The hypersonic velocity of the flame shortens the time of interaction between the powder and flame, while the low temperature of flame limits the grain growth and decomposition of coating.

火焰的高超声速速度缩短了粉末与火焰之间的相互作用时间，而火焰也促使了颗粒增长和涂层分解的低温限制。

If one can meditate on a flame, grain of rice or other subject, why not meditate on the posture one is performing?

如果你能对一个火焰，一个米粒或者其它物质进行冥想，为什么不能在你正在做的一个体式冥想呢？

There is something that one might be able to hold on to: the knob of something, the little flame of something that ; The grain of sand. -The grain of sand; but there is really not a decent metaphor for it, I think.

一个你可以依靠的支点：,一个不同寻常的想法，一个思想的小火花,就像一粒沙中看世界，-一粒沙中看世界;,不过我认为任何比喻都不够贴切。
