Different labeling policies are not based on the scientific risk assessment, rather it lies on different political, economic and trade considerations. in this paper, labeling regulations in different countries and territories are reviewed including : the type and scope, the threshold level and exemption, the content of labeling, and the negative labeling for non - gm products. the problems and potential impacts of labeling system on gm products are discus
本文在分析不同國家和地區轉基因產品標識管理政策的基礎上，從標識類別、標識范圍、標識閾值及豁兔政策、標識內容和陰性標識五個方面，對不同國家和地區的標識管理政策進行了比較，並對標識管理中存在的問題進行了分析。 -
In the other way, the more acceptance degree the consumer believe gm food maybe have poison contains or impair the bio - diversity or there are huge difference between gm food and ngm food, the more negative the consumer is
消費者認為轉基因食品與普通產品差別越大越傾向于反對轉基因食品。消費者對轉基因食品可能含有有害物質及影響生物多樣性的確信程度越高越傾向于反對轉基因食品。 -
In the fourth chapter, a fourth - order chebyshev low - pass filter employs new low voltage, highly linear, wide inputting range transconductor is proposed, then we presents a new circuit to tune gm value of transconductor accurately, which employs a new switched - capacitor circuit to change the bias current of transconductor, a third order elliptical function low - pass filter with accurate tunable frequency has been designed using transconductor that is not only with voltage common - mode negative feedback, but also with varying bias - triode transistors which can improve the linearity of this circuit
第四章：提出了一種新的低電壓、高線性度、寬輸入范圍跨導，並由此設計實現了四階切比雪夫（ chebyshev ）低通濾波器，接著提出了一種寬輸入范圍且具有電壓共模負反饋的全差分跨導，並採用一種新的開關電容電路實現跨導值gm精確可調，從而可以設計得到高性能具有精確截止頻率的跨導-電容三階橢圓函數濾波器。
