It took me an hour just to dismantle the old faucet. My kitchen sink has
garbage disposal and numerous water pipes which makes it almost impossible
to
use a regular wrench, not enough space to use a basin wrench.
The old Moven faucet is install in away that you can only remove the nut
from
below the sink using a customized socket tool from Moven.
Unfortunately, the stupid socket tool for my new Moven sink does not fit the
old nut. I have to go to Homedepot twice t... 阅读全帖 |

reaching boiling point goes.
When water starts to heat up a little bit, the increased movenment causes
the water molecules to absorb positive heat wave faster. So from cold to
warm might take a longer time than from warm to boiling point. |

第二张图中讲的是春天鱼类季节运动（SEASONAL MOVENMENT),第一栏说的是早春，刚刚
溶冰，此时水面水温低于4度（4度时水层中间跃温层），虽然在升温通道中。此时水温
低于下面任何水层，自然吸收氧气比底部多。
第二栏是春季转换，转换点就是水面温度上升达到4度的时候，此时全同温，（全同温
的时间也许很短，对于浅水湖，也许一个大风天就全部同温了）。各个水层都有鱼。
春季后期，水面温度继续升高，但是氧气却是底部低温水更多，但是，底部水温又太冷
了，趋利避害，鱼大多数选择水表层。
文章观点及这副图都没有错。只是第一栏没特别注明是低于四度的水温。
一个疑问啊 -- 图一中说水温升高，水从空气中吸氧。这个跟文中的观点是否相抵触？ |

Should be 大气压 X 地球表面积 = 大气重量
This estimation is really a very nice approximation due to
the tiny vertical movement of air in large scale compared with the
horizontal movement (vertical movenment around cm/s, and horizotan 10m/s
for typical synoptic scale). The physics principle
of this estimation is simple, hydrostatic approximation,
gravity is balanced by buoyance since no vertical acceleration.
That is
dP/dZ = - density * g
Usually this can be a very good appro |
