发帖数: 40 | 2 我想用石英crystal resonator来做band stop filter. 我们过去用的是LC parallel resonator, 但是我觉得LC resonator品质因子比较低，所以想用效率更高的resonator. 有谁知道有没有共振频率在238 MHz 和900MHz 附近的crystal resonator? 一般来说微调晶体的共振频率是不是要用外

resonance就是叩诊的声音，肺炎的时候是浊音（DULL），气胸是鼓音（hyperresonan

fremitus是你把手掌侧放在病人肺部，让病人深呼吸，感觉到的震颤。pneumonia的时

I did something concerned with getting resonate frequency of
resonator using FDTD,the structure was very simple.But as
far
as I know,you just need to set up Yee's Grid in the
volume,and
use a pulse as excitation,do FDTD in the volume for a time
period long enough until the fields in the resonator get
stable,
then take the field at certain points as sample,do FFT,and
plot
it in frequency domain,you will see the resonate
frequency,which
is determined by the structure of the resonator. |

价钱和性能之间有一个“厂”字形曲线，当然横的那一画是略略上扬的。电钢琴的厂字拐弯大概出现在1000刀出头到2000刀，这是我个人的观点。这是对于新琴而言，二手琴另说。1000刀以下很少能找到我定义下的好琴。我的标准是手感和音色接近钢琴，到一个可以接受的程度。
先说手感。手感对我而言，最少最少也要达到跟yamaha的GH(graded hammer)或者kawai的RH(responsive hammer)同等水平，这已经是最低要求，像GHS就只能算电子琴级别的，我弹完第一个和弦就不想再弹下去。我认为，一上手就能说出的区别，就算巨大的区别了。在GH的基础上再加几百刀，就可以达到GH3。我觉得yamaha的GH3跟kawai的RH是同等级别的，而kawai家CA系列的graded hammer应该更牛。如果再加几百刀能有let-off，这个我也认为值得。BTW，在键的重量问题上，我side by side弹过yamaha家的电钢和声钢，感觉电钢的键比声钢还重，还真是矫枉过正，生怕别人认出它... 阅读全帖 |
