3. When measuring current, the circuit must be opened and the meter inserted in series with the circuit or ponent to be measured. 當(dāng)測量電流時,必須斷開電路,(然后)將萬用表與待測電路或元器件相串聯(lián)。 4. Moore39。s law, which predicted that the number of devices integrated on a chip would be doubled every two years, was accurate for a number of years. 摩爾定律指出:集成在一個芯片上的器件數(shù)量將每兩年翻一番。這在許多年來都是正確的。 得 分五、綜合運用(每小題 20分,共 20 分) C is monly considered to be a structured language with some similarities to Pascal. In C, a block of code is a logically connected group of program statements that can be treated as a unit. You can create a block of code by placing lines of code between opening and closing curly braces. For example:if(x10) { printf (“too low, try again”)。 reset_counter(1)。}The two statements after if that are between the curly braces are executed if x is less than 10. These two statements with the braces represent a block of code. They are linked together: one of the statements cannot execute without the other also executing. (將上面的短文翻譯成中文) 與Pascal語言相似,C通常被看成是一種結(jié)構(gòu)化語言。在C語言中,一個代碼塊是一組邏輯上相聯(lián)系的程序語句,它們可以被看成是一個單元(塊)。你可以在左右兩個花括號之間插入幾行代碼創(chuàng)建一個代碼塊。如: if(x10) { printf (“too low, try again”)。 reset_counter(1)。 } 如果x小于10,if 后面的位于花括號之間的兩個語句就被執(zhí)行。這兩個句子連同兩個花括號表示一個代碼塊,這兩個語句是連系在一起的:不可能只執(zhí)行其中一個語句,而不執(zhí)行另一個語句。 當(dāng)前第9頁,共10頁 當(dāng)前第10頁,共10
