对单道记录或多道记录中任选道的仿真实验表明，与传统的基于径向基核函数的支持向量回归及褶积滤波方法相比，使用本方法去噪后的同相轴更为清晰，波形恢复得更好，信噪比也较高，因此有可能将其应用于地震勘探记录的去噪处理中。

The findings: with the apparent dominant frequency of the Ricker wavelet rising, the detection SNR will get worse gradually, it is obvious that the variety of the SNR is slower during the portion of high frequency than during the portion of low frequency; in the usual range of seismic prospecting frequency, the SNR of the chaotic oscillator detection system could partially make up the amplitude attenuation aroused by the transmit of the seismic wave; the results could provide help for detecting the event constituted by aberrant wavelets.

本文以Ricker子波模拟地震子波，研究Ricker子波视主频变化的相应检测效果。研究结果：随着Ricker子波视主频的升高，检测SNR逐渐变差，在高频部分SNR的变化明显比低频部分缓慢；在通常地震勘探频率范围内，混沌振子系统检测SNR有可能部分补偿由于地震波传播引起的幅度降低；为检测由畸变子波构成的同相轴提供一定的可能。

From the fields of regional crust-mantle structure, metallogentic settings, history of tectonic-magmatic activity, distribution of high antimony anomaly, characteristics of deposit, origin of ore-forming materials (including Sb, C, Si, S, solution and associated elements), black dikes, the relation of deposit and mantle metasomatism fluid is expounded by means of geology and geophysics. Xikuangshan antimony deposit is proved to be a typical vein deposit formed by mantle metasomatism fluid. On the basis of this knowledge, the prospecting criteria of blind orebody of the deposit are given as follows: extensive structuer which indicating the activities of mantle metasomatism fluid, change of host rocks (especially exsisting shale barrier bed), silication and carbonization alteration.

The ore body occurred adjacent to the granite, thus it is inferred that mineralization stage is syngenetic or slightly later than emplacement of the granite, suggesting that mineralization of Mo, W, Pb, Zn and Ag was closely related to emplacement of the Yanshan period granites, and providing a new model for prospecting intrusive-related resource inside the volcanic rocks.

由于矿体赋存于岩体顶突部位的蚀变花岗岩中，预示成矿为花岗岩侵入的同期或稍后，即钼钨铅锌银成矿与燕山期花岗岩侵入活动密切相关，这对于火山岩内寻找与侵入岩有关的矿产提供了新的思路。

Mineralogic characteristics of quartz of this gold deposit, such as REE, fluid inclusion, chemical composition, unit cell parameter, infrared absorption spectrum and thermoluminescent effect, were studied systematically in this article,and some valuable information of genetic and prospecting criteria are concluded.
