查询词典 ventilation installation

Results The factors including age, exercise, the exposure time to cell phone and computer, refurnishing houses, ventilation, supplementary of folic acid, favoring frying food, reproductive knowledge, premarital consultation, parity, the opportunity of plan for conception and occupational stress were significant different between case and control groups (P.05). Logistic revealed that exercise (OR=0.319), ventilation (OR=2.496), supplementary of folic acid (OR=2.365), age (OR=1.106) and occupational stress (OR=2.159) were in the regressive model.

In order to solve the frost heave and thaw settlement, the model tests were made in Tibetan Plateau. Two kinds of model were designed to horizontal drain structure embankment and the ventilation embankment in suit. The effect of horizontal plastic drain was analyzed in contrast with the ventilation embankment. The mechanisms of horizontal plastic drain were studied in permafrost, such as gravity draining in the superficial layer and structure stiffing in the embankment in the theory. According to the design theory, the parameters of horizontal plastic drain were confirmed in the embankment. The values of deformation were inspected by fiber monitor system in the permafrost embankment.

为了解决青藏高原的冻土浅层雨季雨水下渗和蒸发所产生的冻土冻胀与融沉问题，在青藏高原开展水平排水板结构性路基和普通通风路基的原位模型对比试验，并从理论上探讨水平排水板在多年冻土路基中浅层重力排水和结构加劲的作用机理，确定水平排水板的铺设参数；运用光纤监测技术对水平排水板在多年冻土路基中的变形进行监测，对比分析水平排水板铺设与否这2种条件下冻土路基变形监测结果。
