19、rgest ones down to the hand-held calculator, as well as a wide variety of other electronic systems. 分析：该句的主干为红色部分。 ranging from the very largest ones down to the hand-held calculator是由现在分词 ranging弓I导的分词短语，修饰computer of all types。翻译：逻辑电路应用在开发各种类型的计算机中，范围大至巨型计算机，小至便捷式计数 器，同时它还应用在各种各样的电子系统中。Computation

20、al arithmetic is based on the decimal or Arabic number system, which uses ten states for each variable, designated by the digits 0 through 9.分析：其中由which引导的非限定性定语从句中的动词 use的用法是use sth for sth for each variable 是状语，而 designated by the digits 0 through 9是过去分词短语，做 ten states 的后 置定语， 但因其较长， 放在句末， 并用逗号将其与被修饰词分隔， 这就是语法中常说的 “做 定语的分词短语与其被修饰词分隔”的现象。翻译：算术运算基于十进制或者阿拉伯计数制，这种进制使用由数字0到 9 指定的十个状态表示每个变量。For example, two inputs of a NOR gate are tied together to a common input A, so that the output is the
