Illustrations with Real Examples of Using Ecological Regulation Strategies Against Crop Pests in China

In this paper, a series of examples from China, including those using ecological regulation strategies successfully to keep crop pests under control and those making more damages of crop pests caused by wrong cropping systems, crop distributions or extensive cultivation, were given and analyzed. From these, two pieces of experience were enlightened as follows： the first, the refoms of cropping systems and crop distributions must be beneficial to pest control or at least not increase the damage of crop pests; the second, we should further clarify the relationship between population dynamics of pests and cropping system/crop distribution, the basis for correctly laying down the ecological regulation systems.

One modified method of characteristics used to analyze the multiconductor transmission lines

1.INTRODUCTIONThe analysis of electromagnetic compatibility becomesmorei mportant in the analysis of the multiconductortransmissionlines(MTLs).It provides the effectivemethod for designing the MTLs.Several methodsbased on frequency domain and ti me domain tech-niques have beenrecently proposed[1,2].Thefrequen-cy method should performthe inverse Fourier trans-formation,so it is not more accurate than ti memethod to some degree.The method of characteris-ticsis based ontheti me domain met…
