當基體為單晶硅、催化劑鎳膜厚度為20nm 、氨氣氣氛、生長溫度為850時,得到了定向生長的納米碳管。其原因可能是850時氨氣分解的氫原子和無定形炭生成了易揮發物質,從而保持催化劑的活性使納米碳管依靠相鄰碳管之間的斥力定向生長。Electrochemlcal sensor was widely used in the analytical determination recentlythe studyofchemlcal modified electrode ( cme ) whlchact as electrochemlcal sensor was very plentiful the chemical modified carbon paste electrode ( cmcpe ) which was fabricated by mingling modifier with carbonpaste 叩 plledmore often the cpe has the characteristic ofeaslly modified , wide using range , fabricated easily3 innoculty , long llte span etc because modified spedal substance cmcpe has spedal mnctlon , it is studied more and more byelectfochemlcal worker now supermolecule chemistry , the emerging and up to date cross su 刊 ect , involves all su 刊 ects of chemistry biochemistry and material science etc inthatsupralllolecule c 卜 cthlstry chcffi1stfy offers an effective method for chemists to solve the long term puzzle of improving selectivity , ithas gotten a great devebpment from it ’ s theory beingput forward we can expect the greatly wide application ofsupermolecule chemistry on cme but because the difficulty how to station it on the surface of ethetrode cannot be solved easily , the application of supermolecule chemistry on cme was defined
Cmcpe具有了一般碳糊電極的特點,同時又因為修飾了特定物質,使cmcpe具有了特定的功能,越來越受到電分析工作者青睞。而超分子化學是一個新興的跨學科的交叉前沿領域,由於超分子化學解決了一直困擾化學工作者的選擇性問題,因而從其理論提出以來,就得到了巨大的發展。可以預期超分子化學在化學修飾電極方面將有非常廣闊的應用前景,但現在由於將超分子試劑修飾在電極這一環節上存在困難,所以現在超分子試劑在cpe上應用較少,在cmcpe中的應用更少。The interpretation of the rich meaning implied in the novel can be approached from the writer ' s personal life and the social background reflected in the novel. " cat " symbolizes " child " ; the desire for a " cat " ( child ) reflects american new women ' s affirmation of women ' s traditional maternal role in 1920s ; " rain " symbolizes death, hinting not only the abortion of the child but also the end of marriage ; if the " cat in the rain " ( the death of child ) is the internal cause of the collapse of marriage, then the " big tortoiseshell cat " offered by the patron is the external causes ( extramarital affair )
通過分析作家生活經歷和小說反映的時代背景可以解讀「雨中的貓」所具有的多重象徵意義: 「貓」象徵著孩子, 「妻子」對「貓」的渴望表達了女性對母性的期盼,折射了美國20年代「新女性」對傳統女性角色的認同; 「雨」象徵死亡,暗示著人物命運的不幸,既象徵著「妻子」流產的嬰兒,也預示著夫婦婚姻關系的解體;如果「雨中的貓」寓意婚姻關系解體的內因:夫妻在對待生孩子的矛盾,則飯店老闆讓侍女送給「妻子」的「大玳瑁貓」寓意婚姻關系解體的外因:第三者的插足。In some bacteria the pha in the dry cell can be up to 70 % wt by fermentation, but the cost is high. this class includes phb ( poly ( 3 - hydroxybutyrate ) ) and phbv ( poly ( 3 - hydroxybutyrate - co - 3 - hydroxyvalerate ) ). these polymers present the advantages of biodegradability and biocompatibility over other thermoplastics with useful mechanical properties
