1.
Using the daily minimum temperature data of 100 stations in Northwest China in 1960-2004,the thresholds of daily extreme low temperature are determined for different stations,diagnosis of the frequencies of temporal and spatial distributions of annual extreme low temperature events is made for the recent 45 a,and their response to regional warming in Northwest China is analyzed.
利用中国西北五省(区)1960-2004年100个台站逐日最低温度资料,通过百分位法定义了不同台站的逐日极端低温阈值,对近45 a来西北地区逐年极端低温事件发生频次进行了时空诊断,并分析其同西北区域性增暖的响应。

补充资料：“质子-电子偶极-偶极”质子弛豫增强
“质子-电子偶极-偶极”质子弛豫增强
物理学术语。原子核外层中不成对的电子质量小，但磁动性很强，可使局部磁场波动增强，促使氢质子弛豫加快，从而使T1和T2缩短，这种效应即为PEDDPRE。过渡元素和镧系元素大部分在d和f轨道有多个不成对电子，所以其离子往往具有PEDDPRE，可用来作顺磁性对比剂，如钆(Gd)。Gd在外层有7个不成对电子，具有很强的顺磁性。
