1)  basic electrode
碱性药皮焊条
2)  basic covering
碱性焊条药皮
3)  coating basicity of electrode
焊条药皮碱度
1.
The results reveal that,with the increase of coating basicity of electrode,the sulphide inclusions formed in welding pool changed from a small size sulphide,such as MnS,MnFeS,into a large size compound inclusion,which encircled the periphery of compound oxidate.
结果表明:随着药皮碱度增加,在熔池中形成的硫化物夹杂从细小单独的硫化物,如MnS、(MnFe)S等,变成硫化物包裹在尺寸较大、易于浮出的复合氧化物周围,从而有利于熔池内部的脱硫;硫在熔渣-铁水间的分配系数Ls与焊条药皮碱度B1的关系呈极大值的抛物线状;熔敷金属的含硫量ω(S)与焊条药皮碱度B1的关系为有极小值的抛物线状。

补充资料:透皮给药系统
分子式:
CAS号:

性质:是一种经皮肤给药的制剂。组成:以硝酸甘油为例,背膜是不透药液的涂铝塑料,中间为药液储库,硝酸甘油吸附在乳糖,胶状二氧化硅上,药液储库的下侧复以控释膜,其表面有一层贴在皮肤上的黏合剂,粘贴皮肤不应引起过敏反应,粘贴层外面有一层铝膜覆盖,在使用时撕去。透皮剂型的优点:避免口服药物在消化道中遇酸酶破坏或食物吸附及消化道功能的影响;无首过代谢;无注射给药的不便;一次用药代替几次用药;药物储库释放持久使半衰期短的药物的药效明显延长;可任意终止给药。透皮剂型的缺点为对皮肤有刺激性或过敏反应;有耐受现象;制作工艺困难,价格昂贵。
