The experimental results proved that with the input of the limestone the yield of tar decreased and the yield of gas increased and the quality of the gas was also improved.

结果表明，石灰石的加入降低了焦油产率，提高了煤气产率，改善了煤气质量。

Calcium oxide in circulating ash is favorable to decrease the yield of tar and increase the yield of gas in partial coal gasification process with the circulating fluidized bed technology.

在以循环床锅炉循环灰为热载体、部分气化产生的半焦为锅炉燃料的煤的部分气化技术中，循环灰中的氧化钙对降低焦油产率、提高煤气产率是有利的。

Being able to fluidize includes the kinetics of the deposition of the gas, in our case silane, which is important for yield, because unconverted silane lowers your granular poly yield.

我们制造硅烷的能够流体化包括了气体的沉积动力学，这对产量的重要，因为会降低你的未转换的颗粒聚硅烷产量。

Such wells yield plenty of gas as a by-product.

ECONOMIST: Shale gas is giving a big boost to America��s economy

Woodada drilled ahead to become a successful conventional gas producer, while those shales of 33 years ago are only now starting to yield the gas which has been trapped and ignored for millions of years.
