设计法

• But to this day , the design of the wind turbine is still the experience method because of complex computation and device . this method is blind and uncertain
  但是到目前为止，由于计算过于繁琐，模型试验设备过于复杂，风力发电机的设计基本上还是采用经验设计法，带有很大的盲目性和不确定性。
• This paper ' s main content is the study of short carbon fiber utilized in hpc . designed the experiments with confecting technique , and studied the dispersing technology of carbon fiber into the hpc
  本文研究了低掺量短碳纤维在hpc中的应用。运用均匀设计法设计实验，对碳纤维的分散工艺进行了有效研究。
• Methods : using orthogonal design method , to apply extract yield of rhizoma coptis and the extract amount of berberine hydrochloride as observing indexes , to measure the content of dl - tetrahydropalmatine with hplc
  方法：采用正交设计法，以槲皮素、原儿茶醛薄层斑点，延胡索乙素含量为指标，优选提取工艺。
• In slope control engineering design , still adopt routine definite value design method at present , which regard design parameter as definite value , has neglected their randomness and variability
  在边坡治理工程设计中，目前仍采用常规定值设计法，把设计参数当作定值来处理，忽略了它们的随机性与变异性。
• The experiment of reinforcing wall of stope with cable - anchors has proven that stability graphical method is practicable , in which the determined cable - anchor supporting parameters and stress analysis are rational fairly
  采场帮壁锚索加固试验证明，稳定性图解设计法是切合实际的，确定的锚索参数及受力分析是比较合理的。
• Traditional engine design method is experience design method , since 1980s , many modern design methods , which are limited in the static design category , have been taken
  传统的发动机设计方法是经验设计法，八十年代以来采用了许多现代设计方法，但大都局限于静态设计的范畴，对于日趋严酷的设计指标，静态设计已难以满足要求。
• We discussed the method of state space design , and deduced the ackermann formulation . in the end , separation theory is adapted to the discrete system of the delta domain
  文中讨论了delta域内的状态空间设计法：极点配置设计法及状态观测器设计法，推导了delta域内的ackermann公式，得出了分离定理同样适用于delta域内的离散系统。
• The traditional design method of propellers is calculating the surface of propeller from table of offsets , which is low - precision and time - consuming . the dynamic flow performance could n ' t be forecasted by this method
  传统搅拌桨设计都仿照船用推进螺旋桨的图谱设计法，查表计算，精度低、周期长，且无法预测桨的流体动力性能。
