The examples testify that the collocation method has the advantages of less calculation quantities and accurate results.

且矢高f较大的情况下也能获得较好的收敛效果。

The rules include not only the complete procedures to construct the three-powered interpolation used by Shoushi Computus in calculating the solar, lunar and planetary equations of center, but also the detailed routines, namely the Geyuan Shu (the procedure of circle division), to derive the table contained in the Shoushi Computus for transferring the pseudo-ecliptic longitudes of the sun into equatorial coordinates, which turns out to be compatible with the results obtained with spherical trigonometry.

从总体角度来看，他在《授时历》立法原理方面的工作已经超过了嘉靖年间顾应祥和周述学等学者的工作，不过，在弧矢割圆术中应用的高次方程解法方面，邢云路的工作则可能直接受到了顾应祥、周述学等学者相关工作的影响，而且邢云路在高次方程解法方面也没有超出明代历算家对高次方程数值解法的认识水平。

Before discussing Xing Yunlu's calendrical work, we reviewed the calendrical system of the Ming Dynasty and the status of the calendar crisis and the endeavor of reviving the traditional calendar made by the scholars Gu Yingxiang (1483-1565), Tang Shunzhi (1507-1560) and Zhou Shuxue (?1500-?1572) during the Emperor Jia Jing (1522-1566) in the Ming Dynasty. These scholars had paid attention to the underlying mathematical principles of Shoushi Computus, especially the method on arc and arrow in the geometry.

在讨论邢云路的改历活动之前，首先对明代的历法系统以及传统历法出现危机的状况以及明代嘉靖年间顾应祥(1483-1565)、唐顺之(1507-1560)、周述学(约1500-约1572)等复兴传统历法的努力进行讨论，指出：明代嘉靖年间学者的改历理念主要是注重讨论被钦天监历官忽视的《授时历》的立法原理问题，并对《授时历》弧矢术做了一些有益的探求工作。

AIM To test both normal adult ferrets and mature animals whose pinna and concha had been removed bilaterally in infancy for their ability to localize sound relatively in the horizontal plane and midsagittal plane.

目的 测试比较正常成年和无耳廓成年雪貂在水平面和正中矢状平面内对声音的定位能力。

Methods\ The size and shape of conchae, nasal meatuses and the structures of the lateral wall in middle nasal meatus were observed and measured on 67 sides of the sagittal head specimens and the distances from anterior nasal spine to other anatomic parts were also measured.

方法选用67侧正中矢状切的头部标本，观测各鼻甲、鼻道及中鼻道外侧壁结构的形态和大小，并测量前鼻棘至各解剖部位的距离。

Mathematical model has been dealt with by punish function search method. Hooke-Jeeves modular vector search method and Powell conjugate direction search method have been adopted and modified.

利用"惩罚函数"法进行了数学模型的处理，采用并改进了Hooke-Jeeves的模矢搜索法及Powell的共轭方向法，还提出一种随机搜索法。

This paper presents a hybrid algorithm which combines thepattern search method and the genetic algorithm for bound constrained optimization.

本文构造了一个基于模矢搜索和遗传算法的混合优化算法。

Degree B-Spline curve is chosen to fit the longitudinal settlement curves, which solves the problem of curvature continuum for joint notes due to its continuous second derivative vector and overcomes the efficiency and accuracy of computing curvature with 3 points by hand.

选取三次B样条方法对隧道纵向累计沉降曲线进行拟合，利用三次B样条曲线二阶导矢连续的特性，解决了拟合曲线在曲线连接点处曲率的连续性问题，克服了以往人工计算隧道曲率半径在效率和准确性方面的缺陷；并在此基础上，推导了隧道纵向变形曲率与纵向螺栓拉应力、相对弯曲与纵向螺栓剪应力之间的关系； 3。

Those images boasted bronzed children racing joyfully down a bank of emerald green grass towards a vast expanse of water so blue that the cornflower sky above looked dazzled.

在照片里，晒得黝黑的孩子欢快地沿着长满翠绿色青草的湖岸追逐，一直跑到一片开阔的湖水，蓝色的湖水使头顶上矢车草色的天空显得是那么耀眼。

For out in the ocean,where the water is as blue as the prettiest cornflower,and as clear as crystal,it is very ,very deep;indeed,that no cable could fathom it:many church steeples,piled one upon another,would not reach from the ground beneath to the surface of the water above.

在深深的大海的尽头，那里的海水蓝的就象最美丽的矢车菊花，清澈绚丽就象水晶一样迷人，它是那么那么的深，真的，任何锚索都接触到不到他，就算好多的教堂尖塔都堆起来也不能从地上到了海面。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
