By analysing varied factor and action force of the coke-handspike, this paper pointed the main factor and put forward opinion of reducing the level tolerance in order to reduce vibration.

分析推焦杆推焦中的各种因素及受力情况，找出主要因素，减小水平度公差，减小震动。

Then peak index, kurtosis index, impulsion index and tolerance index of the vibration signal are calculated. These parameters represent the characteristic of failures.

随后计算出代表故障特征的振动信号的峰值指标、峭度指标、脉冲指标和裕度指标等参数。

Seismic pressure gauges for the environment places severe vibration, the pulse of media tolerance, and the impact of a sudden unloading, gauges clear instructions and stability.

耐震压力表适用于环境剧烈振动场所，可耐受介质的脉动，冲击及突然卸荷，仪表指示稳定清晰。
