卤族元素氟、氯、溴、碘与银的化合物,统称为卤化银。其中氯化银、溴化银、碘化银都应用于感光材料,只有氟化银不能应用。传统X线胶片的感光物质是溴化银加上微量的碘化银,扁平颗粒胶片的感光物质仅为溴化银。卤化银是胶片产生影像的核心。卤化银是以微晶体状态存在,卤化银的感光作用是以每个晶体为单位进行的。在其他条件相同时,晶体颗粒的大小、分布会给影像效果带来影响:①晶体颗粒大,感光度高;②晶体颗粒分布均匀,对比度高,颗粒性好:③晶体颗粒大小不一,宽容度大;④晶体颗粒小,分辨率高。

下列叙述错误的是()

A.传统颗粒是混合乳剂

B.扁平颗粒是单一乳剂

C.传统颗粒是三维形状

D.扁平颗粒是切割成二维形状

E.扁平颗粒的感光材料是碘化银

The very first capsule hotel to be opened in Shanghai has attracted many budget travelers with its prices, even though it is not fully operational yet.

The hotel consists of 68 "capsules", each 1.1-meters high, 1.1-meters wide and 2.2-meters long. The basic rate is 28 Yuan ($4.22) per person, plus an additional 4 Yuan an hour. The hotel also offers a package of 68 Yuan for 10 hours and 88 Yuan for 24 hours.

All of the capsules are imported from Japan where capsule hotels originated,and each is equipped with independent sockets, clocks, lights, TV and wireless Internet service. The hotel also has a public lavatory(洗手间),shower room, smoking room and shared guest room.

"This is a huge bargain compared with other budget hotels in Shanghai," said Ta Zan, the owner of the hotel. Ta used to stay at capsule hotels in Tokyo during his undergraduate years and worked at a capsule hotel while he was doing his MBA in Japan in 2005, so he knows how they work and how to make guests feel comfortable.

He based the hotel on capsule hotels in Japan but he has made some special changes based on Chinese guests' habits. "In Japan capsule hotels are usually equipped with bathtubs, but in China people are more willing to take a shower, so we have the shower room," he said. He has also separated the capsules into three snoring (打鼾的) zones so that guests who often snore won't disturb others. Like most of capsule hotels in Japan, the one in Shanghai is for men only.

But the idea of staying in such a compact space is not appealing to everyone. "I feel the idea is like putting a person in a coffin (棺材), and the price is also not that appealing. A bed at a youth hostel in Shanghai costs about 60 Yuan per night," said Wang Lei, a student from Beijing.
