A new wave of Chinese migration is afoot, fuelled by ever-younger students for whom English is not a piece of knowledge to be learnt but a living language able to unlock the intricacies of the wider world.

新一轮的华人移民潮正在进行时，而其背后的推动者则是一群越来越年轻的莘莘学子。英语对这一代人来说不再只是一门知识，而是解开大千世界纷繁奥秘的一门鲜活的语言。

Fluorescent ternary diagram and synchronous fluorescence spectrum can properly indicate the direction of the micro migration: from deep strata to surface, R 320 increases,λ 360 nm decreases and every wave band possesses positive gradient with the exception of λ 430 nm

荧光光谱三元图和同步荧光图谱能较好地指示微运移的方向：自深层到地表，λ320nm增加，λ360nm减小；除λ430nm外，各波段均具正向梯度
