云样自来水

有时候水龙头里流出的水是云样的，看上去象奶白色的碳酸饮料，而且过一会就变得清凉透彻了。这是因为水中溶解的空气释出为大量小气泡造成的。从Massachusetts Water Resources Authority抄了个不错的解释如下：

Why does my tap water look cloudy this winter?

By Massachusetts Water Resources Authority

Question: The hot and cold water from our kitchen sink sometimes comes out very cloudy. If we leave the water in the container, it then clears up quickly and the cloudiness disappears. Should we be using this water, even after it turns clear?

Answer: Cloudy water, also known as white water, is caused by air bubbles in the water. It is completely harmless.

It usually happens when it is very cold outside because the solubility of air in water increases as water pressure increases and/or water temperature decreases.

Cold water holds more air than warm water.

In the winter, water travels from the reservoir which is very cold and warms up during its travel to your tap. The air that is present is no longer soluble, and comes out of solution.

In addition, once water from our reservoir enters the transmission and distribution pipes, the water is pressurized. Water under pressure holds more air than water that is not pressurized.

Once the water comes out of your tap, the water is no longer under pressure and the air comes out of solution as bubbles (similar to a carbonated soft drink). The best thing to do is let it sit in an open container until the bubbles naturally disappear.

现代管理机构好比无机物，反应起来的各种指标容易被量化，无多少差池，但有多少质量，产生多少能，脱不了MC2。更高效的生产力会来自于更有机的组织机构，好比有机物，有再生特点，生生不息，抗干扰能力强，但不容易组建。而表现出智能特点的组织机构形式将是更难得的社会生产关系了。

boulevard, avenue, street, road

A boulevard is a broad city street that is lined with trees and landscaped. Many boulevards have an island of trees, grass, or flowers down the center, which divides the traffic.

A street is a public way in a city or a town. A street, usually, is accompanied by a sidewalk.

A road is a narrow, usually paved strip of land, used for transportation. Roads are, generally, found outside of urban areas.

An avenue is a broad passageway bordered by trees.
