本文从国外资料刊载的流量仪表销售金额,考察国外流量仪表生产增长的速度和流量仪表不同品种的比例,并从部分品种的销售金额估算出几种流量仪表的产量(台套数)。1.销售金额统计和预测表1是日本、西欧六国和美国流量仪表历史销售金额,年平均增长率和1988/1989年销售额的预测值。表中日本销售金额项内带括号的数值已作了工业产品物价指数的修正(以1980年为100％)。1983年日、西欧、美国流量仪表销售额的比为1:1.6:2.6(按当时汇率1美元=250日元计算)。资料中对预测销售
This article from the foreign data published in the flow meter sales amount, to investigate the growth rate of foreign flow meter production and flow meter different varieties of the ratio, and from the sales of some varieties of the estimated number of flow meter production (sets). 1. Sales Amount Statistics and Forecast Table 1 is the historical sales amount of flow meters, the average annual growth rate, and the sales forecast for 1988/1989 for Japan, Western Europe, and the United States. The bracketed values in the Japanese sales amount in the table have been corrected for the industrial product price index (in 1980 it is 100%). In 1983 Japan, Western Europe, and the United States, the flow meter sales ratio was 1:1.6:2.6 (calculated at the exchange rate of 1 US dollar = 250 yen). Data for forecast sales
