研究表明，合成梁式的结点可用于无伸缩缝桥梁设计；在满足设计承载力的情况下，桥台的高度和长度宜取小值；桩存在一个合适的相对刚度，当桩相对刚度超过这个值时，对合成梁式的结点受力几乎没有影响。

Supporting type is suggested to be developed into 3-prop to improve adaptability besides 2-prop and 4-prop. The difference of caving difficulty degree of coal seam is the base of caving coal method at high, medium and low position. Caving with small step and open caving flashboard used widely not only cause serious mixture of coal and rock but also hinder the improvement of top coal recovery. So we suggest caving with large step or closing caving door. Four-bar-mechanism of hydraulic support restricts development of new style caving powered support. Stabilization framework of expansion link and all-shield caving tail beam at high, medium and low position are introduced here.

支架支护型式，除了两柱、四柱以外，建议开发三柱支架以改善适应性；煤层冒放性的差异，是高位、中位和低位放煤方法存在和使用的依据；目前广泛采用的小步距放煤和开放式放煤插板不仅造成严重混矸漏矸，也妨碍顶煤回收率的进一步提高，建议采用大步距放煤和可关闭放煤口；液压支架四连杆稳定机构，制约了新型放顶煤液压支架的开发，介绍了液压支架伸缩杆稳定机构及全掩护拖移高位、中位和低位放煤尾梁。

The definition of Wavelet Analysis is that shifting the mother wavelet e.g. which has limited energy, such as shifting for, then proceeding dimensions, we obtained wavelet basis function ,, which make the inside product to the function to analysis With the Fourier transformation to the and, then the equivalent frequency spectrum of wavelet transformation can be expressed as where 、 are the transformations of 、 respectively and i is an imaginary number unit.

小波变换的含义是：把一具有有限能量的母小波，如进行移位后，再进行尺度的伸缩得到小波基函数为然后与待分析的函数作内积，即对和作Fourier变换后，可得到小波变换的等效频域表示为：其中、分别是、的Fourier变换，i为虚数单位。

The porterage machine hand of this text research has 5 freedoms degree, can carry out the bedrock to revolve, the rise and fall and stretch and shrinks of the arm, the wrist revolves to clip with the hand claw tightly.

本文研究的搬运机械手具有5个自由度，可实现底盘的旋转，手臂的升降及伸缩，手腕的旋转和手爪的夹紧。

Hexachlorocyclophosphazene was prepared using phosphorous pentachloride and ammonium chloride as raw material, hccp was mixed with Montmorillonite which aimed to decrease MMT.'s hydrophilicity. Solid state reserve cell of Mg│reformed MMT.│polymer gel containing water│graphite was assembled, and cell performance was tested. XRD and IR results show: When mass percentage lower than 9.1%, hccp mixed with MMT to form homophase, hccp phase was observed in the mixture when percentage higher than 9.1%, for hccp specific diffraction peak appears in XRD data, and 1220cm-1 which was assigned to P=N double bond 's expand vibration appears in IR data.

合成了六氯环三磷腈，并用六氯环三磷腈与蒙脱石混合对其改性，期望能减小蒙脱石的吸水性能；组装电池Mg |改性蒙脱石|含水凝胶|石墨片，并测试电池的性能。X射线粉末衍射数据和红外光谱数据表明：蒙脱石容纳六氯环三磷腈的质量分数在4.8%-9.1%之间，可与蒙脱石形成单一物相，但混合质量分数大于9.1%时，改性蒙脱石出现六氯环三磷腈的特征衍射峰，和1220 cm-1的六氯环三磷腈P=N双键的特征伸缩振动峰，证明为蒙脱石与六氯环三磷腈的两相混合。

The two stage telescopic lattice frame is composed of three boom sections sleeve-mounted together, tail end of the outmost basic boom frame is pivot-connected respectively with slewing mechanism and luffing mechanism on the chassis; the inner two section booms can telescope freely like a retractive antenna to change the delivering distance of the conveyor and the operating radius.

两级伸缩臂架由套装在一起的三节臂架组成，最外层的基础节臂架尾部和底盘的回转机构、变幅机构分别铰接，固定于底盘上；内层的两节臂架可如拉杆天线一般自由伸出和缩回，改变输递机的输送距离，从而改变施工半径。
