quenching rate
解釋
淬火率-
After the stolon had suffered from severing disturbance, clonal ramets could keep photosynthetic organ from being damaged through the plastic responses of the chlorophyll fluorescence traits, such as increasing nonphotochemical quenching of chlorophyll fluorescence ( npq ), decreasing actual photochemical efficiency of ps ii in the light ( f / fm " ) and photochemical electron transport rate ( etr ). moreover, the clonal ramets could also increase water use efficiency by means of decreasing stomatal conductance
在匍匐莖受到切斷干擾后，臭柏能通過提高非光化學猝滅（ npq ） 、降低ps實際光化學量子產量（ f fm 』 ）和表觀光合電子傳遞速率（ etr ）等葉綠素熒光特性的可塑性反應來保護小枝光合機構不被破壞，並且可以降低氣孔導度以提高水分利用效率。 -
A does - dependent study of the aba - induced oxidative burst was observed, in which both the magnitude and rate of dye quenching was directly related to the concentration of aba. and the treatment of the guard cells with catalase of 100 units / ml nearly completely obliterated the quenching reaction induced by 10 | amol / l aba ( final concentration )
因此， aba可以誘導氣孔保衛細胞產生h2o2 ，其產生的強度和速度與aba的濃度直接有關，並且推測：這種h2o2產生可能是aba誘導氣孔關閉過程中信號轉導鏈的一個中間成分。 -

The preparation of optically active composite is a promising alternative to obtain a kind of new and competitive sensing membrane for fiber optic sensors, and has attracted the global attention. in this thesis, the modified sol - gel sensing membranes based on fluorescence quenching have been prepared by using tetraethoxysilane ( teos ) and dimthyldimethoxysilane ( dds ) as the main material, formamide as the drying control chemical additive ( dcca ), ru ( phen ) 3cl2 and ru ( bpy ) 3cl2 as the indicator. this kind of membranes is crack - free and has low indicator - leaking rate
本文以四乙氧基硅烷（ teos ） 、二甲基二乙氧基硅烷（ dds ）為主要原料，以甲酰胺為控制乾燥劑，二價釕離子絡合物釕（ ） ?聯吡啶（ ru （ bpy ） _ 3cl _ 2 ）和釕（ ） ?菲咯啉（ ru （ phen ） _ 3cl _ 2 ）為熒光指示劑，採用改進的溶膠凝膠技術，通過添加控制乾燥劑和有機摻雜兩種手段，制備了基於熒光猝滅原理的光纖氧敏感膜。 -
Part i this paper has minutely studied the interaction between ag ( i ) and serum albumin. the binding of ag ( i ) to human serum albumin ( hsa ) or bovine serum albumin ( bsa ) has been studied by equilibrium dialysis at ph ( 5. 4 ). the scatchard analysis indicates that there exists several strong binding sites of ag ( i ) in both hsa and bsa. a notable hysteretic effect has been observed in the interaction of ag ( i ) with hsa or bsa using uv - visible spectrometry at ph ( 5. 4 ), which shows that the binding between ag ( i ) with hsa or bsa may induce a slow transition of hsa or bsa from the conformation of weaker affinity for ag ( i ) to one of stronger affinity ( a - b transition ). the rate constants and activation parameters of this transition parameters of this tansition were measured and discussed. the binding equilibrium has been also studied by resonance light - scattering spectrum ( rls ) and flurescence quenching
第一部分：等離子點ph （ 5 . 4 ）條件下，用平衡透析法和紫外光譜，熒光光譜，共振散射光譜研究了ag （ ）與人血清白蛋白（ humanserumalbumin ，簡稱hsa ）或牛血清白蛋白（ bovineserumalbumin ，簡稱bsa ）的結合。 scatchard圖分析表明， ag （ ）在hsa或bsa中有強弱兩類結合部位，通過計算機擬合獲得結合的逐級穩定常數值。紫外掃描發現ag （ ）與hsa或bsa的結合存在滯後效應，表明ag （ ）與hsa或bsa的結合可能誘導蛋白質構象發生緩慢變化（ a - b ） ，測得並討論了這一構象變化的速度常數和活化參數。 -
