使用专用的探头和探伤仪在较高的增益金量下可探测出某些材料中较小的不连续……至少设想是如此（图40），而且只用增益金量就可判定出超高检验装置的性能。图40较高的增益金量Vr有较好纺裂纹可探测性因为声散射未起到一个极重要的作用，完全证实了这个假定是正确的（图41）。
The use of a dedicated probe and flaw detector can detect small discontinuities in some materials at higher gain levels ... at least as envisioned (Figure 40), and the use of gain gold alone can determine ultra-high Verify device performance. Figure 40 The higher gain gold Vr has better spun crack detectability. This is fully validated because acoustic scattering does not play an important role (Figure 41).
