摘要
ＫａｒｏＬｙｈａｚｙ模糊空时度规的平均效应相当于宇宙引力辐射背景．甚早期宇宙的基本粒子模型预言目前这种背景辐射的温度约为１°，这给模糊空时度规以一定限制．另外，当考虑粒子在弱但并非稳态的引力场中的缓慢运动时，测地线方程的近似形式为ｄ２ｘｊ／ｄｔ２≈１２ηｉｊ（ｇ００／ｘｉ－２ｇｏｉ／ｘ０），而非ｄ２ｘｊ／ｄｔ２≈１２ηｉｊｇ００／ｘｉ．因而Ｄｉｏｓｉ和Ｌｕｋａｃｓ对ＫａｒｏＬｙｈａｚｙ模糊空时中运动带电粒子发出的电磁辐射的计算应当修正．结果表明ＫａｒｏＬｙｈａｚｙ模型可以不违背通常的实验事实．
The average of the metric of Karolyhazy hazy space time should correspond to the cosmic gravitational radiation background.The elementary particle model of the very early universe predicts that the present gravitational radiation background temparature is about 1°K,which gives the hazy space time metric a certain restriction.Moveover,when consider the case of a particle moving slowly in a weak but not stationary gravitational field,the approximate form of the geodesic equation is d 2 x j d t 2≈12η ij g 00 x i-2g oi x 0 but not d 2x i ≈12η ij g 00 x i .As a result,the Diosi and Lukacs's calculations of electromagnetic radiation prom Karolyhazy hazy space time should be corrected.The result shows that Karolyhazy hazy space time model does not necessarily contradict common expsrimental situations.
