Here is our accumulator which has that nitrogen overpressure which upon loss of pressure in the core would automatically insert coolant into the core should there be a break.

这是我们的蓄电池，那已经氮过度增压，面临着在核心里压力的损失，那会自动的加入冷却剂到，核心去，然后就会产生一个破裂。

The influences of the aspect ratio and wall roughness on the coolant flow characteristics, which mainly involve pressure loss, secondary flow and turbulence intensity, were investigated.

研究了高宽比和壁面粗糙度对压力损失、二次流动和紊流强度的影响。
