ISO 8466-2:2001 水质 性能特征分析方法和评价方法的校准和计算 第2部分:使用非线性二级校准方程的方法

It is not always possible to accurately describe the relationship between a set of calibration points with a rectilinear curve, even by decreasing the working range. Instead of the linear regression analysis, a least-squares fit to a second-order polynomial is applied (see test for linearity in 4.1.3 of ISO 8466-1:1990l1]). Using this fit, it is possible to calculate not only the calibration function but also the confidence interval associated with it. This part of ISO 8466 is intended primarily for use in method development and may not necessarily be applicable to all routine analyses.

ASCE 33-01-2001 综合跨界国际水质管理协议

The purpose of Comprehensive Transboundary International Water Quality Management Agreement is to provide a model for comprehensive water quality planning and management of shared water resources. This model agreement is based on the concept of shared sovereignty and is appropriate only for those situations in which the Parties are prepared to relinquish a significant degree of sovereignty over their portion of the shared water resource. The agreement is extensive and considers most aspects of planning and management of water resources. The objective of this comprehensive, integrated agreement is to achieve allocation based on equitable utilization. The intent of this agreement is to be sufficiently flexible for use on an international scale and in a variety of geopolitical settings.

ASTM D6523-00 垃圾堆积场的代用日掩盖物的评价和选定的标准指南

1.1 This guide is intended to assist specifiers and end users in assessing the different options available for sanitary landfill daily cover materials described as alternative (non-soil) daily covers (ADCs). Traditional daily cover consists of at least 6 in. of soil spread over the working faces of sanitary landfills. Alternative systems are attractive to landfill operations in order to conserve landfill disposal space, among other reasons.1.2 This guide assists in understanding different performance features of broad classifications of ADCs, and determining the extent and degree to which different ADCs are able to "control disease vectors, fires, odors, blowing litter, and scavenging, without presenting a threat to human health and the environment," as intended by United States Environmental Protection Agency (USEPA) regulations.1.3 This guide is not intended to provide cost information regarding the various ADCs as a standard guide, it does not dictate a protocol for the practice and testing of ADCs, but rather provides valuable information, guidance, and recommendations to interested parties concerning the many options available.
