line of incidence
解釋
入射線-
The angle drawn at the point of incidence ( intersection of ) a reflected ray and the normal line perpendicular to the reflecting surface
中義光線在物體表面的投射點上反射出來的光線與物體表面垂直法線所夾的角度。 -
The conclusions are as follows : the ultrasonic intensity is proportion to the laser intensity ; the ultrasonic induced by a laser line source has much more advantages than by a laser point source, such as stronger energy, higher snr, more directivity and shape ; the intensity of cfpi ' s output signal is linear with ultrasonic vibration velocity, and is effected by incidence angle and scattered angle ; snr will increase by reducing cfpi ' s bandwidth, reducing incidence angle, increasing cavity ' s length and reflectivity
在分析點光源激勵聲表面波機理的基礎上，求出了線光源激勵的超聲振動的位移表達式，發現線光源激勵的近場區表面波具有波形好，信噪比高，指向性好，幅度強等特點。通過理論推導，得出共焦fabry - perot干涉儀的輸出光強除了與樣品表面的振動速度成正比，並與入射角和散射角有關；適當減小cfpi的帶寬，增加腔長，增大鏡面反射率，或者減小檢測入射角都可以提高系統的信噪比。 -
In the situation of the rarefaction chasing after the shock wave, both the analysis solve and the important relation as to the characteristics of the wave form are obtained in the use of the characteristic line method before the rarefaction catching ip with the shock wave ; after thai, qualitatively, two kinds of wave forms, reflection shock wave and incidence shock wave, or reflection shock wave and incidence rarefaction, may be obtained as well as the corresponding conditions for their occurrence
對稀疏波追趕沖擊波的情況，在稀疏波趕上沖擊波以前，利用特徵線方法，得到了此問題的解析解及有關波形特性的重要關系；在稀疏波趕上沖擊波以後，不僅定性地得到二者經過相互作用以後，可能產生的兩種不同波形，即反射的沖擊波和入射的沖擊波或者反射的沖擊波和入射的稀疏波，而且給出了產生不同波形所對應的條件。 -
Study on the relationship between the level of inter - iliac - crest line and the incidence of low lumbar disc prolapse
髂嵴間線水平與低位腰椎間盤突出發生率的相關性研究 -
I achieve approximately the increment of sound level in sound focusing region relative to sound incidence ( ? lpc ), and make ascertain the sound pressure level in focusing region accurately. through draw the curve of wrap - up line equation with matlab program of computer software
文章最後總結出本文理論分析所得的幾個解析式和避免聲聚焦的設計原則，同時在理論和實驗上提出今後研究其它構造時的一些方法和方向。 -
As the change of the extension of mean life and social living conditions, coronary heart disease has in the incidence of a disease of our country increase a current, the coronary heart disease in patient of bravery line operation the person is corresponding also grow in quantity
隨著平均壽命的延長和社會生活條件的變化，冠心病在我國的發病率有增加趨勢，膽道手術病人中冠心病人也相應增多。
