Compared to the untreated sample, the adsorbed carbon atoms can more easily find suitable nucleation sites on the W-implanted substrate so as to be protected from re-evaporation.

与未处理的样品相比，沉积碳更易在W离子注入后的基底表面找到适合的成核生长点，避免被重新蒸发。

The results show that the composite is dense and silicon particles are distributed uniformly. Transmission electron microscope observations show that stacking faults with high density, twins and dislocations are found in silicon particles. The Si-Al interfaces are well-bonded and no interface reactants are found. The dislocations and eutectic silicon precipitates are observed in LD11 matrix. Sip/LD11 composite has low density of 2.4 g/cm3, low coefficient of thermal expansion of 8.1×10-6/K, high thermal conductivity of 161.3 W/, and the annealing treatment can reduce the CTE and improve the thermal conductivity.

研究结果表明：复合材料组织致密，颗粒分布均匀；透射电镜观察发现，在Si颗粒内部存在高密度的层错，同时还存在孪晶和位错； Si-Al界面结合状况良好，无界面反应物； LD11铝合金中存在位错和析出的共晶Si；复合材料具有低密度(2.4 g/cm3)，低热膨胀系数(8.1×10-6/K)，高热导率161.3 W/(m·K的特性，可以通过退火处理进一步降低其热膨胀系数，提高热导率。

In 1952, W. Ross Ashby, a cybernetician interested in how machines could learn, wrote," does not specify in detail how a kitten shall catch a mouse, but provides a learning mechanism and a tendency to play, so that it is the mouse which teaches the kitten the finer points of how to catch mice."

1952年，关注机器如何学习的控制论专家W罗斯艾希比（2）写道：&并没有具体规定小猫如何抓老鼠，但是提供了学习机制和游戏的旨趣，因此是老鼠将捕鼠的要领教给了小猫。&

I didn't watch TV last night, because it .
