Energy saving fluorescent tubes with electronic ballasts , compact tubes , and separately controlled lighting circuits for perimeter and interior zones are used for the lighting system 照明裝置采用了省電熒光管配電子鎮(zhèn)流器、慳電燈膽,并將周邊和內(nèi)部區(qū)域的照明裝置開(kāi)關(guān)控制分開(kāi)。
The difference between the method that the sum and the subtraction of two - arm currents are separately controlled and the method that two - arm currents are separately controlled is discussed , and the later method which is more simple and accurate is selected 比較了總電流與差電流單獨(dú)控制和兩臂電流單獨(dú)控制這兩種穩(wěn)流方案的異同,從工程角度選擇了一種較易實(shí)現(xiàn)和精度高的方案。
( 2 ) a fuzzy - neural network multiple - variable control algorithm has been brought forward . it separately controls the two loops at the side of the boiler and at the side of the turbine , eliminates or reduces the coupling of each loop by the single - layer neural network ( 2 )提出了一種基于rbf神經(jīng)網(wǎng)絡(luò)的模糊神經(jīng)網(wǎng)絡(luò)多變量控制算法,分別對(duì)鍋爐側(cè)和汽機(jī)側(cè)兩個(gè)回路進(jìn)行控制,并通過(guò)一個(gè)單層神經(jīng)網(wǎng)絡(luò)的協(xié)調(diào)級(jí)來(lái)消除和減小各回路的耦合影響。
The author ' s main contributions are outlined as following : first , the roles of hot electron and hole in dielectric breakdown of ultra - thin gate oxides have been quantitatively investigated by separately controlling the amounts of hot electron and hot hole injection using substrate hot hole ( shh ) injection method . the changes of threshold voltage have been discussed under different stress conditions 主要研究結(jié)果如下:首先,利用襯底熱空穴( shh )注入技術(shù)分別控制注入到超薄柵氧化層中的熱電子和空穴的數(shù)量,定量研究了熱電子和空穴注入對(duì)超薄柵氧化層擊穿的影響,討論了不同應(yīng)力條件下的閾值電壓變化。
It elaborates on the 3 - step start technique . i adopt the method which permits the bldc motor to automatically search the best time to change its operation stage from a separately controlled synchronous one to a self controlled one using the back emf as the commutation signal . this method prevents the stepping out and stopping problems in the changing procedure of the motor 闡述了電機(jī)的三段式起動(dòng)方法,在直流無(wú)刷電機(jī)由起動(dòng)階段外同步運(yùn)行切換到反電勢(shì)換向自同步運(yùn)行的過(guò)程中采用了自尋最優(yōu)點(diǎn)切換的方法,保證了電機(jī)在切換過(guò)程中不會(huì)發(fā)生失步和停轉(zhuǎn)現(xiàn)象。
