唐崖土司城宫殿区遗址复原初考

宫殿区是中国古代城池中核心的部分,是最重要的建筑类型。唐崖土司城宫殿区遗址是鄂西地区土司城宫殿区遗址的典型代表,具有很高的研究价值。宫殿区原有的建筑风格既体现汉族官式建筑的特点,又融入了土家族特有的建筑形制。本文从整体平面格局、建筑单体形制特征等方面在现有的资料基础上对唐崖土司城宫殿区遗址进行了初步复原,为进一步还原其真实性提供参考依据,以期为研究土司时期建筑技术与艺术有一定的借鉴意义。     

南宋临安城太庙建筑遗址复原探讨

1995年—1998年,杭州市文物考古研究所对位于杭州市太庙巷一带的南宋临安城太庙遗址进行了考古发掘,发掘总面积近1100m2,发掘出的建筑遗址包括东围墙、东门址、砖铺道路、房屋基址、散水、排水沟等,可知南宋临安城太庙是一个功能布局完善、规模宏大、建造做法考究的建筑组群。结合相关历史文献的梳理分析,对南宋临安城太庙的建制始末、范围与布局、主殿建筑形制等进行全面的研究与探讨。

西汉营造尺尺度初探*

营造尺与建筑营建密切相关,营造尺尺度的考证是古代建筑研究和复原设计的基础,但目前学界对西汉时期的营造尺尺度的认知存在巨大分歧。本文在已有研究的基础上,依据历史文献、出土实物尺和西汉重要建筑遗址的考古资料,对西汉营造尺尺度进行辨析,认为一尺取 23.1 厘米为宜,且依据实际情况具体数值可在上下 5% 范围内浮动。

Fracture dilation during grouting

Sealing underground excavations from ingress of water constitutes a large part of both the cost and the risk for many infrastructure projects. In this paper we present a mechanical model for the rock mass response when grouting hard jointed rock. The model predicts a stiff and a non-stiff behaviour and a transition between them that is dependent on the relationship between the grouting pressure and the in situ stress conditions. The predictions are consistent with previously published measurements and explain grouting behaviour that has been difficult to model with previous methods.

Water ingestion during water recreation

Quantitative risk assessments have estimated health risks of water recreation. One input to risk assessment models is the rate of water ingestion. One published study estimated rates of water ingestion during swimming, but estimates of water ingestion are not available for common limited contact water recreation activities such as canoeing, fishing, kayaking, motor boating, and rowing. In the summer of 2009 two related studies were conducted to estimate water ingestion during these activities. First, at Chicago area surface waters, survey research methods were utilized to characterize self-reported estimates of water ingestion during canoeing, kayaking, and fishing among 2705 people. Second, at outdoor swimming pools, survey research methods and the analysis of cyanuric acid, a tracer of swimming pool water, were used to characterize water ingestion among 662 people who engaged in a variety of full-contact and limited-contact recreational activities. Data from the swimming study was used to derive translation factors that quantify the volume of self-reported estimates. At surface waters, less than 2% of canoers and kayakers reported swallowing a teaspoon or more and 0.5% reported swallowing a mouthful or more. Swimmers in a pool were about 25-50 times more likely to report swallowing a teaspoon of water compared to those who participate in limited-contact recreational activities on surface waters. Mean and upper confidence estimates of water ingestion during limited-contact recreation on surface waters are about 3-4 mL and 10-15 mL, respectively. These estimates of water ingestion rates may be useful in modeling the health risks of water recreation.     

Aminopolyphosphonate removal during wastewater treatment

Phosphonates are used in large quantities in industry and household products as scale inhibitors and chelating agents. They are not biodegraded during wastewater treatment but are removed by adsorption processes. Field measurements from different wastewater treatment plants affirm that they are removed almost completely during wastewater treatment. Adsorption of nitrilotrismethylenephosphonic acid onto activated sludge, amorphous iron oxide and humic acids (HAs) was studied under controlled conditions. The adsorption onto HAs decreases sharply with increasing pH with negligible adsorption at pH above 6.5. Adsorption onto amorphous iron oxide follows a Langmuir behavior. The presence of 1 mM Ca doubles the maximum surface capacity at pH 7. Adsorption onto activated sludge is not very pH sensitive and is explained to a large extent by adsorption onto amorphous iron oxides, but the contribution of organic matter or other mineral phases cannot be ruled out.     

暴雨来袭如何自救

面对极端天气的增多、增强的趋势,人们应注意了解最新预报、预警信息,此外,应主动学习不同天气里相应的防范措施,才能有备无患。特别是在城市里,当驾驶员发现立交桥下等低洼区有积水,应停车或避开;在山区,应特别注意防范强降水汇流形成的山洪、地质灾害。当暴雨来临时,人们应该学会如何逃生与自救。
