accumulation curve

基本解釋

Dry matter accumulation showed a S curve at a slow-fast-slow rate.
干物質(zhì)積累呈“S”型曲線，符合“慢-快-慢”的增長規(guī)律。
OBJECTIVE To study the fitting about S model dose-effect curve with the accumulation normal distribution function.
目的研究S型劑量效應(yīng)曲線的累積正態(tài)分布函數(shù)擬合。
If the change of step-size is controlled by the value of curvature of integral curve, the result can avoid such an error accumulation.
定步長的缺點(diǎn)在于不管是積分曲線的各個(gè)點(diǎn)的曲率如何都取一樣的步長，這樣肯定會(huì)在曲率大的一些點(diǎn)帶來比較嚴(yán)重的誤差，這種誤差將在每一步的計(jì)算中積累。
