for the power demand of users, the power system scale is rising, so does single transformer capacity 為了滿足電力需求,電力系統(tǒng)的規(guī)模日益擴(kuò)大、變壓器的單機(jī)容量也隨著增大。
but with the system scale enlarging, its efficiency gradually declines and some problems such as sparsity, scalability and early rater will appear 但隨著系統(tǒng)規(guī)模的擴(kuò)大,它的效能會(huì)逐漸降低,暴露出矩陣稀疏性、擴(kuò)展性和早期級(jí)別等問(wèn)題。
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,當(dāng)系統(tǒng)規(guī)模(用戶數(shù)量、產(chǎn)品種類)很大時(shí),推薦系統(tǒng)中的協(xié)同過(guò)濾技術(shù)面臨著嚴(yán)峻的挑戰(zhàn)。
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 尤其在邏輯控制部分,采用了最新一代數(shù)字系統(tǒng)可編程邏輯器件,大大的簡(jiǎn)化了系統(tǒng)設(shè)計(jì),縮小了系統(tǒng)規(guī)模,提高了系統(tǒng)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無(wú)線傳輸在以下一些方面有應(yīng)用意義:(1)在不能使用傳統(tǒng)總線方式或使用有線方式布線困難很大的地方;(2)測(cè)控系統(tǒng)規(guī)模大、測(cè)控對(duì)象分布范圍廣的場(chǎng)合。
