arc trace
解釋
電弧痕跡-
As a new type gear transmission, double circular arc profile bevel gearing carries out its transmission by means of meshing between convex - concave tooth profile in both of the direction of tooth trace and the direction of tooth depth, so it has advantage of high load capacity, long service life, easy forming hydrodynamic oil film between teeth as well as high quality of running - in etc. therefore, more attention has been paid to its application and research in recent years
作為一種新型齒輪傳動方式，雙圓弧弧齒錐齒輪傳動不論在齒線方向、還是在齒高方向，均為凸、凹齒廓相嚙合，因而它比一般的弧齒錐齒輪傳動的承載能力高，使用壽命長；並且在嚙合過程中兩齒面間容易形成潤滑油膜，具有良好的跑合性能，所以對它的應用和研究日益受到人們的重視。 -
In the solid model building program, based on the cutting tooth theory of double circular arc profile spiral bevel gear and autocad software, a series of computer simulations about solid model building and cutting tooth process of the gear were curried out. the cutter ' s tooth shape, the processed gear blank shape and its conjugated tooth profile shape as well as visual movement relationship between generating gear and processed gear blank etc. were obtained. the relative position of cutter and processed gear as well as the movement trace and rule in the cutting process can be showed dynamically on screen
在實體建模程序中，以雙圓弧弧齒錐齒輪的加工原理為基礎，藉助繪圖軟體autocad ，模擬了雙圓弧弧齒錐齒輪銑刀盤刀齒形狀、輪齒毛坯形狀等，進而根據產形輪與被加工齒坯之間的共軛嚙合關系，進行了雙圓弧弧齒錐齒輪的實體建模及加工過程模擬，在屏幕上動態顯示刀具及被加工齒輪的相對位置及其加工時的運動軌跡和規律。 -
Based on the geological, stratigraphic and geochemical characteristics of the ophiolitic melange, island - arc and rift volcanic rocks from the jinshajiang zone, an archipelagic tectonic model with multi - rift and multi - subduction is proposed to explain the evolution of jinshajiang paleo - tethys. the ophiolitic melanges of the jinshajiang zone are mainly outcropped at baimangxueshan, tongduo, gongka, dongzhulin and jiyidu in the deqin county. the geochemistry of major and trace elements of the jinshajiang ophiolite shows its geochemical characteristics are similar to those of the more and island - arc volcanic rocks, but different from those of the typical n - mopjb
金沙江蛇綠混雜巖主要分佈在德欽縣的白茫雪山、通多、共卡、東竹林和吉義獨地區，主量和微量元素地球化學特徵研究表明，金沙江蛇綠巖不具有典型n - morb的地球化學特徵，而具有介於morb和島弧之間的地球化學特徵，暗示它並非形成於寬闊的大洋環境，不是古特提斯在滇西北地區的主縫合帶，可能是古特提斯多島洋體系中的一個弧后盆地。 -
The mafic dykes are characterized by arc - like trace elements, high initial 87sr / 86sr ratios and low end ( t ) values, and show some familiarities with the emii - mantle source
海南島基性巖脈具有與「島弧」特徵相似的微量元素組成特徵以及高sr 、低nd的同位素特徵，表明其源自具有em特徵的富集地幔。 -
A kind of heuristic information based on the dannenbring approach is introduced in the procedure of solution construction. the experiment shows that the stagnation step out mechanism and the pheromone trail limit mechanism can help ants stepping out of stagnation and the heuristic information is very effective, in addition, the eligibility trace mechanism in ant - q ( ) algorithm can greatly improve the performance of algorithm based on solution construction graph in arc mode
模擬試驗表明，信息素的結點模式總體優于孤模式；啟發式信息能較大改進演算法性能； acostag演算法的信息素蹤跡更新過程中的停滯狀態脫離機制以及信息素蹤跡限制機制能幫助螞蟻跳出局部最優解；此外antqo ）演算法的資格跡機制能大大改進採用弧模式解構造圖的蟻群演算法性能。
