纵向扩散的英文
longitudinal diffusion
例句与用法
- By integrating the backmixing theory of reaction engineering with predictive model of river pollution in environmental quality assessment study , the predictively longitudinal dispersion model of river quality was got and analyzed
摘要将反应工程学的返混理论与环境质量评价学的河水污染预测模型结合，得出了河流水质预测纵向扩散模型，并给出了解析解。 - The more is diffusion resistance , the less the oxygen quantity is . the even degree going through the diffusion layer and hydrophobic layer depends on relative change of diffusion resistance in crosswise and lengthways . if the diffusion resistance in crosswise is bigger , it will not benefit the oxygen distribution
传输阻力越大，通过扩散层和疏水层氧气的传输量越小，扩散层和疏水层对氧气的均匀化程度取决于其对氧气横向和纵向扩散阻力的相对大小变化，横向扩散阻力大，不利于气体的均匀化。 - In order to increase the energy dissipation of stepped spillway at iarge unit discharge , the integhty dissipater of aerated splitter pier and steppe characteristics is studied . because of verticaj diffhaion now by aerated splitter and impachng steppe 3 by drop flow , the air concentration and the energy dissipation efficiency are greatly increased ; the potentiality of cavitations is decrease . in special at large unit discharge , this effect is more obvious
掺气分流墩的增加，明显地改善了阶梯面上的压强分布，消除或减小了阶梯凹角内和立面上部的负压；由于掺气分流墩使水流纵向扩散以及挑流落下后在阶梯上的撞击，使水流的掺气浓度和消能率都得到较大的提高，降低了阶梯面空蚀的可能性，特别是在大单宽流量时，这种效果更为明显。
