In the present dissertation, friction - induced noises emitted by a flat specimen rubbing against another flat specimen or a ball specimen under reciprocating sliding are studied. the detailed observation of the scars is conducted by means of a scanning electrical microscope ( sem ), laser scanning microscope ( lsm ), optical microscope and profilometer. the dynamic state variables are analyzed in detail using the discrete wavelet transform
使用電子掃描顯微鏡（ sem ） 、激光掃描顯微鏡（ lsm ） 、光學顯微鏡和表面輪廓測量儀等設備對摩擦噪聲發生的區域進行了詳細的觀察和分析，運用小波變換技術對摩擦噪聲狀態下的動力學變量進行了深層次的研究，應用matlab simulink語言對摩擦系統進行了振動動力學模擬，系統地研究了摩擦噪聲的形成機理。 -
Observation is particularly important where there is no permanent record of activities - discrete observation can reveal whether there is improper access to a restricted area
對于沒有持續性記錄的活動來說，實地觀察法是一種非常有效的方法。持續的觀察可以發現是否有不正確進入受限制區域的行為。 -
Samples for strontium isotopic screened were selected by way of the test of cathodoluminescence, observation of thin sections, and analysis of sr and mn. the mn / sr value of all samples presented in this paper are less than 2, and the cathodoluminescence is dull, however, the samples from the cambrian underwent diagenetic alteration to a certain degree, and the plotted points of the thickness and 87sr / 86sr value are somewhat discrete. the strontium isotope evolution curve drawn from the data with relatively low 87sr / 86sr value are consistent with other curves based on samples from different areas of the world, supporting the notion of global consistency of strontium isotope composition of marine carbonates
根據鋸同位素地層學的基本原理，利用已有的鋸同位素演化曲線，筆者確定重慶秀山寒武系剖面寒武系底界、下一中寒武統界線和中一上寒武統界線都應適當下移；另外嘗試確定了重慶秀山寒武紀剖面一些關鍵點的年齡，累積厚度1380m處的年齡為503 ? 509ma ，累積厚度1900m處的年齡約為500ma ，這對秀山寒武系剖面下、中寒武統和中、上寒武統界線的確定具有參考價值。 -
( 2 ) damage detection based on wavelet transformation using the principle of time - frequency analysis based on orthonormal discrete wavelet transformation, it can detect damage by analyzing how the frequency content of observation signal changes with time
該方法利用基於離散正交小波變換的信號時頻分析原理，通過分析觀測信號的頻譜隨著時間的變化情況來檢測破損。 -
According to the takens embedding theorem, the nonlinear time series is converted into discrete dynamic system. the prediction of time series is achieved by the observation of system states
將由系統的輸入輸出變量組成的非線性時間序列通過空間嵌入的方法轉化為一個離散動態系統，通過對系統狀態的觀測實現時間序列的預測。
