这句话该怎么表述呢？

Results indicate that minimizing the time needed to clear the PME thruster surface of the residual, low density and pressure ‘spent’ air plasma (i.e., generated during LSD wave propagation across this surface), and its subsequent decay, is critical for maximum PME engine performance.
大概意思是：结果表明：最大限度地减小PME推进器表面残余的、低密度和压强的空气等离子体所需的时间（即LSD在表面传播时产生的），和它随后的衰减，对提高PME发动机性能是很关键的。或者……
这句话该怎么表述呢？谢谢。

？？？

如何表述成通顺、完整、意思明确的句子？谢谢。

自己慢慢推敲吧。英文翻译，搞的好很费事的。

Results indicate that minimizing the time needed to clear the PME thruster surface of the residual, low density and pressure ‘spent’ air plasma (i.e., generated during LSD wave propagation across this surface), and its subsequent decay, is critical for maximum PME engine performance.
最大限度减少清除PME推进器表面残留的、低密度和低压强的已失去效能的空气等离子体（即LSD在表面传播时产生的等离子体）及随后等离子体的衰减所需要的时间，对于提高PME发动机的性能至关重要。
请问这样是不是合适？谢谢。
