4、据＝150cm，＝125m，＝40cm，=3m/s，试计算阀门的值。解：由已知条件可得：Thegeneralstaff(1employeesinadditiontovicepresident,director,manager,deputymanagerandspecialpositionsoutsidethecontractperiod)toresign,togive10daysnotice,theprojectmanagerordepartmentmanager,administrativepersonneldepartmentorrelevantresponsibl

7、成不同的区域。③如果已知某一控制水深，即可在相应的流区内定出其水面曲线的类型。④分析水面曲线两端的界限情况，便可确定水面曲线形状。分析结果如下列图所示：Thegeneralstaff(1employeesinadditiontovicepresident,director,manager,deputymanagerandspecialpositionsoutsidethecontractperiod)toresign,togive10daysnotice,theprojectmanagerordepartmentmanager,admin
