The rate at which this filtration takes place is known as glomerular filtration rate or GFR.

滤过的速率称为肾小球滤过率，或GFR。

Also this fluid leakage reduces the pressure difference that drives filtration of small molecules and electrolytes like sodium, and so the GFR actually goes down because of the leakage.

此外，这些液体泄漏减小了驱使小分子以及钠等电解质滤过的压力差，因此滤过率由于泄漏而下降。
