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,就是要求系統適合于辦公應用,具有成本低、速度快、體積小、重量輕、噪音小等特點。
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 開關電源( switchmodepowersupply )由于具有體積小、重量輕、效率高、輸出穩壓范圍寬等優勢,被應用于各種電子、電器設備領域。
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 壓電變壓器相對于傳統的電磁變壓器具有體積小、重量輕、升壓比高、不易燃、無電磁污染等特點,較好的解決了電磁壓電變壓器體積大、電磁污染嚴重等缺陷,是電子信息系統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 三環減速器是中國科技人員發明的一種少齒差內嚙合行星齒輪傳動裝置,其傳動原理新穎,具有傳動比大、承載能力強、結構緊湊、成本低廉和適應性廣等諸多優點,在很多領域已得到廣泛應用。
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 在深入分析設計原理的基礎上,使用zemax 、 lighttools等軟件實現了結構緊湊、高光能利用率、高均勻性的偏心的蠅眼透鏡陣列設計,在0 . 9英寸tft - lcd面板的投影儀上已經被商業應用,達到了廠家的技術指標要求。
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現場總線是為適應工業現場的條件,開發的一種通信標準和技術。它的作用就是把現場需要監測和控制的設備按此標準連接到使用嵌入式操作系統的現場控制平臺,實現設備的就地控制。對某些有相互通信要求的現場設備,就可以直接通過profibus - dp現場總線實現獨立相互通信,而不必通過使用嵌入式操作系統的現場控制平臺,提高了工作的可靠性和工作效率。
