So susceptibility to cold symptoms is not a sign of a weakened immune system, but quite the opposite.
因此，易受感冒症状的影响并不是免疫系统虚弱的一种迹象，情况刚好相反。
However, there has previously been little direct evidence that poor sleep increases susceptibility to the common cold.
然而，没有直接证据表明睡眠质量不高会增加患普通感冒的几率。
What mechanisms might link sleep to cold susceptibility?
什么机理导致了睡眠和患感冒的几率？
The sample magnetic susceptibility curve as a climate and environment index can show the research area's change and reflect the process of dry and cold to warm and humid.
样品频率磁化率曲线作为一种气候环境变化的代用指标也可以说明研究区域气候环境的变化，反映了一种干冷向暖湿变化的过程。
A new low alloying steel with low susceptibility to weld cold cracking has been developed for large heat input welding in pressure vessel engineering.
试验结果表明，该钢具有焊接冷裂纹倾向低、可用大线能量焊接、焊后不宜进行消氢处理等特点，可用作高强度大焊接线能量用钢。
