【正文】 amplifier by adjusting the frequency of vibration can set the frequency according to the piezoelectric vibrator incentives。 oscilloscope to measure the Parts of generating capacity. Since the piezoelectric vibrator support the use of cantilever, the natural frequency of a higher natural frequency for firstorder , and environment of the local oscillator frequency is well below this value, in order to make the frequency of piezoelectric vibrator and the environment of the natural frequency similarity may be in the piezoelectric vibrator additional focus on the quality of the free end of the block adjustment method. Trials, the increase in mass of the weight of grams, that it reduced the firstorder natural frequency . Regulation of power amplifiers, so that the output of a piezoelectric vibrator frequency of , the peak of the sinusoidal voltage of AC (in particular the absence of the following tests are used as criteria), on the electrolytic capacitors, super capacitors and rechargeable batteries in three storage medium for storage parison test. Containing polar electrolytic capacitors, the use of attention should be paid when the connection is negative, the electrolysis electric capacityCapacity can be used as a power supply. At present, the monly used electrolytic capacitors are tantalum electrolytic capacitors and aluminum electrolytic capacitors. Tantalum electrolytic capacitors and aluminum electrolytic capacitors pared to the benefits include: ① small。 ③ long life, high insulation resistance, leakage current small。 ⑤ high reliability. In order to pare the two types of charging characteristics of electrolytic capacitors, are taking the same capacity (100 micromethod) two electrolytic capacitor charging experiment. When external conditions are the same, the same capacity of electrolytic capacitors and tantalum electrolytic capacitors, which charge and discharge characteristics was nearly identical and no significant difference. Although pared to tantalum electrolytic capacitor aluminum electrolytic capacitors, there are many advantages, but it also has its own shortings. There is no electrolyte tantalum capacitor, it is suitable for high temperature work, so the use of metal tantalum medium for voltage, current limited occasions. Tantalum Electrolytic Capacitors Electrolytic Capacitors, as, unlike the ordinary use of the aluminumplated paper firing capacitor, so almost no inductance itself, but it also limited its capacity, at present, the market can buy tantalum electrolytic capacitors, the maximum capacity of only 100 micromethod, the price of aluminum electrolytic capacitors than ordinary expensive, and tantalum electrolytic capacitor voltage and current capacity is relatively weak, piezoelectric power generation is not the best energy storage ponents. In parison, aluminum electrolytic capacitors are cheap, and its larger capacity. In order to better understanding of the storage ，characteristics of electrolytic capacitors, with different capacity aluminum electrolytic capacitors, the chargedischarge test.When the piezoelectric vibrator when a certain output voltage, the electrolytic capacitor charge voltage eventually bee a stable value, that is reaching saturation voltage。 but the capacity of different aluminum electrolytic capacitors, which charge different rates, and the capacitor charging rate with the electric Yung capacity increases. When the initial voltage is the same, differentcapacity aluminum electrolytic capacitor discharge time its different, the discharge time as the capacity of electrolytic capacitors increases. 470 microlaw of the aluminum electrolytic capacitors, the voltage from 3 V down to is more than two hours, it has to meet the demand for certain electronic equipment. To selfdesigned remote control as an example, when the law of 470 microelectrolytic capacitor charging, the charge to the saturation voltage, the remote control can work for 5 times.The abovecapacity aluminum electrolytic capacitors of different charging tests, piezoelectric vibrator in the same opencircuit voltage conditions, piezoelectric vibrator in order to obtain the open circuit voltage of the electrolytic capacitor charging rate relationship test in the same capacity e
