In this dissertation, the interactive system of Delphastus catalinae (Horn), its preys and competitor was studied, including comparison between alternative preys and natural prey consumed by D.
本文对小黑瓢虫与其猎物及竞争种作用系统进行了研究，其中包括小黑瓢虫取食替代猎物与自然猎物的比较研究，小黑瓢虫与其猎物作用系统研究，小黑瓢虫与其竞争种—刀角瓢虫形态特征的比较研究，刀角瓢虫生物学、生态学及对烟粉虱捕食作用的研究，同时进一步探讨了粉虱的这两种重要天敌—国外引进种天敌小黑瓢虫与本地种天敌刀角瓢虫的种间竞争关系。
By measuring different thickness,the transmission luminious under different cut wave frequencies and the total function coefficient of unit thickness,the μ_t-I curve was plotted,so the relation of absorbency characteristic and thickness and cut wave frequency is studied.
选取青萝卜组织切片为研究对象,立足于应用研究,将青萝卜组织可视为准连续介质,通过测量不同厚度、不同斩波频率下的透射光强及单位厚度的总作用系数,绘出μ-tI曲线,研究其吸光特性与厚度及斩波频率的关系。
