A Brief Discussion on Dynamic Control System
of Automaticaly Monitoring Polutant Source
Wang Jinlei
(Liaoning Environmental Monitoring Center,Shenyang110161,China)
Abstract:As the environmental protection department adopts automatic monitoring data of polutant source more
often,people pay more and more attention to the authenticity and validity of the data.In normal operation,the real
-time data of automatic monitoring equipment can accurately reflect the situation of the enterprise's production and
polution discharge,but some enterprises which are driven by economic interests may try to hide the truth through
various means.The dynamic control system which automaticaly monitors polutant source is an effective solution to
that problem.The article also introduces the overal design,composition and prospect of the system.

灯台树的播种繁殖
灯台树属山茱萸科灯台树属,落叶乔木,高10~15m。其别名女儿木、六角树,以树姿优美奇特,
叶形秀丽、白花素雅,被称之为园林绿化珍品。
灯台树喜温暖气候及半荫环境,适应性强,耐寒、耐热、生长快。宜在肥沃、湿润及疏松、排水良
好的土壤上生长。定植或移栽宜于早春萌动前或秋季落叶后进行。种植穴内施适量基肥,栽后浇足
定根水。生长期要保持土壤湿润,2~3年施肥一次。由于自然生长树形优美,一般不需要整形修剪。
病虫害少,管理简单、粗放。
台灯树采用播种法繁殖。10月份采收果实,堆放后熟,洗净阴干,随即播种.或低温层积沙藏,于
翌年3月露地条播。行距50~60cm,株距10~15cm。4~5月份便可出苗。第一年根系不发达,生长
量小,高约30cm左右,第二年生长量可达50cm,三年以上每年以1m以上的速度生长,并呈现出优美
的冠形和树姿,达到满意的观赏效果。
