对于多层厂房，在其结构形式一定的条件下，若厂房宽度和长度越大，则经济层数和单方造价的变化趋势是( )。

A．经济层数降低，单方造价随之相应增高

B．经济层数增高，单方造价随之相应降低

C．经济层数降低，单方造价随之相应降低

D．经济层数增高，单方造价随之相应增高

答案

参考答案：B

解析： 确定多层厂房的经济层数主要有两个因素：一是厂房展开面积的大小，展开面积越大，经济层数越高；二是厂房宽度和长度，宽度和长度越大，则经济层数越高造价也随之相应降低。

     J.K Rowling was born in England in 1965. She loved reading, and wrote her first story "Rabbit" when she

as an English teacher in the afternoon and evening. She got married to a Portuguese TV journalist and had a

daughter called Jessica.

Even plant can run a fever, especially when they’re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3,000 feet away straight up. A decade ago, adopting the infrared （红外线）scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide (杀虫剂)spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest(害虫)problems.

Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat sent out by crops. The data were transformed into a color-coded map showing where plants were running “fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide that they otherwise would.

The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements（改进）ininfrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States,” says George Oerther of Texas A& M, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.
