一 填空 单片机与普通计算机的不同之处在于其将（ ）（ ）和（ ）三部分集成于一块芯片上。 答：CPU、存储器、I/O 口 8051 与 8751 的区别是：答：内部程序存储器的类型不同 在 MCS－51 单片机中，如果采用 6MHz 晶振，1 个机器周期为（ ）。答：2us。 内部 RAM 中，位地址为 30H 的位，该位所在字节的字节地址为（ ）。答：26H 若 A 中的内容为 63H，那么，P 标志位的值为（ ）

This formula applies to any type of firms in the output market 1. Competitive Output Market Competitive industry: Many firms: Firms are independent of each other in decision making Identical product: Each firm faces a horizontal demand curve at the market price Free entry: Zero profit in the long run A competitive firm takes the market price as given. For a given market price p

1.1 The element carbon has atomic number 6, and so it has a total of six electrons. Two of these elec- tr rons are in the Is level. The four electrons in the 2s and 2p levels (the valence shell) are the valence electrons. Carbon has four valence electrons 1.2 Electron configurations of elements are derived by applying the following principles:
