查询词典 exponential equation

The process of random load action was described with the Poisson stochastic process and the time de pendent reliability models of series system, parallel system and k/n system were developed with the probability differential equation and total probability formula when strength degenerated as time, Taking the degeneration of strength following the exponential rule as an example, the relationships between the reliability and failure rate of system and time were studied.

采用泊松随机过程来描述载荷的作用过程，运用概率微分方程和全概率公式建立了强度随时间退化时的串联系统、并联系统以及k/n系统动态可靠性模型。以强度退化服从指数退化规律为例，研究了串联系统、并联系统以及k/n系统的可靠度和失效率随时间的变化规律。

For exponential distribution, the acquired estimate expression is the same as the result obtained by other method in reference [8]; for Weibull distribution, the author prove that γ satisfies a non-linear equation and λ is afunction of y; for lognormal distribution, a iterative algorithm for parameter estimation is proposed, which is the expansion of some results in Wolynetzs Ph.D. thesis.

对指数分布，得到的估计表达式与文献[8]中使用其他方法得到的结果相同；对Weibull分布，论文证明了参数γ满足一个非线性方程，而λ则可以直接由含有γ的表达式求出；对对数正态分布，论文给出参数估计的迭代算法，这可以看成是Wolynetz博士论文结果的推广。

Of many steady testing work that have been done at Shunan gas reservoir in Maliuchang gas field, data process are respectively conducted by traditional multi-point binominal or exponential process data and one point method for deliverability equation.

在蜀南气矿麻柳场气田进行了大量的稳定试井工作，分别用传统的多点法二项式、指数式处理资料，以及用&一点法&产能公式进行资料处理，发现两者求出的气井绝对无阻流量偏差达到30%-90%，甚至更高。

By introducing a parameter b and using the extended tanh method , the rational hyperbolic functions method and the rational exponential functions method,We extend the solutions of a class of wave equation.
