The fourth chapter analysesthe differences of the resistance between the boundariescalculated by different models.It can seen from the results thatthe differences between resistances calculated by variousfunctions can ignored under unstable conditions.There areobvious differences between different resistances calculated bydifferent functions under stable conditions.However,in bothcases,error from any function to predict transpiration rate isignoble.In order to make more applicable,the Monteith modelwas fished in this chapter.

第四章分析了各种边界层阻力计算模型计算结果的差异，比较结果表明，在空气层结不稳定时，各种φm函数经验模型计算阻力的差异可忽略，而当空气层结稳定时各种φm函数经验模型所算边界层阻力有明显差异，但不论是稳定和非稳定层结下，任选一中φm函数计算模型对蒸腾速率计算结果所造成的差异可忽略，为便于应用，本章还比较和检验了Monteith模型计算结果的差异，结果表明，该模型用于蒸腾计算，其误差可忽略不计。

The paper carries out mechanical analysis of the weight distributing of goods in loading container based on analysis of packing and tansporting environment, and draws the formula of the ratio of the weight of loading goods and the maximum loading weight W/W0, and the length distributing ratio of loading goods α=l/L under the condition that the bending quadrature produced by part load is within the range of the maximum bending quadrature. It also gives the graph that the sum deflection of mudsill and underside girder can reach high-point value with the length of bottom distributing varying, when the loading amounts of container of 20ft and 40ft are given. Furthermore, it provides the relation graph of an eccentric rate of loading goods and the allowed loading amount. For on-site safety loading work, it has certain guidance and reference value.
