A photovoltaic pump system based on a new Z-source inverter, whose theory and control strategy of space vector pulse width modulation (SVPWM) with short through states were introduced.
Based on the theory of maximum entropy, MEFS USES mutual information and Z-test technologies, and takes two-step method to execute feature selection.
MEFS在基于最大熵原理的基础上，运用互信息和Z -测试技术，采用两步方法进行空间特征选择。

Z is presently the most fashionable formal specification. But as a whole, the theory and technology of Z specification isn't extensively applied in industry field.
