求翻译：随着温度和水分含量的升高，交叉频率增大，而且水分含量越大、温度越高，交叉频率的增大趋势越明显，因此可以通过交叉频率的变化来评估变压器油纸绝缘的状态是什么意思？

With the rise of temperature and moisture content, the crossover frequency increases, the greater the moisture content, the higher the temperature, the increasing trend of the crossover frequency, the more obvious, so you can change through the crossover frequency to assess the state of transformer

As the temperature and moisture content increases, the crossover frequency, and that the greater the moisture content, the higher the temperature, the crossover frequency, the more obvious tendency toward higher through crossover frequency can be changed to evaluate the state transformer greaseproof

Along with the temperature and the moisture content ascension, the crossover frequency increases, moreover the moisture content is bigger, the temperature is higher, the crossover frequency increases the tendency to be more obvious, therefore may appraise the transformer oil paper insulation through
