reduction in area meaning in Chinese
断面减少
面积缩减
Examples
- It is put forward that human activities disturbance has lead to the hydrographic and water resources environment changes directly , continuing reduction in area and loss in ecological function of wetland
指出人类活动的干扰直接导致沼泽湿地水文水资源环境的变化，湿地面积不断的减少，使湿地生态功能不断下降。 - 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
在第类脆性温度区内，不含sn钢的断面收缩率大于含sn钢的断面收缩率，即不含sn钢的热塑性要比含sn钢的热塑性好。 - Based on the hot tensile test results , there exists a cooling rate at which a minimum reduction in area occurs and the hot ductility of the sn - doped steel is worse than that of the sn - undoped steel . when the cooling rate is lower or higher than 10 / s , the hot ductility is increased
连续冷却到750 800范围内拉伸时，存在一个冷却速率( 10 s ) ，以这个冷却速率进行冷却，试样的断面收缩率最小，热塑性最差；当冷却速率大于或者小于这个冷却速率时，试样的断面收缩率均会增大，热塑性增强。 - The mechanical parameters at high temperatures - reduction in area ( ra % ) and tensile strength ( o b ) are measured by means of gleeble - 2000 thermal simulating machine . fracture surfaces are analyzed by scanning electron microscopy and optical microscopy . the segregation of sn is also examined by auger electron spectroscopy
通过测定试验钢种的高温力学参数(断面收缩率ra和抗拉强度_ b ) ，观察金相显微组织，分析扫描断口形貌，测试第二相析出物和俄歇能谱试验等方法，研究了残留元素sn及冷却速率对高温力学性能的影响。
