The PNW export program has been beset by weakened wheat exports and slower corn exports as compared to last year.

困扰太平洋西北沿岸的问题是，与去年相比，小麦的出口形势不佳，玉米的出口进度放慢。

The effects of NiW contents on the crystallographic phase, microstructure, electromechanical properties and temperature stability of PMS-PNW-PZT materials were studied.

PZT体系的相组成、微观结构、机电性能、温度稳定性的影响。

Meanwhile, the spread between the Gulf and Pacific Northwest (PNW) is widening and nearly provides a shipper no clear advantage whether to ship from the PNW or the Gulf.

另外，墨西哥湾和太平洋西北岸之间的运价差正在拉大，使承运商无论从太平洋西北岸起运还是从墨西哥湾沿岸起运，均不能享受明显优势。
