| 1 | Prevalence and risk factors of erectile dysfunction in three cities of China: a community-based study显示文摘Aim:To determine the age-adjusted prevalence of erectile dysfunction (ED) in 3 big cities of China and to explore its potential sociodemographic, medical and lifestyle correlates. Methods: A crosssectional, population-based survey was conducted in three cities of China. Structured questionnaires were administered to 2 226 men, aged 20-86 years, by trained interviewers. Results: The age-adjusted prevalence of ED was 28.34% (mild 15.99%,moderate 7.14%, severe 5.21%). In the men above 40, the prevalence was 40.2%. Age was positively correlated with ED (P<0.01). Education was negatively correlated with ED (P<0.01). Spouse companionship, living condition were positively correlated with ED (P<0.01). Histories of cardiovascular disease, diabetes, and hyperlipidemia were positively correlated with ED (P<0.01). Cigarette smoking was not correlated with ED (P>0.05), while the cigaretteconsumption and duration were positively correlated with ED (P<0.01). Alcohol drinking is negatively correlated with ED (P<0.01). The duration of drinking was positively correlated with ED (P<0.01). Weekly alcohol consumption was not correlated with ED (P>0.05). Conclusion: The prevalence of ED increased with age. Cardiovascular disease, diabetes and hyperlipidemia were positively correlated with the increased prevalence. Sociodemographic and lifestyle factors, such as education, spouse companionship, living condition, cigarette and alcohol consumption or duration also have association with the prevalence of ED.

| 2 | 橄榄石单晶体高温蠕变显示文摘作者首次采用中国河北省万全县大麻坪橄榄石单晶体做原始变形实验材料,在温度1200~1500℃,应力16~175MPa,氧分压10^(-4)~10^(-10)atm条件下,对土地幔流变学的以下三个问题进行了深入研究:(1)化学环境(即氧分压和斜方辉石缓冲剂)对橄榄石流变性质的制约作用;(2)详细测定橄榄石单晶体流变参数和建立流变本构方程;(3)对橄榄石单晶体[110]_c方向的三个蠕变机制进行研究,这些新的高温实验成果第一次为研究中国东部岩石圈动力学提供了有意义的定量资料。 | 金振民 QuanBai D.L.Kohlstedt 金淑燕 | 1993 | 地球科学(中国地质大学学报)1993，18，1： | 3 |
| 3 | 橄榄石中氢的实际溶解度及其对地幔中水储存的意义显示文摘水在地球上地幔的地球动力学过程中起着重要的作用,例如,氢(正如水)能影响部分熔融产生的岩浆的数量和组成,而微量氢(~0.001wt%的水)可使土地幔的主要矿物──橄榄石弱化。氢离子的迁移可能是造成较流圈异常高的电导率的主要原因。氢在地幔过程中的重要性必然取决于无水橄榄石中所储存的氢或水的数量以及氢在橄榄石晶格中所处的位置。本文报道了橄榄石单晶的水热实验结果,该实验表明,在1573K和50~30MPa下橄榄石能容纳0.0034wt%的水。氢的溶解度分别取决于氢逸度的一次方和氧逸度的二分之一次方,表明氢离子与氧的间隙或镁的空位有关。将我们的数据外推至大洋地区~100km深处,可得出氢的实际溶解义(0.03wt%的水),经证实橄榄石可能确实是上地幔中氢的主要储体。 | QuanBai D.L.Kohlstedt 宋茂双 | 1994 | 地质地球化学1994，，1： | 0 |
