你有太多的打字錯誤, 再幫你整一點, 有事去了:

Any test circuit corresponding to that of figure 1 can be used to make the measurement of EBLF The luminous flux of a lamp is usually measured with an integrating photometer For ratio measurements of lumious fluxes a suitable illuminance meter is sufficient as there is a close ralationship between luminous flux and illumination at a fixed point
