我想就过去10年原镁的生产和消费趋向作一介绍,并对1987年和1991年镁的需求进行预测。首先,将1985～1986年原镁的生产和消费概述如下。如表1和图1所示,1986年的产量比1985年减少10kt(4.3%),主要原因是北美的产量下降了12.2kt(8.5%),另一方面是由于拉丁美洲和西欧的产量上升缓慢。可以认为每个地区的生产和消费是平衡的。 I would like to give an introduction on the trend of the production and consumption of primary magnesium in the past 10 years and forecast the demand for magnesium in 1987 and 1991. First, the production and consumption of virgin magnesium from 1985 to 1986 are summarized as follows. As shown in Table 1 and Figure 1, the 1986 production was 10kt (4.3%) lower than in 1985, mainly due to a 12.2kt (8.5%) drop in North American production and partly due to increased production in Latin America and Western Europe slow. It can be argued that production and consumption in each region are balanced.
