The Nyquist law is applied to all the conventional compression coding algorithms, which prescribes that the sampling rate must be at least as twice as the signal frequency.
在传统的压缩编码技术中，采样均遵循奈奎斯特定律，该定律规定采样速率要高于原信号频率的两倍。
According to the feature of contacting measurement, the dissertation first puts forward the twice-sampling planning method for free-form surface in order to improve measuring efficiency.
根据接触测量的特点，为提高测量效率，本文提出了一种两次采样的曲面数字化规划方法。
According to the Nyquist Theorem, the sampling rate must be more than twice the maximum frequency component of the signal being measured.
根据Nyquist定理，采样率必须是被测信号最高频率分量的两倍以上。
Most traditional customer surveys are sent out periodically to a sampling of an organization's customers, typically once or twice a year.
大多数传统顾客调查表就是给组织的顾客抽样群定期(一般为一年1到2次)寄出调查表。
