Edge clearance : the smallest distance from any conductors or components to the edge of the pcb 邊安全間距:導線或元件到pcb邊的最小間距。
Also , many household appliances are not on the list , but these may contain parts or components that are regulated 并且?許多家用電器不在清單上?但這些有可能包含了法規(guī)中的零件或元件。
The lead wire for loudspeader coil is suitable for the lead wires of loudspeader coil , electronic equipment or apparatus and components 揚聲器音圈接線是用于揚聲器音圈和電子電器設備或元件的接線。
In the manufacture of semiconductor devices , a photographically reduced representation of a circuit or element as used to establish an etching pattern 在半導體器件制造中,以縮小的照相方式表示的電路或元件,用于建立刻蝕圖案。
An accidental condition that causes device , component or element to fail to perform in a required manner . the fault may be either physical or logical 使設備、部件或元件不能按所要求的方式運行的一種意外情況。故障可能是物理上的,也可能是邏輯上的。
Direct connect vias conduct so much heat away from the pin and into the plane that high temperature or long soldering time may be required to complete the joint - thermal damage could occur to both the board and the component from soldering or desoldering 在焊接時,直接連接的過孔會通過引腳把大量的熱傳導至內電層,因此完成焊接就需要很高的溫度或者延長焊接時間,這就會導致在焊接或拆焊時發(fā)生電路板或元件的損壞。
System diagnosis and componentsdiagnosis can query the fault cause or fault place according to the visible fault phenomenaand can query the solving methods according to the cause and the pla ce . expert systemdiagnosis adopts man - computer dialog piatform , producing method , fault tree analysis andforward chaining . the user of hydrauiic equipment can eliminate the malfunction by thediagnosis of the software according to the visible phenomena 其中系統(tǒng)診斷和元件診斷能夠根據(jù)所需診斷系統(tǒng)(或元件)的故障現(xiàn)象診斷出可能的故障原因或部位,再根據(jù)找到的部位查得故障的排除方法;專家系統(tǒng)診斷采用了人機交互式界面、產生式規(guī)則表示法、故障樹的診斷模型、深度優(yōu)先搜索法和正向推理策略。
Module design is to construct functional circuits . with synthesizalbe and reusable vhdl codes . system simulation is completed under stimulus with software maxplus ii , by connecting every module in form of " block " or " component " , after every module is simulated with correct result 功能仿真使用的是altera的maxplus ,首先對每個功能模塊進行仿真,通過后,把各模塊以block或元件調用component的形式組成一個整體,通過波形輸入,對西安理工大學碩士學位論文整個系統(tǒng)進行功能仿真。
