flat scanning
解釋
平面掃描-
The main computer is programmed under windows, while the assistant computer is programmed under dos. the last, based on the idea of module - structure, the software of the testing system are designed, thus this software system is compatible and transplantable to design again. the experiment of measuring principle is taken : take the xy flat of lathe as the parallel - pole device and adjust the angle of sensor, the rotating - probe can test the felloe mould in scanning way
藉助虛擬儀器的思想，對測控系統進行了設計：採用光柵尺、光電編碼器測量可動部件的運動量，解析度高、誤差小；採用細分驅動的步進電機裝置，控制性能好；系統實施環境溫度的檢測、補償，提高了檢測精度；基於兩級微機組建測控系統：主機為人機界面，採用windows編程，從機用dos編程，實時性好；軟體設計採用兼容性和移植性好的模塊式結構，便於二次開發。 -
In the present dissertation, friction - induced noises emitted by a flat specimen rubbing against another flat specimen or a ball specimen under reciprocating sliding are studied. the detailed observation of the scars is conducted by means of a scanning electrical microscope ( sem ), laser scanning microscope ( lsm ), optical microscope and profilometer. the dynamic state variables are analyzed in detail using the discrete wavelet transform
使用電子掃描顯微鏡（ sem ） 、激光掃描顯微鏡（ lsm ） 、光學顯微鏡和表面輪廓測量儀等設備對摩擦噪聲發生的區域進行了詳細的觀察和分析，運用小波變換技術對摩擦噪聲狀態下的動力學變量進行了深層次的研究，應用matlab simulink語言對摩擦系統進行了振動動力學模擬，系統地研究了摩擦噪聲的形成機理。 -
The shadow mask is the critical component of the colour picture tube and the important component for the choice of colour, its function concentrates on the limitation of electronics bound diameter and the screening direction, the electronics bound which is sent by the electronics gun goes scanning, during the scanning process, we should guarantee every bound gathering into the small holes situated on the screen, then these bounds will point to the regularized position through the small holes on the flat mask, and then three basic colours will be produced, at the same time, those useless electronics will be blocked by the mask board
平板蔭罩是彩色顯像管的關鍵部件之一，是一個重要選色元件，其作用是限制電子束直徑和上屏方向，由電子槍發射的電子束在偏轉磁場的作用下進行掃描，掃描過程中必須使每個電子束只能射中熒光屏上的為該束指定的那些小孔上會聚，並通過蔭罩上諸多的小孔分別打到各自對應的熒光質點上，發出三種基色（紅，綠，藍） ，而無用的電子則被蔭罩板截獲。 -
Targets made of ship - building steel, which is concerned, were penetrated by conical and flat - ended projectiles. the damage and failure behaviors of targets have been studied systematically by micro - hardness, metallography and scanning electron micrography. the results show that the ductile hole failures and back - surface petal failures are achieved when targets penetrated by the conical projectiles
本文以某船用鋼為研究對象，運用彈板侵徹試驗及顯微硬度、金相顯微鏡和sem等分析測試手段，研究了靶材在侵徹過程的物理變化和損傷規律，從而對尖頭彈和鈍頭彈侵徹船體鋼的物理過程有了較全面的了解。 -
Using the 2 - dimension numerical control machining flat and dual galvanometer scanning system is to enlarge marking scope and to make up the shortcoming of slow marking velocity of immovable mode and deficiency of small marking scope of movable mode. this method is fit for the situation of larger scope, which improves produce efficiency
本系統選用二維數控加工平臺結合雙振鏡掃描系統，擴大打標范圍，彌補了定光式打標速度慢的缺點和動光式打標范圍小的不足，適用於打標圖形較大的場合，提高生產效率。
