A pure and single K+ current of ultrarapid delayed rectifier K+ current or transient outware K+ current is respectively expressed on Xenopus Oocytes. This is a moderm pharmacological model for evaluation class Ⅲ antiarrhythmiv durgs, overcomes many defcts such as lacking human fresh cardiac muscle cells as material and co-expression of many currents on cell membrane. A new compound A1998 from Ocean material is evaluated in this model for class Ⅲ antiarrhythmic functions.

The strong acidity, Fe(superscript 2+) and rather lower concentration of alkalis ions are responsible for voltaite, not jarosite, crystallizing from the acidic iron-bearing water.

分析认为，废液呈强酸性、溶液中存在大量Fe(上标 2+)、碱金属离子含量偏低是蒸发结晶过程中形成绿钾铁矾而不是黄钾铁矾的主要原因。

07 You Will Need: Potassium Nitrata (Salt Peter Found In Garden Shops) Sugar Baking Soda Organic Powderd Dye Mix Potassium And Sugar (60g Potassium to 40g Sugar) Put On A LOW Heat And Stir Sugar Will Start To Caramelise Keep Stirring Untill It Looks... Like Peanut Butter... Add 1 Spoon Of Soda... This Will Slow Combustion... Add 3 Large Spoons Of Dye... And Mix Very Thoroughly... Your Mix Should Look like This Fill A Card Tube With Mix...

你需要：硝酸钾（peter在卖花园用具的商店里买的盐类）糖烘烤用的苏打有机的粉状染料（在兴趣爱好用品商店中有售）混合钾和糖(60克钾兑 40克糖)低温加热，注意搅拌糖会成为焦糖一直搅拌，知道它看起来象花生酱为止加入一勺苏打会产生缓慢的燃烧加入三勺染料最好是橙色或蓝色搅拌均匀你的混合物应该看起来象这个样子 Fill A Card Tube With Mix。。。

It makes the nutrients change from alkalinized form to unalkalinized form .This kind of nutrients remain in the middle layer of soil .
