查询词典 amplitude

As we known, common Loran - C receiver employs a fixed da- tum - mark in order to avoid interference caused by skywave, as the SNR is often poor at this point due to the amplitude limit of the pulse envelope, so it greatly increases time for tracking the datum - mark.

常规接收机为了防止天波干扰，将基准点设置在一个固定位置上，导致基准点处信噪比受包络限制而较低，从而大大增加了对准基准点的时间。

The amplitude or loudness of a sound.

振动幅度的大小决定声音的大小。

The amplitude or loudness of a sound .

音量声音的响度或强度。。。

In the past, the high frequency resonance technique is usually applied in the envelope detection for a vibration signal with amplitude modulation. When applying the Hilbert transform in the high frequency resonance technique for the envelope detection of vibration signals, the computing burden is very high. On the other hand, when applying the linear least squares analysis method, the computing burden is lower. When applying the envelope detection in the lowest vibration mode, an accelerometer with the low-pass filtering cutoff frequency at 4kHz should be choose.

在过去的研究方法中，振动讯号之振幅调变通常以高频解调分析法应用於包络讯号侦测，而高频解调方法应用希尔伯特转换的包络分析，所需要的计算量是非常的高，若以线性最小平方分析法应用於高频解调分析法中，则所需要的计算量较小，如果以最低模态来估测包络讯号时，可以适当的选取加速规来代替低通滤波器，而加速规的截止频带必须在4kHz左右。

Great differences between them are found in amplitude, and attributed to the strong background wind in troposphere and steady weak wind in lower stratosphere. Steady diurnal variation of temperature appears above 23 km, and the same variation in pressure is found starting from lower altitude, which together suggest a weak diurnal variation in atmosphere density above 23 km, that approximates a constant at each height.

发现风场振幅的变化与统计平均的结果存在较大差异，这归结于当地冬季对流层内强烈变化而低平流层内相对稳定的风场；温度在23 km以上存在稳定的周日变化，气压在更大的范围内存在与温度类似的周日变化，这使得在23 km以上大气密度的周日变化十分微弱，在各个高度上近似为一个常数。

Averaging over the main diagonal and sub-diagonals elements of the matrixes, two averaged vectors containing phase information and amplitude information could be obtained.

对矩阵的各主次对角线元素均进行平滑，可得到包含相位信息和幅度信息的平滑向量。

The nonlinear relation of damping versus strain amplitude and frequency is investigated using the AR model and MARM method.

利用喷雾沉积快速凝固技术制备了ZA27合金试样，对铸态及喷雾沉积态ZA27合金的阻尼性能进行了比较。

The mass spectrum of the analyzed ions can be achieved by scanning the amplitude of the RF voltage.

的稳定性中所具有的特性，可实现离子的质谱扫描。经过五十多年的发展，四极杆质谱仪已成为一种技术

The frequency at the point of maximum amplitude is close to the blade passing frequency.

首次分析了不同轴截面的压力脉动，其脉动曲线基本相同。

The probability, the mean value and the standard deviation of the largest response amplitude of the system have been given.

给出了考虑干摩擦时系统最大振幅发生的概率、均值和标准差。

"Yes, now you can give yourself airs," she said, you have got what you wanted.

"对了，您现在高兴了，"她说道，这是您所期待的。

Then the LORD said to me: Rebel Israel is inwardly more just than traitorous Judah.

上主于是对我说：＂失节的以色列比失信的犹大，更显得正义。
