No matter looking at it from whatever angle, cost (material cost,
construction cost, delivery cost, etc.) will always be a major factor.
Unless there will be some revolution in pipe material research, using
different materials at different sizes will be the most cost efficient way,
at least in the foreseeable future.
Secondly, application plays another significant role during pipe selection.

leakage from a frozen pipe back in Jan. The water left some marks on the

The pipe broke because of the cold weather. Although the lease says we need to

Black-bellied Plover可以说是比较容易识别的滩鸟之一，首先因为它的黑肚皮是很显
眼的，其次它的体形在北美的plover里是最大的，比Piping Plover,Snowy Plover,
Semipalmated Plover等要大很多，而且体型不大一样（其它的这些脖子都很短，整只
鸟显得很圆乎乎的样子）。
但是跟它类似的还有American Golden-plover，二者成年鸟的羽色很不一样，应该不容
易混淆。但非成年鸟的话还是有弄混的可能。
下一只，是我上月在Texas看到的，当时以为是American Golden-plover（当时海滩上
鸟很多，而我忙于拍摄濒危的Piping Plover没有看仔细），但现在认为也是Black-

最近有一则穆斯林自相残杀的新闻，总括而言就是说：
自1948年以来，近1000万穆斯林丧生其他穆斯林手下。
为甚么没有人对此提出抗议？因为双重标准。引用以色列驻联合国大使吉勒曼（
Dan Gillerman）在2008年说的话：「当基督徒杀穆斯林，被称为十字军东征；当犹太
人杀穆斯林，被称为谋杀；当穆斯林杀穆斯林，就好像谈天气那么平常，根本没有人在
乎。」
已故政论家杭廷顿（Samuel P. Huntington）曾观察道：「且看伊斯兰的週边关係
，会发现穆斯林很难与邻舍和平共存，这自然引发一个提问：20世纪下半叶穆斯林与非
穆斯林之间的衝突模式，是否也是当时代其他文化族群间的衝突模式，事实并非如此。
穆斯林占世界1／5人口，然而在1990年代，他们牵涉种群暴力，比世上任何其他文化都
多…伊斯兰的边境血迹斑斑，其内在亦然。」

我们需要在m-1，m,m-1进行选择
if sum(m-2) < sum(m+1,n) then t = m-1;
else if sum(m-1) < sum(m+2,n) 的值 t = m;
