The idea is that every odor molecule that enters our nose has a specific shape that fits a specific receptor-like a key fits a lock-allowing us to detect, say, the acrid aroma of burnt coffee.
这个想法是，每一个进入我们的鼻子的气味分子都有一个特定的形状，相互吻合的特定受体——就像锁和钥匙一样——使我们能够感知，例如感知焦咖啡的刺鼻气味。
In particular, Lock - in thermography is more suitable to detect composite material structure.
特别地，锁相热成像更适合用来检测复合材料结构。
This new algorithm can detect and repair cycle slips after loss of lock within 3 seconds so as to avoid the effect of cycle slips on smooth pseudo distance of carrier phase.
检验证明该方法能够准确可靠地探测并修复失锁3秒以内的周跳，避免了周跳对载波相位平滑伪距的影响。
