钢琴调律手法的力学分析

从物理学的角度,通过公式,详细分析了钢琴弦轴的张力、调弦时扳柄方位的最佳角度等问题。

科学采用钢琴调律手法

钢琴调律工作在音乐学习、音乐创作和音乐实践中起着很重要的作用。经常在音律准确的钢琴上弹奏，才能使人特别是孩子建立起正确的音高概念、逐渐形成良好的乐感。音乐家们在音律准确的钢琴上，才能创作和演奏出优美动人的音乐。在音律不准的钢琴上弹奏出的乐曲。

论钢琴调律的方法

本文叙述了钢琴调律的方法、步骤、钢琴调律的手法以及如何正确的使用钢琴调律扳手。

钢琴调律艺术刍议程德祥

随着钢琴乐器和钢琴教学的日益普及，钢琴的护理和保养也被众多人士所关注。但是，由于人们对钢琴、钢琴护理和保养的认识不够深入，导致许多钢琴的拥有者甚至于部分从事音乐工作的人员对钢琴调律护理认识不足，从而不能够对这件昂贵的乐器进行正确合理的维护，使其发挥最佳的性能与状态。鉴于此，我们有必要从钢琴调律的艺术内涵、钢琴调律的重要性、钢琴调律的周期和常用手法及钢琴调律的技术细节等几个方面来探讨钢琴定期调律，进而实现正确的钢琴护理与保养。

浅谈钢琴调律技术及音准的稳定性

钢琴的音律标准与否影响着人们对音乐的学习和创作热情。想要将钢琴的音律达到一个标准、理想的程度，就需要精准与快捷的调律手法。调律的方法对钢琴调律的结果起着重要作用。如果方法不得当，就会使得钢琴的弦轴以及琴弦有很大的损伤。因此，钢琴调律的方法对钢琴演奏的影响是重大的。本文就以上述的问题为线索，浅谈一下钢琴调律的技术方法及音准的稳定性。

Design of Off-statistics Axial-flow Fans by Means of Vortex Law Optimization

Off-statistics input data sets are common in axial-flow fans design and may easily result in some violation of the requirements of a good aerodynamic blade design.In order to circumvent this problem,in the present paper,a solution to the radial equilibrium equation is found which minimizes the outlet kinetic energy and fulfills the aerodynamic constraints,thus ensuring that the resulting blade has acceptable aerodynamic performance.The presented method is based on the optimization of a three-parameters vortex law and of the meridional channel size.The aerodynamic quantities to be employed as constraints are individuated and their suitable ranges of variation are proposed.The method is validated by means of a design with critical input data values and CFD analysis.Then,by means of systematic computations with different input data sets,some correlations and charts are obtained which are analogous to classic correlations based on statistical investigations on existing machines.Such new correlations help size a fan of given characteristics as well as study the feasibility of a given design.
