In this research, the plant esterase of wheat and - ethanoic acid naphthalene ester were taken as materials to inspect the relation between the wheat esterase and the organic phosphorus, ten linearity equations were established which expressed the esterase vigor and the organic phosphorus density logarithm with the change of the numerical value of ultraviolet resorption, and the monotony range and the extremum of the function were confirmed
摘要本研究以小麥為植物酯酶的酶源， -乙酸萘酯為底物，考察了小麥酯酶與有機磷農藥之間作用的關系，建立了10個以吸光值變化表示的酶活性與有機磷農藥濃度對數之間的線性方程，並確定了函數的單調區間和極值。Clinical analysis on 12 cases of acute inhalation of high concentration naphthalene vapor
高濃度萘蒸氣急性吸入12例分析In this paper, kandelia candel ( l. ) druce hypocotyls were cultivated in sand and treated with 15 % seawater for 60 days under laboratory conditions. the influence of increasing concentrations of napthalene and pyrene ( 0, 0. 1, 1 and 10mg / l ) on hypocotyl germination and growth, photosynthesis metabolism, water metabolism and membrane protection system were observed to inquire into the ecophysiological responses of mangrove k. candel to pahs phytotoxicity. moreover, the concentration and distribution of parent polycyclic aromatic hydrocarbons ( pah ' s ) in surface sediment, underground root and leaf residue of mangroves in jiulong river estuary ( fugong, north and south shores of haimen island, baijiao ), neighbouring xiamen western harbour ( dong islet ) and dongzui harbour ( fenglin ) were examined
在實驗室條件下，分別以0 . 1 、 1和10mg l的萘（ nap ）和芘（ pyr ） 3個梯度濃度組級砂基培養秋茄（ kandeliacandel （ l . ） druce ）幼苗，培養基鹽度15 ，培養期60d ，以不加pahs為對照，分析了nap和pyr對紅樹植物秋茄幼苗的生長、光合代謝、水分代謝以及膜保護系統的影響，探討pahs對紅樹植物秋茄的的生理生態效應及植物性毒害（ phytotoxicity ）的機理。Osmanthus fragrans cutting propagation experiment showed that there were evident differences between o. fragrans trend branch cutting rooting rates with different rooting drugs and concentration treatments, cutting in summer and in the morning was superior to that in autumn and in the afternoon, the popularization and application of 200 10 ^ ( - 6 ) of naphthylacetic acid treatment and selection of cutting in the summer morning were proper relatively in production
摘要桂花?插繁殖試驗表明：桂花嫩枝?插不同生根素及濃度處理對生根率有明顯的差異，夏插、上午?插優于秋插、下午?播，生產上應採用200 10 ^ （ - 6 ）萘乙酸生根素處理，選擇夏季的上午?插比較適宜。Stationary source emissions - determination of the mass concentration of nitrogen oxides - naphthylethylenediamine photometric method
固定源輻射.氮氧化合物質量濃度的測定.萘二胺光度測定法Electrocatalytic oxidation of glucose at the sensor is determinated with respect to solution ph, temperature and concentration of water - soluble mediator naphthol green b. under optimal conditions, the sensor displays a good linear response in the concentration range of 8. 0 + 10 - 4 mol / l - 3. 6 + 10 - 2 mol / l, and the detection limit is 5. 0 + 10 - 4 mol / l
文中討論了溶解性媒介體萘酚綠b的濃度、溶液的ph值和溫度對該電極電流響應的影響。這一介體型葡萄糖傳感器在優化的實驗條件下，對葡萄糖表現出良好的響應特性，如響應快、重現性和穩定性好。Naphthol green b, which is low cost and easy obtained, has been shown to be an efficient mediator, promoting electron transfer from glucose oxidase to graphite electrode. the naphthol green b has low formal potential, which can reduce the overvoltage of the h2o2 oxidation to eliminate electrochemical interference. rapid response, oxygen independence and high sensitivity are shown by the naphthol green b mediated biosensor
將萘酚綠b作為電子媒介體與葡萄糖氧化酶一起固定於電極，研製出性能優良的新型葡萄糖生物傳感器，其電子傳遞快速，響應時間短，不受氧氣濃度的影響，檢測電位低，抗干擾能力強，靈敏度高。分享友人
