surface-shear wave 中文意思是什麼
surface-shear wave
解釋
面切波-
In the process of work, according to complex geological conditions such as huge thick soft clay in site and top surface of possible pile foundation supporting course fluctuating in large amplitude, we adopted many advanced exploratory methods ( just as high accuracy exploration of shallow earthquake, crosshole wave velocity test, vane shear test, pressuremeter test, etc. ), we found out that there is an ancient groove of yangzi river in former plant site, therefore we suggested in time that plant site should properly be moved eastwardly, only this item saved nearly about 50 million for pile foundation project cost
在工作過程，根據廠址區軟粘土厚度大、可能作為樁基持力層頂面起伏變化大等復雜地質條件，採取了多種先進的勘探手段（如高精度淺層地震勘探、跨孔波速試驗、十字板剪切試驗、旁壓試驗等） ，查明了原廠址區存在一個長江古凹槽，並及時建議廠址適當東移，僅次一項就節省樁基工程費用近5000萬元。 -
Surface shear wave
表面切變波 -
To utilize property of saws propagating, it can be made including delay lines, passband filters, oscillators and pitch filters. surface transverse wave ( stw ) was used the configurature of reflective metal - strip grating between the two interdigital transducers, and made the shear horizotal ( sh ) wave on the surface of the piezoelectric substrate, but not to deep in
聲表面橫波（ surfacetransversewave ，簡稱stw ）是採用在兩個金屬叉指換能器之間加入短路柵的隔離板結構使剪切水平波（ shearhorizontalwave ，簡稱sh波）被嵌制在壓電基片表面上，而不是沿壓電基片內傳播的聲表面橫波形式。 -
The features of phase and group velocity were advanced by means of preparing samples with different shaping. the phenomenon of " cusp " in group surface of quasi - shear wave ( qsv ) was observed. the inversed velocity surface according to calculated elastic constants in real orthotropic media is consistent with practical measured velocity surface
用加工不同樣品形態的方法給出了正交各向異性介質的相速度和群速度特徵，觀測到各向異性介質群速度面上的尖點現象，並用測試得到的正交介質的彈性常數進行了數學模擬，其波場特徵與測試的速度面特徵相符。 -
In this paper, the reflection method of ultrasonic longitudinal wave and that of ultrasonic shear wave to test the bonding quality of the adhesive interface between steel and concrete from single - surface is adopted respectively
因此，找到一種合理的無損檢測方法來判斷鋼-混凝土粘結質量具有重要的工程意義和實用價值。本文分別採用超聲縱波和橫波反射的方法來單面檢測鋼-混凝土界面粘結質量。 -
Therefore, the solution of the problem can be reduced to a seri es of algebraic equations and solved numerically by truncating the finite terms of the infinite algebraic equations. finally, given two kinds of incident wave and different dimensionless parameters, numerical examples are provided to show the influence of wave number, shear modulus, thickness and distance between the center of the cavity and ground surface upon the dynamic stress concentration by incident steady sh - wave
最後作為算例，給出了第一類和第二類兩種不同的sh波入射方式對襯砌的散射，並選取了兩種無量綱參數值，得出了圓形襯砌對sh波散射的數值結果，討論了不同的波數比、彈性模量比、厚度比以及不同的圓形襯砌中心到水平地面距離與襯砌內半徑的比值對動應力集中系數的影響。
