查询词典 inextensible

The concept that each strand was represented by a Super-Helix was presented to solve the nonlinear behavior of hair strands with respect to bending and twisting, based on the Kirchhoff equations for dynamic, inextensible elastic rods.

基于动态的、不可伸展弹性杆的基尔霍夫方程，提出采用超螺旋线表示头发股来解决头发股的弯曲和挠曲的非线性行为。

Inextensible steel reinforcements are either flat ribbed strips or welded wire mats, both of which are hot dip galvanized (except for temporary structures).

不可拉伸的钢筋可以是平的钢筋条，也可以是焊接钢筋网，均经过高温镀锌。

The transfer matrix method is used to carry out the vibration characteristic analysis of the fluid-filled piping system. The transfer matrix of the axial, transversal and torsion vibration of the fluid-filled straight pipe element is presented. And the transfer matrix of the elbow is derived according to the discrete model of the inextensible theory of the curve pipe. The effect of the flexural factor on the elbow's transfer matrix is studied.

基于充液直管的梁模型，考虑液体与管道之间的泊松耦合，详细推导了充液直管单元的轴向、横向及扭转振动传递矩阵；采用弯管不延伸理论的离散模型，将变管离散为一组首尾相连，并成一定角度的短直管单元，通过建立弯管处力平衡方程与连续性方程，建立了弯管平面内振动的传递矩阵，并研究了弯曲因子对传递矩阵的影响。

As the tube is the arc horn tube with irregular section and inextensible special-shaped pieces, and white lines and red lines are not allowed in the groove at the back, the film paste can only be done by manual work and the location of sing by human observation

因管为不规则截面的弧形喇叭管，为非可展开的异型件，且背面凹槽处不得有白线和红线，菲林的粘贴只能用人工完成；标志的位置只能人工观察
