摘要彈匣弧形部擦劃痕跡是射手在以壓推方式向彈匣內壓裝槍彈過程中，彈殼體與彈匣弧形部內邊棱相摩擦而形成的痕跡。 -
In addition, this article also researched the friction marks of steel ball after long - time friction tests with sem images and spectrum analysis, and summarized the principle how to reduce friction and wear of three prescriptions
另外，本文還利用sem圖像和能譜分析等手段，對長磨試驗后的鋼球磨痕情況進行了研究，歸納總結出了三種配方的減摩抗磨和自修復機理。 -
And friction marks indicated that they did, indeed, once form part of a necklace or bracelet
事實上，這些殼上的摩擦痕跡顯示他們曾經是項鏈或手鐲的一部分。 -
Acceleration scuff : friction marks that occur when the tires on the drive wheels of the vehicle are turning faster than they would normally turn, given the speed of the vehicle

At first it analyzes the bedding rock slope ' s bedded rock and its incontinuity face, and studies the stress, strain, stability ' s condition of the bedding rock slope, fully considering the cohesive force of rock layer and incontinuity face. geologic mechanics models of two types of bedding rock slope are set up, the instability coefficient of bedding rock slope under different mechanical parameters is computed, and the conclusion that the stability of bedding rock slope is relation to rock layerer, cohesive force of incontinuity face, inner friction angle and rock layer obliquity has been gotten. based on the above discussion, the thesis comes down the influence of rock layer and the incontinuity face on the bedding rock slope to incontinuity face ' s influence factors, and discusses other factors that influence the bedding rock slope ' s stability, so gains the evaluating and forecasting index marks
本文首先對順層邊坡的層狀巖體及其中的層理面和不連續面進行了分析，對其應力應變進行了研究，得出了順層邊坡的穩定性不僅與巖體中巖石的強度有關，還與巖體中層理面及不連續面的內聚力、內摩擦角及其傾角有關；論文建立了層理面和節理面的地質力學模型，討論了其力學參數變化對邊坡穩定性的影響，並在此基礎上將層理面和節理面歸納為順層邊坡穩定性的結構面影響因素，同時討論了影響順層邊坡穩定性的其他因素，從而得出順層邊坡穩定性的評價預測指標。 -
