Background: The practice of vegetarian diet in Taiwan is more widespread. Because of vegetarian diets offer a number of advantages to health. But several studies indicated that vegetarian diets had a risk of some nutrition deficiency. Objective: The aim of this study was to assess and compare the dietary intake and nutritional status of vegetarian and omnivore preschool children and their parent.

背景介绍：由於素食对於健康和环境保护有许多好处，因此在台湾素食人口有越来越多的趋势，但是一些研究显示素食会有一些营养素缺乏之危险，儿童期正处於生长发育的阶段，是否素食会影响幼儿的生长发育是许多人关心的议题。

Base on the problem of large quantity fatigue loads on corroded R.C. structure and small quantity study of its mechanical property, bending resistance fatigue test of corroded R.C. beams is discussed in this paper. The influence of stress ratio and re-bar weight loss ratio on bending resistance fatigue performance of corroded R.C. beams are researched, and the relation between strains of corroded re-bars and fatigue life of beams are obtained. The main research contents and conclusions are as following: 1. Under the fatigue loads, the overstrain of concrete approximately coincidences three stages strain development and accumulation rule, and the mechanical property of concrete is deteriorated. The fatigue damage of concrete is accumulated. The overstrain of re-bars increases and the increase rate decreases.

鉴于实际工程中大量存在腐蚀钢筋混凝土结构承受反复荷载作用，但其力学性能研究不多的问题，本论文进行了锈蚀钢筋混凝土梁抗弯疲劳试验，研究了应力比和钢筋锈蚀率对锈蚀钢筋混凝土梁抗弯疲劳性能的影响，得出了锈蚀钢筋的应变与构件疲劳寿命之间的关系曲线，主要研究内容及结论如下：(1)在循环荷载下，混凝土残余变形基本符合三阶段变形规律，力学性能劣化，疲劳损伤积累。

Green Railway Alignment Selection,means that solution is obtained to avoid all the environment sensitivity problem at the layout and design stage of railroading item and in the process of railway route selection,nature condition such as landform、geology、hydrology and so on,especially influence of landscape、nature protection area and entironment on railway scheme must be considered.

铁路绿色选线，是指将各种环境敏感问题的规避解决在铁路建设项目规划设计阶段，也就是在铁路选线中融入环保理念，在线路方案比选中综合考虑地形、地质、水文等自然条件，特别要考虑风景名胜区、自然保护区及生态环境因素对线路方案的约束，多方案进行环境影响的综合评价，选择出对环境影响最小的方案。
