Table analyzed.
只显示出table analyzed,那结果在哪里? 如果compute exact statistics for all

PlayStation Move controller lag detected, analyzed, dismissedWhen Sony
unveiled its PlayStation Move (nee Arc) controller at the GDC last week, it
came along with some impressive promises: it would only cost developers 2MB
of system memory (out of 256MB on offer) and it would respond to user inputs
within a single frame of animation. Our own experiences with the thing felt
a bit more laggy, and now Eur |

发帖数: 1781 | 5 今儿我们组里的一哥们遇到一个奇怪的现象：
在query analyzer 里面运行一个query,花了15分钟得到结果，
然后放到把这个query做成一个stored procedure， 除了把where 里面的条件换成了变
量而已，结果需要30分钟才行。
我们的环境是用local的query analyzer 连到 DB server 上。
为什么会有这么大的区别呢？ |

标 题: Anyone uses or knows NH3 analyzer?
发信站: Unknown Space - 未名空间 (Tue Sep 7 17:22:23 2004) WWW-POST
I need to measure NH3 contents within a power plant (fuel source and exhaust).
The measurement range is 0-1000ppm for the fuel source (NG), and 1-20ppm for
the exhaust (water vapor contained).
I know it's hard to find commercial NH3 analyzer. So, any clue from you is
much appreciated!
Thanks. |

发帖数: 2024 | 8 Just consider the dominant pole response of the front end. It will be -20dB/
dec after it passes the 3dB bandwidth. It's the determined by response of
the MOSFET/HEMT electronics. Typical bandwidth of the spectrum analyzer is 0
-2GHz, some 10GHz. In military, you do have 100GHz spectrum analyzer. But
you need to consider the absorption curves of the atmosphere. Range of THz
signal is limited by this absorption. The transparent window of the air is
around 2GHz and 40GHz if I remember correctly.

最高可以测试的微波频率是多少啊？
为什么会受到这个限制呢？是由于这些频谱仪的内在设计原理所限制而不能测试超过

那如果要实验上检测这个100GHz以上甚至THz的电信号该怎么办呢？

Also, average whatever you got is not a good solution, since how are you

is the SAS mixed model book published in 2006. Another starter book is
Miliken and Johnson's book on messy data.
In biometrics, data with repeated measurement is called longitudinal data.
You may also find reference book on the analysis of longitudinal data.
For your problem, the covariate is time-dependent. It might be hard to find
a direct solution out of a text book. Search on CIS for some articles in
this area.
