With the carbon content of dry ash-free basis increasing, ignition activationenergy increases and reaction rate falls.
干燥无灰基固定碳含量增加，着火活化能增加，反应速率减小。
2
Te-free memory material with adjustable crystallization temperature, melting point and crystallization activationenergy can be obtained by changing the ratio of the two compositions.
通过调整这种材料中两种元素的组份，可以得到具有不同结晶温度、熔点和结晶激活能的存储材料。

The free radicals can make spontaneous combustion activationenergy of diesel fuel reduced greatly and shorten the ignition delay period, and thus improve the combustion performance of diesel engine.
