气象保健、气象治疗与保健舱

气象条件对人类的健康与疾病有着明显的影响。如流行性感冒、心脑血管疾病和风湿性关节炎等发病率与天气变化有密切的关系。这类疾病通常称为气象疾病。恶劣的气象条件会破坏人体的健康状况,带来疾病;适宜的气象条件能保持人体的健康状态,促进机体新陈代谢,增强免疫能力,达到治病、保健的效果。在人类生存环境日益恶化的今天,我们一方面要努力改善、保护大的生态环境,另一方面制作一套人造生活、疗养保健的小气候环境也是简易可行的。为此,设计了一个由计算机自动控制多种气象条件的保健舱方案,如制成产品,推入市场,定能造福于人类。

四川省万县市滑坡群灾害灾情评估

地质灾害的全部过程可以概括为灾前孕育阶段、灾害活动阶段和灾后恢复阶段等三个阶段。对地质灾害灾情评估应包括对灾害灾情进行系统调查、统计、分析和评价等项工作,评估的重点是整个地质灾害形成过程中的灾害活动情况。本文以四川省万县市为例,在论述地质灾害灾情评估理论的基础上,对万县市的地质灾害～滑坡群进行了灾情的评估。

Thermal structure and paleo-heat flow in the Shimanto accretionary prism, Southwest Japan

Abstract Thermal structural analysis and paleo-heat flow estimation provide clues to understanding the thermal evolution of the accretionary complex. The thermal structure and heat flow in the Jurassic Chichibu and Cretaceous to Tertiary Shimanto accretionary complex, Southwest Japan, have been investigated by vitrinite reflectance measurement and fluid inclusion analysis. As a result, the local and multistage metamorphisms were recognized as follows. First, the Tertiary complex around the Miocene Ashizuri granite underwent exposure to extra-high temperatures. Second, the Okitsu Melange underwent exposure to higher temperatures than the surrounding strata and was formed concurrently with the Kula-Pacific ridge subduction beneath the Japanese Islands in the Eocene. Finally, the thermal structure of most of the Cretaceous and southern Jurassic complexes is independent of the geologic structure, indicating that these areas suffered thermal overprint. Regional radiometric dating studies show that most of the Cretaceous Shimanto complex was heated in the Eocene; the thermal overprint might have occurred as a result of ridge subduction. The heat flow during peak heating was estimated to be 95–120 mW/m² except for the Cretaceous Okitsu melange and the Cretaceous Nonokawa formation, north of the Okitsu Melange; a much higher value of heat flow of ~200 mW/m² was estimated in the Okitsu Melange. An estimation of heat flow failed for the non-okawa formation because thermal equilibrium between the fluid and rocks has not yet been reached. It is probable that the southern strata underwent a higher heat flow. Such a trenchward increase in heat flow resembles the present situation of the Nankai Trough, although the heat flow in the Eocene was much higher.
