An analytical mosfet threshold voltage shift model due to radiation in the low - dose range has been developed for circuit simulations. experimental data in the literature shows that the model predictions are in good agreement. it is simple in functional form and hence computationally efficient. it can be used as a basic circuit simulation tool for analysing mosfet exposed to a nuclear environment up to about 1mrad. in accordance with common believe, radiation induced absolute change of threshold voltage was found to be larger in irradiated pmos devices. however, if the radiation sensitivity is defined in the way we did it, the results indicated nmos rather than pmos devices are more sensitive, especially at low doses. this is important from the standpoint of their possible application in dosimetry
該模型物理意義明確，參數提取方便，適合於低輻照總劑量條件下的mos器件與電路的模擬。並進一步討論了mosfet的輻照敏感性。結果表明，盡管pmos較之nmos因輻照引起的閾值電壓漂移的絕對量更大，但從mosfet閾值電壓漂移量的擺幅這一角度來看，在低劑量輻照條件下nmos較之pmos顯得對輻照更為敏感。 -
For the acute exposure duration, there expressed the dose - thresholds and time - thresholds in the effects of cu2 + on the activities of cat, pod and sod in two macrophytes. when the test species were exposed at low dose and for a short period, cu2 + can stimulate activities of antioxidant enzymes. once exceeding the thresholds, cu2 + may inhibit enzymes activities
Cu ~ （ 2 + ）低濃度和短時間內對抗氧化酶有誘導作用，超過一定的閾限會產生抑制作用；金魚藻cat 、 pod 、 sod活性在7天內的最大抑制率與暴露cu ~ （ 2 + ）濃度呈顯著正相關。 -
The studies expressed that the tensile - strength declined with the growth of dose rate after the radiation treatment, and at the same time, the gel content had extreme value with the change of the dose rate. the surface of uhmwpe fibers showed some irregular micro - pits and dents after radiation treatment, narnely rough degree increasing. their number and deepness increased with increase of dose. and this phenomenon is the most obvious when the dose rate was 8. 5kgy / s and the dose was 400kgy. at the same time some containing oxygen groups, including hydroxyl group, carbonyl group and carboxyl group, were introduced into the fiber surface which was exposed to the air
研究表明， uhmwpe纖維經電子束輻照處理后，纖維的拉伸斷裂強度隨劑量率的增加呈下降趨勢，凝膠含量隨著劑量率的變化存在極值。纖維表面出現了不規則的微裂紋和凹痕，隨著劑量的增大，電子束對纖維表面的刻蝕程度增加，在本研究中以劑量為400kgy劑量率為8 . 5kgy s時刻蝕效應最為明顯。同時，在空氣中進行輻照時，纖維表面被引入了一些含氧基團，包括羥基、羰基和羧基。 -
The results of statistics showed that maternal age of ds had a tendency to decrease. the results of maternal exposed factors multi - unconditional logistic model showed that long time and low dose radiation and smoked were significantly related with ds

Combined toxicity analysis shows that the interactive effect between methmidophos and cd2 + is antagonistic. 3 ) there are good time - effect and dose - effect relationships between the pollutants and chla contents, which is the chla content of most of group decreases with the increasing of dose and prolonging of the exposure, beside exposed the img / l group of cu2 +, the chla content increases with the prolonging of exposure
除甲胺磷、 cu ~ （ 2 + ）低濃度（ 1mg l ）使chla含量隨污染時間延長而升高外，其它濃度組的污染物均使chla含量隨污染時間延長而降低，表現出良好的時間效應和劑量效應關系。 -
