例句與造句

1. the conclusion showed that the oxygen always made film's resistivity increase . the surface sheet resistance decreases with increasing dc power of zn target, zao thin films show minimum resistivity at the power of 100w; the conductivity get worse with further increase in dc power
   實驗證明氧氣的存在，會使得薄膜導(dǎo)電性降低；而隨著濺射功率的增加，薄膜的導(dǎo)電性變好，但當(dāng)功率超過100w后，薄膜的導(dǎo)電性反而變差。
2. It's difficult to find surface sheet in a sentence. 用surface sheet造句挺難的
