通過電學和熱學性能測試結果表明,電導率隨著sr含量的增加以及溫度的變化都出現了極大值,在本論文中,在sr含量為0 . 4時電導率值最大,電導率最大值對應的溫度隨著sr含量的增加而降低,這是由於在低溫下以小極化子導電機理為主,在高溫階段則是氧空位的電荷補償占據主導作用,氧空位使得載流子的濃度和可動性減弱,從而導致電導率降低。Why power quality questions are attracting attention increasingly has three chief reasons : the electricity load structure occurs the great change in the modern power system ; very sensitive to power quality control equipment and the electronic installation service based on the computer system of large numbers have been used ; in the power market under the operating mechanism, power is as the commodity, and users certainly puts forward the more and more higher requirement to the commodity quality
電能質量問題之所以日益受到重視主要有三個原因:現代電力系統中電負荷結構發生了重大變化,諧波源的種類和數量增加;大量對電能質量非常敏感的基於計算機系統的控制設備和電子裝置投入使用;在電力市場運行機制下,電能作為商品,用戶必然對商品質量提出越來越高的要求。On the whole, the surface charge of chloroform is negative. thus, both the adsorption capacity of granular activated carbon and attractive or repulsive forces of charge influence the electrosorption of chloroform on granular activated carbon
陽極極化時,活性炭表面帶正電荷,吸附點增加,吸附量與吸附速率提高;相反,陰極極化則活性炭表面的負電荷與氯仿異性相斥,吸附量減小。The effects of the higher - order terms on the self - deflection process of photorefractive bright solitons in a crystal are also investigated. compared the results of first - order diffusion term acting alone with both the first - order diffusion term and the higher - order space charge field terms acting together, the screening solitons always bend right, whereas for the self - deflection of the photovoltaic bright solitons and the screening - photovoltaic bright solitons both bending right or left is possible, and it is possible that no self - deflection process occurs
