中文拼音 [qíhuàfǎnyīng]
歧化反應
英文
disproportionation reaction-
This reaction involves disproportionation of the aldehyde.
這個反應就是醛的歧化作用。Aim the stability of steady state and bifurcation in a autocatalytic reaction diffution system are to be studied
摘要目的研究一類自催化反應擴散系統平衡態的穩定性與分歧。When termination occurs partly by disproportionation, the prepolymer chains in the product carry branches as well as cross-links.
當終止反應一部分是由歧化所起時,則在產物中預聚物鏈不但帶有交聯也帶有支鏈。The fouling of monomer recovery system of qilu esbr plant was studied. it was con sidered that the fouling was principally caused b y the following four reasons, there existed the colopholic potassium containing c onjugated doublebonds in the disproportionated colopholic potassium, excessive co ntent of c16 - 18 compositions existed in the fatty acid, excessive content of com positions for which the demol condensation degree was above 5, the reaction conve rsion was higher than 72 percent. effective countermeasures were proposed
介紹了齊魯引進乳聚丁苯橡膠裝置回收單元存在的設備堵掛問題,經分析認為歧化松香酸鉀中帶有含共軛雙鍵的松香酸鉀,脂肪酸中c16 18組分含量高, demol縮合度高於5的組分高,反應轉化率高於72 %是造成堵掛的4條主要原因,提出了對策。In addition, no back mutation to obtain a maximal complexity ( i. e. - resistant and sensitive species coexistence ) or original ecology ( i. e. original - lysogen ) for the evolution occurs
而且,逆反應變異回原有菌相而成對噬菌體敏感及阻抗菌相共存之最大分歧度或回歸至起始單一對噬茵體敏感菌相併未曾演化發生。This phenomenon, however, is not much discussed in society. to rectify the indifferent attitude of people towards the elders, the government should ask the mass media, including television, movie, newspaper, and advertisements, to show the image and contribution of the elders in a relatively positive manner. the mass media should not distort the image of the elders and in turn harm their self - confidence
近年來廣告對長者形象常有歧視性的態度或做法,社會反應不大,顯示社會人士及傳媒對長者是否有歧視性的態度或做法,影響長者的福祉的情況較少關心,政府應要求大眾傳媒,以較正面的方法表達長者的形象及貢獻,而不應醜化長者,影響長者的自信與形象。Disproportionation reaction, dismutation reaction
歧化反應In the second part, we consider a class of reaction - diffusion equations in developmental biology. near the bifurcation points, using the liapunove - schmidt reduction process, we obtain the nontrivial solution branches which are bifurcated from the trival solution when the parameter changes
然後考慮發育生物學中一類反應擴散方程組,在分歧點附近利用liapunov - schmidt約化技巧,得到了從平凡解分歧出來的隨參數變化的非平凡解枝以及它們的近似解析表達。The positive transformants with the integrates mn - sod gene was identified by zeocin - resistance, pcr screening and expression in p. pastoris. the recombinant mn - sod protein was successfully expressed in pichia pastoris based on the evidences that a relative molecular weight about 23kd appeard in sds - page, the obvious activity of sod existed in native - page and enzymatic activity test, and mn - sod activity was specific base on the inhibition with the mixture of chloroform - enthanol ( 3 : 5 / v : v ) and potassium cyanide. two secreted plasmids ppiczaa - sodm18 and ppiczaa - sodc were constructed and after there linearization were transferred into chromosome of pichia pastoris gs115 by electroporation
Pcr鑒定及mut表型分析進一步說明,目標基因已經重組到宿主菌基因組染色體上; 0 . 5甲醇誘導表達后, sds - page結果顯示,表達的蛋白相對分子量約為23kd ,活性電泳出現明顯活性條帶;酶活性測定顯示,重組菌株sod活性比對照提高5倍左右;氯仿-乙醇( 3 : 5 v : v )和kcn ( 5mmol l )抑制反應進一步證明,所表達的sod為錳超氧化物歧化酶。分享友人
