qw

A new CASIC MANPADS weapon, the QW-19, was also shown.

CASIC的新MANPAD武器QW - 19也进行了展示。

The treatment group (145 cases) was treated by oral use of QW;

治疗组145例，口服清银丸治疗；

Men are all alike in their promises. It is only in their deeds that they differ. qw.

人们的承诺不相上下，只有行动才能显出差异。

The two wavelengths correspond to E1-HH1 and E2-HH2transitions in the QW respectively.

这两个激射波长分别对应于量子阱中E1-HH1和E2-HH2的跃迁。

To enhance the tunable photonic delay of a single QW SOA, we explore a serial cascade of multiple amplifiers.

为了提高单个量子阱半导体光放大器的可调光子延迟，我们进一步探讨了多个光放大器的串行级联。
