survival curve
解釋
殘存曲線-
The growth dynamics of tree basal area of form. taxus chinensis var. mairei population in different altitude were discussed using the liu - logistic model, and the results showed that the altutide of 790 meters is more suitable to the survive of form. toms chinensis var. mairei population than 990 meters. plot sampling was selected and dynamic analysis was used to study the height structure of taxus chinensis var. mairei population, and the quadrate picture of height structure and the curve of survival rate were drew
運用改進模型對南方紅豆杉種群在不同海拔梯度的種群優勢度增長進行了探討，表明海拔790m處的南方紅豆杉具有較大的環境容納量，但增長速度不快，海拔990m處的南方紅豆杉種群環境容納量不高，但具有較大的增長速度，這可能與群落的發育階段不同有關，兩地海拔均為南方紅豆杉適宜的生長海拔高度，相比而言，海拔790m的珍稀瀕危植物南方紅豆杉種群數量特徵的研究高度更宜於南方紅豆杉種群的生長。 -
In this study, lexa mutant of deinococcus radiodurans xe has been successfully constructed. the survival curve of this strain was measured using colony formation assay after treatment with different doses of radiation and different times of mmc
本研究利用已構建的抗輻射菌lexa基因突變體菌株xe ，經受不同劑量射線照射和不同時間的mmc作用，平板菌落計數，繪制存活曲線。 -
Standard guide for determination of a survival curve for antimicrobial agents against selected microorganisms and calculation of a d - value and concentration coefficient
測定抗選定微生物的抗菌劑的生存曲線和計算d值及濃度系數的標準指南 -
The expression of lexa protein in the iptg - induced jm109 ( pza172 ) was checked by sds - page, and the survival curve of this strain was measured using colony formation assay after treatment with different doses of radiation and different concentrations of mmc
應用電穿孔技術將攜帶有抗輻射菌lexa基因的重組質粒pza172轉入大腸桿菌jm109 ，其啟動子為lacz ，用iptg誘導， sds - page凝膠電泳檢測lexa蛋白的表達。 -
When compared with kds301 ( lexa + ), xe ( lexa - ) cells showed quite similar levels of survival curve to y - irradiation and mmc, indicating lexa gene had no effect on radiation resistance of deinococcus radiodurans. deinococcus radiodurans " lexa had no revelance with its extremely radioresistance. the recombinant plasmid pza172 was constructed by cloning the lexa gene of deinococcus radiodurans into the vector plasmid puc19 in the downstream of lacz promoter
對lexa基因突變體xe的研究表明，其輻射抗性與lexa基因野生型的抗輻射菌kd8301相近，存活曲線上均顯示有一個寬大的肩區，結果發現lexa基因的突變並沒有改變抗輻射菌的獨特抗性，說明lexa基因與輻射抗性無關。 -
One point method, mean square curve method and the maximum likelihood principle to predict p - s - n curve for welded steel structures for arbitary survival rate are presented
本文建立了任意存活率下焊接鋼結構p - s - n曲線預測的一點法，均方差曲線法極大似然法。 -
2, the survival curves of populations of e. chloranthoides in jigong mountain and dongwenquan are diagonal, which indicates that the individuals of each age grade within the two populations possesses the roughly identical death rate and the populations belong to the stable ones, while the survival curve of population in beiwenquan is concave, which shows that the population belongs to the increase one
2 、種群存活率曲線表明，雞公山和東溫泉的縉雲衛矛種群存活率均呈對角線型，說明這兩個種群屬于穩定型，而北溫泉種群的存活率曲線呈凹型，屬于增長型種群。 -
In ion beam - mediated total dna transformation, the total dna consisted of all of genetic information in donor, and had multilateral effects on recipient, so there was no common rate of transformation to measure its effect, which meant that it was very difficult to decide an optimum condition of transformation such as influence. implantation experiments showed that the relation between the influence and survival of a. thailand was a saddle curve
在離子束介導外源全dna轉化中，外源全dna包含有供體的所有遺傳信息，這些外源片段對受體的影響是多方面的，因此轉化效果無法用統一的轉化率來衡量，這就給最佳轉化條件（主要是轉化劑量）的選擇帶來了很大的困難。
