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 所谓桌面化,就是要求系统适合于办公应用,具有成本低、速度快、体积小、重量轻、噪音小等特点。
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 开关电源( switchmodepowersupply )由于具有体积小、重量轻、效率高、输出稳压范围宽等优势,被应用于各种电子、电器设备领域。
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 压电变压器相对于传统的电磁变压器具有体积小、重量轻、升压比高、不易燃、无电磁污染等特点,较好的解决了电磁压电变压器体积大、电磁污染严重等缺陷,是电子信息系统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 三环减速器是中国科技人员发明的一种少齿差内啮合行星齿轮传动装置,其传动原理新颖,具有传动比大、承载能力强、结构紧凑、成本低廉和适应性广等诸多优点,在很多领域已得到广泛应用。
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 在深入分析设计原理的基础上,使用zemax 、 lighttools等软件实现了结构紧凑、高光能利用率、高均匀性的偏心的蝇眼透镜阵列设计,在0 . 9英寸tft - lcd面板的投影仪上已经被商业应用,达到了厂家的技术指标要求。
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现场总线是为适应工业现场的条件,开发的一种通信标准和技术。它的作用就是把现场需要监测和控制的设备按此标准连接到使用嵌入式操作系统的现场控制平台,实现设备的就地控制。对某些有相互通信要求的现场设备,就可以直接通过profibus - dp现场总线实现独立相互通信,而不必通过使用嵌入式操作系统的现场控制平台,提高了工作的可靠性和工作效率。
