1,声卡的插孔上有MIC IN和INE IN ,各表示什么意思?
MIC IN 是耳麦插口,或者音箱喇叭插口,音频输出用的。INE IN 耳麦一般有两个插头,一个管听声音,另一个管语音,这个就是音频输入用的。Mic通常是单声道的。Ine in则是立体声的。mic是带电的,所以可以供电给麦克风,如果把麦克风插在Ine in是行不通的。扩展资料声卡的组成:声卡是将话筒或线性输入的声音信号经过模/数转换编程数字音频信号进行数据处理,然后再经过数/模转换变成模拟信号,送往混音器中放大,最后输出驱动扬声器发声。下面对声卡的各个组成部分做一个介绍。1、数字信号处理芯片数字信号处理芯片可以完成各种信号的记录和播放任务,还可以完成许多处理工作,如音频压缩与解压缩运算、改变采样频率、解释MIDI指令或符号以及控制和协调直接存储器访问(DMA)工作。2、A/D和D/A转换器声音原本以模拟波形的形式出现,必须转换成数字形式才能在计算机中使用。为实现这种转换,声音卡含有把模拟信号转成数字信号的A/D转换器,使数据可存入磁盘中。为了把声音输出信号送给喇叭或其他设备播出,声卡必须使用D/A转换器,把计算机中以数字形式表示的声音转变成模拟信号播出。3、总线接口芯片总线接口芯片在声卡与系统总线之间传输命令与数据。4、音乐合成器音乐合成器负责将数字音频波形数据或MIDI消息合成为声音。5、混音器混音器可以将不同途径,如话筒或线路输入、CD输入的声音信号进行混合。此外,混音器还为用户提供软件控制音量的功能。

3,in-line citation 是什么意思
in-line citation:文中引用,就是指在论文中引用参考文献,在文中做标注,在文后按标注注明引用的出处。
例如:主编靠编辑思想指挥全局已是编辑界的共识 [1] ,然而对编辑思想至今没有一个明确的界定, 故不妨提出一个构架…...
(其中共识后面的[1]就是文中引用标注,)
所以You must have an in-line citation for this summary.可以翻译成:你必须在这个总结里应用一个文中引用。
