The technique is known as stratospheric aerosol injection (SAI). It is still in its infancy and is yet to be proven.

这项技术被称为平流层气溶胶注入（SAI）。该技术还处于初期阶段，仍有待验证。

Geoengineering would use a technique called stratospheric aerosol injection, or SAI.This would employ aircraft to disperse sulfuric acid or its precursor sulfur dioxide into the upper atmosphere to form.

地球工程将使用一种称为平流层气溶胶注入或 SAI 的技术。这将使用飞机将硫酸或其前体二氧化硫分散到高层大气中形成。
