Manufacturers of the early 1900s were using steel pipe, angle or channel for the greenhouse superstructures . 二十世纪初期制造商们就已用钢管、角铁以及槽钢之类的材料建造温室的上部结构。
If a greenhouse is extra tight, the airflow from the inlet side of the house to the exhaust fan will be relatively well confined . 如果温室很密闭，室内从进风面到排风扇的气流就比较好控制。
Many scientists believe that a number of these greenhouse problems will come to pass unless actions are taken to slow some of today's trends . 多数科学家相信：某些温室效应问题会发生，除非我们采取行动减缓目前的发展趋势。
While most scientists agree that the greenhouse effect is coming, there aren't enough data yet to say with absolute conviction what its consequences will be . 大多数科学家都承认温室效应正在来临，但还没有充分的数据能使人们完全信服地说出其结果会是怎样。
