queen's university, Canada. Most solar panels are made with crystalline silicon, but you can also make solar cells out of amor- phous(非晶形的)silicon, commonly known
(6)thin-film silicon. They don't create as much electricity, but they are lighter, flexible, and cheaper. And, because they (7) much less sil- icon, they have a greener footprint. (8), thin-film silicon solar cells are vulnerable to some bad-news physics in the form of the Staebler-Wronski effect. "That means that their efficiency drops when you (9) them to light--"pretty much the worst possible effect for a solar cell," pearce explains, which is one of the (10) thin-film so- lar panels make up only a small fraction of the market. However, Pearce and his team found a (11) to engineer around the Staebler-Wronski effect by incorporating thin-film silicon in a new (12) of PVT. You don't have to cool down thin-film silicon to make it work. In fact, pearce's group discovered that by heating it to solar-thermal operating temperatures, near the boiling (13) of water, they could make thicker cells that largely (14) the Staebler-Wronski effect. When they applied the thin-film silicon directly to a solar thermal energy collector, they also found that by baking the cell once a day, they (15) the solar cell's electrical efficiency by over 10 percent.

2013年职称英语等级考试(理工类A级)真题参考答案
第1题:
【正确答案】:A
【参考解析】: 题意:规则太严格,不允许人为误差。 划线词为形容词,意为“严格的,刚性的”。 A项inflexible“不可改变的”,例:Workerslnsisted that the new system was too inflexible.工人们坚持认为新制度过于僵化。 B项意为“一般的,总体的”,例:The figures represent a general decline in employment.这些数字表明了就业率的总体下降。 C项意为“复杂的”,例:This project involves a lot of complex technical problems.这个方案牵涉到许多复杂的技术问题。 D项意为“直接的”,例:All genuine knowledge originates in direct experience. 一切真知都源于直接的经验。故选A项。
