At present, the air purifying filter is the most economical, effective and the safest defend equipment for purifying air,and its performance primarily rests with filtration material which determines the biosafety of air purifying directly.
目前,空气过滤器是进行空气净化的最经济、最有效、最安全的防御装备,空气净化过滤器性能的好坏主要体现在滤材上,空气过滤器滤材性能直接决定着空气净化的生物安全性。
Clean Air Act Amendment (1987) established a national air-quality standard for ozone.
1987年洁净空气法修正案建立了空气的国家空气质量标准。
Clean Air Amendment (1970) provided stringent automotive, aircraft, and factory emission standards.
1970年洁净空气法修正案规定汽车、飞机与工厂排放标准。

1. STRUCTURE OF THE CLEAN AIR ACT
一、《洁净空气法案》结构
Already some 31 resolutions, amendments and bifis -- from endorsements of Kyoto to modifications of the Clean Air Act -- are kicking around Capitol Hill.
从《京都议定书》的签署到修改《空气洁净法》已有31项决议、修正案和法案有待国会讨论。
Title II of the 1990 Amendments to the Clean Air Act contains extensive new provisions relating to mobile sources.
1990年《洁净空气法案》修正案第二个标题中，包括了一些广泛的有关移动污染源的新规定。
B. REGULATION UNDER THE CLEAN AIR ACT
第二节《洁净空气法案》的规章
The 1977 amendments to the Clean Water Act were an outgrowth of these problems.
《洁净水法案》1977年的修正案，是这些问题的派生物。
That case involved section 211(c)(1)(A) of the Clean Air Act.
此案涉及到《洁净空气法案》的第211条（c）（1）（A）。
A more recent protection for federal lands is to be found in the Clean Air Act.
对联邦土地的保护最近见于《洁净空气法案》。
(2) direct regulation, e.g., emission limitations under the Clean Air Act;
（2）直接管制，例如按照《洁净空气法案》限定排污；
It seems likely that the Clean Air Act similarly has displaced the federal common law pertaining to interstate air pollution.
《洁净空气法案》似乎也有可能取代有关州际空气污染的联邦普通法。
The Clean Water Act was amended by the Water Quality Act of 1987.
《洁净水法案》在1987年修改成《水质法案》。
These provisions provide less guidance than most of the analogous provisions of the Clean Air Act or Clean Water Act.
这些条款与《洁净空气法案》和《洁净水法案》的大部分类似条款相比，提供的指导更少一些。
As we will see, the Clean Air Act contains specific provisions relating to the protection of parks and wilderness areas.
