漓江上游防洪水库对桂林市区河段洪水组合影响分析

Though the situation is very hard, EAMP is confronting many opportunities: First, with the combination of upper state-owned fertilizer manufacturing firms, EAMP can control upstream manufactures with very low cost;

虽然经营环境恶劣，但农资企业仍面临着相当多的机会：一是上游国有化肥生产企业改制重组，出现了低成本控制上游生产的绝佳机会；

It can insulate the upstream and downstream flow field resulting in the noise drop of the text section from the downstream and can control the Mach number exactly in the transonic state.

它在跨声速状态下具有隔离上下游流场从而降低试验段噪声，精确控制马赫数的作用。

The paper also constructed iterative steps of signal control strategy in oversaturated trunk roads, detailed design signal coordination control method for the traffic bottlenecks upstream, downstream respectively, including the start and end conditions of the signal control, signal timing adjustment method.

论文还构建了过饱和干道信号控制策略的迭代步骤，分别对交通瓶颈上游、下游实施的信号协调控制方法进行了详细设计，包括信号控制的启动与结束条件、信号配时调整方法。
