reaction entropyとは 意味・読み方・使い方

The secondary battery has a combination of an anode active material and a cathode active material having an area in which an entropy variation ΔS of the total battery reaction under a normal temperature atmospheric pressure becomes endothermic.例文帳に追加

前記二次電池は、常温大気圧下における全電池反応のエントロピー変化ΔＳが吸熱となる領域を持つ負極活物質と正極活物質の組み合わせを有する。 - 特許庁

An explosive dehydration-condensation reaction is induced by rapidly releasing pressure of a mixed composition of a polyvinyl alcohol-based polymer and a polysaccharide from a high temperature and pressure state in which water has remarkably high entropy to normal pressure in a thin film state in the presence of water, thus leading to a dehydration reaction between hydroxy groups of the polysaccharide and the polyvinyl alcohol-based polymer which does not occur normally.例文帳に追加

ポリビニルアルコール系重合体と多糖類との混合組成物を水の存在下、水のエントロピーが著しく大きい高温高圧状態から薄膜状で急激に常圧に解放することにより、爆発的な脱水縮合反応を生起させ、通常では生起しない多糖類とポリビニルアルコール系重合体のヒドロキシル基の脱水反応を生起させる。 - 特許庁
