受主摻質 的英文怎麼說
中文拼音 [shòuzhǔchānzhí]
受主摻質
英文
acceptor dopant-
When a donor or an acceptor impurity is added to a semiconductor, we say that the material has been "doped".
當半導體中加入了施主感受主雜質，我們就說該物質「摻雜」了。The expansion agents can only make up the shrinkage to some extent, and the compensation effects would be reduced when the retardener and fly - ash are used. the expansion agents are not panaceas to avoid the shrinkage cracking as expansion can also reduce the concrete soundness. under bad curing condition, the polypropylene fibrillated film fiber can improve concrete ' s anti - crarking property, while the nominal steels have very unobvious effects. to reduce the concrete shrinkage thus avoid the cracking, the former factors must all be taken into account in concrete proportion design to develop sound concrete
研究結果表明，水泥的品種和用量是影響混凝土收縮值的主要因素之一，當混凝土中水泥用量超過470kg / m ~ 3時，混凝土的收縮值超過400 10 ~ （ - 6 ） ，在約束狀態下存在高開裂風險；採用細砂使混凝土單位用水量顯著提高，收縮值也大幅增加；優質粉煤灰總體上能抑制混凝土的收縮，以超量方式摻入其抑制作用更加明顯，但粉煤灰混凝土早期的粘聚性較差，應注意養護，以免失水產生龜裂；早強減水劑和緩凝減水劑都會使混凝土收縮值增加；膨脹劑只能補償混凝土部分收縮，同時受緩凝劑和粉煤灰的抑制，而且膨脹使混凝土的體積安定性增加了不確定因素，膨脹劑不是解決混凝土收縮裂縫的良方。But the grain growth, grain semiconduction and grain boundary insulation were influenced by many factors, such as the type and contents of dopants, sintering temperature and so on. therefore, in this thesis the effect of the restore sintering temperature, the oxygenize temperature, the donor and acceptor dopant on the dielectric and varistor properties of devices were studied. with sem, the microstructure of srtio3 - based double function ceramic was analyzed
而晶粒生長、晶粒半導化和晶界絕緣化受到多種因素的影響，諸如雜質的種類和含量、燒成溫度等，因此本論文研究了還原燒成溫度、中溫氧化溫度、施主和受主摻雜等對srtio _ 3基陶瓷的壓敏和介電性能的影響，並藉助于sem分析對srtio _ 3基雙功能陶瓷的微觀結構進行了分析。Methods : in cultured lung explants without serum, the lipid component synthesis of pulmonary surfactant was evaluated in [ 3h ] - choline incorporation ; mrna content of phosphocholine cytidylyltransferase ( cct ) in lung explants was investigated in rt - pcr ; the changes of the ultrastructure of the at ii cells were observed with electron microscope ; the expression of nmdar1 subtype was observed in immunohistochemistry staining ; nitric oxide synthase ( nos ) activity, nitric oxide ( no ) content, superoxide dismutase ( sod ) level, malondialdehyde ( mda ) content and lactae dehydroase ( ldh ) level were determined by biochemistry methods. results : 1. influence of glutamate on synthesis of the lipid component of pulmonary surfactant ? with l - arginine, glu inhibited [ 3h ] - choline incorporation with good dose - dependence and time - dependence ; ( 2 ) mrna content of cct of the glu treatment groups was decreased ; ( 3 ) glu increases the release of ldh in cultured lung explants ; ( dwith electron microscope histochemistry, glu induced the changes of the ultrastruture of at ii iv cells
方法：採用成年大鼠肺組織無血清培養，運用[ ~ 3h ] -膽堿摻入法測定ps主要脂質磷脂酰膽堿（ pc ）合成量； rt - pcr擴增檢測肺組織中pc合成限速酶磷酸膽堿二胞苷酰基轉移酶（ cct ） mrna含量；透射電子顯微鏡法觀察肺泡型上皮細胞和ps系統超微結構的變化；免疫組織化學染色檢測glu的受體nmdar1亞單位的表達；生化測定肺組織乳酸脫氫酶（ ldh ）釋放量和肺組織勻漿中一氧化氮合酶（ nos ）活性、一氧化氮（ no ）生成量、超氧化物歧化酶（ sod ）水平以及丙二醛（ mda ）含量。We have investigated the influence on the character of cdte thin films with different conditions and parameters. secondly, in normal temperature, cdte thin films are high resistance semiconductor, for improving its electricity capability, we commonly inject benefactor or acceptor impurities into the pure cdte thin films, the ion influx technique is a good method among many adulteration means. at present, the literatures on the doped cdte thin films by the ion influx technique have a fat lot reports
本論文首先採用近距離升華法在不同基片上制備cdte薄膜，研究了不同工藝條件和參數對cdte薄膜性質的影響。其次，在常溫下，本徵cdte薄膜均為高阻半導體。為了改善其導電性能，通常向cdte薄膜中摻入施主或受主雜質，其中離子注入技術是摻雜方法之一。分享友人
