一阶误差 [yī jiē wù chā]
first-order error
- 摘要基于一阶线性误差假设推导了空间机器人末端操作器运动学位姿误差模型。
On the basis of hypothesis of first ordered linear error this paper derived the kinematics posture error model of end operator. - 本文利用正规格林函数及对偶论证技术证明了一类强非线性二阶椭圆问题混合元方法对函数的L2投影具有几乎超收敛一阶的最大模误差估计，对伴随向量函数具有拟最优最大模误差估计.
Using the regularized Greens functions and a duality argument, it is proved that the mixed finite element method proposed in this paper possesses the superconvergence by almost one order maximum norm estimates for the L2－projection of the function and quasi-optimal maximum norm estimates for the associated vector function for a strongly nonlinear second order elliptic problem. - 对有限元计算值与实测值进行比较，四种约束模态下一阶固有频率有限元计算值的误差均小于15%，符合工程许可范围。
Experiments for the natural frequencies of low-finned tube were made in above-described constraint mode.
