Two herbicides treating together have an antagonistic action because of some ions of mixture. the mcn and ona inducted by herbicides do n ' t appear in the meantime
可能是其化學成分導致了某種特定的作用機理，使得在與其他除草劑聯合作用時減弱了對泥鰍紅細胞微核的誘變作用。 -
Inductive effects of six herbicides : acetochlor, saturn, nc - 302d ( + ), frifluralin, sofit and 2 - ethyl - 4chloro sodium hydration, on micronuclei ( mcn ) and other nuclear anomalies ( ona ) in erythrocytes of loach were studied
研究了乙草胺、殺草丹、精禾草克、氟樂靈、掃?特， 2 -甲- 4氯鈉水劑等6種除草劑對泥鰍紅細胞核的誘變效應。 -
It distributes widely and survives easily. smears of blood samples were prepared conveniently ; and there is no restriction on seasons. for these reasons, mcn and ona test in erythrocytes of loach is rather useful index for detecting mutagenetic compounds in the aquatic environment
研究結果表明，泥鰍對于核變異的誘發具有較高的敏感性，且泥鰍分佈較廣，易存活，且血量也較搬料多，並能在不同季節評測水質狀況，因此，泥鰍紅細胞微核和核異常測試法可作為監測水環境中致變化合物的一個較為實用的指標。 -
After exposure to weedicide samples for 24h alone, four herbicides ( nc - 302d ( + ), frifluralin, sofit and 2 - ethyl - 4chloro sodium hydration ) can all give rise to the frequencies of mcn and ona ( p < 0. 05, or p < 0. 01 )
精禾草克、氟樂靈、掃?特， 2 -甲- 4氯鈉水劑4種除草劑單獨作用24h所誘發的泥鰍紅細胞微核細胞率間存在顯著差異。 -
In four kinds of weedicides, the average frequencies of mcn in erythrocytes of loach induced by sofit have a obviously increase and significant different in comparison with other three herbicides, it indicates that sofit has greater mutagenic activity and toxicity than other three herbicides
掃?特對泥鰍紅細胞微核的誘變效應最強，掃?特誘發的泥鰍紅細胞微核細胞率與氟樂靈和2 -甲- 4氯鈉水劑差異極顯著，與精禾草克差異顯著。 -
In comparison with herbicides treating alone, the frequencies of mcn of large of experiment groups decline in varying degrees
與單獨作用相比，大部分試驗組的微核細胞率有不同程度的下降，呈現出一定的拮抗性。 -
There are not significant correlation between concentrations and mcn when two herbicides treat together. on the contrary, the frequencies of mcn of large of low concentration groups are higher than those of high concentration groups
除草劑的誘變濃度和微核細胞率之間未呈現出一定的正相關性，相反，大部分低濃度組的微核細胞率不同程度地高於高濃度組。 -
As various kinds of technology including computer, communication, control and cathode ray tube ( crt ) developing quickly, measurement & control network ( mcn ) tends towards networking, distributing, opening and interoperating, which is widely applied in many fields such as industry automation, intelligent building, processing control, etc. firstly, this paper makes a detailed study on the prevalent field control systems ( fcs ), including the characteristics of structure & technology and advantage, introduces several popular field buses, designs the model of field control system, and puts forward three effective methods to integrate between the mcn & information network under different situations
計算機技術、控制技術、通信技術、圖形顯示技術和計算機網路的迅速發展，推動著測控技術向網路化、分散式、開放性和互操作性的方向發展，它被廣泛應用於工業自動化、智能大廈、過程式控制制等領域，大大提高了生產效率與經濟效益。本文首先分析了當前流行的fcs網路的結構特點、技術特點和優勢，介紹了幾種較為流行的現場總線，構建了企業生產的。 fcs網路模型，並提出了在控制網路和信息網路之間加入轉換介面、採用dde技術和使用統一的協議標準三種集成方式。
