求翻译：活动和节点的最迟时间采用逆推法（Backward Pass）计算，逆推法（Backward Pass）一般从项目的最后一个活动开始计算，直到计算到第一个节点的时间为止，在逆推法的计算中，首先令最后一个节点的最迟时间等于其最早时间，然后开始计算，具体的计算步骤如下所示：是什么意思？

Of activities and no later than the time of the node using the backward method (backward pass), backward (backward pass) is generally calculated from the last activity of the project, until the time calculated to the first node in the backward method of calculation the latest time of the last node,

Activities and nodes in the latest time reverse the law (Backward Pass) computing, reverse the law (Backward Pass) in general, from the final project a start of the event, until the first node of the time, so far in reverse the law of the calculation, you first make a node in the latest time is equa

Active and the node latest time uses counter pushes the law (Backward Pass) to calculate, counter pushes the law (Backward Pass) to start from the project last activity to calculate generally, until calculates the first node the time, in counter pushes method in the computation, first makes the last

Activities and node of most late time used inverse push method (Backward Pass) calculation, inverse push method (Backward Pass) General from project of last a activities began calculation, until calculation to first a node of time weizhi, in inverse push method of calculation in the, first order las
