Abstract(J)エンジン周辺の防音材設計を進めるうえでは,高温環境での音響予測が重要である.本研究の目的は,空気の温度を考慮した理論計算と高温での音響管測定によって,防音材の音響特性の温度依存性について明らかにすることである.

Translation

Abstract(E)Acoustic prediction in a high temperature environment is important in the design of sound absorbing materials around the engine. The purpose of this study is to verify the temperature dependence of the acoustic characteristics of sound absorbing materials by theoretical calculation considering the temperature of air and measurement at high temperature.

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.
