| 释义 | waveform noun[ C ] physics specializeduk /ˈweɪv.fɔːm/ us /ˈweɪv.fɔːrm/ the curved shape of a graph(= a picture showing how two sets of information are related) that shows a wave (= the pattern in which some types of energy move): 波形 The heartbeat is measured so that various features of the waveform can be used to identify the individual whose waveform is being analyzed.通过测量心跳，可以利用波形的各种特征来识别接受测量的个体。 A microphone converts an acoustic waveform consisting of alternating high and low air pressure travelling through the air into a voltage. The waveform of this current is shown in Fig. 2. Scott had recorded the sound waves together with waveforms from a tuning fork vibrating at a constant frequency of the musical note A above middle C. He was peering in some confusion at an arc of screens which pulsed with read-outs and rippling waveforms. Physics: energy, force & power animal magnetism anti-gravity atmospheric pressure attract attraction ballistic entropic entropically equilibrant erg excited geothermal inertia preatomic propulsive radiant energy self-propulsion sine curve the sound barrier thermodynamics Examples of waveformwaveform There are banks of storage for the waveforms, envelopes and pages. The rotary devices used offset weighting which generated sinusoidal waveforms throughout the frequency range. Effects specific to the memory and control tasks, other than the effect of probe status, were approximately canceled in these difference waveforms. The site was at once very personal, in that the waveforms reacted differently in each individual. An architecture for lossy compression of waveforms using piecewise-linear approximation. Voltage waveforms were therefore used for measuring spectra because of the more rapid data processing. The averaged evoked (or event related) potential is assumed to consist of spatially and temporally overlapping waveforms generated by different neural systems. However, grand-average waveforms can be visually deceptive and give the appearance of group differences that are not actually present. Typical temporal waveforms of the incident and reflected waves without pre-pulse. I show below representative waveforms and spectrograms of the relevant tokens. In that case, one can consider the energy and the spectral extent of the waveforms which are directly related to the modulation index. To the more advanced student, the drawing of waveforms also presents a few problems. Our spectrograms and waveforms have illustrated this type of relationship. Learning features and segments from waveforms : a statistical model of early phonological acquisition. The gray waveforms represent responses before addition of the last drug in the combination. See all examples of waveform These examples are from corpora and from sources on the web. Any opinions in the examples do not represent the opinion of the Cambridge Dictionary editors or of Cambridge University Press or its licensors. |
