axial drop 中文意思是什麼
axial drop
解釋
軸向壓力降-
The hydrodynamic propulsor takes drill fluid as power source, with the aid of the axial load produced by the pressure drop of the bit nozzle, makes the axial force act on the bit to produce wob, making up for the insufficient wob, ensuring the bit feeding smoothly and improving the penetration rate
這種推進器以鉆井液為動力源，藉助鉆頭噴嘴壓降產生的軸向載荷，使軸向力直接作用於鉆頭產生鉆壓，彌補有效鉆壓不足，保證鉆頭平穩鉆進，提高機械鉆速。 -
Using the system designed in this thesis work, flow field calibration of the wind tunnel is accomplished, which covers dynamic pressure drop coefficient, dynamic pressure time stability, axial static pressure gradient, boundary layer, and degree of turbulence, etc. boundary layer measuring principle and method are especially described in detail, the relationship between boundary layer thickness, wind speed setting, and the depth of the experimental section is summarized, and finally the calibration data for th e model center zone under specific wind speed are given
然後利用本文設計的系統完成了落差系數、動壓時間穩定姓、軸向靜壓梯度、邊界層及湍流度等內容的流場校測。特別對邊界層測量的原理及方法做了較詳盡的敘述，總結出邊界層厚度與設定風速、實驗段深度的關系，然後給出模型中心區一定風速下校正數值。 -

The results show that the improved structure has obviously reduced pressure drop and increased axial speed of the nozzle, as a result the wallop of electroplating solution is improved and the thickness of diffused layer reduced, the electrodeposition process improved, and what is more, the coating structure has been compacted, crystalline particles fined and the performance improved
結果表明，結構改進后，明顯減小了壓力損失，提高了噴嘴的抽向速度，電鍍液沖擊鍍件的沖擊力得到提高，有效地減少了擴散層的厚度，改善了電沉積過程，而且使鍍層組織緻密，晶粒細化性能得到提高。 -
Test method for axial pull connector drop cable
軸拉連接器用戶引入電纜的試驗方法 -
The experimental results are the following : 1 the resistivity changing features of rock show rise - smooth - drop, and the smooth segment is very short and unobvious. 2 the time of first drop for the apparent resistivity is earlier than all other loading experimental results, the rupture stress about moves up by 10 per cent. viz : the apparent resistivity starting drop when axial rupture stress increases about 40 per cent for the array parallel to the axial ; the apparent resistivity starting drop when axial rupture stress reaches about one - third for the arrays non - parallel to the axial
即：平行於軸壓方向的測道，在軸向破裂應力的40 %左右開始下降不平行軸壓方向的測道，視電現率約在1 3軸向破裂應力開始下降3電阻率從開始下降起，下降速率逐漸增加，但增加得很緩慢，巖石大破裂前，單位軸向應力變化引起的視電阻率變化幅度也不是很大。
