It is shown that in the growth region (above the critical nucleation size) the transient distributions obtained numerically from the Becker-Döring equation (BDE) by Abyzov et al., , , 558, are in accurate correspondence with the matched asymptotic (singular perturbation) solution by Shneidman, , , 1338. The solution is unmodified by "self-consistency" corrections which affect only the steady state rate. Sensitivity of the results to selection of a specific form of the BDE (the "nucleation model") also is briefly discussed.
结果表明，在生长区域（临界成核尺寸以上），阿比佐夫等人从贝克尔 - 多林方程（BDE）数值得到的瞬态分布与施奈德曼的匹配渐近（奇异摄动）解精确对应。该解不受仅影响稳态速率的“自洽性”修正的影响。还简要讨论了结果对BDE特定形式（“成核模型”）选择的敏感性。
