In this task , we presented and designed a system that can classify and recognize circular and quadrate parts and the intension image of industrial parts is the object of the system , human - computer communication mode is adopted to identify the parts 在本課題中,主要進行了對圓形和方形零件分類識別系統的研究和設計,針對的對象是工業零件的強度圖像,采用人機對話方式來對零件進行識別。
Bile ducts of hilus hepatis , right or left lobe , medial segment and anterior right segment can be exposed and incised through hilus hepatis or quadrate lobe . all major intrahepatic bile ducts of the right lobe can be exposed and incised by an approach cutting through the liver parenchyma on its diaphragmatic surface 經肝門區或肝方葉可以顯露和切開肝門膽管、左右肝管和左內葉、右前葉膽管,經肝膈面切開肝實質進路,可以顯露和切開右肝內各葉段膽管。
This machine adopts the best advanced imported frequency conversion timing controlled technical drive . it adopts dlectrical brake setting , its deendability is lofty and cutting is exact . this machine is mostly used for many quadrate foam rubber once flatly slicing . it can be continuously cutout , and do not recede cutter , the production efficiency is better 70型采用當前最先進的進口變頻調速技術驅動,去除落后的抱閘剎車裝置,可靠性高,切割精確,本機主要用于多個方泡泡綿的一次性水平切片工作,連續切割,不用退刀,生產效率更高。
On the basis of analysis on the pairwise action of cement paste , nanometer silica fume and clay , the paper proposes the reinforcement mechanism of the cemented soil stabilized with nanometer silica fume . the reinforcement mechanism includes cementation action of cement hydrate , ionic exchange and quadrate reaction of clay particle , pozzolanic effect , filling effect and cementation action of nanometer silica fume 在研究水泥漿?納米硅粉、納米硅粉?粘性土、水泥漿?粘性土相互作用的基礎上,將納米硅粉水泥土的固化機理總結為:水泥水化物的膠結作用、粘土顆粒中的離子交換效應和“二次反應” 、納米硅粉的火山灰效應、納米硅粉的填充效應、納米硅粉的膠結作用。
The growth dynamics of tree basal area of form . taxus chinensis var . mairei population in different altitude were discussed using the liu - logistic model , and the results showed that the altutide of 790 meters is more suitable to the survive of form . toms chinensis var . mairei population than 990 meters . plot sampling was selected and dynamic analysis was used to study the height structure of taxus chinensis var . mairei population , and the quadrate picture of height structure and the curve of survival rate were drew 運用改進模型對南方紅豆杉種群在不同海拔梯度的種群優勢度增長進行了探討,表明海拔790m處的南方紅豆杉具有較大的環境容納量,但增長速度不快,海拔990m處的南方紅豆杉種群環境容納量不高,但具有較大的增長速度,這可能與群落的發育階段不同有關,兩地海拔均為南方紅豆杉適宜的生長海拔高度,相比而言,海拔790m的珍稀瀕危植物南方紅豆杉種群數量特征的研究高度更宜于南方紅豆杉種群的生長。

The student said " hello " to all of us when we met him . he was thin and his face was black , seems that he was undernourished . his father brushed the chairs with his sleeves immediately , asked us to sit down . his mother leaned the door with foolish smile all the time . it was even poorer of their family than our thought . the lime had started to come off as the wind and rain damage , the sunshine got through their house , shadow was remained on the sap of floor . two small rooms , a kitchen , a quadrate desk and some chairs here , there were not anything else ; the other one was bedroom , two beds were squeezed together . the bedding wasn ' t new any more and turned white , cotton was come out from the clothes . the only thing was what one old desk was cleaned well , it should be his book desk , there were some books on it 那位學生見我們來了,高興地向我們問好.他看上去瘦瘦的,臉色黝黑,一副嚴重營養不良的樣子.他的父親趕緊用袖子在長凳上擦拭了幾下,笨拙地端給我們坐.他的母親一直倚著門檻傻傻地笑.他的家比我想像的更窮.墻面上的石灰經不起風雨的侵蝕而紛紛脫落,陽光透過磚縫射進屋里來,在坑坑洼洼的地面上留下一個個斑駁的影子.兩間小屋,一間是灶間,除了一張方桌和幾張長板凳外,別無他物;另一間是臥室,兩張床擠在一起,被褥舊得發白,墊被連棉絮都露在外面.唯一整理的井井有條的是一張舊桌子,應該是他的書桌吧,上面整整齊齊放著幾本書
