than 2.2, the electromagnetic pressure acting on melt can be simply expressed as Pm =B^2/wμ, and the melt shape would be known only by measuring the distribution of magnetic flux density. As a is small and makes the ratio a/8 less than 2.2, the melt shape and electromagnetic pressure for confining and shaping are determined not only by magnetic flux density B but also by melt thickness a, electromagnetic parameter μγ and current frequency f. In this paper, an equation used to calculate electromagnetic pressure acting on 'thin plate-form melt' is brought forward. The equation gives a precise relationship between electromagnetic pressure factor p and melt thickness a, electromagnetic parameter μγ and current frequency f.

Many domains, including communication, signal processing, and image processing, use the Fourier Transform as a mathematical tool for signal analysis. Although it can analyze signals with steady and transitory properties, it has limits. The Wavelet Packet Decomposition (WPD) is a novel technique that we suggest in this study as a way to improve the Fourier Transform and get beyond these drawbacks. In this experiment, we specifically considered the utilization of Daubechies level 4 for the wavelet transformation. The choice of Daubechies level 4 was motivated by several reasons. Daubechies wavelets are known for their compact support, orthogonality, and good time-frequency localization. By choosing Daubechies level 4, we aimed to strike a balance between preserving important transient information and avoiding excessive noise or oversmoothing in the transformed signal. Then we compared the outcomes of our suggested approach to the conventional Fourier Transform using a non-stationary signal. The findings demonstrated that the suggested method offered a more accurate representation of non-stationary and transient signals in the frequency domain. Our method precisely showed a 12% reduction in MSE and a 3% rise in PSNR for the standard Fourier transform, as well as a 35% decrease in MSE and an 8% increase in PSNR for voice signals when compared to the traditional wavelet packet decomposition method.

目的:考察母亲与青少年居家身体活动的代际传递效应,以及亲子沟通、家庭亲密度在此效应的增值贡献。方法:采用国际体力活动量表(短版)、家庭沟通模式量表、家庭亲密度量表(学生版),对1849名初中生及其母亲进行调查。结果:母亲的居家身体活动、亲子沟通和青少年的居家身体活动在青少年性别、年级的差异皆不显著;青少年感知家庭亲密度的性别差异不显著,但年级差异显著,6~8年级青少年的家庭亲密度随年级升高而递减;母亲居家身体活动能显著预测青少年居家身体活动,且在母亲居家身体活动与青少年居家身体活动的影响链上,母亲的亲子沟通、青少年感知的家庭亲密度具备链式中介效应。结论:对于不同性别青少年,母亲居家身体活动、亲子沟通、青少年居家身体活动、家庭亲密度具有一致性特征;对于不同年级青少年,母亲居家身体活动、亲子沟通和青少年居家身体活动具有一致性特征,而家庭亲密度随着年级升高而逐渐降低;母亲与子女居家身体活动存在代际传递效应,且母亲的亲子沟通、青少年感知的家庭亲密度在该代际效应中发挥重要的增值贡献。
