Smaller log records mean more records for same sized logs, how random were data modifications (random updates will need random IO to check if pages are up to date), number of unflushed pages in innodb buffer pool and its size as well as performance of IO subsystem.

日志记录的值越小意味着同样大小的日志里可以存储更多的记录，随机数据修改的几率有多高(随机更新需要有更多的随机IO来检查内存页是否更新)，innodb 缓冲池中未被刷新的内存页数量并且它也是IO子系统的性能表现。

日志记载的值越小意味着同样大小的日志里可以存储更多的记载，随机数据修正的几率有多高(随机更新需要有更多的随机IO来反省内存页是否更新)，innodb 缓冲池中未被刷新的内存页数量并且它也是IO子系统的性能表现。

The article first theoretically analyzes the principle that microcavity reduces threshold 、changes resonant modes of output light and enhances unidirection of the random laser.Then study the structure parameters of different microcavity by transfer matrix.Based on the theory of Maxwell equations and the rate equations, analyze the principle that microcavity reduces the threshold by FDTD method: Changing the confined position,reducing relaxation time and increasing reversing particles, also simultaneously study the influences of the threshold and output light modes by different microcavities and random intensity of random medium.

首先从理论上分析了利用微腔降低随机激光器阈值、改变出射光振荡模式、提高出射光准直性的原理，然后利用传输矩阵法模拟研究了不同的微腔应具有的结构参数，最后以麦克斯韦方程和速率方程理论为基础，利用时域有限差分法分析了利用微腔降低阈值的原理：改变局域化位置、缩短弛豫时间及增大粒子数反转，同时也模拟研究了微腔、随机介质的随机强度对阈值及出射光波模式的影响。

Our results provide nonparametric evidence of unspanned stochastic volatility and suggest that the unspanned factors could be partly driven by activities in the mortgage markets.

A new method is suggested to solve the problem of nonstationary random responses of elastic-viscoelastic composite structures. The correlation characteristics of responses under uniformly modulated or ununiformly modulated random excitations are obtained.

提出了演变随机激励下弹性-粘弹性复合结构非平稳随机响应特性的一种分析方法，分别讨论了均匀调制和非均匀调制两种情况下粘弹复合结构系统随机响应的相关特性。

It is found that under certain conditions stochastic bifurcation mostly occurs when a stochastic attractor collides with a stochastic saddle.

揭示了随机分岔的发生主要是由于系统的随机吸引子与系统的随机鞍碰撞产生的。

Besides, a method has been creatively proposed to process stratum rupture using cross-ring. Bridge-edge and stratum area decompounding method has been used to solve reverse fault issue, and the applying problem basing on state machine model has been resolved by using a function class mechanism. It supplies a new idea and new method for reservoir stochastic modeling. At the same time, the geology stochastic modeling theory system has been enriched and improved. It has important academic and practical meaning in deepening reservoir development geology stochastic modeling theory and increasing remaining oil research extent.
