查询词典 envelope detector

But with its variety and specialization , three-axial non-instaneous envelope method had not meet needs. So four-axial non -instaneous envelope method was set forth firstly in this article, which is based on three-axial non-instaneous envelope and spiral rod compressor rotator speciality.

然而随着螺杆应用范围的扩展，螺杆型线不断复杂化、多样化，三自由度无瞬心包络铣削法已不能满足部分型线的加工要求，为此本文在三自由度无瞬心包络铣削法的基础上，针对螺杆压缩机阴阳转子的特性，在国内首次提出四自由度无瞬心包络铣削螺旋曲面的新方法，赶超国际螺旋曲面加工技术水平，具有重要的理论和现实意义。

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。

One summer they planned to fly to New York fo their holidays.They got to the airport only ten minutes before the plane left.So time was short,but suddenly Mrs.Long said she must tell Linda,their daughter,not to forget to lock the front door when she went to school.As Linda was then at school,they couldn't tell her about it by telephone.So the couple hurried to the post office.Mrs.Long wrote a short note to Linda while Mr.Long bought a stamp and an envelope.Soon the note was ready .They put the stamp on the envelope in a hurry and put it in the letter box.But suddenly Mrs.Long began to cry.The short note was still in her hand.She had put the plance ticket in the envelope!

一个夏天他们计划飞往纽约度假，他们在飞机离开前仅十分钟才到了飞机场，所以时间很短，但是突然Long太太说她必须去告诉他们的女儿Linda，当她上学时不要忘记锁自家的前门，现在女儿正在学校，他们不能用电话告诉女儿，所以这对夫妻很快去了邮局，当Long先生买了一枚邮票和一个信封时，Long太太写了一个小纸条给Linda，很快纸条写好了，他们很快把邮票贴在信封上，之后把它扔进信箱里，但是突然Long太太开始哭，那个小纸条还在他的手上，她已经把机票放在了信箱了！

By computing chiefly the temperature field on the sensitive film of the detector, the influence of different sizes of detector constructions upon some performance parameters is analyzed to optimize the design of a bolometer detector.

主要通过对探测器敏感层温度场的计算，考虑探测器结构尺寸对其性能参数的影响，起到优化设计的作用。

Under the condition of the borehole and sandstone formation filling with oil and water, respectively, the ability is different when different energy windows are selected to distinguish formation by simulating the detector response spectrum of various diameters and length of NaI and BGO crystal. The C/O value difference of BGO crystal is higher than that of NaI crystal when the energy window includes photoelectric peak, the first and the second escape peaks, but it is less affected by the different sizes of detector crystal. Using photoelectric peak corresponding to the energy window, the C/O value difference of BGO crystal detector is much larger than that of NaI, but it increases with the crystal size increasing. The C/O value is greatly affected by energy drifting, while relatively a little by energy resolution.

对于井眼和地层流体分别为油和水砂岩地层，模拟改变NaI和BGO晶体探测器的直径和长度时的非弹性散射γ射线响应能谱，采用不同能窗处理方法对地层流体的分辨能力不同，选取光电峰和第一、第二逃逸峰对应的能量窗时，BGO晶体探测器比NaI晶体探测器测量的C/O差值大，但受尺寸的影响不大；采用光电峰对应的能量窗时，BGO晶体探测器测量的C/O差值比NaI的大得多，且随尺寸的增加差值增大；能量道的漂移对C/O值影响较大，而能量分辨率对差值影响相对较小。

The second is to cut a mere 100 calories from your diet , which is the equivalent of a tablespoon of butter.
