Blind photography sounds strange．But a striking exhibition of photographs in California argues that it develops as a result of the contemporary art．The show "Sight Unseen", at the California Museum of Photography until Aug．29, includes everything: underwater scenes, landscapes, abstracts and everything else you might expect from a "sighted" photographer．

How do the blind take their photographs? Some rely on assistants to set up and then describe the shots （镜头） , and others just point and shoot in the right place．"Just like any good artists," says McCulloh．"They have their unique ways of operating．" One participating photographer is Pete Eckert, an artist with multiple degrees in design and sculpture who only turned to photography after losing his vision in the mid-1990s．He opens the shutter （快门） on his camera and then uses flashlights, lights, and candies to paint his scene on film．A former fashion photographer in Chicago, Weston, lost his vision due to AIDS in 1996 and focuses on images of destruction and disability．His photos are also a star of the show．

What do gallery-goers say? "I was very impressed by it．The technique and experience was amazingly different," says John Hesketh, a printmaker in Anaheim．"You never have a sense of feeling sorry for these people because they've worked very hard to prove their value．"

Beyond the praise, however, the exhibition also makes a great example for disabled people everywhere．That point was explained in early May during a discussion on the TV show．At the very end of the talk, one attendee expressed his opinion．"This exhibition is extraordinary and revolutionary for many reasons．I think that by being an artist with a disability, you are continuing the work of those people who fought for basic civil rights to gain access and to have a voice．In that way, it's so wonderful that your photographs say it all．"

伸长率是应力－应变曲线中试件被拉断时的最大应变值，它是衡量钢筋塑性的一个指标，与抗拉强度一样，也是钢筋机械性能中必不可少的保证项目。关于伸长率的描述正确的有（）。

A.伸长率又称延伸率

B.伸长率值越小，表明钢材的塑性越好

C.伸长率与标距有关，对热轧钢筋的标距取试件直径的10倍长度作为测量的标准，其伸长率以10表示

D.伸长率的计算，是钢筋在拉力作用下断裂时，被拉长的那部分长度占原长的百分比
