摘要： PROBLEM TO BE SOLVED: To provide a non-destructive inspection method suitable for inspecting the presence or degree of the flaw in a specific target region, and a non-destructive inspection device.
SOLUTION: An incident wave is sent to the piercing part 2a (specific target region) of the metal pipe 2 piercing a wall 1 from an actuator 3 to produce the standing wave w due to the interference with a reflected wave. Since the intensity of a transmitted wave decreases and the intensity of the reflected wave increases when a flaw part 2b such as corrosion is present in the piercing part 2a, the amplitude in the node w' of particle velocity becomes small. Meanwhile, since the piercing part 2a is healthy in the case where there is no flaw part, the intensity of the transmitted wave is large and the intensity of the reflected wave becomes small while the amplitude in the node becomes large (a standing wave ratio becomes small). That is, the standing wave is produced in the metal pipe on this side of the wall 1, the acoustic impedance in the piercing part 2a of the wall is calculated by detecting a standing wave mode and the distance degree of the value of the acoustic impedance from a health value is known to determine the presence of the flaw in the piercing part 2a of the wall.

摘要翻译：要解决的问题：提供适合于检查特定目标区域中的缺陷的存在或程度的非破坏性检查方法以及非破坏性检查装置。解决方案：将入射波发送到从致动器3刺穿壁1的金属管2的穿孔部2a（特定目标区域），由于与反射波的干涉而产生驻波w。由于当穿刺部分2a中存在诸如腐蚀的缺陷部分2b时，透射波的强度降低，反射波的强度增加，所以粒子速度的节点w'中的振幅变小。同时，由于穿刺部分2a在没有缺陷部分的情况下是健康的，所以透射波的强度大，并且反射波的强度变小，而节点的振幅变大（驻波比变为小）。也就是说，在壁1的这一侧的金属管中产生驻波，通过检测驻波模式和声阻抗值的距离度来计算壁的穿刺部分2a中的声阻抗已知从健康价值来确定壁的刺穿部分2a中的缺陷的存在。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an acoustic capacity measurement method for finding capacity of a container and an object or the like by removing effect of a surface area without using an approximate expression of acoustic impedance.
SOLUTION: The acoustic capacity measurement method acquires the capacity of the container under test by the pressure change ratio, giving equal alternating capacity change to a reference vessel and the container under test, and detecting the pressure change of the reference vessel and the container under test due to the pressure change. This method includes a pressure change ratio calculating step which calculates the pressure change ratio between the reference vessel and the container under test, a rotation step which calculates an acoustic admittance component of the container under test by rotating the calculated pressure change ratio by angle θ so as to change a gradient 1 for the change of the surface area on a complex plane, an oblique coordinate transformation step which transforms the acoustic admittance component into the oblique coordinate system consisting of an imaginary axis and a straight line of the gradient 1, a capacity calculating step which calculates the capacity of the container under test by multiplying the value in the direction of the imaginary axis of the acoustic admittance component transformed into the oblique coordinate by a predetermined real number.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for testing leakage, capable of eliminating temperature induced fluctuations for pressure changes of fluid in piping or a tank in response to situational changes with respect to a pressure type of leakage test.
SOLUTION: An adaptively estimating section 161 adaptively estimates a temperature-induced pressure component y(t) shared in a pressure signal ΔP(t) based on the pressure signal ΔP(t) and a temperature signal x(t). A subtracting section 162 determines a temperature-compensated pressure (error signal e(t)) subtracting the temperature-induced pressure component y(t) from the pressure signal ΔP(t). A control determining section 17 performs the leakage test of the piping 2 based on changes of the temperature-induced pressure. Accordingly, even if, for example, a temperature distribution of the fluid in the piping 2 is present and momentarily changes, and the heat characteristics of the piping 2 are unknown, the temperature induced fluctuations for the pressure changes of the fluid can be eliminated adaptively and securely at high precision.
