The moisture content of each sample was arranged from 0 to 60 percent by adding a corresponding amount of water to oven-dried soil, so every sample had the same dry density. It was revealed that the following three formulas are in a good agreement with the results of the experiment. (i) Thermal conductivity of frozen soil varies with temperature in the following relation : K=A\uff65T^B (A and B are constants ; T is the absolute temperature.) (ii) Thermal conductivity and moisture content have the following relation : K=C\uff65e^\u003cD-w\u003e (C and D are constants : w is the moisture content.) (iii) The value of thermal conductivity K_G calculated from the geometric mean by the following formula agrees well with the value of observed thermal conductivity K: K_G \uff1d\uff2b^\u03c6_ss\uff65\uff2b^\u03c6_aa\uff65K^\u03c6_ww\u30fbK^\u03c6_ii, where K_s, K_a, K_w, K_i, express thermal conductivity for soil particle, air, water and ice respectively ; \u03c6_s, \u03c6_a, \u03c6_w, \u03c6_i express volumetric ratio of each component in the same order.", "subitem_description_type": "Abstract"}]}, "item_2_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u5317\u898b\u5de5\u696d\u5927\u5b66"}]}, "item_2_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Seigo, SAWADA"}], "nameIdentifiers": [{"nameIdentifier": "32603", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2016-11-22"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "9-1-14.pdf", "filesize": [{"value": "5.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 5200000.0, "url": {"label": "9-1-14.pdf", "url": "https://kitami-it.repo.nii.ac.jp/record/6443/files/9-1-14.pdf"}, "version_id": "38b4d3b0-cacb-41e1-b4a5-bfbd0ac46ad0"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Temperature Dependence of Thermal Conductivity of Frozen Soil*", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Temperature Dependence of Thermal Conductivity of Frozen Soil*"}]}, "item_type_id": "2", "owner": "1", "path": ["7/15/30"], "permalink_uri": "https://kitami-it.repo.nii.ac.jp/records/6443", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2007-04-09"}, "publish_date": "2007-04-09", "publish_status": "0", "recid": "6443", "relation": {}, "relation_version_is_last": true, "title": ["Temperature Dependence of Thermal Conductivity of Frozen Soil*"], "weko_shared_id": 3}
