The hyperbolic Lindstedt-Poincaré method is applied to determine the homoclinic and heteroclinic solutions of cubic strongly nonlinear oscillators of the form  + c_1 x + c_3 x~3 =ε f ( μ, x, ).In the method, the hyperbolic functions are employed inst

调查了国产小汽车尾气非甲烷烃(NMHCs)排放特征,实验在北京工况下在测功机上进行.小汽车NMHCs排放因子为0.9g·km-1,是澳大利亚的2倍,是美国的2~4倍.和美国相比,国产小汽车C4~C7烃的排放比例较高,而C2~C3烃排放比例较低.尾气苯与甲苯比值为0.5,苯与甲苯、乙苯、二甲苯比值(BTEX)为1/2.2/0.1/1.8,这个比值与北京潭裕沟隧道结果基本一致.首次检测到了α-蒎烯和β

本论文报道了在典型配体乙二胺四乙酸(EDTA)和半胱氨酸(Cys)的存在下三角褐指藻(Phaeodactylum tricornutum)对镉(Cd)的富集机制和转化途径.毒性试验表明,两种配体均可有效降低Cd对三角褐指藻的毒性.ICP-MS分析结果表明,EDTA存在下细胞表面吸附和内部吸收Cd的量随着培养液中EDTA浓度的升高(自由Cd2+浓度的降低)而降低,基本符合自由离子活度模型(Free
