We Investigated the species of diseases and insect pests, species of natural enemies, distribution and dominant species in export vegetable bases in Shandong Province. Dynamics of main diseases and insect pests were studied.2. We investigated the main control technologies for diseases and insect pests, types and application methods of pesticides.3. Effects of crop varieties, fertilities and cultivation on diseases and insect pests, production and pesticide residues were examined.4. Control effects and application technologies of frequency trembler grid lamps, greenhouse ozone machine and insect-proof net were tested.5. By research, seven biological preparations and twelve chemical pesticides with high activity, low toxicity and low residue were screened.

Just under this background, studying on the flight mechanism of flapping-wing MAV and sample fabrication from the bionics are conducted in this dissertation. The kinematics equations of insect wings can be acquired by the observation and measurement on the natural insect in researching paper. The geometry model of insect is established by UG technology. The three dimensional grid during the insect moving in the flow field is achieved which adopted grid generation method. The characteristic of lift and drag are attained by simulation the surround flow field during the locomotion of wings, and the flight mechanism of insect is discussed. Based on this study, the physical flapping-wing MAV is fabricated by the acquirable materials and parts of apparatus in existence.
正是在这一背景下,本文从仿生的角度来研究微型飞行器的飞行机理与样机制作;通过查阅文献中对自然界中昆虫翅膀运动的观察与测量,获取了昆虫翅膀的运动方程;采用UG建模技术,建立昆虫的几何模型;采用网格划分方法,获取昆虫在流场运动时的三维网格;运用CFD方法模拟翅膀运动时周围的流场,获取昆虫运动时的升阻力特性,进而来研究昆虫的飞行机理;在此基础上,通过现有可用的材料加工制作仿生微型飞行器。
