saal
解釋
薩爾-
A two - cylinder model for saal incorporating bem simulations is proposed, which introduces a factor concerning the geometric parameters of the levitator into the expressions for the time - averaged potential u, acoustic radiation force f, and restoring force constant ki, respectively, and builds up the relationship between the levitation capabilities and the geometric parameters of a single - axis acoustic levitator
建立了單軸式聲懸浮的優化設計理論模型，採用邊界元方法求解入射聲場，在表徵聲懸浮性能的時間平均勢u 、聲輻射力f _ i和回復力常數_ i的表達式中分別引入了一個涉及懸浮器幾何參數的因子。 -
The advantage of al is its applicability to non - conducting substances and also to low - melting - point metallic materials. due to the fact that the levitation capability of single - axis acoustic levitation ( saal ) is comparatively weak and its applications are mainly limited to low - density substances, this paper aims at enhancing the levitation capability of saal and realizing the containerless solidification of those materials with low melting temperature and high density
本文針對當前單軸式聲懸浮能力較弱，而且主要應用於低密度材料無容器處理的研究現狀，以提高聲懸浮能力、實現低熔點高密度材料的聲懸浮無容器凝固為主線，採用理論和實驗相結合的方法，對單軸式聲懸浮過程及其主要影響因素進行了較為系統、深入的研究，主要取得以下幾方面的研究結果。
