In the model, extra-cellular matrix （ECM） was treated as a thin plane. The displacement of ECM is obtained from the force balance equation consisted of the ECs traction, the ECM visco-elastic forces and the exter- nal forces. Simulation results show that a layered capillary network is obtained with a well vascularized region at the periphery of the tumor. The present model can be used as a valid theoretical method in the basic researches in tumorinduced angiogenesis.展开更多

[ Method ] Three kinds of lamps with different wavelengths were used to conduct pest control test in soybean fields. [ Result] The trapping effects of three kinds of lamps with different wavelengths on soybean pests were significantly different. Among them, the trapping effect of No. 2 light with wavelength of 400 -460 nm was significantly better than the other two lamps; No. 1 light with wavelength of 330 -400 nm had no obvious difference in trapping effect with No. 3 light with wavelength of 450 -510 nm. [ Conclusion] The research result provided theoretical basis for popularized application of trapping lamp in production.展开更多
