常見例句雙語例句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.定步長的缺點在于不管是積分曲線的各個點的曲率如何都取一樣的步長，這樣肯定會在曲率大的一些點帶來比較嚴重的誤差，這種誤差將在每一步的計算中積累。 返回 accumulation curve
