目的:观察疾病状态人群面色光谱色度情况,为疾病状态五脏病评价提供可供依据。方法:采用日产柯尼卡美能达CM-2600d分光测色仪,观测健康组(183例)、疾病组(370例)额部、眉间部、鼻部、下颏、左右颧部、左右眼胞8处明亮度l、红光度A、黄光度b、饱和度C值及波长段(400~700nM)下的面色反射率值等指标,并据中医理论对疾病状态进行五脏病位分析。结果:疾病组l值显著低于健康组,b、C值均显著高于健康组;疾病组各波长段下反射率显著低于健康状态组(P<0.05)。疾病组除左右眼胞外的6个位点间的l、A、b、C值有显著性差异(P<0.05),不同点位有其特异性的色度变化特征。疾病组五脏病各组光谱色度特征比较有显著差异(P<0.05),结果与中医面部脏腑五色理论在一定程度上相符合。结论:运用光谱色度测定方法,可以作为诊断疾病状态五脏病的重要指标。Objective: To observe disease status facial spectrum and color,providing good quantitative basis for disease assessment.Methods: We gathered the facial color information in health(183) and disease groups(370) including L,a,b,C values and reflection of different wavelengths in 400-700nm with CM-2600D spectral photometric color measuring instrument on 8 points including frontal part,glabellas nose,mandible two cheeks and eye cells and analysized disease status five-zang positioning according to the principle of TCM syndrome differentiation.Results: L value of Disease group was lower than health status group and b,C values were higher than health status group,reflection of different wavelengths of disease group were lower than health group(P<0.05).6 points in disease group between loci L,a,b,C values with varying degrees of significant differences(P<0.05).Different point had its own specificity facial complexion variation characteristics.Facial spectrum and color of each five-zang disease group had significant difference through comparion of facial complexion.To a certain extent the result was consistent with TCM facial organs Five-color theory.Conclusion: There existed diagnostic value in distinguishing five-zang disease status in some degree by spectral photometric color measuring technique.国家科技支撑计划(No.2012BAI37B06);国家高技术研究发展计划(863计划)资助项目(No.2008AA02Z407);国家自然科学基金资助项目(No.30873463;No.81173200);国家自然基金青年项目(No.81102558);上海市重点学科(第三期)建设项目(No.S30302;No.S30303)---

On Forecasting. and Adjustment to Housing Price in Xiamen Based on ARIAM Model

中国的房地产市场经历了2010年限购,2014年解除限购,2016年的再次限购的政策调整。厦门住宅价格一路攀升,增幅超越了北、上、广、深,位居全国第一,引发全国关注,对厦门住宅价格的预测和调控的研究有一定现实意义。本文拟通过对厦门自2012年元月-2016年10月的平均住宅价格数据,结合spss17.0版软件,用时间序列分析中的ARIMA（1,2,1）模型,对2016年10月以后的厦门住宅价格预测及调控进行研究。The real estate market in China experienced a various policy adjustment in the past few years -- the house purchase limitation in 2010, the release of house purchase limitation in 2014, the house purchase limitation again in 2016. The housing price in Xiamen has increased gradually and the growing rate has surpassed that in Beijing, Shanghai, Guangzhou and Shenzhen, coming in first in China, which arouses attention all over the country. Hence, the study on the forecasting and adjustment to the housing price in Xiamen is of realistic significance. The paper applies ARIAM model to make a research on the average housing prices in Xiamen from January 2012 to October 2016, tending to forecast the housing price after Oc, tober 2016 in Xiamen

温度对施肥滴灌系统滴头堵塞的影响

为探究不同灌水温度下水肥一体化滴灌滴头堵塞成因与过程，采用固定周期间歇滴灌的多因素完全随机试 验设计方法，分别在冬、夏两个季节研究了3 种不同泥沙级配浑水与3 个不同施肥质量浓度组合对滴头堵塞的影 响和堵塞变化过程。结果表明，灌水温度是影响滴头堵塞的重要因素，与水质交互耦合效应显著，夏季施肥和未施 肥2 种情况下灌溉滴头的抗堵塞性能均高于冬季，夏季有效灌水次数是冬季的1. 26 ～ 1. 43 倍; 施肥加速滴头堵塞 的作用受泥沙级配和灌水温度的影响，冬季灌溉水中0. 034 ～ 0. 1 mm 粒径粗颗粒含量越多，施肥质量浓度对堵塞 的影响越敏感，夏季灌溉水中0 ～ 0. 034 mm 细颗粒越多，施肥质量浓度对堵塞的影响越敏感。建议灌水温度较低 时，水肥一体化滴灌应控制在较低的施肥质量浓度下灌溉，适当增大次灌水时间，减少灌溉次数。</p

Ni/石墨封严涂层的盐雾腐蚀研究

采用热喷涂技术制备了Ni/Al-Ni/石墨系统封严涂层,研究了涂层在盐雾环境中的腐蚀性能。结果表明：Ni/石墨涂层在5%NaCl饱和氧溶液中（质量分数,下同）的腐蚀电位为-382.3 mV,在去氧溶液中的腐蚀电位为-848.2mV。Ni/石墨面层经盐雾腐蚀后,腐蚀产物主要为无定形Ni（OH）2.xH2O,腐蚀导致涂层表面石墨掉落,涂层腐蚀失重与腐蚀时间遵循幂指数函数。在腐蚀初始阶段,涂层的结合强度变化不大,但是经过480h的腐蚀后,涂层的结合强度明显下降,960h时结合强度与初始值相比下降30%左右。腐蚀机理研究表明,由于Ni/石墨涂层内部存在孔隙,腐蚀介质沿着孔隙通道向内渗透。孔隙中充满腐蚀介质后涂层内外溶液交换困难,在涂层的表面和内部形成宏观腐蚀电池,加速了涂层内部金属相的腐蚀
