41. Excited states are formed in a glow discharge in a chamber through which the gas flows . 42. The amount of gas flow into the apparatus is measured and maintained through a flow meter. 43. It is a similar method for relating the reactant gas flow rate to the reactor volume. 44. The gas flow past the rough sand castings could be greatly improved by polishing the passages. 45. Gas flow through these small holes allows the engines to use higher temperatures than otherwise possible.46. In addition to the power source, the type of gas flow can affect performance as well. 47. The trick is getting the right water and gas flows to optimize how much gas is absorbed. 48. The gas flows and stops intermittently and the wave continues on to the end of the pipe. 49. Three pipeline projects will give Russian companies more say over oil and gas flows in the region. 50. The resulting film morphology can be tuned by changing the gas flow rate and the source temperature.
