， 就叫我用beclomethasone dipropionate， 二丙酸倍氯米松， 一个月用处不是很大
，就 叫我动手术，
Radiofrequency Turbinate Reduction (XXXplasty)?微波
用微波烧把鼻甲烧小点， 他看来似乎做了挺多的， 说是没啥风险， 有没有有经验的？
这个医生诊断时间非常短， 大概看看， 非常之潦草， 我觉得我的炎症可能是鼻窦的，
和耳朵相连
如果仅仅是缩小鼻甲， 鼻窦炎症本身没有消除， 是不是治标不治本？
我问了老妈她以前是医生， 她说如果是息肉做没问题，
如果鼻甲肥大，会不会导致以后有鼻甲萎缩现象发生， 她也是踢地疑问， 毕竟不是5关
克的
我想在这里问问这方面的信息， 非常感谢

发帖数: 32207 | 21 概念车我印象里有，或者说hobbiist的原型车
near-commercial的没见过
主要的问题，以前也讨论过，就是gas-turbine的经济工况比较窄
换句话说如果不在接近峰值功率的状态工作就太费油
但如果一直在这个工况工作的话，反过来路上消耗的功率没那么多
那剩余功率怎么处理就是个问题
电池的话也没那么大容量好用
船上对这个问题的解决方法似乎是用多台中等功率的燃气轮机
然后根据需要功率不同开不同的台数，来控制总输出功率同时保证经济性
但车上这个就过于复杂了。空间上也不容易解决。 |
