世界激光商品的销售金额从前年的5.22亿美元上升到1987年的5.7亿美元,增长率9%,虽较1986年公布的6%有所增加,但仍达不到以往20%的年增长率。看来,激光发展初期两位数的年增长率再也不会回来了,因为1987年虽然有些部门增长较高,但是世界激光市场的生意却比过去任何时候都难做得多。首先是材料加工工业,它占激光总市场的27%,在1980年下降5%以后,再也没有高涨。1.29亿美元的销售金额仍旧萧条,留下一
The sales volume of laser products in the world rose from 522 million U.S. dollars in the previous year to 570 million U.S. dollars in 1987, with a growth rate of 9%. Although it increased compared with 6% announced in 1986, it still failed to achieve the annual growth rate of 20% in the past. . It seems that the double-digit annual growth rate in the early days of laser development will never come back, because in 1987 although some sectors were growing at a higher rate, the world laser market is more difficult to do than ever before. The first was the material processing industry, which accounted for 27% of the total laser market. After a decline of 5% in 1980, it did not rise again. The $129 million sales amount is still sluggish, leaving behind
