All the doorways had rectangular frames ; they were in the front part in sets of three , facing each other 5所有的門框、都是厚木見方的、有窗戶三層、窗與窗相對。
In facsimile transmission , deviation from the rectangular frame due to a lack of synchronism between transmitting and receiving scanner 在傳真?zhèn)鬏斨?因發(fā)送和接收掃描器之間的不同步而產(chǎn)生的偏離矩形框的現(xiàn)象。
A piece of furniture for reclining and sleeping , typically consisting of a flat , rectangular frame and a mattress resting on springs 床一件為躺靠和睡覺用的家具,典型的由一個平的,矩形的柜架和放在彈簧上的墊子組成
The picture frames designed by master make a perfect match for her paintings . there is no comparison between master s and the ordinary rectangular frames 師父設(shè)計的框加上畫就相當(dāng)?shù)耐昝溃蚱匠?吹漠嫸际撬姆娇颍磶煾冈O(shè)計的框感覺真是差太多了!
Strong rectangular frame fixed by screws , an inset hole every 25cm to fix the slotting auger , guard board , bunches of cables and circuit diagram sidekicks , etc 堅固的用螺絲固定的長方框,每隔25毫米有一個嵌孔,用來固定槽溝、護板、電纜束及線路圖插袋等。
Firstly , the methods to restrain the effect of ship swing are studied for two - axes shipbome radar . two different methods based on ship rectangular frame and inertial frame are proposed separately according to consistence of radar base angle and beam angle 本文首先研究了艦載兩軸雷達系統(tǒng)抑制船搖的方案,對雷達天線轉(zhuǎn)角和波束轉(zhuǎn)角一致和不一致的情況,分別提出了基于甲板坐標(biāo)系穩(wěn)定和基于大地坐標(biāo)系穩(wěn)定的不同方法。
Considering the characters of 3 - axes coordinate system that is not included in ship rectangular frame or inertial frame , compensation conditions are deduced through studying the effects of ship - swing . the paper studies how to transfer line velocity and acceleration in the inertial frame to angular velocity and acceleration which correspond each axis , then gives the computer function scheme . servo control scheme which can overcome ship swing and realize moving - target accurate tracking is designed according to inconsistency of radar base angle and beam angle 針對三軸軸系既非甲板坐標(biāo)系又非大地坐標(biāo)系的特點,既研究了船搖對正交三軸雷達系統(tǒng)的影響,推導(dǎo)實現(xiàn)船搖不變性的補償條件,又研究了將目標(biāo)在大地坐標(biāo)系中的線速度和線加速度濾波值折算到各軸對應(yīng)的角速度和角加速度值的計算關(guān)系,并作出了計算機功能框圖。
