Oscilloscope is an electronic measuring instrument which is used in production practice and scientific research widely. Ordinary oscilloscope have heavy exterior and single function, and we can't measure the signal amplitude ...

The sptitching measuring method applied in large-aperture aspheric surface optical elements can expand the range of precision measuring instrument. And the key point is developing the technique for high precision measuring ...

The effect of light intensity and temperature on the performance of InGaN solar cells were investigated experimentally. With the increase of light intensity, the short circuit current density (Jsc) increases linearly and ...
