This is also called normalization or standardization. It is the procedure of multiplying an appropriate number (called a normalization constant) in an abstract vector space so that the magnitude of a vector (called the norm) becomes 1. In quantum mechanics, the behavior of a single particle is often expressed as a wave function Ψ ( x , y , z , t ), in which case | Ψ ( x , y , z , t ) | 2 dxdydz is proportional to the probability of finding the particle within the infinitesimal region dxdydz at the position ( x , y , z ) at time t . Therefore, the integral of this probability over the entire space is [Koide Shoichiro] [Reference] |Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
正規化、規準化ともいう。抽象的なベクトル空間でベクトルの大きさ(ノルムとよぶ)を1にするように適当な数(規格化定数という)を掛ける手続をいう。量子力学では、1個の粒子のふるまいを波動関数Ψ(x,y,z,t)で表すことが多いが、その場合|Ψ(x,y,z,t)|2dxdydzは、時刻tにその粒子を位置(x,y,z)のところの微小領域dxdydz内にみいだす確率に比例する。そこでこの確率を全空間で積分したもの [小出昭一郎] [参照項目] |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
