Normalization of logarithmic normal distribution through mapping transformation 用映射變換將對數(shù)正態(tài)分布正態(tài)化
When the data is not in normal or logarithmic normal distribution , the least - squared method is not applicable to obtaining the sensitive index 若試驗(yàn)數(shù)據(jù)為非正態(tài)或非對數(shù)正態(tài)分布,最小二乘法求優(yōu)會受到限制。
The pearson distribution and the logarithmic normal distribution are used respectively to fit the asymptotic distributions of yearly maximum of the daily precipitation in chengdu during the period between 1951 and 1999 摘要利用1951 ~ 1999年成都日降水量年極大值的記錄,通過統(tǒng)計推斷,找出了成都日降水量年極大值遵循的漸近分布。
4 ) the number and mass concentration distributions of the background atmospheric sand particles of ymchuan , bayanhot and tonggunur display a unimodal form , obeying a logarithmic normal distribution , greatly differing f 黃沙的長距離輸送和小雨是泥雨形成的原因。云物理和降水與來自沙塵粒子混合,尤其是小于zpm的粒子,導(dǎo)致了華北地區(qū)泥雨的發(fā)生。
Abstract : this paper briefly introduces the method of testing the real sensitivity for eed and gives the data processing method in terms of the electrostatic critical ignition energy of conductive - powder eed conforming to logarithmic normal distribution 文摘:簡要介紹了電火工品真實(shí)靜電感度的測試方法,以導(dǎo)電藥式電火工品靜電臨界點(diǎn)火能量服從對數(shù)正態(tài)分布為基礎(chǔ),給出了對應(yīng)的數(shù)據(jù)處理方法。
