between the transducer and the test surface.
When scanning over the part or making precise measurements, an immersion technique is often used. In immersionultrasonic testing both the transducer and the part are immersed in the couplant, which is typically water. This method of coupling makes it easier to maintain consistent coupling while moving and manipulating the transducer and/or the part.
were compared. The third experiment is a free vibration experiment. The experiment was conducted with a system consisting of one spring and a system in which two springs are connected in series. The measured value of the period was obtained through the time it takes for the object to reciprocate 10 times, and the theoretical value of the period was obtained through the given displacement value.

건축외벽과 부지 경계선과의 간격이 좁아서 외벽의 거푸집 작업이나 외벽 시공 후 되메우기 작업이 곤란한 경우 부득이 토류벽과 건축외벽을 합벽으로 시공하게 된다. 이때 흙막이(H-Pile)의 시공오차로 인하여 건축외벽의 단면을 침범
Introduction
Nowadays, the method of chemotherapy + radiation is widely used because it is more effective for cancer cells than normal cells.
However, patient’s quality of life is directly related to the targeting ability of treatment, so that method has some side effects.
So finding less toxic agents and choosing a precise delivery system is a task currently important.
