    本文应用能量原理和阻尼分析的方法解决了平纹织物复合材料的复杂结构损耗因子的计算问题。
  2. A Research into Synthesized Curve of Free Curve and Sine Curve
    自由曲线与正弦曲线合成曲线的研究
  3. In this paper we prove that the global attractor for the Sine-Gordon system without capacitance effect under Neumann boundary condition is an invariant curve. The behavior of the system on the curve is like the orientation preserving homeomorphism on a circle.
    证明当扩散系数适当大时Neumann边条件下无电容效应的SineGordon系统全局吸引子是一条不变曲线,系统在其上的行为类似于圆周上的保向同胚。
  4. A curve of sine approximate error in angle measure is devised, a mathematical model of the measurement error is presented.
    作出了角度测量中正弦近似误差特性曲线,并提出了该测量误差的数学模型;
  5. By adopting patented hydraulic valve train system to drive valves with hydraulic pressure in stead of cam, valve lift curve becomes rectangle instead of sine wave, which improves air charge volume efficiency significantly.
    通过专利技术发明的液压配气技术来驱动气门,就不受凸轮形状的限制,气门的开启曲线从正弦波变为矩形波,使内燃机的充气系数得到极大提高。
