In the second part, the current-voltage characteristics of the sensors were measured, their charge ionic mobilities were measured with polar inversion method and their ionic numbers were computed. It has found that ionization effect of some binding ions against a critical humidity took place in switchable humidity-sensitive materials, the effect is that some binding ions in materials turn into free ions when a given ambient humidity is reached called a critical humidity, avalanching conduct electricity occurs in materials.

在第二部分中，测试了高分子电阻型湿敏元件和开关型湿敏元件的伏—安特性，并用极性反转法测试了其导电离子的迁移率以及计算了相关的导电离子数目，发现了开关型湿敏元件的束缚离子的最小湿度电离效应：当环境湿度达到或者大于一特定湿度时，这一特定湿度称之为最小湿度，材料中某些束缚离子才电离成自由的导电离子，形成雪崩式导电。

This article introduced the manipulator, it outputs four groups by PLC to actuate the abscissa axis, the z-axis, the chassis rotation, hand-rotating motor separately, and controls the manipulator abscissa axis and the z-axis pint pointing, the micro switch bequeaths the position signal to the PLC main engine; The electrical machinery drives the hand fingernail and the chassis revolve; The solenoid valve controls air valve the switch to control the manipulator hand fingernail to gather, then realizes the manipulator proper motion function.

Self-protect, press the seset button quickly (nit more than 0.1 second), turn on the illumining switch.if the led lighting normally, the system resume normal. if the led light blinks, turn the swith to off, and then press the seset button .if the led light turns dark, the module need to be charged.

模块自保护，可短按顶部的复位按钮（按下时间不能超过0.1秒），打开照明开关，如LED正常发光，即功能己恢复正常，如照明LED不能正常跟光，请先顶部开关拔至&OFF&，再短按复位按钮，如，LED光明显变暗，表示本电能模块需补充电量了。

Turn off the transportation switch and have the lamp insolated for2 days before first using it.

第一次使用时必须关闭运输开关暴晒两天后再打开运输开关使用。

Intelligence power: the driver steps down the accelerator pedal to intelligence power switch and continue to step it down with bigger force when the vehicle needs accelerating and overpassing other vehicles, the accelerator pedal will press down the intelligence switch when the accelerator exceeds the normal full accelerated position; now the engine will emit higher power than rated power in a short time, so the vehicle will get a stronger acceleration.

智能动力：当车辆需要加速超车时，司机踩下油门踏板至智能动力开关，并继续以较大的力往下踩时，油门超越正常的全油门位置，将智能开关压下，此时发动机会短时地发出比标定功率更高的功率，车辆因而获得更加强劲的加速性。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
