您要查找的是不是：
- At each interface the spreading wave front is made discontinuous. 在每一分界面上擴展的波前出現間斷。
- It starts with zero and grows to a maximum slightly behind the wave front. 它從零值開(kāi)始，并在稍后于波陣面處增長(cháng)到最大值。
- The radii are proportional to the time which has elapsed since the wave front occupied the position wi. 半徑與波前占據wi位置以來(lái)能經(jīng)過(guò)的時(shí)間成正比。
- This assumption is reasonably justified in the early stages, when the wave front is not far from ground zero. 這種假定在初期階段波陣面離地面零點(diǎn)不遠時(shí)是相當合理的。
- If a refraction or a reflecting body is irreqular, the wave front undergoes a deformation. 如果折射體或反射體是不規則的，波前即產(chǎn)生變形。
- The planes of the wave front and the reflecting surface are also normal to the plane of the figure. 波陣面的諸平面與反射面都與圖面垂直。
- If a refraction or a reflecting body is irregular, the wave front undergoes a deformation. 如果折射體或反射體是不規則的,波前即產(chǎn)生變形。
- When the incident wave front reaches this point, the reflected wave is still some distance away. 當入射沖擊波波陣面到達這一點(diǎn),反射波離開(kāi)它還有一段距離。
- High-pressure acting on samples were produced by shock wave front converging in metallic ball. 在該裝置上 ,利用沖擊波由金屬球體表面向中心匯聚形成的高壓 ,對樣品進(jìn)行了沖擊處理 ;
- All elements are radiating in phase, and the resultant wave front is perpendicular to the axis of the element array. 所有單元發(fā)射相位一致，合成的波前垂直于單元陣列軸線(xiàn)。
- Successive wave fronts in this case form a series of concentric spheres. 相繼波前形成了一系列的同心球面。
- Radiation from air shock wave front produced by explosion is an excellent microsecond illuminant. 炸藥爆炸產(chǎn)生的空氣沖擊波陣面的輻射是高速攝影中的一種良好的微秒級持續時(shí)間的照明光源。
- The pressure in wave front is greatly attenuated while the shock wave propagates through the small opening of rocks. 當沖擊波在破碎巖塊間傳播時(shí)，湍流流動(dòng)受壁面的影響很大。沖擊波在通過(guò)孔隙后其波陣面的壓力衰減程度較大。
- In intersatellite communications, wave front aberration is main factor in affecting far-field behavior of signal beam. 星間光通信中,波前畸變是影響信號光遠場(chǎng)特性的主要因素。
- The tension between us has eased off a little. 我們之間的緊張狀況已經(jīng)緩和一些。
- Such wave fronts are seperated from one another by one-half wavelength. 這種波陣面彼此間隔半個(gè)波長(cháng)。
- Such wave fronts are separated from one another by one-half wavelength. 這種波陣面彼此間隔半個(gè)波長(cháng)。
- Relaxation exercises can free your body of tension. 放松運動(dòng)可以松緩身體的緊張。
- The results of simulated calculating shows the validity of projection onto constraints sets (POCS) in controlling wave front propagating. 模擬計算表明,該算法在控制光波前傳播方面是有效的。
- The tension was relieved, the war scare was over. 緊張形勢緩和了，怕爆發(fā)戰爭的恐慌情緒過(guò)去了。
