Rainmaking
1 The idea of rainmaking is almost as old as man,but it was not until 1946 that man succeeded in
making rain.In ancient times,rainmakers had claimed to bring rain by many methods:dancing,singing,
killing animals(including humans).
2 For a long time,men have understood where rain comes from.Water from the surface of oceans and
lakes becomes part of the air,where it forms clouds from which rain falls.But exactly what starts the forma-
tion of raindrops was not known until quite recently.A man named John Aitken proved that drops of water
gather around tiny bits of dust or other matter. The centers of the drops are so small that the human eye can-
not see them.Without such centers,it seems raindrops do not form.
3 During World War Ⅱ,Dr. Irving Langmir,and his assistant Schaefer,were hired by the General
Electric Company to study how and why ice forms on the wings of airplanes.They went to a mountain in New
Hampshire,where snowstorms are common and cold winds blow. They were surprised to find that often the
temperature of the clouds surrounding them was far below the freezing point,and yet ice did not form in the
clouds.
4 After the War,Schaefer experimented with a machine that created cold,moist air similar to the air
found in clouds.To imitate the moist air of a cloud.Schaefer would breathe into the machine.Then he
would drop into the freezer a bit of powder,sugar,or some other substance.For weeks and months he tried
everything he could imagine.Nothing happened.No crystals of ice were formed.None of the substances
would serve as the center of a snow crystal or raindrops.
5 One July morning,Schaefer was dropping in bits of various substances and watching the unsuccessful
results.Finally,a friend suggested that they go to eat lunch and Schaefer went with him.As usual,he left
the cover of the freezer up,since cold air sinks and would not escape from the box.
6 Returning from lunch,Schaefer found that the temperature of the freezer had risen to a point higher
than that required for ice crystals to remain solid.There were two choices now.He could close the cover and
wait for the freezer itself to lower the air temperature,or he could make the process occur faster by adding dry
ice a gas in solid form that is very,very cold.He chose the latter plan.As he dropped the steaming white
dry ice into the freezer,he happened to breathe out a large amount of air. And there,before his eyes,it
happened ! He had made ice crystals,not by adding centers to the moisture,but by cooling the breath so
much that the liquid had to form crystals!Then he began to blow his breath into the freezer and drop large
pieces of dry ice through it to create crystals which became a tiny snowstorm falling slowly to the floor of his
laboratory.
7 After planning carefully,Schaefer made an experiment by dropping dry ice from his plane to the
clouds below him.As was expected,snow formed and fell from the bottom of the cloud.Schaefer succeeded.
He made history.

[简答题]
A施工单位承包了某建设单位扩建工程的一个新建轻烃储存罐区,罐区主体工程为4台2000m3球形储罐。建设单位将球罐区及其附近一块区域划给A施工单位作为施工和办公用地,A施工单位进行了施工总平面图设计。施工开始后,发生了以下事件:
事件1,施工进行到第一台球罐开始焊接球罐壳体。进行焊缝清根,电弧气刨火花引燃地面上一处易燃物,火势很快发展,使球罐外的帆布焊接防风棚起火。施工人员一面报警,一面自行救火,但打开临时消防栓,没有水,采用施工用水,水量不足,不能控制火势。消防车赶到时,由于道路被堆放的脚手架和工程用钢管阻塞,无法靠近着火点,只得组织人工清障.在清障完成,消防车到达球罐着火处时,防风棚已基本烧光。
事件2,工程进程将半,建设单位组织供电系统改造。由于施工单位一问现场办公室和一间库房处于原主动力埋地电缆经过位置,必须拆除搬迁。搬迁过程中,库房内材料配件标识被混,以至于尔后出现材料错用现象。事后检查,未查到建设单位提供的该地块的地下设施分布图。
事件2中施工单位现场办公室和库房拆除搬迁造成损失的原因是什么?
