          <datacite:description descriptionType="Abstract">現今の衝撃波捕獲スキームを構成する際の骨格として用いられる近似リーマン解法の特性を調べた。次いで新らしい型の近似リーマン解法を提案した。それはHLLEMスキームを改良した1つの結果であり、正値条件とエントロピー条件とを満す。また、その手法の高温気体などの非平衡流れへの一般化についても述べた。同じく数値計算結果についても示した。</datacite:description>
          <datacite:description descriptionType="Other">Investigated are characteristics of the approximate Riemann solvers, which are used as a building block for construction of modern shock-capturing schemes. Then a new approximate Riemann solver is proposed, which is a result of an improvement of HLLEM (Harten Lax van Leer Einfeldt Modified) scheme, satisfying the positivity condition and entropy one. Also its generalization for nonequilibrium flows such as high-temperature gas is described. Some numerical results are presented as well.</datacite:description>
