求值

Firstly, the key frames are created by the methods of inverse kinematics. Then, the internal key frames are computed by the interpolation of spline curve and spherical linear.

首先使用逆运动学方法求出关键状态，然后使用样条插值和四元数球状线性插值方法计算中间状态，完成跑步的过程。

On the one hand, the linear interpolation in plane makes it easy to separate the three-dimensional null subspace corresponding to rigid body motions, hence what is left to do is just to compute the inverse of a symmetric definite submatrix numerically.

在物理坐标系中的线性插值函数便于将三个刚体模式分离出来，从而只需计算对称正定子阵的逆，避免了求广义逆的数值困难；在参考坐标系中的高阶插值函数则可保持原平面弹性单元的列式方式。

Though the fuzzily synthetic step by step, the total risk degree of the Ecological system and the risk degrees of risk factors of each periods

然后，根据上述方法，求出不同开发规模下生态系统一个生命周期的生态总风险值和各个阶段风险因素的风险值。

But the data analysis is relied on experience and statistics in a certain extent, so sometimes it makes big errors. Daniudi gas field is a low permeable gas field, the pressure buildup slowly. The measured formation static pressure is low and the flow pressure is high, so the calculated unresisted flow is high.

特别是大牛地气田属于低渗透气藏，压力恢复缓慢，所测的地层静压值偏低，求产开井3天以上多数井测取不到稳定的流压，所取流压值偏高，计算的无阻流量均偏高。

We obtain the eigenfunction through inverse transform,and select appropriate threshold to extract iso-surface.We append the weighted coefficients on sampling density for non-uniform sampling to further compute rational thresholds.

调用快速傅立叶变换FFTW(The Fastest Fourier Transform in the West)软件包，根据点的位置和法向量计算傅立叶系数，通过逆变换求出特征函数，选择合适的阈值提取表面的等值面，对于非均匀采样通过采样密度的加权系数进一步计算合理的阈值。

In section 3, on the base of the iterative algorithm, we obtain a new iterative algorithm which is convergent to the signal faster than the old one. In section four, if the form of φ is simple and the sampling set is the integer set Z, then a direct reconstruction formula is presented.

在第二节，我们通过计算对偶框架来重建信号，这与传统的计算对偶框架方法不一样，该算法是通过计算一个矩阵的逆矩阵来计算对偶框架，当矩阵是奇异矩阵时，可通过奇异值分解方法或截断奇异值分解算法来求矩阵的广义逆矩阵。

The numerical experiment results show that the imaging convergent speed of the direct demodulation imaging method is accelerated dramatically using the ways proposed in the present paper.Furthermore, the author proposes one way to improve timing performance of parallel interpolative algebraic reconstruction.

此外初步研究了平行束的插值代数重建算法，在求像素投影地址时利用像素与像素投影之间的相关性和图像区域的对称性来提高插值代数重建算法重建图像的速度。

By usingthe dynamica l programming method, the optima l investment portfolio andconsumption policies for one kind of typica l utility function case areobtained,then we make numerica l simulation for it and get the numerica lsolution.

然后运用动态规划方法，对于一类特殊的效用函数情形，求出了最优投资组合及消费选择的显性解，并进行数值试验，得出了值函数的近似解，最后将值函数的解析解和数值解进行比较，得到了相对误差示意图。

In pressure of influence underbalanced drilling,such as drilling fluid column pressure,annulus pressure,underbalance pressure,wellhead back pressure and formation pressure etc.,the formation pressure is basic pressure.Because all pressure calculations are built on the basic pressure.

认为在影响欠平衡钻井的钻井液静液柱压力、环空压耗、欠压值、井口回压、地层压力中，地层压力是首先要搞清楚的最基础的压力，最好先求出地层压力而不必急于进行欠平衡钻进，因为一切欠平衡的压力计算都是建立在这个基础压力之上的；再根据地层压力确定合理的欠压值，确定所用的钻井液密度。

Considering principles of sedimentation geology, utilizing the premise that two sequential layers (eroded and underneath uneroded layers) enjoy approximate deposition speeds, we plot with residual thickness values and thickness values of underneath uneroded layer in cross sections. By analyzing the diagram, we can not only obtain the eroded thickness of strata, but also explain the original sedimental environment of the eroded strata and the later structural erosion causes.

介绍了4种解释模型，充分考虑了沉积地质学原理，利用相邻两层沉积速率相近这个前提条件，通过在纵剖面上对剥蚀层残余厚度及下伏未剥蚀层厚度值进行坐标投点，分析它们的图形分布规律，不仅可以量化求取剥蚀厚度值，还可以对剥蚀层的原始沉积环境及造成剥蚀的后期改造作用，做出重要的地质成因解释。
