sample hole 中文意思是什麼
sample hole
解釋
取樣孔-
The working stress of the rc compression member in existing structures can be calculated through measuring strain change before and after drilling the hole, determining the compressive strength and elastic modulus of concrete through the drilled sample and combining the calculating results of the finite element method
該方法通過測試鉆孔前後孔邊應變的變化，利用鉆取的芯樣推定混凝土的抗壓強度和彈性模量，再結合有限元計算分析，得到已建結構中鋼筋混凝土受壓構件的工作應力。 -
When the given point set is a local separate sample of a closed surface set or an overall separate sample with known radius of sampling hole, the algorithm will reconstruct a correct result ; when the separate condition is not satisfied at some points, the algorithm will give result with corresponding holes
當所給點集是閉曲面集的局部分離樣本或已知采樣空洞半徑的全局分離樣本時，本演算法將給出正確的重建結果；當所給點集在某些樣點處不滿足分離條件時，演算法將給出相應的空洞以供參考。 -

井底巖樣抓取器 -
Based on signal from carbon fiber composite defects such as lamination, hole, looseners in ultrasonic testing, this paper performs wavelet packet transform on the ultrasonic signals to extract statistics of approximation coefficients and detail coefficients that contain a great part of signal energy as sample - features
摘要本文以碳纖維復合材料常見缺陷分層、孔隙、疏鬆的超聲波檢測缺陷信號為研究對象，對超聲波檢測信號進行小波包變換，提取包含信號絕大部分能量的近似系數波形特徵及細節系數的統計量作為樣本的特徵值。 -
Through comparative analysis to the test data of tow sampling methods in drilling hole and sampling method in shaft, it was found out by the author that the drilling sampling method has obvious disturbance and depression to the soil sample, which caused the soil sample ' s dry density to be increased, porosity ratio to be decreased, filtration coefficient to be decreased, and modulus of compression to be increased
筆者通過對鉆孔兩種方法獲取的土樣與豎井土樣試驗數據的對比發現，鉆孔取樣對土樣有明顯的擾動和壓密作用，造成了土的干密度增大、孔隙比減小、滲透系數降低、壓縮模量增大。 -
The conducted work in field contained case study area selection, topo survey, sample collection for grain size and mineral composition analysis, bore hole drilling and catching undisturbed soil samples for soil test and microstructure observation, portable cone penetration test, cone penetration test, dynamic penetration test, vane shear test, soil vibration test and hydrodynamic measurement
