1) boundedness and persistence
有界持久性
1.
Some sufficient conditions for boundedness and persistence and global asymptotic stability of solutions for a class of delay difference equations with higher order are obtained, which partly solve G.
获得一类高阶时滞差分方程解的有界持久性和全局渐近稳定性的充分条件;所得结果部分地解决了G。
3) Persistent toxic substance
持久性有毒物质
1.
Persistent toxic substances (PTS), such as persistent organic pollutants (POPs) and heavy metals, migrate with atmospherical settling, raining and surface run off, deposit in soils and sediment and lead to soil and sediment pollution.
持久性有毒物质(Persistent toxic substance, PTS)如持久性有机污染物(Persistent organic pollutants, POPs)和重金属等进入环境后,随大气沉降、降雨和地表径流等迁移并最终在土壤/沉积物上沉积,造成土壤/沉积物的污染,因而对污染土壤/沉积物的修复非常必要。
4) boundary and persistence
有界保持性
1.
And we provide a partial answer for Ladas G Equation with the necessary condition and sufficient conditions of the boundary and persistence.
本文运用母函数等方法得到了一类线性和非线性时滞差分方程的通解 ,从而解决了这类方程的有界保持性问题 。
5) persistent organic pollutants(POPs)
持久性有机污染物
1.
Because PAHs are hydrophobic,carcinogenic,teratogenic,mutagenic and disbiodegradable,they are regarded as the major representation of persistent organic pollutants(POPs).
多环芳烃主要来自于碳氢化合物不充分燃烧,在大气、水体和土壤中广泛地存在,由于多环芳烃具有疏水性、致癌性、致畸性、致突变性和生物难降解性,因此多环芳烃被看作是持久性有机污染物的主要代表。
2.
In order to explore potential healthy hazards of persistent organic pollutants(POPs) in the Three Gorges reservoir,a water environmental health risk assessment model was established based on an introduction of the health risk assessment method.
为研究三峡库区水环境中持久性有机污染物(POPs)对人体健康产生的潜在危害风险,在介绍健康风险评价方法的基础上,建立了水环境健康风险评价模型,根据三峡库区水质监测资料对水源水主要持久性有机物多环芳烃和邻苯二甲酸酯类污染进行健康风险评价。
3.
It was discussed that short chain chlorinated paraffins which belongs to persistent organic pollutants(POPs)will be controlled by the Stockholm Convention and it will affect Chinese chlorinated paraffins industry.
简述了我国氯化石蜡的产业现状,分析了将属于斯德哥尔摩公约受控范围的持久性有机污染物短链氯化石蜡对我国氯化石蜡产业的影响并提出对策建议。
补充资料：持久性毒剂
分子式：
CAS号：
性质：毒害作用持续时间为几小时，甚至数天以上的毒剂。通常为沸点高、不易挥发的液态毒剂。主要呈液滴状态，用于地面染毒。如芥子气、维埃克斯。
