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

恒流驱动和提 高LED的光学效率是LED 应用设计的两个关键问题，本文首先介绍大功率LED的应用及其恒流驱动方案的选择指南，然后以美国国家半导体(NS)的产品为例，重点讨论如何巧妙应用 LED恒流驱动电路的采样电阻提高大功率LED的效率，并给出大功率LED驱动器设计与散热设计的注意事项。-LED constant current drive and to improve the optical efficiency of LED application design of two key issues, this paper describes the application of high-power LED constant current driver and the choice of the program guide, and then the United States National Semiconductor (NS) products, for example, focus on how skillful application of LED constant current driver circuit of the sampling resistor to improve the efficiency of high-power LED, and gives high-power LED driver design and thermal design considerations.
