For over a thousand years many settlements in Korea forbid the digging of water‐wells. This custom can be explained using geomancy, which personifies local landscapes or names them after animate or inanimate objects. In ‘sailing boat’ landscapes the digging of water‐wells was prohibited because this was viewed as analogous to making a hole in the bottom of a boat, which would thus bring misfortune to local residents. Based on this geomantic reasoning, people considered the custom of forbidding well digging to be an integral part of the art of geomancy, with its origin in a geomantic belief system. My earlier research sustained this explanation but this paper, which is based on two recent instances of field work, rejects the established view on the custom. The aim of this paper is to critically re‐examine this established view and suggests a new idea that the folk custom of prohibiting well digging in Korea was not originally derived from geomancy, but was conceived from a non‐geomantic indigenous Korean idea and have become linked to geomancy through the enforcement process of practicing the custom in traditional Korean society. 相似文献
Deep-well injection has been used to dispose of municipal liquid wastes in southwestern Florida since 1988. The liquid wastes
are injected into an extremely high-transmissivity zone of fractured dolomite in the Early Eocene Oldsmar Formation of the
Floridan aquifer system; this zone is commonly referred to as the Boulder Zone. Data collected during the drilling and operational
testing of southwestern Florida injection wells provide insights into the nature of the injection zone and overlying confining
beds. The location of high-transmissivity zones that are capable of accepting large quantities of waste water is vertically
and horizontally variable and cannot be predicted with certainty. A 40.9-m thick high-permeability interval in one injection
well, for example, was absent in a well drilled only 85.4 m away. Some upward migration of low-density injected fluids has
occurred, but at no site were the injected liquids detected in deep monitor wells, such as occurred at injection-well sites
along the coasts of southeastern, west-central, and east-central Florida. The primary confinement of the injected liquids
(i.e., deepest effective confining beds) consists of unfractured beds of low-permeability dolomite within the Oldsmar Formation,
whose locations are also laterally and vertically variable. The origin and controls of the distribution of fractures in the
Oldsmar Formation are poorly understood.

We have studied the cyclotron-resonance absorption and photoluminescence properties of the modulation n-doped ZnSe/BeTe/ZnSe type-II quantum wells. It is shown that only the doped sample shows electron cyclotron-resonance absorption. Also, the undoped sample shows two distinctive peaks in the spatially indirect photoluminescence spectra, and the doped one shows only one peak. The results reveal that the high concentration electrons accumulated in ZnSe quantum well layers from n-doped layers can tunnel through BeTe barrier from one well layer to the other. The electron concentration difference between these two well layers originating from the tunneling results in a new additional electric field, and can cancel out a built-in electric field as observed in the undoped structures. 相似文献
