Thus , solow and other people began to establish the micro foundation of the aggregate product function . this chapter introduces the method of using efficiency distribution to aggregate the micro production function to a macro one and the continuity and integrabel condition of micro production function should meet found by sato 本章着重对加藤( sato ， 1975 )等人应用效率分布的方法实现从微观生产函数到宏观生产函数的加总，以及生产能力密度函数适续性和可积性的条件等研究成果进行了介绍，这些都将成为推导总供给函数和总供给曲线的方法基础。
In fact , this property has been studied in a lot of theses . [ 7 ] , [ 9 ] and [ 10 ] gave some sufficient and necessary conditions of making martingales uniformly integrable , and [ 8 ] gave the special one : the continuous local matingale { xt t r + } is uniformly integrable if and only if this paper gives the sufficient and necessary condition of making sub - martingale uniformly integrable , in addition , derives some sufficient conditions and necessary ones by another way 很多文献也已经就一致可积性的充分必要条件进行了研究，如文献[ 7 ] ， [ 9 ]和[ 10 ]就给出了有关鞅一致可积的充要条件， [ 8 ]对此又进一步讨论，并给出了连续局部鞅{ x _ t ， t r _ + }是一致可积鞅的一个充要条件，即1 = 0 ， (其中) 。
