稳压二极管

I am engaged in diode, triode, voltage regulator tubes Product research, development, and production and supply, with the most advanced production equipment and strong technology development strength and experience of large-scale production.

我公司从事二极管，三极管，稳压管产品的研究，开发，及生产及供应，拥有最先进的生产设备和雄厚的技术开发实力及大规模生产经验。

Client software development is introduced with the example of zener diode tester software design, and multiple threads technology is explained emphatically.

以稳压二极管测试仪的软件开发为例介绍了客户端的软件开发，着重介绍了多线程技术的应用。

In the modern electronic circuit instrument and the equipment, took the voltage datum the zener diode, has a more widespread application.

中文摘要：在现代电子线路仪器和设备中，作为电压基准的稳压二极管，有着较广泛的应用。

In the original I used a 9 volt zener diode instead, but I figured it's harder to get zeners. The circuit will work without the diodes.

在图中我画成了整流二极管，实际使用9V的稳压二极管，没有保护二极管电路也能正常工作。

The TTL_BUFFER using the voltage stabilizing characteristic of the Zener diode causes the variation of input voltage with voltage reference to be about 1V and improves the precision of the voltage reference.

利用齐纳二极管的稳压特性，构成TTL_BUFFER缓冲电路，使基准电路的输入电压变化范围在1V左右，从而提高电压基准精度。

Its possible causes are: the transistor operating point is not the choice of a good, high-voltage filter capacitor leakage or damage, leakage heat regulator diode, rectifier diode damage.

其可能原因有：晶体管工作点未选择好，高压滤波电容漏电或损坏，稳压二极管发热漏电，整流二极管损坏等。

From the use of points, and voltage regulator rectifier switch photoelectric detector such as varactor diode; diodes with unidirectional conductivity.

从用途上分，有整流稳压光电开关变容检波等二极管；二极管具有单向导电性。

Was founded in 1998, the main distribution line agents and flake-like electronic components, has Huake, thick sound, YAGEO resistance, Howard Branch, YAGEO, Samsung, TDK's capacitor, the United States AVX and KEMET, Japan NEC tantalum capacitor, NEC, PHILIPS, MOTOROLA, long electric brand b / triode, ST and ROHM's regulator tube, TOREX, Pui Ling, Li Qi, Jing-fu, Taiwan's power supply LDO regulator IC, DC / DC step-up IC, DC / DC step-down IC, TDK, too enticed, Fenghua inductor, bead, Panasonic adjustable capacitance, an adjustable resistor, three-ying Korea and Japan's Sanyo electrolytic capacitors, and insurance management, light-emitting diodes, thermistors, varistors, the brand of integrated circuits and so on; are a professional supporting electronic components for over many years of experience supporting services.

Finally, took AT89S52 as the core, Designed contains the integration voltage-stabilizer circuit, the clock electric circuit, repositions the electric circuit, the liquid crystal display and the control circuit, ISP in-system programmable devices, the RS232 serial communication electric circuit in the system, the switching circuit, LED display circuit chip and the ISD2590 pronunciation chip recording/broadcast electric circuit and so on nine kind of periphery electric circuits, and compiles for the integrity schematic diagram.

最后，以AT89S52为核心，设计出包含集成稳压电路、时钟电路、复位电路、液晶显示与控制电路、ISP在系统可编程器、RS232串行通信电路、开关电路、发光二极管显示电路和ISD2560语音芯片的录音/播放电路等九种外围电路，并汇总为完整的原理图。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
