The natural scale of a chart is the ratio of a length measured on the chart to a corresponding length measured on the surface of the Earth and is expressed as a fraction. 海图的基准比例尺是图上一个单位长度与其对应的球面上长度的之比,用分数表示。
Increase the image noise, and1 to4 layers of wavelet decomposition denoising, signal to noise ratio is given chart. 对图像加噪,并进行小波1到4层分解去噪,给出信噪比走势图。
For more than a century, the cyclical price/ earnings ratio where share prices are compared with average earnings over the last 10 years rather than merely the latest year has been a reliable indicator of market cycles ( see chart). 一个多世纪以来,周期市盈率拿股价与过去10年的平均收益相比,而非仅与上年相比一直是衡量市场周期的可靠指标(见图表)。
China leads the pack, with a rise of 70 percentage points in the ratio of corporate and household debt to GDP between 2007 and 2014 ( see chart). 中国在这方面一马当先,2007年至2014年间企业和家庭债务与GDP之比上升了70个百分点(见图表)。
Under these assumptions, the ratio of debt to GDP would stabilise at about 73 per cent ( see chart). 按照这种假定,债务对GDP的比例将会稳定在大约73%。
