1) block horn
立方形焊头
1.
A new design method for large cross-section ultrasonic plastic welding block horns with slots was presented and experimental validation on it was carried out.
首先通过合理开槽将大尺寸立方形焊头划分为若干单元,然后将各焊头单元和立方形半波振子比较,利用等效机械阻抗的概念得出焊头单元的频率方程,其间考虑了耦合振动的影响。
2) blade-like horn
长方形焊头
3) strip-like horn
条形焊头
1.
In this paper,the strip-like horn is separated into several equal portions,and each portion can be viewed as a compound stepped type horn,and its fre-quency equation is derived by the transmission matrix method.
将长条形焊头通过合理开槽划分为若干相等的单元,每个单元可作为复合阶梯形变幅杆来处理,用传递矩阵法得出了焊头单元的频率方程,为长条形开槽焊头的设计提供了理论依据。
4) jump weld
T形焊接头
5) pseudocube
准立方形
1.
Submicron spindle and pseudocube α-Fe2O3 particles were synthesized at pH=6～9 in the presence of trace Na2SiO3.
以Ferrihydrite(又称水合氧化铁hydrous iron oxide)为反应前驱物,Fe(II)为催化剂,在微量Na2SiO3存在下,控制pH=6～9范围内合成出了亚微米级纺锤形和准立方形α-Fe2O3微粒。
6) cubic-crystal
立方晶形
补充资料：立方
①指数是3的乘方，如a3(a×a×a)，43(4×4×4)。②立方体的简称。③指立方米。
