寄主对棉铃虫(Helicoverpa armigera Hübner)越冬蛹抗寒能力的影响

通过对滞育蛹过冷却点的测定,初步明确寄主对棉铃虫的越冬抗寒性有影响,采自棉花的滞育蛹过冷却点低于采自玉米的滞育蛹,即前者的抗寒能力高于后者;但用抗虫棉喂养后的棉铃虫滞育蛹抗寒能力下降.     

方程f″—zf=0解的零点

首先于实数域内，用ｓｔｕｒｍ比较定理证得ｆ″－ｘｆ＝０的非平凡解的零点集含有可列个负数；尔后延拓到复数域内，把特解Ａｉｒｙ积分Ａｉ（ｚ）用Ｍａｃｄｏｎａｌｄ函数表示。通过复围线积分计算证得Ａｉ（ｚ）仅有负数的零点，从而获得了ｆ″－ｚｆ＝０的非平凡解有且仅有可列个负数零点的结论。

Studies of Several Systems with Air Electrode Electro-Synthesizing H2O2 on the Spot for Degrading Aniline in Aqueous

A gas diffusion electrode (air electrode) with a high current efficiency of electro-synthesizing H2O2 using O2 in air was prepared. The several systems with air electrode as cathode of electro-synthesizing H2O2 on the reaction spot for degrading aniline in aqueous--electro-Fenton system, photo-excitation electro-H2O2 system and photo-electro-Fenton system, were developed. The rates of decomposition of H2O2 and mineralization of aniline were experimentally measured respectively under different conditions, and the results indicated there has an excellent parallel relation between decomposition rate of H2O2 and mineralization rate of aniline. Especially, photo-electro-Fenton system, where H2O2 is decomposed the fastest, is the best system of oxidizing and degrading organic toxicants. Compared photo-electro-Fenton system with photo-Fenton system, important role is revealed in the interface of air electrode. In this paper, the mineralization mechanism of aniline in the photo-electro-Fenton system was also discussed.
