for the power demand of users, the power system scale is rising, so does single transformer capacity 为了满足电力需求,电力系统的规模日益扩大、变压器的单机容量也随着增大。
but with the system scale enlarging, its efficiency gradually declines and some problems such as sparsity, scalability and early rater will appear 但随着系统规模的扩大,它的效能会逐渐降低,暴露出矩阵稀疏性、扩展性和早期级别等问题。
but, when the system scale ( such as the number of customers or the types of products ) is very large, collaborative filtering faces great challenges 但是,当系统规模(用户数量、产品种类)很大时,推荐系统中的协同过滤技术面临着严峻的挑战。
especially in the part of logic control, adopt the newest digital system programmable logic device, simplify system design, reduce system scale and improve system reliability 尤其在逻辑控制部分,采用了最新一代数字系统可编程逻辑器件,大大的简化了系统设计,缩小了系统规模,提高了系统可靠性。
there are lots of conditions fit for using gprs : ( 1 ) traditional system ca n't be used or has difficulty to implement; ( 2 ) the system scale is large and has a 采用gprs无线传输在以下一些方面有应用意义:(1)在不能使用传统总线方式或使用有线方式布线困难很大的地方;(2)测控系统规模大、测控对象分布范围广的场合。
