3. They pointed out that modulation wave fronts ( such as those in the front of a light pulse ) in a negative index material are aligned the same way as they are in a positive index material ? anything else would violate basic causality and require parts of the wave to travel with infinite velocity
   他們指出在負(fù)折射率材料中調(diào)制波前（例如光脈沖前端的波前）的方向，與在正折射率材料中相同；若非如此，就會違反基本因果律，且部份波的前進(jìn)速度將成為無限大。
4. Transmition velocity relys on the style of encode and modulation essentially during modern data transmition for the quality of using line bandwidth and the immunity of code ties on them tightly . but it is important that the velocity of data transmition reaches its limitation in fact for the interface of environment and cross - talk . so for the improvement of transmition velocity , we must analyze the characteristics of noise signal and the model of line deeply and then take some useful measures to better the immunity of modulation wave
   在現(xiàn)代通信的數(shù)據(jù)傳輸過程中，傳輸速率本質(zhì)上是由傳輸?shù)木幋a方式和調(diào)制方式?jīng)Q定的，因?yàn)榫幋a方式和調(diào)制方式直接決定了線路頻帶利用率和碼元抗干擾能力的好壞，因而直接決定了傳輸速率；但是在實(shí)際應(yīng)用過程中，數(shù)據(jù)傳輸速率是不可能達(dá)到理想狀況的，因?yàn)榄h(huán)境干擾、串音干擾等因素的存在使得線路的頻帶不可能被完全利用起來；因此，必須認(rèn)真分析線路的噪聲信號的特性以及噪聲線路的模型，以便在編碼方式和調(diào)制方式中針對性的做一些改進(jìn)措施以改善調(diào)制波形的抗干擾能力，使得傳輸速率能夠進(jìn)一步提高。
5. The general signal sources represented by arbitrary waveform generator ( awg ) have become the most popular instruments in modern testing domains . awg can not only generate conventional waves such as sine wave , triangle wave , square wave , etc , but also generate unconventional waves such as linear frequency modulation wave , phrase modulation wave , amplitude modulation wave etc , the most important , it can create arbitrary wave
   由于它可產(chǎn)生包括各種理想及非理想的波形信號，不但可以產(chǎn)生純凈的正弦波、方波、三角波等常規(guī)波形，而且可以產(chǎn)生線性調(diào)頻、調(diào)相、調(diào)幅信號以及程控占空比的低占空比方波，更為重要的是，能夠根據(jù)用戶測試需求生成任意波形。
6. It's difficult to find modulation wave in a sentence. 用modulation wave造句挺難的
7. The nucleus is the software in the design and realization of virtual instruments . we use the design method of module and use many papers to describe the whole building process of the typical signal generation module , date handling module , date reading and writing module , resultdemonstrate module . as the conclusions , we also offer the panels and the diagrams of virtual signal frequency spectrum analytical instrument , virtual butterworth filter , virtual signal generation instrument , virtual integrator and differentiator regulator and amplitude modulation wave counter modulation instrument
