step conductance

System detects output voltage and output current of the PV array, compares conductance increment of photovoltaic array and instantaneous conductance, then changes the duty cycle with variable step length, achieves maximum power point tracking fast.

系统检测光伏阵列的输出电压和输出电流，并通过比较光伏阵列的电导增量和瞬间电导变步长改变占空比，实现对最大功率点的快速跟踪。

It takes stress monitoring a step further than most by tracking skin temperature, movement, sleep, respiration, heart rate, heart rate variability and skin conductance, a measure of electrical charge that reflects changes in arousal.

这种设备在压力监测方面比大多数同类产品更胜一筹，因为它跟踪了皮肤温度、运动、睡眠、呼吸、心率、心率变异性和皮肤电导性（反映唤起状态变化的一种电荷指标）。
