Not sure what kind of 天线 you plan to make, so I will assume it is for over
the air TV.
Since you did not specify what kind of coax, I will assume you need RG6 (18
AWG center conductor and 75 ohm characteristic impedance) with F connector,
you can find them in most walmart, target, and all best buy and radio shack.
Some will have RG59 cheaper, depending on how far you will have to run,
they might also work for you.
But if you are building a Amateur radio 天线, you will need different kind
of Coax,

As the long Russian winter drags on, fish in the ponds of St. Petersburg
become increasingly desperate for oxygen, clustering in vast thrashing
masses at shrinking holes in the ice. Not only does ice block oxygen that
could be diffused into the water from the air, but it also impedes sunlight
from reaching oxygen-generating plants and algae in the water

a. A player shall not hold, push, charge into, impede the progress of an
opponent by
extending a hand, arm, leg or knee or by bending the body into a position
that is not normal.
Contact that results in the re-routing of an opponent is a foul which must
be called immediately.

来自主题: Basketball版 - Ray Allen胳膊没躲开那个球
规则里面并没有你说的先跑或者先跳的前提,也没规定你一定要主动伸手
事实上,对contact initiated by defender是有专门的规则判定的
简单的,如果你一直把胳膊放在我身边并且伸出来到你体前,我这时候想向你侧面跑被
你胳膊阻拦并因此跑动
动作受影响,算不算犯规?
progress本身只是指技术动作,并没有说一定是脚下如何动
这个动作判定投篮犯规很简单,首先impede了对方动作的progress所以算防守犯规
其次对方动作符合act of shooting的定义,所以判定为shooting foul.
跳与不跳,并无影响

the path from the signal source to the ear is subject to a lot of things --
different components, circuit boards, transmission impedance, attenuation,
etc. so the signal level perceived by human ears are not always the same
between the left and right channels (or among the 6 or 8 channels in a
surround system).
that's why most receivers are supplied with a "balance" knob to compensate
for the differences between the left and right channels.

来自主题: Fitness版 - 新手测了一下体重和体脂
现在通用的电子秤测量体脂的方法都是使用生物阻抗分析法
(Bioelectrical impedance analysis)来间接地推算体脂。
具体当然比较复杂,说白话一些意思就是秤就是一个测量电阻
的表,测出身体的电阻。然后水和脂肪的电阻都是已知的,
通过测量出的身体的电阻就可以推算出人体的脂肪含量。
这个的基础是根据已知的不同年龄、不同性别的男女身体中
水分和脂肪含量的不同来估算的,所以使用之前需要输入测量者
的年龄性别等信息。
这个测量当然只能是一个估算,因为首先每个具体的人身体水分含量
和标准值就有差别,运动前后或者身体代谢的某些原因的影响下,
身体水分含量也会起变化。另外测量电阻本身也受体温等因素影响。
各种因素综合起来,结果当然就会有比较大的出入。
不过这个出入跟脚底板肥肉的多少还是不一样的,呵呵。

In measuring body composition, it's not only important what the result is,
but also how you arrived at it. For example, let's say you're a woman with a
skinfold or bioelectric impedance body fat measurement of 22%. At first
glance it seems that you fall into a healthy body fat range. The problem is,
since the error factor for both of these methods is up to +/-8%, this
number could mean your actual body fat might be as low as 14% (risky – low
body fat) or as high as 30% (borderline excess fat). I
