常数函数

The main difficulties are to find the functions which achieve the best constant of critical Sobolev-Hardy imbedding and to overcome the singularity of the positive solutions.

这里的主要困难是要找到Sobolev-Hardy临界时最佳嵌入常数的达到函数，同时在寻找变号解时还要克服方程正解的奇性。

Many traditional compiler optimizations fall into this category: copy and constant propagation, redundant expression elimination, dead code elimination, peephole optimizations, function inlining, tail recursion elimination and so forth.

许多种传统的编译器优化方式都可以归结于这两种方法，比如说：copy and constant propagation（用常数取代程序中不变化的变量），冗余表达式消去，死代码消去，Peephole优化，Inline函数，尾部递归消去（展开在程序尾部的递归，减少堆栈消耗

Suppose that and are integrable on and is a constant .

设函数和在上都可积，是常数，则和+都可积，并且

By using the approach of weight function, a new Hilbert-type integral inequality with some parameters and a best constant factor is given. The reverse form and the equivalent forms are also considered.

应用权函数的方法，建立一个新的含多个参量的具有最佳常数因子的Hilbert型积分不等式，并考虑了它的逆向形式及相应的等价形式。

These comparison show that all calculation results, such as dissociation energy, equilibrium internuclear distance and rotation-vibration constants, are better agreement with experimental results than other theoretical ones.

结果表明，无论是离解能、平衡核间距还是分子的振转常数，利用九参数Murrell-Sorbie势能函数得到的结果与实验结果相比较，都明显好于其他理论结果。

In the second part, we study the attractor of Iterated Function Systems on Rd with non-constant contractive ratios, which generalizes the classical result.

在第二部分我们研究Rd上的迭代函数系的不变集，特别我们考虑了压缩系数不是常数的情形，所得结果给出了经典结果的一个非平凡推广。

In fact, the total energies for the possible metastable alloy phases of A〓B and AB〓 types of six possible structures were calculated as a function of their lattice constant to find out if the respective metastable phases of A〓B or AB〓 types could be relatively stable in the selected systems. The calculation not only predicted the possible metastable states but also the lattice constant of the corresponding metastable alloy phases of either FCC or HCP structures.

对可能存在的A〓B或AB〓型亚稳合金相的六种结构，将总能量作为点阵常数的函数进行了计算，用以找到选定系统中相对稳定的A〓B或AB〓型亚稳合金相。

C51 microcontroller help develop procedures, C51 library contains several subroutine, functions and constant definitions.

帮助开发C51单片机程序，C51程序库包含多个子程序、函数和常数定义。

As we know, many results on analytic solutions of iterative equations are obtained by constructing a majorant series. For technical reasons, in previous works an indeterminate constant α, as the eigenvalue of the linearization of unknown function at its fixed point, is required to be off the unit circle or lie on the circle with the Diophantine condition.

已有的许多关于迭代方程的解析解结果都是运用优级数法得到的，并要求一个作为未知函数在其不动点处的线性部分的特征值的常数α不在单位圆周上或者α在单位圆周上但满足Diophantine条件。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
