您要查找的是不是：
- pure sinusoidal oscillition 纯正弦振动
- Suppose the speakers both emit a pure sinusoidal sound wave of constant frequency. 假定两个扬声器都发射恒定频率的纯正弦声波。
- This shows how a pure frequency e.g. a pure sinusoid, which is an impulse in the frequency domain is spread out across frequency when it passes through the channel. 不过，在有些情况下，研究者只对幅度的波动感兴趣。针对这种情况，有两种方法可以仿真产生瑞利衰落信道。这两种方法的目的是产生一个信号，有着上文所示的多普勒功率谱或者等效的自相关函数。
- Previous studies have shown that the MDCT analysis results of pure sinusoids can be approximated by using the product of a constant, a cosine function, and a decay function. 由先前的研究，一个正弦波讯号的修正式离散馀弦转换分析结果可以由一个常数，一个馀弦函数与一个衰减函数的乘积所逼近。
- It was pure luck that he was home when we called. 非常幸运，我们打电话时他在家里。
- Suppose the speakers both emit a pure sinusoidal sound wave of constant frequency 假定两个扬声器都发射恒定频率的纯正弦声波。
- I have the pure heart of a newborn baby. 我有一颗赤子之心。
- We must not condemn her on pure supposition. 我们不能单凭猜测就谴责她。
- Don't believe what he's saying it's pure bunkum. 别相信他的话--纯粹是胡说八道。
- A long hot bath can be pure luxury. 洗个痛快的热水澡可真是一种至高的享受。
- The fields were all covered with pure white snow. 白雪皑皑，铺满田野。
- These models use a simulated input transducer that vibrates purely sinusoidally with a fixed frequency. 这些模型采用一个模拟输入探头，以完全正弦波的形式按固定频率振动。
- The condition or quality of being pure or chaste. 纯洁纯洁或贞洁的状况或者品质
- That new lamp they've bought is pure kitsch. 他们新买的那盏灯真俗气。
- Besides, it's make of pure wool, very soft. 另外，这是纯羊毛的，手感柔和。
- It's make of pure wool, very soft. 这是纯羊毛的，非常软。
- Sorry I hit you; it was a pure reflex. 对不起我撞著你了; 这完全是无意的。
- You think that, do you? Pure illusion! 你是那麽想的吗? 纯粹是错觉！
