After the usual waiting period Ms Huang received her PVA and took her medical. She couldn't believe it when her visa arrived shortly afterwards.
在通常的短期的等待之后，黄女士收到了她的预签，并通过身体检查。当她收到签证时，她简直不能相信签证能如此快的来到。
An algorithm for resolution of overlapping gas chromatographic-mass spectrometric(GC-MS) signal using continuous wavelet transform-pure variable approach(CWT-PVA) was proposed.
提出了连续小波变换-纯变量法（CWT-PVA）解析气相色谱-质谱（GC-MS）重叠信号的新方法。
The burst release of wafer protected by blank MS was restrained, however, no obvious restrain effect was observed for wafer protected by PVA for its quickly falling off.
膜片表面空球和PVA涂层两种保护形式中，空球保护可明显减弱膜片的初期突释，而PVA涂层保护由于其很快脱落，对膜片的突释抑制不明显。
