2) Aflow camera moves copy smoothly through the camera to expose film which moves with the reduced image.移动(轮转式) 摄像机可以将拷贝物平滑地移过镜头以便使胶卷曝光,该镜头则随着图 像的缩小而不断进行调整。 注释: a flow camera是两种常用缩微摄像机的另一种,也叫 Camera - Rotary-Flow轮转式摄像机。 through the camera中的 camera译 为“镜头”;不定式 to expose film是目的状语;注意定语从句中的关 系代词 which指代的是 the camera,而非fem;介词短语 with the reduced image可视为方式状语。 3)Alternatively, it may be produced by computers, i.e. COM ( com puter output microfilm).或者,它也可以由计算机生成,例如, 计算机输出缩微影像。 注释:cOM( computer output microfilm)是指将计算机输出的二进 制编码数据转换成人可读取的缩微影像,记录在感光胶片上的技术,简 称coM。coM已成为一种与计算机输出缩微品化有关的技术总称。常 用的coM缩微品是16毫米卷片和缩微平片。它们的缩微倍率大多采用 24倍或42倍。 2021/2/20 P3

Task 2. Read. Write and Translate Read and Reply Directions: Students are required to read aloud the whole text after the teacher. Then give short answers to the following questions a)What s the different method of filming used to create microform media? To create microform media, there are three different methods to be used: a planetary camera uses a method of filming in which the document and the film remain stationary during exposure. A flow camera uses a method of filming in which the paper and film move simultaneously. while COM may be produced by computers b)What type of film is often used to microfilm? Normally microfilming uses high resolution panchromatic high resolution monochrome stock. Positive color film giving good reproduction and high resolution can also be used c)What s the characteristic of, microfiche camera? A microfiche camera is a camera used for producing microfiche, All microfiche cameras are planetary with a step and repeat mechanism to advance the film after each exposure. Cameras. for high output are loaded with a roll of 105 mm film 2021/2/20 P 8

Read and Judge (T)1. No one camera produces all types of microforms, you must match the camera with the film you need (T)2. Because the document is stationary during filming, the planetary camera can produce a film image that is superior to the image from a flow camera (F)3. The planetary camera can produce either 16mm or 35mm film; some models can convert from one to the other. They are the same with the flow camera (T)4. The step-and-repeat camera is a variation of a planetary camera. It produces 105mm microfiche and positions images on the fiche in a grid pattern (T)5. A planetary camera can only film one side of a page at a time. While some models of a flow camera can film both sides of a document simultaneously (F)6. COM, a high-level medium, produces high quality microfilm, micrographic or microform often in microfiche format. While the other microfilming can not connect to a computer to index film G20212120P9WG End 1
