Desktop system means that it is fit for office and has low cost , compact volume , light weight and also high speed , low noise in molding process 所謂桌面化,就是要求系統(tǒng)適合于辦公應(yīng)用,具有成本低、速度快、體積小、重量輕、噪音小等特點(diǎn)。
Switch mode power supply , with its compact volume , small weight , high efficiency and good line regulation , has been widely applied in most of electronic fields 開(kāi)關(guān)電源( switchmodepowersupply )由于具有體積小、重量輕、效率高、輸出穩(wěn)壓范圍寬等優(yōu)勢(shì),被應(yīng)用于各種電子、電器設(shè)備領(lǐng)域。
Comparing with conventional electromagnetic transformer , piezoelectric transformer has many advantages such as compact volume , high step - up ratio , non - flammability and none - electromagnetic pollution , which is an indispensable part in the electronic information system 壓電變壓器相對(duì)于傳統(tǒng)的電磁變壓器具有體積小、重量輕、升壓比高、不易燃、無(wú)電磁污染等特點(diǎn),較好的解決了電磁壓電變壓器體積大、電磁污染嚴(yán)重等缺陷,是電子信息系統(tǒng)中不可或缺的重要部件。
The three - ring gear reducer ( trgr ) , invented by a chinese engineer in 1985 , is a novel type of planetary transmission device with few tooth difference , which has numerous advantages over traditional reducers , such as large transmission ratio , high loading capacity , compact volume , low manufacturing cost and wide adaptability etc , and it has been widely used in many fields 三環(huán)減速器是中國(guó)科技人員發(fā)明的一種少齒差內(nèi)嚙合行星齒輪傳動(dòng)裝置,其傳動(dòng)原理新穎,具有傳動(dòng)比大、承載能力強(qiáng)、結(jié)構(gòu)緊湊、成本低廉和適應(yīng)性廣等諸多優(yōu)點(diǎn),在很多領(lǐng)域已得到廣泛應(yīng)用。
At last , relation between optical efficiency and etendue value is analyze . zemax and lighttools are used in the design of fly - eye lens array illumination system , which has many advantages including compact volume , high efficiency and uniformity . now it has been applied in commercial 0 . 9 inch tft - lcd panel projector 在深入分析設(shè)計(jì)原理的基礎(chǔ)上,使用zemax 、 lighttools等軟件實(shí)現(xiàn)了結(jié)構(gòu)緊湊、高光能利用率、高均勻性的偏心的蠅眼透鏡陣列設(shè)計(jì),在0 . 9英寸tft - lcd面板的投影儀上已經(jīng)被商業(yè)應(yīng)用,達(dá)到了廠家的技術(shù)指標(biāo)要求。
The computers which are embedded into some sets are called embedded computer . so , it ' s most visiable feature is the so small and compact volume . the embedded computer provides kinds of function interfaces for users , administrates the whole system ' s inputs and outputs , and contral set ' s calculate ability . so that , sets with embedded computer have more excellence . profibus - dp fieldbus is a kind of communications standard and technique developed for the industrial field condition . to link the field fixings that require controlling and watching to the field controller whose core is embedded oprating system , and realize field controlling is its function . for field fixings that may communicate each other , they can communicate each other independently by means of profibus - dp , then the work ' s security and efficiency are increased . speaking vividly , profibus - dp fieldbus system is a small dcs control system . in the whole , profibus - dp fieldbus puts parts of the dcs control system ' s function , that will be realized by the field controller , down to the industrial field Profibus - dp現(xiàn)場(chǎng)總線是為適應(yīng)工業(yè)現(xiàn)場(chǎng)的條件,開(kāi)發(fā)的一種通信標(biāo)準(zhǔn)和技術(shù)。它的作用就是把現(xiàn)場(chǎng)需要監(jiān)測(cè)和控制的設(shè)備按此標(biāo)準(zhǔn)連接到使用嵌入式操作系統(tǒng)的現(xiàn)場(chǎng)控制平臺(tái),實(shí)現(xiàn)設(shè)備的就地控制。對(duì)某些有相互通信要求的現(xiàn)場(chǎng)設(shè)備,就可以直接通過(guò)profibus - dp現(xiàn)場(chǎng)總線實(shí)現(xiàn)獨(dú)立相互通信,而不必通過(guò)使用嵌入式操作系統(tǒng)的現(xiàn)場(chǎng)控制平臺(tái),提高了工作的可靠性和工作效率。
