The singal coall property index is avaluble resolution factor in showing coal propertybut it cannot overall reflect the coal property extinctly in dynamical system. In the modern engineeting application, the intrinsic property of coal always combines with concrete facilitics and operating conditions, which exposes the vulncrability of tile singal discriminant parameter. In orderto improve the resolving ability in coal property, this article proposes the overall coal proerty evaluation system in dynamical system.

将动力用煤的燃烧特性、结渣特性以及运行的特征参数有机地结合在一起,进行综合评估.单一的特性指数在反映煤质特性方面具有一定的分辨率,但却难以全面准确地反映动力燃煤的传性.在工程应用中,煤质的固有特性又和具体设备及运行条件结合在一起,使得单一的判别指数更显得无能为力.为提高其分辨能力,特提出动力用煤煤质特性的评估体系。

Surface wave is a severe noise wave in land seismic exploration. It must besuppressed before stack in order to improve the signal/noise ratio and resolution ofseismic data. Ordinary surface wave elimination methods were developed usually onthe frequency and apparent velocity characteristics of surface wave, and bring positive effect in practice. However, these methods damage effective waves in some degree because they only lay particular emphasis on a single characteristic of surfacewave or are based on a theoretic mathematic hypothesis.By describing detailedly the surface wave field in mathematic principle, we developed a new method for wave field conversion and separation, which has beenused to desirably separate off surface wave field and effective wave field. The newmethod suppresses surface wave satisfactorily: and it also avoids the loss of effective wave energy (particularly, low frequency energy), preserves the frequency band widthof signal, and raises the signal/noise ratio of seismic data. Real data results show that it is aquite good method for prestack surface wave suppression.

面波是陆上地震勘探中的一种强干扰波,为了提高地震资料的信噪比和分辨率,必须在叠前对其予以压制。以往人们对面波压制方法的研究,基本上是依据面波的频率特性或视速度特性,并在实际应用中见到了一定的效果。但由于只侧重考虑面波的单一特性或在理论上基于某种数学假设,致使这些方法都会对有效波造成不同程度的损失。本文在用一定的数学方法对面波波场进行精确描述的基础上,提出了一种新的波场变换与分离方法,并成功地实现了面波波场与有效波波场的分离。该方法在压制面波的同时,可使有效波的能量(尤其是其低频能量)不受损失,有效地保持信号的频宽不变,提高记录的信噪比。实际资料的处理结果表明,本文方法是一种比较理想的叠前面波压制方法。

The surface wave is a strong interference wave in seismic exploration. The general methods for reducing it are: 1 D filtering, F K filtering, τ p transform, etc. that only are to pay particular attention to consider single feature or some conditional hypothesis, which have some limitation.Wavelet package transform is a method of time frequency analysis, which can do subtle division of seismic data in time frequency domain, separating surface wave effectively. After reconstruction of wavelet package, we can eliminate surface wave effectively. The wavelet package transform is a very effective noise elimination method.
