The results indicate that a stable deformation localization band occurs in the coal cutting course and develops to macroscopic crack ; the deformation localization band is slantwise ; while the cutter tooth is used, the deformation localization develops slowly, and the localization becomes wider and the strain value in the band area higher afterwards ; when the point - attack pick used the localization develops quickly and the localization band becomes narrow and the strain value in the band lower
研究表明：
截齒
截割煤體過程中，煤體出現穩定的變形局部化帶，且最終發展為宏觀裂紋；煤體變形局部化帶為一個傾斜帶：刀齒
截割時，變形局部化發展較慢，但產生變形局部化后，局部化帶寬且帶內應變值較高；而鎬齒
截割時，變形局部化發展較快，但產生局部化后，局部化帶窄且帶內應變值不如刀齒高。
The frozen coal destruction is the tension stress destroys, and establish the frozen coal cutting model in this foundation, obtains the cutting force, feeding force, tooth spacing according to the smallest energy principle. bring forward a rotary drilling mothod to unload the frozen coal, the broken ability is strong, without frozen depth limits, then obtains this machine working parameters, has combined this method with a grab and determined the plane of vehicle - carried rotary drilling movable coal - unloader
凍煤破壞是拉應力破壞，在此基礎上建立了凍煤的切削模型，根據最小能量原理得到
截割力，進給力和
截齒間距的計算公式，分析得到
截割力與切削厚度成正比，隨著前角的增大而減小;
截齒最優
截距與
截齒尺寸有關且與切屑厚度成正比;進給力隨著
截齒前角增大而增大的規律。

On the other hand, they play an important role in the theories of esfimation for regression function. in this paper, we mainly get the large sample properties for partitioning estiona - tion and modified its estimation. for example, we proved their asymptolic normaity under nuture conditions by means of mortingle theory ; we also get their strong consistency for regression function under censored samples ; and finaly we genearzed the result to dependence sample and have strong consistency for the modified partitioning estimation of regression function
