The results indicated that the pattern of reserving broad-leaved tree in Chinese fir stand has a flora of 57 families, 102 generas and 138 species more than that of pure stand, which is dominated by dicotyledon that occupied 61.4%and 68.6%of total families numbers and total generas numbers, respectively.

双子叶植物在群落植物组成中占优势，分别占总科数和总属数的61.4％和68.6％。

FIR relies on high- temperature and time-spatial resolution digital devices coupled to real-time processing.

FIR必须依靠结合有实时处理器的高温时空分辨率的数字设备。

Experiments showed that the performance of the designed FIR type 25Hz AC counting signalling digital filter can satisfy the particular needs of the cab signals.

通过实验验证了所设计的 FIR 型25Hz 交流计数电码信号数字滤波器的性能可以满足机车信号的特殊要求。

By defining a discriminability function and utilizing some images with synthetic defects, a parameter selection method is proposed to adapt to various fabric types when the Gabor filter bank is applied in defect segmentation. It is argued that only the real part of Gabor filter works during segmentation; the radial orientation can be limited to horizontal and vertical direction; the radial frequency and the length of the FIR filter should depend on the basic frequency of the fabric texture.

本文通过定义分辨力函数，以合成疵点图像为研究对象，提出了在实时应用中对各种不同的纹理图像能快速确定Gabor滤波器组参数的方法：疵点分割中只需用到实Gabor滤波器；方位角只需取水平和垂直方向，径向中心频率和FIR滤波器长度的选取依赖于布面纹理的固有频率。

This time, I remembered I was lying in the oak closet, and I heard distinctly the gusty wind, and the driving of the snow; I heard, also, the fir bough repeat its teasing sound, and ascribed it to the right cause: but it annoyed me so much, that I resolved to silence it, if possible; and, I thought, I rose and endeavoured to unhasp the casement.

这次，我记得，我躺在橡木壁橱里，并且很清晰的听见外面的大风，还有被风吹的雪的声音。我听着，还是，冷杉还是不断发出烦人的声音，认为是它造就了这些。我实在是受不了它了，觉得要让它安静下来，如果可能的话。想着，我就站起来，费力想推开窗扉。

In the centre of the city is Li River Park near which are such scenic attractions as Folded Colours Hill, Fubo Hill, Elephant Trunk Hill, Banyan Lake, Fir Lake and some others.

中区以漓江公园为中心，包括叠彩山、伏波山、象鼻山、榕湖和杉湖等景观。

Its main food is the lichen, an epiphyte on fir and other alpine trees, and 91% of its feeding time is spent on the lichen.

松萝是它们的主要食物，取食松萝的时间占总取食时间的91%。

At the same time, the thesis points out more calculated data and more accurate on fire localization results. It is beneficial to decrease fire localization error by increasing band width of FIR filter to solve the problem of insufficient sampling points at an early stage of fire.

本文还通过仿真结果指出在带通滤波器的基础上，计算点数越多，定位估计就越准确；在火灾前期，输入的采样点数不够多的情况下，适当加宽带通滤波器的频率上限，有助于减小火灾定位误差。

There are evil-minded leaders in every generation who will seek to abuse this technology fir their own purposes.

每个时代都有抱有罪恶思想的领导者，他们想滥用克隆技术来达到自己的目的

The FIR digital filter designed with Remez exchange algorithm is applied in the processing of loran-C signal.

用Remez交换算法设计优化的FIR数字滤波器并应用于罗兰C信号处理中，然后结合这两种方法，进行去噪仿真。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。

On one hand, there are discussions with the works council and union about extension of short time working up to the end of September.

一方面，有讨论，工程理事会和联盟关于延长工作时间短至9月底。
