发帖数: 5114 | 1 ACI 21章里说，只有不属于vertical lateral resisting system的slab才属于
diaphragm
所以我就糊涂了，two way slab本身已经有column strip是要按照moment frame来设计的
那么这个slab本身是不是同时要满足moment frame和diaphragm两个小节里面的要求呢？ |

你的 slab 都满足 moment frame 了, 也满足punch shear 和moment shear transfer
了， diaphragm 验算也会是 trivial 的,肯定大大超过demand.

我看一般都是strong axis I column 用在BRACE方向，这样BENDING比较好，有没有
code规定必须strong axis,还是只要计算上可以，weak axis column也可以用在brace
frame上？ |

标 题: video frame grabber 一问 兼 合作请求
发信站: BBS 未名空间站 (Wed May 31 13:18:23 2006)
诸位 EE 的大侠们，偶是物理系的。
最近遇到个问题，就是我的 infrared 相机的 digital frame grabber (16-bit) 不工作
了，所是 "the board can not be initialized"。也不知是硬件还是软件问题。糟糕的
是，这 grabber 是 Dipix XPG-1000, 早就不生产了，维护都难找 (Dipix sold the XPG
tech to Dalsa Coreco)。
所以，我琢磨着买块 video grabber (8-bit)，虽然数据质量低了，但总归相机还能派上
用场。不知大家知不知道有什么 video grabber 能够储存 FITS 文件格式的？ JPEG 什
么的作 scientific 的东东是不行了。不知 TIFF 可不可以，好像有些 research |

table
data frame
matrix
?
Can I just perform matrix computation (such as product, addition,
subtraction) between two data frames?
Thanks |

发帖数: 2174 | 7 1. There is no "table" in R.
2. Data frame and matrix are totally different things. A data frame is
basically a list, with some extra attributes. A matrix is a vector with some
extra attributes.
3. You can convert them in certain cases, but not all. |

发帖数: 32207 | 9 我觉得如果尺寸级别相当的话,body on frame的车通常会比unibody的更重
以至于你后面的比较就比较没意义了:D
比如GL450跟一群美式fullsize SUV的对比
另外我没法理解你说的unibody刚性更好的说法,如果设计跟材料的水平相当的话
body on frame的缺点就是(相对unibody)重心高,空间小(或者说利用率差),自重大
这是针对非越野情况来说
好处么,似乎一两句未必说得完,得详细比较一下.

isn't the copper wires better? |

发帖数: 7856 | 11 body-on-frame还是unibody和悬挂是否独立没有关系。
body-on-frame也可以是独立悬挂，比如Sequoia，Armada，Expedition，悍马H1等等；
Unibody也可以是非独立悬挂，比如马屎蛋。 |
