excel的使用教程，包含简单的excel的编程，以及很多公式算法的使用方法，是学习excel应用的很好的资料(the use of excel tutorial, including a simple excel programming, and many algorithms use the formula is applied to learn good information excel)

本软件是成型的软件，但我没有地方放，所以放在这里，请见谅，主要用于限制孩子浏览不健康的网页，在软件中只有家长允许的网页才能浏览。也请各位高手帮我测试传播一下，-the software is molding software, but I have no place to, so here and I do apologize, mainly used to restrict children"s web browser unhealthy, the software allows only parents can browse the website. Please help me to master communication about testing, thank you

说明：  This article introduces two new configurations for precision current sources and current mirrors. Both circuits use n-p-n bipolar devices, but one provides a current source while the other provides a current sink. This permits the use of current sources in IC designs implemented with processes that do not allow p-n-p devices. Analog building blocks such as voltage-to-current converters, active loads, and sink and source current mirrors can be constructed from the new circuits using only n-p-n devices. Furthermore, because these circuits achieve the required precision without the use of high-gain amplifiers, the bandwidths of the circuits are large compared to conventional configurations. The source currents are dependent on a single reference voltage and exhibit good temperature sensivitity
