Light Reflecting Characteristics of Building Materials and Energy Saving of Nightscape Luminance

In order to realize energy saving of urban nightscape luminance, power consumption was studied with the change of urban luminance. Based on energy consumption indicator(LPD) of 8.9 W/m2, it was calculated that about 0.84W more energy consumption would be for 1 cd/m2 increase of luminance. The effect of 1 to 2 cd/m2 increase was hard to distinguish for human’s visual function under urban nightscape, while the energy consumption was great. Under the same lighting condition, the reflecting characteristics of building surface materials could affect directly the luminance of nightscape. With the study of the reflecting characteristics of different building surface materials, an illumination calculation model for building was proposed based on the formulation of CIE.     

Study on NO2 gas sensing characteristics of In doped ZnO thin films prepared by RF magnetron sputtering

In doped ZnO thin films were prepared on glass substrate by RF magnetron sputtering. The result of XRD and AFM shows that the films are polycrystalline with high c axis orientation. The study of gas sensing reveals that the films are sensitive to NO2 and the best sensibility occurs at 273 ℃; the sensibility is concerned with the concentration of NO2 and the film thickness. The ZnO∶In films are more sensitive to the NO2 gas with higher concentration of NO2 and thinner films have a better sensitivity. Exposed to 2×10-5 NO2 at 273 ℃, the 90nm thick film has a sensibility of 16, indicating that ZnO∶In films can be used to measure NO2 with a low concentration.

医疗保险对长期住院贫困精神分裂症患者的影响

目的了解长期住院的贫困精神分裂症患者在参投医疗保险后,其临床治疗与生活质量的变化。方法以在中山市第三人民医院住院2a以上并在2008年1月1日至2008年6月30日间参投医疗保险的精神分裂症患者为研究对象,对其参保前后的住院医疗费用、抗精神病药物使用情况、医疗相关服务、药物副反应、临床疗效、生活质量等方面进行自身对照比较。结果患者投入的医疗费用增加（P〈0．01）,抗精神病药物使用以非典型为主,药物副反应减少（P〈0．01）,生活质量有所提高（P〈0．05）。结论医疗保险对长期住院贫困精神分裂症患者的康复治疗及生活质量有积极影响。     

基于回归分析建立补充耕地数量质量实行按等级折算数学模型的研究

目前,我国在执行占用耕地补偿制度中存在以数量进行平衡,而忽视质量平衡的问题,导致占用耕地与补充耕地质量不对等,土地综合生产力下降。本文以回归分析为原理,通过对自然质量等指数、利用等指数、经济等指数及其所对应的实际标准粮产量进行回归分析,建立了数学模型,计算出不同等别间的折算系数,为云南省补充耕地数量质量按等级折算提供依据。

为更加深入地了解土壤颗粒对137Cs分布的影响,选取新疆准噶尔东部地区沙土、灰棕漠土和灰漠土3种主要的土壤类型,探讨不同土壤类型及自然地理环境条件下137Cs与土壤颗粒的关系.结果表明:沙土、灰棕漠土和灰漠土均以>50μm的颗粒占据主导地位,其占比介于51.35％～90.22％,中值粒径(D50)表现出风沙土>灰棕漠土...     

面向生态系统多对象保护与修复的水库优化调度

近20 a来,随着塔里木河(简称"塔河")流域水资源综合规划与调度的实施,已基本实现"水流到台特玛湖、大西海子水库多年平均下泄3.50×108 m3"的生态输水目标.但是,塔河下游其文阔尔河与老塔里木河之间的两河区域内植被稀少、生态环境脆弱,多年的生态恢复效果并不显著.鉴于此,本文以大西海子水库为调控主体,以大西海子下...
