一九八○年英国石墨输入总量为18,150吨,一九七九年为14,584吨,货源分布基本无变化。输入量增加是由于从马达加斯加输入量增加的缘故,输入量由一九七九年的3,122吨上升到传统的水平(5,946吨)。从中国的输入也稍高(2,339吨)。 In 1980, the total graphite input in the UK was 18,150 tons, and in 1979 it was 14,584 tons, and the supply distribution remained basically unchanged. The increase in imports was due to the increase in input from Madagascar, which increased from 3,122 tons in 1979 to the conventional level (5,946 tons). Imports from China are also slightly higher (2,339 tons).
