| 6. | For the pipe section with natural gas hydrates formed , several effective methods to treat ngh are suggested to use , that is , depressurizing as fast as possible ; heating the pipe ; injecting methanol / ethylene glycol and venting
指出对已形成水化物的管道段，可采取尽快降低运行压力、加热、注醇和放空等措施进行处理。 |
| 7. | When the crossing angle is larger than 90 degree , the pipeline would prone to suffer a buckling damage ; ( 2 ) it cannot be used to analyze the large deformation in the pipe section
现有的壳模型有限元方法虽然可以分析管截面中的大变形情况，但是，由于在断层作用下受影响的管子的范围比较长，需要耗费大量的计算时间。 |

| 9. | The study result also shows that there is significant energy exchange between all the pipe sections connected to the same junction , therefore , those flow phenomenon can not be accurately reflected if neglecting or adopting the constant energy loss coefficients
研究结果还表明，与同一结点相接的各管段间存在显著的能量交换，因此，忽略或采用恒定不变的能量损失系数均不能正确地反映这些水流现象。 |
| 10. | The simulation shows that the valve throttle area should be little as possible but must be more than 40 % of pipe section area ; when the total length of pipe is same , and the flow quantity is enough , pipe before primary valve should be thin and long , and the pipe after primary valve should be thick and short , the upriver and downriver small pressure fluctuation will badly lead to waterdrammer pressure rising , and spending more time in establishing pressure and flow quantity
仿真表明,阀门过流面积在满足大于管道截面积40 %的条件下应尽可能小;在管道总长一定并满足流量要求的条件下,主阀前应采取长而细的管道,阀后则应采用短而粗的管道;上下游微小的压力波动都会严重增大开关阀门引起的水击,并使压力、流量的建立需要更长的时间。 |
