多溴联苯醚(PBDEs）是一大类溴代阻燃剂,曾在家电、纺织品等家用产品中广泛添加.虽然目前商用五溴、八溴和十溴联苯醚已相继被斯德哥尔摩公约和其他地方法律禁用或限用,但由于该类物质的亲脂性和结构稳定性,因此在世界各地的各类动物、人类组织和环境样品中均有检出,且浓度呈逐年增长的态势.其中2,2,4,4-四溴联苯醚(BDE47）不仅是产量最大的一种PBDEs同系物,且在多项毒理学研究中均表现为毒性最强的
随着社会文明的进步,清洁能源以及生态环境越来越受到人们的关注.超级电容器是一种新型的储能器件,由于其功率密度高、无污染和易维护的优良特性,在混合电动汽车和便携式电子设备等方面展示了很好的应用前景[1].
Mathematical modeling is an effective and powerful tool in understanding complex biological phenomena.These models,using tools from diverse areas of mathematics ranging from partial and ordinary diffe
The purpose of the present paper is to understand general equilibrium implications of international trade and globalization on social welfare and environmental emission caused on account of energy con
In this work we use a combination of mathematical modelling,numerical simulation and optimal control of partial differential equations in order to mitigate the urban heat island effect(a metropolitan
Ill present a numerical scheme able to handle discontinuous solutions arising from problems with interfaces.
A computational framework is presented for materials science models that come from energy gradient flows such as the Cahn-Hilliard equation.
We consider the Lam′e system with partial infinity coefficients in dimension two which describes a model of a linear isotropic elastic body containing two adjoint inclusions with infinity elastic para
Dislocations are line defects in crystals.Their motion and interaction is considered the fundamental mechanism for plastic deformation in metals.
This work solves the Schrdinger equation with superposed potential(IQYIQP)made up of inversely quadratic Yukawa(IQY)potential and inversely quadratic(IQ)potential using the Pekeris-like approximation
