是的，巨大的冰块可以“击沉”泰坦尼克号，但是你能想象用冰块制造军舰吗？这并不是个荒唐的想法，第二次世界大战的困境激发了英国人的想象力，他们完成了“冰航母”（Iceberg-Ship）的图纸，制作了模型...

第六部分. 结论本文主要介绍了NVM的发展过程和技术概况。主要的编程手段有热载流子注入和FN隧道效应。在FN隧道效应中，门极氧化层厚度一般小于12nm，而在热电子注入中可以厚很多。两种典型的擦除机制为...

明白了，感谢您的解答！DDS的频率解析度倒是很高，但总觉得感应加热的频率随工件变化需要有自适应的能力，当然通过I/U相位的反馈，进过MPU处理也可以做到准实时跟踪。PLL闭环电路，可以迅速跟踪到合适的...
