Investigation of analytic potential energy function,harmonic frequency and vibrational levels for the 2~3Σ_g~+ state of spin-aligned dimer ~7Li_2;

An efficient convenient harmonic frequency measurement system is reported in this paper.

Employing the Rydberg-Klein-Rees method,the harmonic frequency is derived from the analytic potential energy function and then o.

Using variable frequency resonance to perform pressure test of 110 kV high-voltage cable;

The validity of on-site variable frequency resonance test for 110 kV XLPE power cable is discussed based on some on-site tests.

Meanwhile,according to the operating method and the existing problems of the Baosteel XLPE power cable on-site withstand voltage test,and combining the current dissimilar standards both at home and abroad,it clarified the application effects of the variable frequency resonance test to XLPE power cable.
