PRELIMINARY STUDY OF INDOOR FEATURES OF TEMPERATURE AND HUMIDITY FOR ROOMS FACING NORTH-SOUTH IN WINTER IN A LOW-LATITUDE PLATEAU CITY

Analyzing observations of wintertime air temperature in both indoor and outdoor surroundings in Kunming, a city lying in low latitudes, characteristics of temperature and humidity have been studied for the interior of rooms facing north-south under different weather conditions. Significant warming effect has been identified in terms of lowest and daily-mean indoor temperature in the area of Kunming. The heating amplitude ranges from 7.7°C to 10.0°C and from 4.6°C to 5.8°C for the interior part of rooms facing the south and from 4.6°C to 7.0°C and from 1.3°C to 4.4°C for the interior part of rooms facing the north, respectively for the two elements. The highest air temperature is higher indoor than outdoor for rooms facing the south, but otherwise is usually true for rooms facing the north. Additional findings point out that buildings not only help maintain relatively warm indoor temperature but delay its variation. The diurnal cycle of temperature indoor is smaller and ranges by 40% ~ 48% for south-facing rooms, and by 20% ~ 30% for north-facing rooms, than outdoor, and the highest temperature is about 2 hours late inside the room than outside. It shows how inertly indoor temperature varies. The work also finds that relative humidity is less indoor in southward rooms than in northward ones and difference is the largest on fine days but the smallest when it is overcast. For the diurnal variation, the indoor relative humidity is large at nighttime with small amplitude but small during daytime with large amplitude. The above-presented results can be served as scientific foundation for more research on climate in low-latitude cities and rational design of urban architectures.

水化地震短临前兆标志体系的研究

应用层次性和整体性原理等新观点，从大量的水化观测资料中，提炼出水化前兆标志。该标志以强震和强余震为目标，从中期、短期和短临３个时间尺度上，对其发生的时间和地点进行跟踪预测。预测的标志有均值变化率、频次变化速率、频次累加曲线和从属函数等４类。讨论了提取４类标志以及判断时间和地点的方法，并详述了不同时间尺度的震情判断方案。对１９７６年唐山地震做了检验性预测，效果良好。     

三峡库区巴东地区紫红色泥岩的崩解特性研究

在地制裁调查及大量岩土实验的基础上,研究了巴东县新城区中三叠统巴东组二段T2b^2紫红色泥岩的膨胀崩解特性。测定了强风化泥岩的矿物及化学成分,对岩石在不同状态和不同浸水时间条件下表现出的快速胀裂、崩解现象进行了细致观察,同时对不同浸水状态的岩石进行了强度试验,发现该区紫红色泥岩风化后具有微弱的膨胀性,以及沿微裂面快速崩解的特性,其膨胀崩解特性与岩石的物理状态密切相关。     

南岭科学钻探(NLSD-1)矿化规律与深部找矿方向

南岭科学钻探(NLSD-1)是目前中国在华南金属矿集区内实施的最深钻探工程,总进尺2967.83 m,揭露金银铜铅锌和钨铋铀各类矿化120余处,矿化层可分为破碎带型、硅质脉型、长英质脉型,以微细脉、细脉、网脉状、浸染状、块状形式产出,其中达到工业品位的矿脉具有3段,多处矿化可侧向追索,具有潜力工业矿体。元素垂向矿化规律上表现为金银铜、铅锌矿化分别以组合形式出现,铋的元素异常与亲硫元素矿化具有明显相关性,其中贵金属矿化异常集中在推覆体内,而钨锡铀矿化向深部有增强趋势,两者在钻孔内具有较明显的岩性地层、构造和岩浆岩的专属性特征。根据NLSD-1揭露的垂向矿化规律,结合区域成矿规律研究成果提出四大找矿方向,即:推覆体内V10~V31向东向深部延展、推覆体下部钨铋多金属矿化、深部3个空间位置可能出现的厚大矿体以及外围高山角—井笔山一带斑岩型-爆破角砾岩型矿化。     

日本西南冲岛新生代过铝质花岗岩类的特征和成因

日本西南冲岛花岗岩类按岩性可划分出两种类型:谷尻型(Tanijiri type)堇青石-紫苏辉石花岗闪长岩和母岛型(Mashima type)电气石-石榴石黑云母花岗岩。两者均以中等过铝质,高的钛铁矿/磁铁矿比值、高的Rb/Sr比值和中等至强的负铕异常等指示其成因上应归属于钛铁矿系列花岗岩,与澳大利亚的S型花岗岩有相似之处。谷尻型花岗闪长岩的源岩主要为一套中性-中基性变质火山岩和火山沉积岩。由于未经充分的沉积分异,成熟度低,含放射成因~(87)Sr较少,由这种源岩经部分熔融形成的初始岩浆具有较低的I_(Sr)~t值(0.70765)和较高的ε_(Nd)~t值(-6.3),这些又不同于典型的S型花岗岩。根据Rb/Sr模拟计算,母岛型花岗岩可能是谷尻型花岗闪长岩浆经26～65％结晶相分离结晶后的产物。

华北强震迁移与前兆异常转移的某些关系

1966年至1976年在华北相继发生的邢台、渤海、海城、唐山4次7.0级以上强震的震后异常与后续地震有某些的关系。这种关系主要表现在异常的起始时间与转折时间上,同时还表现在异常点的优势分布方向及其逐渐转移的进程上。研究这种关系对于判断同组强震的迁移趋势有一定的实用价值。
