Abstract(J)自動車等の微小粒子状物質(PM) 排出規制がより厳しくなる中,低濃度PM計測の課題の一つがバックグラウンドPMの低減である.画像処理での測定手法を従来フィルタ重量法と比較して,効率良い希釈トンネル汚染監視システムとして有用かを検証し,0.95以上の相関と0.02mg/mile相当の分解能を確認した.

Translation

Abstract(E)As regulations on particulate matter (PM) emissions from automobiles and other sources become stricter, one of the challenges in measuring low-concentration PM is reducing background PM. A measurement method using image processing was compared with the conventional filter weight method to verify its usefulness as an efficient dilution tunnel pollution monitoring system. As a result, we get a correlation coefficient of 0.95 or higher and a resolution equivalent to 0.02 mg/mile.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
