Embedded systems are usually diskless systems. In order to keep permanent data in the systems, it is a widely adapted strategy to use flash memory disk as its disk system, therefore how to build a flash memory file system is the focus of this thesis in a reasonable embedded system.

嵌入式系统通常是无磁盘系统，为了让嵌入式系统能够永久性保存资料，使用Flash 存储器是一种普遍的策略，那么如何在嵌入式系统环境中建立Flash 存储器文件系统就成为了本文研究和解决的重要问题。

即不管负载的无功功率如何变化，总要使二者之和为常数，这个常数等于电容器组发出的容性无功功率的数值，使取自电网的无功功率为常数或为0，即：=常数（或0），最终使得电网的功率因数保持在设定值，电压几乎不波动，从而达到无功补偿的目的，以抑制负载波动所造成的系统电压波动和闪变。

For this purpose, the minimum modulus eigenvalue of power flow Jacobian matrix of AC/DC power system is researched; by means of the sensitivity index of nodal voltage to reactive power variation and combining with participating factor, the bus or region where the voltage instability could happen most possibly are judged to provide decision-making foundation for the configuration of reactive power compensation device in power system.

该方法研究了交直流系统潮流方程雅可比矩阵的最小模特征值，以节点电压对无功功率变化的灵敏度为指标，结合参与因子，判断全电网中最有可能发生电压不稳定的节点或者区域，从而为系统无功功率补偿装置的配置提供决策依据。

The analysis results show that PAPF is effective for parallel resonance damping, but can not damp series resonance when capacitor current is not included in the detecting current. And when capacitor current is included in the detecting current, PAPF is prone to be unstable and can not damp parallel and series resonance.

分析表明，由于无功补偿电容器的影响，传统控制策略下的PAPF对系统谐振的抑制效果不理想，同时当检测的负载电流中包括无功补偿电容器电流时，系统还有可能出现不稳定的现象。

The dimensions system is converted into unidirectional draft,and then we take a new algorithm based on the intelligent route search technique by ransack the abut-matrix of the dimension system to inspect if there are dimensions closures or not in the engineering graphics.

将尺寸标注系统转换成无向图的形式，然后采用一种智能路径搜索的算法，对无向图所对应的邻接矩阵进行遍历，完成对整个标注系统中的所有尺寸标注搜索的过程。

Scum and surfactant were also observed accumulated in system because lack of skimmer in the experiment equipment.

还观察到系统产生漂泥和表面活性剂在系统内积累的现象，指出表面活性剂积累是系统无撇渣装置所致。

The tailless aircraft is regarded as one of the developing directions of the new type aircrafts.

无尾飞机是新型飞机的发展方向，与传统的飞机相比，其飞行控制系统更为复杂，故障出现的概率也更大，因此重构控制系统是无尾飞机安全飞行的保障。

In this study, we discussed the phylogenetic relationships in the Anura groups with the sequences of the 12 proteins encoded in the H-strand and 22 tRNAs of mtDNA from 21 species from GenBank. They all indicated that Anura were divided into the Archaeobatrachia and the Neobatrachia,these results supported the monophyletic origin of Anura.

结合饰纹姬蛙和金线蛙的mtDNA以及GenBank上公布的共21种无尾目的线粒体基因组，本文基于编码重链12个蛋白质的基因和编码22个tRNA的基因分别构建了MP系统树，分析了21种无尾目动物的亲缘关系，结果都显示将无尾目分为两大群，支持无尾目的单系起源。
