如果你的前景指的是找工作，那很难说。
power elec 就挺promising。
没人能肯定的预测未来，就像nano，一旦产业化，就基本替代了现在的semi，应该算有
前景了巴，可谁知道他是5年，10年，还是50年才能产业化。
98-00最有前景的optical, 01-04是死的最惨的。
目前power, rf都比较hot, 但谁能说以后5年会不会和当年的optical一个结局。

日本Micronics Japan公司与Guala Technology公司（总部：神户市）共同开发
出了新原理充电电池“battenice”的量产技术。这种电池不同于化学电池，而属于采
用量子技术的物理电池。用两节串联的5号干电池给试制的100mm见方、厚11μm的片状
电池充电大约1分钟，就可供小型马达驱动风扇1分钟以上。并且，风扇的转速基本为定
数，放电特性象化学电池那样可保持一定的电压，而不是象双电层电容器那样电压会随
着放电成比例下降。
Micronics Japan公司认为，battenice可实现1.5V电压，500Wh/L能量密度，
8000W/L的输出功率密度，充放电寿命（维持在初期容量的90％以上时）为10万次
，工作温度范围-25～+85℃。试制品采用厚10μm的不锈钢箔作基板，只在基板的一面
形成了电池层，今后将考虑采用更薄更轻的铝箔作基板并在基板两面形成电池层来实现
上述目标。
这种新型电池是采用由绝缘膜（绝缘性树脂或无机绝缘物）包裹的n型金属氧化物

发帖数: 808 | 39 【讨论】扫描电子显微镜的设计思想和工作原理
扫描电子显微镜的设计思想和工作原理，早在1935年便已被提出来了。1942年，英国首
先制成一台实验室用的扫描电镜，但由于成像的分辨率很差，照相时间太长，所以实用
价值不大。经过各国科学工作者的努力，尤其是随着电子工业技术水平的不断发展，到
1956年开始生产商品扫描电镜。近数十年来，扫描电镜已广泛地应用在生物学、医学、
冶金学等学科的领域中，促进了各有关学科的发展。
一．扫描电镜的特点
和光学显微镜及透射电镜相比，扫描电镜具有以下特点：
(一) 能够直接观察样品表面的结构，样品的尺寸可大至120mm×80mm×50mm。
(二) 样品制备过程简单，不用切成薄片。
(三) 样品可以在样品室中作三度空间的平移和旋转，因此，可以从各种角度对样品进
行观察。
(四) 景深大，图象富有立体感。扫描电镜的景深较光学显微镜大几百倍，比透射电镜
大几十倍。
(五) 图象的放大范围广，分辨率也比较高。可放大十几倍到几十万倍，它基本上包括
了从放大镜、光学显微镜直到透射电镜的放大范围。分辨率介于光学显微镜与透射电镜
之间，可达3nm。
(六) 电子束对样品的损... 阅读全帖 |

反观Honda，既然出了RDX，又不敢以运动性正面和欧洲车抗衡，那就只能回到价格便宜
