At the same time i also did many primary experments on separator and these polymer membrane can be used in as soft packaging li - ion battery ’ s separator. used polyvinylidene fluoride ( pvdf ) as the basic material, added cotton fibre and starch in, cooked with 100 in boiling water afer 3 hours, the starch inflate, and then acquire porous polymer membrane. in the process of coating polyester film, copper foil and aluminum boil were used to as carrier,
選用的基體材料為pvdf ，同時向其中添加棉纖維和澱粉，最後利用100沸水對隔膜進行3小時蒸煮處理使澱粉溶脹，從而達到造孔的目的。在塗布工藝的篩選中，通過對麥臘片、銅箔、鋁箔進行篩選，最後選定以銅箔為載體來進行塗布處理。當以銅箔為載體時，可以使隔膜正反兩面物理性質達到基本一致。 -
He explains why microwaves cook fish well and meat poorly ( they heat only water molecules, and those to just below boiling : in other words, they poach, producing succulent fish but bland meat ) ; why one should dress a salad just before serving ( oil penetrates the thin waxy cuticle that coats vegetables, driving out the air that refracts light and gives vegetables their colour ) ; why potatoes are the perfect food to deep - fry ( a wealth of starch and sugar on the surface ) ; and why the easiest way to salvage curdled mayonnaise is to wait until the oil separates completely, then just pour it back in, whisking constantly
他解釋了很多廚房內的問題，為什麼用微波爐烹飪出的魚味鮮色美，而做出的肉卻難以下咽（微波爐只對水分子有加熱的作用，而加熱的程度僅低於沸點：換言之，這是一種用熱水煮的過程，所以烹飪出的魚會多汁，而肉卻味道一般） ；為什麼僅在上菜之前的那一刻才給沙拉添加拌料（因為油會浸入保護蔬菜的薄弱表層，並迫使蔬菜內含有的對光線有折射作用的空氣，這樣蔬菜就具有了最本質的顏色） ；土豆為什麼通過油炸才味道最佳（因為油炸過程中，大量的澱粉與糖份會浮出到土豆的表面） ；以及為什麼給蛋黃醬解凍的最簡便的方法是先把醬倒出來，等內含的油完全分離之後，然後把醬倒回瓶子里，再不停地攪拌。
