sun radius 中文意思是什麼
sun radius
解釋
輝球半徑-
Michell computed that a body 500 times the radius of the sun and of the same density would have at its surface an escape velocity equal to the speed of light, and therefore would be invisible
米切爾計算一個500倍太陽半徑而且具有相同密度的物體就會具有它的表面逃逸速度等於光速，而因此不可見。 -

電纜導體的長期允許工作溫度65 ，電纜的最小彎曲半徑為電纜直徑的6倍。黃色護套電纜不得在日光下長期暴露。 -
The allowed working temperatureof the core is 65 its smallest bending radius issixtimes the size of cable diameter. the yellow sheath calbe shoulo not be exposed in the sun for long
線芯長期允許工作溫度65 ，電纜的最小彎曲半徑為電纜直徑的6倍。黃色護套電纜不得在日光下長期暴露。 -
The radius of the sun is about 700, 000 km, approximately 110 times the radius of the earth. its mass is about 2x10
太陽的半徑大約有700 ， 000公里是地球的110倍，質量則大約有2x10 -
The research results include the follows : present some rules for selecting measuring method according to the characteristics of product, study some problems in data preprocessing such as noise removing, probe radius compensation, edge data extracting, sun - regions merging, and local data mending or re - sampling etc. to ensure the part cad models being built and assembled accurately at dimension and shape in re modeling application, three kinds of model modifying techniques are presented such as model - based modifying, drawing - based modifying and physical model - based modifying
這些問題包括：根據產品表面形狀及建模方法，提出了一些選擇測量方法的原則；研究了消除測量數據噪聲信號、 cmm測頭半徑補償、測量數據邊界處理、測量數據塊拼合、數據補缺與補測等測量數據預處理問題。為了解決復雜外形產品re建模經常遇到的零件cad模型配合問題與尺寸精度、形狀精度問題，作者研究了基於cad模型的修正、基於零件圖樣的修正、基於物理模型的修正等三種模型修正技術。
