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。

Nondiscretionary accruals are on average priced by equity market while not discretionary accruals. We do not find evidence that Chinese investors are functionally fixated on earnings, and instead value-relevance of accounting numbers is mainly reflected on operating cash flows.

非操控性应计被股票市场定价了，而操控性应计并没有被股票市场定价；没有发现股票市场上存在净利润的&功能锁定&现象；会计数字的价值相关性主要体现在经营活动现金流量上。

We proposed that the non-adiabatic passage at zero-crossings of quadrupole splitting would not lead to the great loss of the spin locking signals, and the second-order quadrupolar interaction had significant effects on triple-quantum coherences, which was responsible for the fast decay of the signals; the both experiments and numerical simulations supported this point of view.

另外，在该谱仪上还进行了四极核钠-23的自旋锁定效率的研究；从含时Shr〓dinger方程出发，提出了一个更为确切的四极分裂过零处的绝热通过判据，并指出四极分裂过零处的非绝热通过不会导致锁定信号的快速消失，四极相互作用的二阶项对三量子相干的影响不能忽略，它是引起锁定信号快速消失的原因；实验和数字模拟的结果证实了这个理论。
