Locking a file is a lot like borrowing a book from the library; if Harry has locked a file, then Sally cannot make any changes to it. If she tries to lock the file, the repository will deny the request. All she can do is read the file, and wait for Harry to finish his changes and release his lock.

考虑这个情景，我们有两个共同工作者，Harry 和 Sally，他们想同时编辑版本库里的同一个文件，如果首先 Harry 保存它的修改，过了一会，Sally 可能凑巧用自己的版本覆盖了这些文件，Harry 的更改不会永远消失(因为系统记录了每次修改)，Harry 所有的修改不会出现在 Sally 的文件中，所以 Harry 的工作还是丢失了

When used for a time, the lock may not be opened smoothly. Do not dip mechanical oil into the lock. Instead, slip some French chalk or pencil fines into it.

In this dissertation, digital lock-in detection techniques under integer period sampling and non-integer period sampling are separately investigated (1) Under integer period sampling, digital signal sequence is acquired through sampling the measured signal, but digital reference sequence is acquired through mathematical operation, then digital lock-in detection can be realized by calculating crosscorrelation function of digital signal sequence and digital reference sequence Harmonic measure is also analyzed, and a method of measuring harmonic of a periodic signal under aliasing is put forward.

本文对使用采样ADC把模拟信号转换为数字信号并通过计算数字信号的相关函数来实现锁定检测的技术进行了研究，在此基础上设计了一个多功能的数字LIA并在一些科学实验中进行了应用。本文对整周期采样和非整周期采样时的数字锁定检测技术分别进行了研究。(1)在整周期采样时，对被测信号进行采样得到信号序列，而参考序列由数学运算得到，通过计算信号序列和参考序列的互相关函数就可实现锁定检测。
