The shellac erythrophyll is from the parasitism the resinous substance shellac which in places the such as india, thailand, burma, china leguminosae, on the mulberry branch plant s lac insect secretes with the thin sodium carbonate watery solution extract fine but, assumes the reddish purple color either the bright red powder or the liquid, by shellac acid a and shellac acid b, c, e and so on is composed, serves as the edible erythrophyll, when the acidity assumes the orange, is extremely stable
紫膠紅紫膠紅色素是從寄生於印度、泰國、緬甸、中國等地的豆科、桑科植物上的紫膠蟲所分泌的樹脂狀物質紫膠用稀碳酸鈉水溶液萃取精緻而得,呈紅紫色或鮮紅色粉末或液體,由紫膠酸a和紫膠酸b 、 c 、 e等組成,用作食用紅色素,酸性時呈橙色,非常穩定。As for fresh male adult cadaver, inject 8 % gelatin carbonic ink, 14 % ammonia and red gelatin until the ventral skin of the toe turn red from black, washing 6 hours by flowing water. cutting the scapular flap, anterolateral femoral flap, chest - umbilicus flap and medial superior genicular flap, after washing and rot prevention, inject 8 % gelatin ink solution into artery
新鮮男性成人屍體1具,于雙側股動脈插管內分別先後行8明膠碳素墨汁14氨水紅色乳膠溶液灌注,至趾腹顏色由黑變紅為止,流水沖洗6小時。Results came as follows : in this dissertation, we found that it was the smallness of the positive electrode capacitance that limits the performance of carbon based supercapacitors in alkaline electrolytes, and the performance could be meliorated if the active material loaded on positive electrode increased. activated carbon electrode was proved to have good capacitor performances in neutral electrolyte such as ammonium sulfate solution and ammonium nitrate solution, but a correlated problem is the corrosion of the metal current collector
本文通過考察活性炭電極在堿性電解液中的電極行為,指出活性炭電極在堿性溶液中正極性能較差是影響碳基超級電容器性能的重要因素,增大正極活性物質的載量能夠使電容性能得到一定程度的改善,同時發現活性炭電極在硫酸銨和硝酸銨等中性電解液中具有優越的電極性能,但存在金屬集流體的腐蝕問題。Through the comparison between freeze - drying and heat - drying, the agglomeration and the desorption of the precursor on carbon support can be alleviated with freeze - drying method. the effects on the electrocatalysts by pretreatments of carbon support, dispersant and precursor are studied. the result shows that pretreatment of the carbon support by kmno _ 4 can add oxygen - containing functional groups on the surface of carbon, which can reduce the hydrophobicity of the carbon support, and then make it much easier for carbon to dissolve in water to form suspension ; isopropyl alcohol can make the carbon support in high dispersion in the precursor solution, which can make the precursor absorbed on the surface of the carbon
採用高錳酸鉀氧化預處理的碳載體比表面積較大,表面含氧官能團數量較多,親水性較好,有利於前軀體在碳載體表面的吸附;選取異丙醇作為預凍液中的分散劑,有利於碳載體在前軀體溶液中的分散,容易實現前軀體離子在碳載體表面的穩定吸附和分散;使用酸性pt ( no _ 2 ) _ 2 ( nh _ 3 ) _ 2作為前軀體,可以使前軀體離子和碳載體表面的酸性含氧官能團發生離子交換反應,使得前軀體離子吸附量增大,分散更加均勻,以上三種因素的選取都可以得到催化活性更高的pt / c催化劑。Abstract : several basic problems with the trace elements in cast irons which was studied by using thermodynamical theory was intorduced. these problems included : the solubility of trace elements in cast irons, the influences of trace elements on the crystallization temperature of molten irons, and the tendency to form carbide in molten cast irons
