文章摘要：摘要：本文分析了现有几种常用的锅炉给水除氧技术，如物理除氧，化学除氧，电化学除氧，并指出这些方法各自不同的适用范围。

The deoxygenation method which is often used in China at the present,both physical method(heating power deoxygenation ,analysis deoxygenation ,vacuum deoxygenation )and chemical deoxygenation (hurling Na-2SO-3 method directly,Fe filings method,hydrazine method) have a certain problem when is used in middle or small boiler supply water.

Our country is becoming a community which has more and more senile people. Owing to debility on physiology and psychology, descension on social class of senile people, there will be some change on traffic characteristic and traffic demand of them. So it is necessary to study the applicability of pavement for senile people.

我国已进入老龄化社会，而高龄人群由于生理特性的衰退、心理特性的改变以及社会地位的下降，导致其交通行为特性与交通需求都发生了变化，因此，对作为高龄人群最常用出行方式载体的人行道系统进行是否适应高龄人群特性的研究就显得很有必要。
