A mathematical model for the reversible exchange of THO between the sieve tube lumen and its surrounding phloem tissue is used to explain the difference between the apparent velocities of THO and (14)C-sucrose transport observed when both are supplied simultaneously. Theoretically predicted results show a close correlation with those obtained experimentally. This model may be used in evaluating previous work in which THO was used as a tracer. The calculations support the existence of a mass flow of sugars in aqueous solution along the path.
利用一个用于描述氚代水（THO）在筛管腔与其周围韧皮部组织之间可逆交换的数学模型，来解释当同时供应THO和¹⁴C-蔗糖时所观察到的它们表观运输速度的差异。理论预测结果与实验所得结果密切相关。该模型可用于评估以往将THO用作示踪剂的研究工作。这些计算结果支持了糖在水溶液中沿该路径进行质量流运输的存在。
