但是他希望，通过在纳米管的表面更平均地沉淀铜纳米颗粒，结合其他一些改进，他们能够提高转化速率上千倍。

But he hopes that depositing copper nanoparticles more evenly onto the surfaces of the nanotubes and making other improvements will help boost their conversion rates by a factor of several thousand.

比如探究气泡生长速率如何随气泡面的数目变化而变化，以及单位容量内使表面积最小化。

Those include uncovering how bubble growth rates vary with the number of bubble sides and minimizing the surface area per unit volume.

当腐蚀浸泡的时间大于120分钟后，腐蚀产物在铝合金表面产生了明显的位阻作用，从而使腐蚀速率逐渐下降，直至48小时后，腐蚀速率趋于一相对稳定的数值。

Because of the place obstruction of corrosion products in the surface of the alloys, while corrosion time is at 120 minutes above, the corrosion rate descends to the stable value in 48 hours.
