amplitude of pressure change 中文意思是什麼
amplitude of pressure change
解釋
壓力變化幅度-
With the pressure in the simulated right ventricle ( srv ) and simulated left ventricle ( slv ) kept constant ( standard pressure condition for model iii ), each step of pressure decrease in the scc from 0 mmhg to - 5 mmhg, the sivs moved leftwards ( to the slv direction ) in a corresponding position and from 0 mmhg to + 5 mmhg, the sivs swung left - and rightwards at amplitude of 2. 2 mm. effects of intrathoracic pressure change on the motion of ivs under the same simulated respiratory
胸壓變化對室間隔運動的影響當模擬右心室和左心室壓力一定時，模擬胸腔內壓力每一次下降（從到一smmhg人模擬室間隔均向左側移位；當模擬胸腔內壓力相同，隨模擬右心室壓力的升高，模擬室間隔的運動幅度增大，當模擬右心室壓力升高到與模擬人心室相等時，模擬室間隔的運動幅度達最大。 -
Along with increase of pressure, the parameters such as velocity, amplitude, main frequency and quality factor of seismic wave change big gradually, while change very weakly with the change of temperature. through testing research for artificial crack and pore model, we conclude that crack density, azimuth, opening and the change of pore have obvious influences on speed, amplitude, attenuation ( or quality factor ) and main frequency of seismic wave etc. but, seismic wave dynamic characteristics are more evident than its kinematical characteristics for the change of crack and pore parameters. therefore, it offers reliable experiment foundation for detecting crack and pore by seismic wave kinematical characteristics ( such as amplitude, attenuation and main frequency etc. )
通過對人工裂縫和孔洞模型的超聲波實驗研究，可以認為：裂縫密度、方位、張開度和孔洞密度的變化對縱橫波的速度、振幅、衰減（或品質因子q ）和主頻率等參數均有明顯的影響，但裂隙參數的變化對地震波動力學特徵參數（振幅、衰減、主頻率等）的影響遠遠大於對運動學特徵參數（速度等）的影響，這為利用地震波的振幅、衰減和主頻率等屬性參數進行裂縫和孔洞特徵的檢測提供了可靠的實驗基礎。 -
Resonant devices are used to measure strain, stress, acceleration, pressure, mass, flow, etc. by detecting the change of the resonant frequency or amplitude of the resonant components
諧振器件通過檢測振動元件的諧振頻率或振幅的變化來測量應變、應力、加速度、壓力、質量變化以及流量等，廣泛應用於力學量傳感器中。
