And its usage on cmcpe was further less . three organic reagents were used as modifier in the fabrication of cmcpe bonded with solid paraffin in our research 本文首先以固体石蜡为粘合剂,以三种常见有机试剂及其特定的形式作修饰剂制备了cmcpe ,并分别用作电流型和电位型电化学传感器测定金属离子。
When formed for 8h , because most of paste on the negative plate has converted into lead , the polarization increases and the potential changes greatly , these distributions on the two kinds of negative plates become non - uniform again 当化成8h时,由于负极板上的铅膏大部分转化为铅,极化上升,电位变化很大,所以两种负极板上电流密度和电位分布又变得不均匀。
When it is discharged at high - rate , the distributions are also the most uniform at the end of the discharge . this indicates that the positive plate with the red lead has the better discharge performance than the other two kinds of positive plates 含红丹的正极板在化成初期电流密度和电位的分布最均匀,极化最小,在高倍率放电结束时,其电流密度和电位分布也最均匀,表明含红丹的正极板的放电性能比其它两种正极板好。
For special example , the closed form solutions for complex potentials in matrix and inhmogeneity regions are derived explicitly when interface containing single crack or rigid line , and the appropriate expressions of the electro - elastic field intensity factors at the tip of crack or rigid line are examined 作为特例,求出了界面含一条裂纹或刚性线夹杂时基体和夹杂区域复势的封闭形式解;同时计算了界面裂纹和刚性线尖端应力和电位移场强度因子。
Abstract : 5 - fu liposome was prepared by the reverse evaporating method . then the entrapment reached 43 . 31 % by freeze - thawing 5 - fu liposome several times . the centrifugal accelaration experiment and the measurement of potential proved that the stability of the liposome could be ameliorated 文摘:采用反相蒸发法制备5 -氟尿嘧啶脂质体制剂.结合冻融法,可使5 -氟尿嘧啶的包封率达( 45 . 31 0 . 2085 ) % .离心加速实验和电位的测定进一步验证了冻融法可使脂质体稳定性提高
