解釋
準激波-
According to the correlative theory of hydromechanics and shock wave, theoretical model of creating quasi - isentropic compression via w - mo - ti - mg system flier - plate with graded wave impedance was established, and study on the numerical simulation of the impact process was then carried out
根據流體力學和沖擊波理論知識，首先建立了梯度飛片擊靶的理論模型，對w - mo - ti - mg系梯度飛片擊靶過程進行了數值模擬計算。 -
The initial velocity jump and velocity peak of the quasi - isentropic waves are greatly concerned with shock wave impedance of the targets. changing the impact conditions, there are evident differences among the quasi - isentropic energy
隨著擊靶速度的提高，準等熵壓縮波的波陣面前沿的上升時間逐漸減小，而對應的速度峰值和初始跳躍則不斷增加。 -
The results showed that quasi - isentropic compression energy waves were produced after the impact with mg - face of the flier - plate, whose initial velocity jump, peak velocity and front ' s rise - time were all different from the general shock loading wave profiles
結果表明，梯度飛片正向擊靶后產生的是波陣面明顯被展寬的準等熵壓縮波，準等熵壓縮波的初始速度跳躍、速度峰值和波陣面前沿的上升時間都呈現出不同於傳統沖擊波陡峭上升波形的特徵。 -
The physical process of generating quasi - isentropic compression on target via flier - plates with graded wave impedance might be considered as the successive overlap of a series of small shock loading waves generated by the transition layers in the flier - plate. as a result, the p - v curve of the target was a quasi - isentropic compression curve, which consisted of small hugoniot curves ( similar to isentropic curves ) from different original states, and was located between the hungoniot curve and isentropic curve but closer to the latter
波阻抗梯度飛片對靶板的壓縮過程是一系列弱沖擊加載波相繼發生作用疊加的結果，靶板由此獲得的p - v線是一組通過不同起始狀態點的hugoniot線的連線，這條連線可以近似看作是由小段小段等熵線連接而成的準等熵線。 -
The results showed that quasi - isentropic compression energy waves were produced after the impact, whose initial velocity jump, peak velocity and front ' s rise - time were all different from the general shock loading wave profiles. furthermore, the higher the impact velocity, the smaller the extended wave ' s front while the higher the peak velocity
結果表明，梯度飛片擊靶后產生的是波陣面明顯被展寬的準等熵壓縮波，準等熵壓縮波的初始速度跳躍、速度峰值和波陣面前沿的上升時間都呈現出不同於傳統沖擊波陡峭上升波形的特徵。 -
The results show that, the process of quasi - isentropic compression on target can be seen as the successive overlap of a series of small shock loading waves generated by the transient layers. the design for flier - plates with graded wave impedance should conform to the parabolic or cubic function relationship between the impedance and the thickness
波阻抗按高冪次函數（冪次在二次至三次之間）分佈的梯度飛片能夠獲得波形較好的準等熵壓縮波，並且靶板的厚度不宜太小也不宜太大。
