发帖数: 4125 | 1 You are talking about a split phase electricity distribution system is a 3-
wire single-phase distribution system. It is the AC equivalent of the
original Edison 3-wire direct current system. Its primary advantage is that
it saves conductor material over a single ended single phase system while
only requiring single phase on the supply side of the distribution
transformer.

leg delta) According to Article 110.15 of the 2 |

发帖数: 4125 | 3 An accepted guideline is that the wire impedance should not exceed 5% of the
entire circuit. For a given material, resistance is a product of length and
thickness. For this reason, lower impedance speakers require lower
resistance speaker wire.Longer cable runs need to be even thicker. Once the
5% guideline is met, thicker wire will not provide any improvement.
Maximum wire lengths for two conductor copper speaker wire
Wire size 2 Ω load 4 Ω load 6 Ω load 8 Ω load |

"Should I be concerned about a home containing Aluminium Wiring?"
ANSWER
Most electrical wire is made of copper. Copper is predominately used in
residential construction with the exception of the service cable and single
purpose high-amperage circuits such as sub-panels, electrical ranges or air
conditioners. Since copper is a better conductor than aluminum, the aluminum
wire must be larger to safely carry the same current as copper.

这个房子，学区不错，院子很大，价格很公道，post当天看房，当天下午出了full
price offer抢到的。
做房检的时候总的说来比较愉快，结果今天读房检报告。看到一句话：地下室后墙有一
点cracked，房检认为可能是那面墙外面的downspout和sump pump discharges into
underground conductor at the exterior side of the wall。 可能有leaking，导致
有水漏进土壤，冬天结冰（我们这小半年都是冬天，基本大雪）后挤压墙面造成的。
问LG，他说他跟着房检看的，觉得不是大问题。 我很焦虑，不知道对foundation有影
响没有？

Violin II， Viola，Bass， Cello。很好听。然后7 年级的学生离开，一个8年级的
女生 Violin 独奏，有钢琴伴奏，演完之后掌声雷动，很多听众站了起来在鼓掌，然后
又有很多人也陆续跟着站起来鼓掌，有人给这女生献花。接下来就是Wind Ensemble 走

发帖数: 1437 | 15 我来说说小提琴。
铃木教程是针对小孩子的，但一般最小四岁开始，从每周半小时开始，因为小提琴学起
来是很枯燥的，小孩的注意力不能集中太久，林木教学法同时也鼓励家长自己也有把琴
一起学。也鼓励每周一次group lesson, 做音乐游戏，theory, 啥的。
楼主说的年薪很高的top conductor啥的少之又少，我看绝大部分音乐毕业生（我知道
的包括朱丽叶本科另一很好私立大学音乐硕士，，另一个音乐世家出身自己很不错的音
乐学院硕士等等）也就是要不在学校当音乐老师，要不在乐团混着（年薪很少的），然
后就是私人授课。小提琴非常难出头，因为学的人特别多，竞争激烈，首席小提琴手也
就一个。
我知道那个音乐世家那个，（有一个很不错音乐学院是以她祖父命名的），她自己是六
七岁开始学小提琴的。我知道的那个朱丽叶本科那个，她就是在公立学校八九岁时才开
始学乐器的，高中时才拜师苦练。。人有天分老天爷赏饭吃，呵呵。 |
