自营店增加查看缴款记录功能，可以查看门店缴款。 记录数据，门店只能查看自己的缴款记录。 使用同价调拨和变价调拨可以产生相应的GSP报表，即做完同价调拨和变价调拨，可以到对应报表中调用同价调拨单和同价调拨单生成GSP报表。 增加“盘点数量为零商品显示”功能，并增加对盘点时有改动商品的颜色标注，便于对有盘点改动商品的进行跟踪，并且可以在盘点过程中添加电脑中没有的库存商品（自动盘营盘亏中）。 库存盘点时增加“产地”、“备注”和“生产厂家”字段（自动盘盈盘亏）。-payment record increase View function can check stores contributions. Records data, stores can only check their payment record. Using the same price allocation and price changes can have a corresponding allocation of the GSP statements, the same price that is done allocation and price variable allocation, statements corresponding to the call to allocate the same price and with the price of single-generation GPS allocation statements. Increase the "zero inventory quantity of goods shows that the" function, and increase the inventory of goods has changed the color tagging, facilitate inventory changes to a commodity tracking, and inventory in the process of adding a computer without the stock (automatic disk business inventory

基于可编程跨导运算放大器POTA低通有源滤波器设计。该文给出了基于可编程跨导运算放大器(POTA)的有源滤波器设计方法，能在一定范围内实现跨导值程控调节, 提高调节精度和准确度。并且利用Jacobi 法求解相似对角形矩阵，避免解高次方程的难题。所设计的有源滤波电路不易受分布电容的影响，稳定性好、灵敏度低。本文给出了设计实例，显示了该方法的优点。-Based on programmable transconductance operational amplifier POTA low-pass active filter design. In this paper, based on the programmable transconductance amplifier (POTA) of the active filter design method that can realize in a certain range transconductance value of program-controlled adjustment, improve precision and accuracy regulation. Jacobi method and use a similar matrix of angular, high-equation solution to avoid problems. Designed active filter circuit less susceptible to the effects of distributed capacitance, good stability, low sensitivity. In this paper, design examples, showing the advantages of the method.
