随着人们的寿命日益延长,替换人体部分劳损器官已经成为医学界的新领域。大多数出生于1900年的婴儿不到50岁就去世了;100年后英国人的预期寿命现已超过80岁,到2030年前65岁以上老人的数量预计会翻倍。这种趋势急剧改变了人口的年龄构成并向工程师提出了一系列新挑战。其中一项最重要的挑战便是要让人们在老年拥有更高品质的生活。

With the extension of people’s life expectancy, the replacement of part of the human organ has become a new field of medical profession. Most infants born in 1900 died in the late 1950s; the life expectancy of the British population now exceeds 80 years after 100 years and the number of older persons over the age of 65 by 2030 is expected to double. This trend has dramatically changed the age composition of the population and posed a series of new challenges to engineers. One of the most important challenges is to make people have a higher quality of life in old age.
