A lot of friends seek a term with the index, the word is done, rank also the first, but discovering the discharge that comes from this word however is not with the index same, contrary they are to have very big discrepancy, may be sometimes a few be the difference of about a hundred times even?

很多朋友用指数去找词，词做上来了，排名也第一了，但是却发现来从这个词来的流量并不是和指数的一样，相反他们是有很大出入的，有时可能是几十甚至是上百倍的差距？

However, there is little discussion on reliability evaluation of nonworking redundant systems such as cold and warm stand-by systems in literature, especially there is no discussion in case of medium and small sample size.

本文结合总装备部九五预研重点课题《小子样系统可靠性综合方法研究》和我国工程实际，较系统地研究了常见各种贮备系统的可靠性评估问题，包括冷备和温备两种贮备类型，指数型和Weibull型两类部件，完全可靠、成败型和指数型三种开关，以及定数、定时、和定总时截尾三种指数型试验数据。对上述各种常见情况下的贮备系统，分别给出系统可靠度函数及其点估计，并用WCF方法导出了可靠度置信下限。

Based on the relationship between matrix and symmetric matrix global exponential stability of the discrete-time neural networks model and the result of exponential convergence rate were obtained by using the characteristics of eigenvalues of a positive definite matrix and introducing a proper factor.

针对带有边界约束的凸二次规划问题，利用离散神经网络模型的建模原理，构造了一个神经网络模型。利用矩阵与对称矩阵的关系和正定矩阵特征值的性质，通过引入一个适当的因子，得到了该离散型神经网络模型是全局指数稳定性和指数收敛率的结果。同时分析了该结果的优越性和存在的不足，提出了解决的3种方法，最后给出了实例说明本方法取得结果的实用性

Write a program that prompts the user to input two numbers, the base and exponent. Print the result of raising the base to the power of the exponent.

编写程序，要求用户输入两个数——底数和指数，输出底数的指数次方的结果。

Through the collection and selection of the original data, the establishment of comprehensive assessment index regime and the determination of index weight, this thesis establishes a canonical and exercisable quality index system of construction projects.

通过原始数据的分析整理、综合评价指标体系的确定、各级指标的赋权以及建筑工程质量指数计算方法的选择和指数分析模型的建立，本文构建了较为规范的建筑工程质量指数体系。

The changes of partitioning ratio index for unit organ could be described by exponential equation and quadratic equation with different stem internode,leaf,petiole,and cotton bud and boll according to different internode positions on main stem and sympodial stem.

模型采用线性和指数方程描述了叶片、叶柄、主茎、分枝及蕾铃单位器官分配比例指数随GDD的动态变化过程；分别用指数方程及一元二次方程描述了叶片、叶柄、主茎、分枝及蕾铃单位分配比例指数随不同叶位、节位的动态变化过程。

The second one: we studied the effect of temperature on performance of LDs. It was found that threshold current increase exponentially, outpower and slope efficiency decrease parabola and exponentially respectively. Coefficient of temperature shift is 0.24/K, whereas characteristic temperature also decrease with rise of temperature.

研究了温度对激光器各参数的影响，随着温度的增加，阈值电流呈指数增加，输出功率和斜率效率分别呈抛物线和指数关系递减，同时特征温度也减少，波长随温度的漂移系数为0.24nm/°C，并且总结了一些温度和结构设计方面的关系。3。

For example, when you need to input floating-point numbers in exponential notation you should allow the user enter not only digits but also a decimal separator and an exponent symbol.

例如，当您需要输入漂浮在指数表示浮点你应该允许用户进入，不仅数字，而且一小数点和指数符号。

In the appropriate place and an optional "e" suffix representing scientific notation.

在e和指数之间可以用+表示正指数－表示负指数。
