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。

The main tool is the notion of the Lipschitz condition with positive non-decreasing integrable function L-average along the piecewise geodesic which includes theclassical Lipschitz condition as well as theγ-condition as special cases.

同时，我们在研究中引入了沿着分段测地线的关于取正值非减可积函数L-平均的Lipschitz条件的概念，从而把流形上的Kantorovich定理及Smale理论统一起来研究。

This is a public beach, so everyone can come here. Each walked on the beach with bare feet. If there are iron cans or nails on the beach, people may get hurt. Thus, I saw volunteers detecting the beach back and forth with metal detectors and detectaphones and taking away any hurtful ironware. This is American "humanity"-"Love me, love my dog";"do to others what you want to be done to you," which is the spirit to make the US powerful.

由於是公共沙滩，任何人都可以来玩，每个人都是光脚走在沙滩上玩耍，要是有铁罐、钉子，则会伤害到人，因此，我看到有义工用类似军队用的地雷侦测器，头戴侦听耳机在沙滩上来回扫瞄，将会伤人的铁器带走，这是美国的「人道精神」、「爱己及人，爱物及物」，这是美国所以强大的精神支柱。

Similar to the border trap capacitance at low-frequency C-V curves, additional recombined charge per cycle at low-frequency charge pumping measurements could be attributed to the repetitive recombination of majority and minority carriers which instantly tunnel into and out of the border traps located near the high-k/oxide interface.

如同在低频电容—电压图形中的边界缺陷电容值一般，在低频电荷泵浦方法中所量测到的额外每单位循环再结合电荷载子数目，皆可归因於反覆的多数与少数载子再结合，而此一现象主要发生於高介电常数介电层/二氧化矽氧化层介面附近的边界缺陷。

The samples are received cutting test, and compare their chips withthose of HPb59?, we find that the cutability of nonleaded freeutting is70?096 of that of HPb59?.

将研制的试样进行切削加工，并将其切屑与HPb59-1的切屑进行比较，测得该易切削黄铜的切削性能可达到HPb59-1的70-80％。

"It is far more sensitive than radiography for bone erosion in patients with early rheumatoid arthritis, and can detect pre-erosive features, such as osteitis and synovitis, along with tendonitis and potentially other MRI features that can be used to predict which patients will go on to severe destructive joint damage and irreversible functional disability," Dr.

Peterfy医师进一步指出，对於早期类风湿性关节炎病患而言，MRI在骨质糜烂的诊断上，远比X光摄影灵敏许多，且可侦测到糜烂前的特徵；像是骨炎与滑膜炎、连同肌腱炎与可用於预测严重破坏性关节损害及无法恢复的功能障碍，能一开始就向病患展现准确的预测，进行一个有效率的病患管理是非常重要的。

The relationship between parameters of airborne laser bathymetry and its maximum penetration depth is discussed.

以确定的参量建立的系统具有白天 4 9m和晚上 6 5m的最大测深能力，可完全满足在沿岸带以及岛礁的测量要

Therefore, how to measure the strain field of bending for flexible polymer substrate that constitute the flexible display is an important technique. In view of the fact that traditional devices such as strain gages and photoelasticity are not suitable for measure large deformation, this study develops noncontact measurement as the first choice.
