sonic speed 中文意思是什麼
sonic speed
解釋
聲速-
A sonic boom is the loud crash and shaking that happens when a jet plane goes faster than the speed of sound
聲爆是當噴氣式飛機超音速行駛時產生的巨大碰撞和搖動聲。 -
If the burrow is in devon, that implies a cruising speed of 900 m. p. h. ? so the sonic boom would make them highly conspicuous even if they were invisible
如果陋居在德文郡，那意味著900英里每小時的巡航速度? ?因此即使他們是看不見的，音爆會使他們非常顯著！ -
Non - uniformity of the amplifying effect and dimension of the slope are pointed out through analysis of the distribution of the stress and sonic speed in the slope. forms of slope lost stability resulted from blasting vibration are analyzed and appraising rules of slope stability are summarized by a great deal instances on coasts. based on general discussion about calculation methods of the slope stability under the effect of blasting vibration, the synthetical method, a new one, is put forward, analyzed through a sample by and pointed out which is one of most valid methods
利用波動理論，得出延期時間為nt / m時減震效果最好；在分析邊坡巖體內部應力、質點速度等分佈規律的基礎上，指出邊坡震動放大效應的不均勻性和邊坡尺寸效應；結合大量滑坡實例，分析了爆破震動引起邊坡失穩破壞的幾種形式，總結出邊坡穩定性評價準則；基於對邊坡穩定性計算方法的綜合分析，提出了一種綜合分析方法，通過算例計算分析，證明該法計算精確度高、功能全面，是邊坡動力穩定性分析的有效方法之一。 -
The criterion to judge the relaxation depth of rock mass of excavation slope is defined by analyzing data of sonic wave speed and field investigation, and the distributing law of various weathered degree fossil weathered rock on slope of are educed. the mechanics parameters of relaxed rock mass are studied by using relational expression between mechanics parameters and value of sonic wave speed, which provide convenience for the study of mechanics parameters of rock mass in different state
在此基礎上，利用現場調查和實測波速資料，制定了邊坡開挖巖體鬆弛帶深度的判定標準，從而分析得出了各風化程度古風化巖邊坡的鬆弛帶分佈規律，並採用波速與巖體力學參數的相關式對鬆弛帶巖體的力學參數進行了研究，為研究不同狀態下巖體的工程特性提供了方便。
