1 前言 长期以来,在我国港口的装卸作业中,煤炭、矿砂、粮食等大宗散货的计量,一直是采用看水尺的方法,计量准确度极低,存在着严重的亏吨现象。仅以煤炭为例,我国港口的煤炭吞吐量每年约2亿吨,其中出口5000万吨左右,港口煤炭装卸损耗率为2.5％。如果能下降1个百分点,那么每年可减少
1 Foreword For a long time, the loading and unloading operations in our ports have been the measurement method of large bulk cargo such as coal, ore, grain and so on. It has always been a method of measuring the water gauge. The measurement accuracy is very low and there is a serious loss of tonnage. Taking coal alone as an example, the annual coal throughput of China’s ports is about 200 million tons, of which about 50 million tons are exported and the port loading and unloading loss rate is 2.5%. If you can drop 1 percentage point, then every year can be reduced
