双语例句
- The results indicate that the electric field can induce the instability of dielectric liquid and condensating film on the tube wall with bead or quasi-bead, at the same time the electric field also can cause turbulence in gas fluid and result in heat transfer enhancement.
结果表明：电场会引起介电流体的不稳定性，导致管壁膜状凝结转变为珠状或准珠状凝结；电场也可引起场域空间气体的紊流并导致换热的增强。
