查询词典 diffusive

According to the experimental results, both the conducting area and material of current collector slices have great influence on the performance of micro PEMFC, especially the former one. The increment of cell's performance is finite by increasing the gas reheats temperature. The performance is better for open ratio 75% compared with 50% and 67%. The concentration polarization is improved by increasing the air flow rate at high current density and if the GDL diffusive capability in the latter cell could be promoted, the differences between these two cells' performances would be reduced.

由实验结果可知，集电片的导电面积与材料对於电池性能有显著的影响，尤其是前者；对於增加反应气体的再热温度，微型燃料电池增加的性能有限；双极板开孔率75%相较於开孔率为50%与67%有最佳的性能曲线；增加阴极气体空气的流量，可以改善高电流情况下的浓度极化现象，所以若我们能增加气体扩散层的扩散能力，则可以减少两者的性能差距。

Besides, the data of n observed at perigees are used to roughly estimate the altitudes of the turbopause Zt and their variations according the two distinct vertical distributions of atmospheric composition in low and upper atmospheres: the homogeneous mixing and the diffusive separation.

采用近地点上的n观测资料，根据大气数密度在低层内均匀混合和高层内扩散分离的不同垂直分布特征，粗略地估算出湍流层顶的高度Zt及其变化。

The previous study indicated that the deposition rhythm of the daily growth incrementsin otoliths of the fishes will be diffusive during metamorphosis.

过去研究认为鳗鱼在变态过程中耳石的日周轮会消失，而且变态时耳石的微细构造和微化学会产生急遽改变。

Based on the diffusive equation of incoherent-feedback random lasers,whose gain is modified by adding a saturation factor,the evolution of the emitted light intensity in two-photon pumping random lasers varying with time is studied by use of finite difference method.

引言从20世纪90年代开始，人们对光在增益无序介质中与介质相互作用而产生的受激辐射现象的研究表现出了极大的兴趣[1—11]。实验上，国内外的学者们在不同的随机介质中观测到了光的放大。

Parallel glide appears to be a consequence of constrained diffusional creep, which involves a diffusive exchange of atoms between the unpassivated film surface and the grain boundaries at high temperatures.

平行滑动看起来是一个强制的diffusional的结果爬去，在高温下与一次在unpassivated 电影表面和粮食边界之间的原子的散播的交换有关。

During incubations, significant uptake fluxes of NO(superscript - subscript 3) and SiO(superscript 2- subscript 3) were commonly shown at the sediment-water interface, and largely controlled by their concentrations in the overlying water. The molecule diffusive fluxes, calculated from the concentration gradients between overlying water and surface pore water, seemed not so important in the exchange fluxes.

沉积物－水界面交换过程在春季表现为对NO(上标-下标 3)和SiO(上标 2-下标 3)的吸收，吸收的量在很大程度上取决于上覆水中这两种营养盐的浓度；由上覆水和表层间隙水浓度梯度所决定的分子扩散通量对实际交换通量的控制有限。

Conventional HD is diffusive; blood is circulated in an artificial kidney machine on one side of a semi-permeable membrane, while a special dialysis fluid is circulated on the other side.

常规HD是扩散；血液中散发的人工肾机一方的半透膜，而透析液特别是散发的另一边。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
