| 1. | Just this fact was one of the motivations for the discussion of boundary approximations in chapter 4 . 恰好这个事实是第四章讨论的边界近似式的引伸之一。 |
| 2. | These formulas make the approximations for the derivatives at these points in a nonsymmetrical manner . 这些公式使得这些点子上的导数近似式是非对称形式。 |
| 3. | For any approximation to be valid it must provide a result that is in some sense close to the solution of the original problem . 任何有效的近似式必须在某种意义上提供一个接近于原问题解的结果。 |
| 4. | We find that there are reasonable approximations to all three modes, but the application of all such approximations must be made with caution . 我们发现,三种模态都有适当的近似式,但应用它们必须谨慎。 |
| 5. | Manipulation of the pure time delay in digital control system applying pade approximation 近似式处理数字控制系统中的纯滞后 |
| 6. | In terms of accuracy , the present approximation is superior to the previously reported ones 就准确度而言,本研究所推导之近似式优于其他文献中所发表之相关公式。 |
| 7. | Excellent agreement between the present approximation and the exact solution was found over the entire time domain 在整个时间范围内近似式运算结果和准确解均十分吻合。 |
| 8. | Intra particle adsorption , diffusion and a first - order reaction occurring within the porous particle are considered in the present formula 近似式所考虑之现象包括颗粒内之吸附、扩散及一次反应。 |
| 9. | After coordinate transformation , we can get the approximate confidence region of parameters in virtue of the approximate expression of e 然后利用坐标变换,借助e ~ x的近似式,用数值方法求解获得参数的近似置信域。 |
