Draw your Bow into a deeper curve by using your right hand and arm to resist the backward push of your right foot.
以右手和右手臂的力量抵抗右脚向后的推力来加深你弓柄的曲度。
The negatively sloped portion of a supply curve like that in Figure 5.1(b) is frequently referred to as a "backward-bending" supply curve;
图5.1（b）中的供给曲线的负斜率部分就是通常所谓的“向后弯曲”的供给曲线；
It is found that in the backward voltage segment of the I-V curve the leakage current is larger because of deep-level-assistant tunneling;
结果表明，相对理想情形，特性曲线的反向偏压区漏电因深能级隧穿偏大；正向小偏压下因沿着位错汇聚金属产生漏电流；
