扩散激活 meaning in English
spreading activation
Examples
- Computation of diffusion activation energies of c , n in fe
中扩散激活能的计算 - The activation energy of the tpl peak is calculated being about 1 . 5 ev for four heat treated samples ( furnace cooling , air cooling , dry ice quenching , liquid nitrogen quenching ) , and it is near the self diffuse activation energy of aluminum 1 . 45ev
炉冷、空冷、干冰冷和液氮冷四种热处理制度根据几，峰峰温数据计算的激活能的结果约为1 ? sev ，接近于铝的自扩散激活能1 . 45ev 。 - Sc shows no diffusion during heated between 800 ? to 1290 ? . analysis the result of all the experiments above , we can know porous matrix , nanometer re oxide particles and fine crystal structure can accelerate the active matter diffusion to the surface , and do good effect to the emission performance of cathode
阴极表面的空隙有利于活性物质的扩散；纳米尺度的稀土氧化物自身能量高，易于克服扩散激活能而进行扩散；发射过程中阴极表面的微晶化使表层晶界增多，活性物质扩散通道增多，利于扩散进行。 - 4 we use make thin film adsorption desorption model , have studied the particle desorption activation in fecu granular film , energy show with the change relation of fe content in membrane : the desorption activation of particle in fecu granular film can want to spread activation than fe or cu can big near 5 times , particle desorption activation energy value between 3 . 815ev and3 . 858ev increase , with fe content instead of increasing linearly
4 、利用io . h . ro详无eu提出的薄膜吸附脱附模型，研究了fecu颗粒膜中粒子脱附激活能与膜中fe含量的变化关系，表明: fecu颗粒膜中粒子的脱附激活能要比fe或cu的扩散激活能大近5倍，粒子脱附激活能数值在3 ， slsev ~ 3 . 858ev之间，随fe含量增加而非线性地增大。
