组成的离轴式反射系统，然而，仅采用非球面设计系统结构不够精简，性能也有待进一步提高，且非球面面形较大时加工和检测都存在一定的困难；继而提出了用球面Fresnel反射镜代替非球面的设计方法，虽然Fresnel反射镜加工和检测更为简单，且复制成本低，但对波长具有选择性；进而，应用折反系统结合的方式设计了离轴式投影镜头，该方法因兼具折射和反射的优点，在大屏幕超薄背投系统的设计中广为应用，缺点是会产生难以校正的色差，且结构复杂。

A strip block is used instead of the ball to eliminate the measurement error caused by the trajectory deviation of the ball when passing the photo gate.And a spring clip is used to replace the electromagnet to eliminate the effect of remanence.

在单摆法中，要求忽视细线的质量且线长及小球尺度相比很大，把小球看成质点，并且小球的摆幅不能超过5°[1~3]；在自由落体法中，一般是用小球作为自由落体，但小球通过光电门时，往往不是小球的质心遮光计时，另外，钢球是用电磁铁通电后吸住的，由于断电的瞬间，电磁铁有剩磁，钢球不立即下落，并且钢球应吸在电磁铁的中心处，这些因素都会影响重力加速度的测量。

This method is more convenient, rapid and economical than the traditional Sevag method. A standard strain of herpes simplex virus type 1(HSV-1, SM44 strain) was used to investigate the antiviral activities of PSP in vitro and in vivo. In vitro experiments were carried out in Vero cells, firstly the activity of PSP against HSV-1 was proved to be better than acidovir, which is the most widely used antiviral agent in clinic.
