    摘要:

    介紹了可適用鈦金屬０．４ｍ～１．２ｍ不同焦距，微粒膠片Ｘ射線照相用的ＫＵｐ－Ｔ－Ｆ新型曝光曲線的制作原理及方法，試驗(yàn)結(jié)果表明，新型曝光曲線具有制作簡(jiǎn)便，經(jīng)濟(jì)實(shí)用，可兼顧底片象質(zhì)和拍片效率的優(yōu)點(diǎn)，是鈦制壓力器現(xiàn)場(chǎng)變焦距透照選取準(zhǔn)確管電壓值的理想工具。

    Abstract:

    The principle and method of plotting new kUP (tube voltage)T(thickness of specimen)F(focal distance) exposure curves for the use of radiographic examination of Ti with focal distances of 0412 m are described. The test results show that the method of plotting the kUpTF curve is not only simple, economical and practical, but also good for the image quality of the photographic plate and the photographic efficiency. The curve is also ideal for choosing an accurate value of tube voltage for the onsite radiographic examination of Ti pressure vessels.
