作者 熊家齐 《稀土信息》 2003年第5期6-12,共7页
在琳琅满目的稀土新材料系列中,发光材料无疑属一重大领域,不仅应用的稀土总量大,其所需单一稀土的品种之多还居各种稀土新材料之冠。其中,以“屏幕显示”与“照明”两类材料更为突出。加之,其终端应用五光十色,令人目不暇接,且里面既... 在琳琅满目的稀土新材料系列中,发光材料无疑属一重大领域,不仅应用的稀土总量大,其所需单一稀土的品种之多还居各种稀土新材料之冠。其中,以“屏幕显示”与“照明”两类材料更为突出。加之,其终端应用五光十色,令人目不暇接,且里面既蕴藏着巨大的机遇,又面临严峻的挑战。因此,这两种与终端应用多元联系的稀土新材料格外瞩目。 展开更多

Containerization with its increasing share in seaborne trade highlights the importance of assessing container terminals performance indicators. The world economical situation and the global container market have improved slightly after the 2008 world economical crises. Egyptian container terminals are important to serve the world liner services in particular the main east-west routes. Egypt is considered the leading country in Africa and the 18th worldwide in serving the liner markets. Alexandria container terminal as a medium size terminal shows an acceptable super/infra structure facilities and throughput. The analysis of Alexandria container terminal performance indicators from 2007 to 2011 shows a slightly progressive trend. Selected indicators, reflecting production, productivity, utilization and service measures, were used according to the available data. Terminal production shows a slight increasing demand concerning number of vessels and TEUs (Twenty Equivalent Units). Furthermore, productivity indicators proved remarkable development in moves per working hours rather than moves per hours in port, deducing lack of port services accompanying cargo handling. Moreover, Utilization measurements show the terminal occupancy ratio fluctuating from 45% to 67% with slight development. Finally, Service measures show progress in vessels turnaround time, while long wasted time consumed in processes rather than operation was observed. 展开更多
