解释：
Note: The italics cells represent the comparatively stronger measure, where an analyst could expect to see a strengthening currency based on the factor being independently reviewed
解析：斜体的单元格代表的是相对较强的币种，分析师可以根据独立评估的因素预计货币会走强。
预期通胀越低的货币越强势
短期利率越高的货币越强势
经济增长越快随的货币越强势
越开放，越能保证外资前来投资的货币越强势
贸易顺差的货币更强势
如何理解贸易顺差，货币强势。老师能否解释一下这其中的逻辑。
这种顺差是否持续不是要看竞争力和可持续吗，说贸易顺差国家不愿意有那么高的saving rate。
