Finally, several key research fields of EMIS at this stage are given.

指出了现阶段企业MIS系统的研究重点。

Odorous gases have the characteristics of stink emis - sion from fresh waste and landfill gas.

恶臭气体具有新鲜垃圾恶臭排放特征以及填埋气体特征。

Thus total "allowable" emis. ions of each pollutant must be reduced even though a new source is. added.

因此，即使增加一个新污染源，每种污染物总“允许”排放量仍必须减少。

The acoustic emission monitoring of the roof and floor pillars surrounding the stopes was done with YSS acoustic emis-sion meter.

用YSS声发射仪对采场四周的顶底柱进行声发射监测。

The development, characteristics, advantages, heat emis - sion and applications of the stacked 3d packaging technology were introduced.

对其叠层3 D封装的发展趋势、技术特点、技术优势、散热问题以及应用前景等几个方面进行了探讨。
