That is, direct search methods for unconstrained optimization depend on the objective function only through the relative ranks of a countable set of function values.

那就是说，无约束优化的直接搜索法仅仅依赖于通过可数集的函数值的相关阶的目标函数。

In the last part of this paper, some numeral test functions were calculated by the software to test the efficiency of the algorithms included, then a reentry vehicle with cruciform flaps were taken as examples to testify the utility of Multi-Objective Optimization Algorithm Library.

在本文的最后，先用几个数值测试函数对方法库中几个产生式算法的性能进行了验证，然后用方法库对带控制舵再入飞行器进行了气动布局和外形优化。

Programming with VB Numerical Analysis of cubic spline interpolation function.

详细说明：用VB程序编写的数值分析三次样条插值函数。

Firstly, the relation between cumulative distribution function and aggregate size are available based on stereological theory.

首先，根据体视学原理，得到了骨料累计分布函数与粒径之间的关系，利用Fortran语言编制程序，计算出骨料的粒径和位置，模拟了混凝土二维圆形骨料的随机分布，随后根据材料的细观结构，建立起了混凝土的数值模型。

These spacings are valueswithin the interval[0,1]such that the inverse of cumulative distribution function atlarge sample quantiles is equal to the value of spacings.

这些线性估计依赖于被选择的顺序统计量，而顺序统计量的秩由一些间隔所确定，这些间隔是大样本分位数依分布函数的反函数在区间[0，1]上确定的数值。

Furthermore, a Maple program is designed to verify the validity of the autocorrelation.(2). Based on Whiteman\'s generalized cyclotomy, new binary generalized cyclotomic sequences of order 2~k and length pq are constructed.

构造了一类平衡的新的六次剩余序列，分别利用多项式分解理论和迹函数表示确定了该类序列的线性复杂度和极小多项式，给出了序列的自相关函数值并编制Maple程序验证该结果的正确性，讨论了序列的稳定性。

The yield increased as the ecapotranspiration,while it comes to a certain,the yield won't increase,it may decline. 2According to the non-full irrigation experimental datum of spring wheat and flax in Liangzhou and Gulang city of Shiyang River Basin,calculating the crop water deficiency sensitive index or coefficient by using crop water production function models of Jensen,Blank,Stewart and Minhas.

产量随着耗水量的增加而增加，当达到一定数值将不再增加，反而有下降的趋势。2 依据石羊河流域凉州和古浪春小麦和亚麻非充分灌溉试验资料，利用现有的Jensen 、Blank、Stewart 和Minhas 水分生产函数模型求解作物的缺水敏感指数。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
