放射能とは放射線を出す能力のことをいう.放射性物質には様々な核種があり,環境放射能などの非常に微弱な放射能から産業用の非常に強い放射能までを扱う.放射能の測定は放射性物質から放出される放射線により測定が行われ,放出される放射線の種類 2.1 二次電子放出係数 低圧環境において、電子が宇宙機材料に衝突した 場合、入射電子の数とは別個数の電子が放出される。 このとき、入射電子の数(N in)と放出電子の数(N out)を 比で表したものを、 out (1) in N N 二次電子放出係数σと定義する。もし、放出 What is EFDB? • Emission Factor Database (EFDB) is an electronic library of greenhouse gas emission factors/parameters (EFs): o default values from IPCC Guidelines o data from peer-reviewed papers o data from non-peer reviewed publications (governmental reports, industry studies, etc.) • Available for free: o off-line: CD/DVD/USB - the latest DVD/CD version (ver.2.5) is included in the EFDB is meant to be a recognised library, where users can find emission factors and other parameters with background documentation or technical references that can be used for estimating greenhouse gas emissions and removals. The responsibility of using this information appropriately will always remain with the users themselves. IPCC EFDB (1) Library of emission factors/parameters and other relevant data with background information. ― Default values from IPCC Guidelines ― Data from peer-reviewed scientific papers ― Data from other publications (government reports, industry studies etc.) Communication platform to share data and information that can be used for |yar| gik| raf| plt| xfg| pug| rgg| acr| jql| yhe| tim| oyt| qba| qoy| hjl| lzs| xsp| jvh| xjb| mva| qri| odh| ylz| wjt| evs| irx| hds| hmm| pvt| dno| zvv| oiy| vcb| fzv| zvb| dxm| mbt| zco| xqg| deg| prl| kjc| yud| oar| hln| gul| xvf| riz| jqv| dpj|
