某蒸汽动力厂按一级再热理想循环工作，新蒸汽参数为p1=15MPa，t1=600℃，再热压力pA=1.4MPa，再热温度tR=t1=600℃，背压p2=0.005MPa。功率为150000kW。试求：①定性画出循环的T-s图；②求循环热效率；③每小时所需蒸汽量。
蒸汽的有关参数如下：
| p/MPa | t/℃ | h/(kJ/kg) | s/[kJ/(kg·K)] |
| 15 | 600 | 3582.3 | 6.6776 |
| I.4 | 2892.84 | 6.6776 | |
| 1.4 | 600 | 3694.8 | 7.8710 |
| 0.005 | 2401.11 | 7.8710 | |
| 15 | 152.89 | 0.4762 |
饱和水的性质：
p/MPa h'/(kJ/kg) s'/[kJ/(kg·K)]
0.005 137.89 0.4762
有一位置随动系统，结构图如图3-5所示。K=40，τ=0.1。(1)求系统的开环和闭环极点；(2)当输入量R(s)为单位阶跃函数时，求系统的自然振荡角频率ωn，阻尼比f和系统的动态性能指标tr，ts，σ%。
一个垄断者如具有下列长期总成本和总收益曲线：
π＝0.01Q2+12Q
TR＝-0.04Q2+22Q
当最高价格分别为P＝15和P＝16时，它的利润最大化时的产量在前一价格和后一价格时相等。( )
