- Conclusion: CR films for diagnosing should be taken with minimum appropriate exposal dose in order to reduce the radiation quantity exposed to patients. 结论:找出或者利用最小的适宜曝光量,取得符合诊断要求的CR片,减少对患者的辐射剂量。
- The single-crystalline Cr films with the body-centered-cubic (bcc) structure are obtained, with the epitaxial relationship of (0 0 1)[0 0 l]||Cr(0 0 1)[001] GaAs and (001)[100]Cr(001)[100]GaAs . 当生长温度低于70℃的时候,Cr以bcc(211) 面平行外延在GaAs(001) 面上,当生长温度超过130℃的时候,Cr以bcc(001) 面平行外延在GaAs(001) 面上。
