undoped region 解釋
無摻雜區
  • undoped : 無摻雜的
  • region : n. 1. 地方，地域，地帶；地區；行政區，管轄區，區；左近，鄰近；（大氣、海水等的）層，界，境。2. 【解剖學；動物學】（身體的）局部，部位。3. （學問等的）范圍，領域。4. 〈罕用語〉天空。
  1. In the third ductility region, the reduction in area of the sn - undoped steel is larger than that of the sn - doped steel. this means that the hot ductility of the sn - undoped steel is better than that of the sn - doped steel

    在第類脆性溫度區內，不含sn鋼的斷面收縮率大於含sn鋼的斷面收縮率，即不含sn鋼的熱塑性要比含sn鋼的熱塑性好。
  2. The temperature at which the ra % is 60 % is about ~ 850 for the sn - undoped steel and ~ 910 for the sn - doped steel. the width of the ductility region of the sn - doped steel is obviously larger than that of the sn - undoped steel

    不含sn鋼的塑性凹槽上限大約為850 ，含sn鋼的塑性凹槽上限大約為910 ，含sn鋼的塑性凹槽上限明顯大於不含sn鋼。
