It is shown that the course of decline of milk secretion with the advance of the period of lactation may be expressed by the equation of a monomolecular chemical reaction; that is, the percentage decline of milk secretion with the advance of the stage of lactation is constant. This substantiates the idea that milk secretion is limited by a chemical reaction, and, in general, brings lactation into the class of processes the speed of which is determined by the concentration of a limiting substance.
研究表明,随着哺乳期的推进,乳汁分泌的下降过程可以用单分子化学反应方程来表示;也就是说,乳汁分泌的百分比下降与哺乳期的阶段推进是恒定的。这证实了乳汁分泌受化学反应限制的观点,并且通常将哺乳归入由限制物质浓度决定速度的过程类别。
