The current analytical standard for demonstrating adequate decontamination of facilities, separation within the same building, or measurement of cross-contamination is codified at 21 CFR 211.176 and 436.104 and has a limit of detectability of 0.006 ppm (as Penicillin G using S. Lutea) and a violative detection amount of 0.03 ppm.

现在证明厂房能被足够去除污染的分析标准，同一个建筑物内的隔离，或者交叉污染的检测在21 CFR 211.176 和436.104中作了规定，LOD为0.006 ppm，不可接受的检测数为0.03 ppm。。

The objective of the dissertation is to find a way to improve Freight service of TRA under the circumstances described above.From the view of external cost of overall transportation, railway is the most cost effective vehicle in terms of external cost if we count the cost of green house effect, air pollution, noise pollution, and accidental cost.

就总体运输之外部成本而言，运具能源耗用所产生的温室效应、空气污染、噪音污染、肇事成本等，铁路运输所产生之外部成本远较公路运输为低。

The water pollution of inshore region is more serious at present than before in our country. To control the water pollution of the inshore, the hydrodynamic characteristic and mass transportation process should be simulated and reproduced.

目前我国近海水域污染形势严峻，为了控制近海水域的污染，必须对近海水动力特征和污染物输运过程进行模拟和复演。

Only average percentage of Al in episode days is high than that in nonepisode days.The A/C ratio of the cation or anion in PM10 is greater than 1 for every sampling situation. It was highly correlate between NH4+ and NO3-, NH4+ and SO4-2 of PM10 particle among four sites. The NR of each site was all 1. It means that the PM10 particle is acidulated during the sampling period and that phenomenon worth to be researched further in the future.

无论污染事件日、非污染事件日或日、夜间，各测站PM10上阴、阳离子当量比之比值均大於1；各测站PM10微粒中NH4+与NO3-间及NH4+与SO4-2间均呈高度之相关性，其PM10微粒之中和比值(neutralization ratio；简称NR)均小於1，表示各测站在本研究之采样期间，其PM10微粒均偏酸性，其原因未来值得深入加以探讨。
