求翻译：当毛细管系统的供热（冷）能力确定时，水流量也随即确定，我们的目标函数是使比摩阻最小，同时管材用量和保温材料用量最省，而这两者均与管径有关[8]。是什么意思？

When capillary tube system for the hot (or cold) Ability to determine when water flow, and then determines the target function, we are more than the minimum, Moses blocked tubes usage and keep warm while material usage the most provinces, and the two are related to pipe diameter [ 8].

When capillary vessel system heating (cold) ability determination, the discharge of water also immediately determined that, our objective function is causes the frictional resistance to be smaller than, simultaneously the tubing amount used and the thermal insulation material amount used most saves,

When the capillary system of heating (cooling) OK, water flow is determined, our objective is to make more than minimal friction, also using pipes and insulation material in most, which is related to the diameter [8].
