Methane, oxygen and H_2O molecules are activated, ionized and dissociated into active particles such as CH_3~+, O~-, H_2O~+, CH_3, CH_2, CH, H,OH and O, by nonelastic collision with high energy electrons. The particles react with each other in the reactor to synthesize chemically products including gaseous oxy-hydrocarbons.We study the rule of reaction by changing electrical parameter, gas flow etc. Study the conversion of methane, selectivity of gaseous hydrocarbons and yield of methanol under different reaction condition.

According to the observation experiment at the Jiufeng station where there is smaller environment noise, the conclusions are drawn as follows.In the normal atmosphere, the observed value is about 500×10-5ms-2, which is greater than theoretical value about 30×10-5ms-2, and if in the low vacuum, the observational error about 2.3×10-5ms-2 is generated. The vacuum maintaining system in falling room can not work normally, which will yield 0.1~4.1×10-5ms-2 error to the gravimetric observation. In the case of that the measurement is in the stable geological conditions and the smaller environment noise, the action of vibration isolating spring is not obvious, but it yields greater effects on measurement accuracy.
