residential densityとは 意味・読み方・使い方

The electric conductivity of raw water to which sodium carbonate or potassium carbonate is added is adjusted so as to be 10-300 mS/m, and the product of the density of current flowing between anodic and cathodic both electrodes in an electrolytic cell and the residential time in the electrolytic cell upon the electrolysis of the raw water is set so as to be 1.3-60 secA/dm^2.例文帳に追加

炭酸ナトリウム又は炭酸カリウムを添加した原水の電気伝導度を１０〜３００ｍＳ／ｍになるように調整し、電解槽の陽陰両極間に流れる電流の密度と、原水の電解時における槽内滞留時間とを乗じた積を、１．３〜６０ｓｅｃＡ／ｄｍ2となるように設定する。 - 特許庁

Regarding this point, a survey undertaken by a workshop consisting of officials selected from applicants from the city office of City J, which has a population of 300,000, found that as the city's DID area had approximately doubled over the past 30 years and the population density had dropped to approximately 70%, a decline in population density on account of the spread of the central urban area should be avoided if the level of services for maintaining urban facilities is to be maintained while keeping the burden on residents in check and taking into consideration effective use of existing urban facilities. This makes it important to encourage the return of populations to districts that form the core of cities, and to pursue "compact town development" bringing together residential functions and urban functions.例文帳に追加

この点に関して、人口30万人規模のJ市について、同市役所内で公募された職員による研究会が行った調査によれば、同市では過去30年間でDID面積が約2倍に拡大し、人口密度が約7割に低下したため、既存都市施設の有効活用を考慮し、住民負担を抑制しつつ、都市施設の維持に係るサービス水準を維持しようとすれば、市街地の拡散による人口密度の低下は避けるべきであり、都市の核となる地区への人口回帰を図り、生活の諸機能や都市機能が集合した「コンパクトなまちづくり」を目指すことが重要としている。 - 経済産業省
