求翻译：在1983到1987年间，失业率都在百分之十之上。1987年后，失业率开始减少，到1990年时已不足百分之6，之后又开始回升，并在1993年达到近百分之十的时候，开始稳定的下降。是什么意思？

In the years 1983-1987, the unemployment rate is above the 10%. After 1987, the unemployment rate began to reduce, by 1990 had less than 6 per cent and later began to rebound, and in 1993 to nearly 10% of the time, began to steady decline.
