浅析导致事故的心理因素

事故的心理因素是指影响一个人的行为从而导致事故发生的心理状态和成分的总称。就情绪、性格、气质等心理因素对事故的影响进行分析所得出的结果表明,心理因素对事故的影响主要体现在以下方面。     

铁炭内电解预处理阿维菌素废水

采用铁炭内电解预处理阿维菌素废水，当原水pH为3.7、COD为31600mg/L、AVM含量为204μg/L时，最佳工艺条件为铁炭比1：1、停留时间30min、混凝pH8－9时，废水COD和AVM的去除率分别达到19.5%和68.5%，为后续生化处理创造了有利条件。

Prevalence of drink-driving among adults in China: A nationally representative survey in 2010

Objective: We examined the prevalence of and characteristics associated with drink-driving in China. We compared this study's drink-driving findings with those from the United States to explore how effective traffic safety interventions from Western cultures might be adapted for use in China.

Methods: Data from the 2010 China Chronic Disease and Risk Factor Survey were analyzed to describe the prevalence and characteristics associated with drink-driving in China.

Results: Overall, 1.5% of Chinese adults reported drink-driving in the past 30 days—3% of males and 0.1% of females. However, among males who had driven a vehicle in the past 30 days and consumed at least one alcoholic beverage in the past 30 days, 19% reported drink-driving during the 30-day period. Excessive drinking, binge drinking, nonuse of seat belts, and having been injured in a road traffic crash in the past year were most strongly associated with drink-driving among males.

Conclusions: Drink-driving is prevalent among male drivers in China. Although large differences exist between China and the United States in the proportion of adults who drive, the proportion who consume alcohol, and some of the personal characteristics of those who drink and drive, similarities between the 2 countries are present in patterns of risk behaviors among drink-driving. To reduce injuries and deaths from drink-driving, effective interventions from Western cultures need to be tailored for adoption in China.     

湖北气象灾害的特点及防御对策

通过分析大量的气象灾害资料,并与其它自然灾害相联系,将发生在湖北的气象灾害进行了归纳,将其划分为6大类18种,并对其影响作了简要的描述．同时,根据历史上湖北气象灾害发生发展的时空分布规律以及气象灾害之间的相互联系,找出了湖北气象灾害发生的特点．最后,从减轻自然灾害的角度出发,针对湖北减灾工作的实际,提出了相应的防御对策．     

常用钻井液填加剂对钻井污水化学需氧量的影响

针对石油工业钻井污水化学需氧量（ＣＯＤ）严重超标的状况,从分析测定目前油田常用的８种钻井液添加剂的ＣＯＤ入手,探讨了钻井液添加剂对钻井污水的影响。实验结果表明：８种钻井液添加剂按油田现场配比复配后,对钻井污水ＣＯＤ的影响程度各不相同,其大小依次为：柴油、ＨＰＡＮ、磺化沥青、ＰＡＮ、ＰＡＭ－１、ＦＡ－３６７、ＸＹ－２７、ＣＭＣ;钻井污水中ＣＯＤ值严重超标的主要因素是钻井液添加剂;并且钻井液添加剂浓度与其对应的ＣＯＤ之间存在良好的一元线性关系。根据一元线性回归方程可较好地预测油田现场各钻井液添加剂对ＣＯＤ的影响,为解决钻井污水处理这一难题提供科学依据。     

气水比对印染废水生化处理效果的影响

通过实验室分析，对接触氧化池中4种不同的气水比的处理效果进行了试验，结果表明，当接触氧化池中的气水比达到15：1的时候对水中污染物的去除最为有效。     

香港地区土壤中的γ辐射本底值研究

本文报道香港地区土壤的γ辐射本底值的测定方法.测得该地区以碘化钠晶体在1m高度的γ辐射吸收剂量率平均值为70.7mrad/a(γ能量下限为100keV).若按90kvV以上计.平均值则上升11％.测定结果表明,珠江沉积地带及水塘区的环境辐射较强,工业区辐射本底值也显著地高,而海水冲刷地带的本底值较低.     

挥发性卤代烃的天然来源及其生成机制

天然产生的挥发性卤代烃(VHC)，对大气中VHC的源汇平衡有显著影响。不同生态系统中VHC的天然生成机制存在很大差异，有许多天然过程还不为人们所了解。该文对海洋，陆地等生态系统中VHC的天然来源及其产生机制进行了较全面的综述。
