In the aspect of the force analysis between cycloid disk and pin wheel, a kind of force analysis method of the mesh with initial clearance is put forward in allusion to the teeth profile of the equidistant and radial-moving combining modification, which is more accord with the actual engineering.

该方法主要是从整个传动过程中动态地考虑摆线轮与针齿齿面的受力情况，依据摆线轮与针齿的实际最先接触点的分布区间不同，对不同的等距与移距组合修形方式分别给出了动态受力分析方法，并且在整个传动过程中进行了优化搜寻，从而得出了整个传动过程中的接触力动态变化规律，相对以前的受力分析方法，计算的精度和准确性得到了提高。

After the initiation of crack, the crack propagating of alloys with 0.5%Ce addition is accelerated evidently because of the appearance of needle rear earth rich phases which dissever the matrix and lead to the decrease of mechanical properties and thermal fatigue resistance.

加入0.5%Ce的合金在裂纹形成后期扩展速度明显加快，这是因为合金中出现针状富稀土相，这种针状相割裂了基体，使得合金力学性能降低、热疲劳抗力下降。

The in-plane equivalent elastic modulus and tensile strength of stitched composite laminates are studied, and its found that the in-plane equivalent elastic modulus decreases with the increase of stitch density, stitch thread diameter, maximal misalignment angle and the distortion width, and the range is about 5%. The tensile strength of stitched composite laminate increases with the increase of stitch step and decreases with the stitch space.

研究结果表明：随着缝纫密度、缝纫线直径、最大纤维偏转角和缝纫变形区宽度的增加，缝纫复合材料层合板面内等效模量逐渐降低，最大降幅一般在5%左右；缝纫复合材料层合板的拉伸强度随缝纫针距的增加而增大，随缝纫行距的增加而降低，因此缝纫密度对拉伸强度的影响程度要看具体的缝纫针距和行距。

Comprehensive analysis is done to the selection of wires of cylinders,doff rollers flat tops, precarding board s,and installation of carding attachment,as well as the effect and related factors with the inrease of speed and capacity,proper installation of under precarding board s is necessary for carding quality and spinning quality.

详细分析了锡林、道夫、刺辊齿条、盖板针布、预分梳板选配原则及安装附加分梳元件———分梳板的效果及影响因素，指出随着梳棉机的高速高产，应合理选配针布齿条，而加装前后固定盖板，刺辊下预分梳板是改善梳理质量和成纱质量的有效手段。

To discuss the effect of pin carding plate on fiber length distribution in the card slivers,length tests to the card slivers under different carding plate gauge,taker-in speed and doffer speed using pin carding plate and saw-tooth carding plate under the card taker-in by USTER AFIS single fiber tester were done.

为探讨梳针分梳板对生条中纤维长度的影响，用AFIS单纤维测试仪，对在梳棉机刺辊下分别加装梳针分梳板和锯齿分梳板时在不同分梳板隔距、刺辊转速、道夫转速条件下所加工的生条进行长度检测。

To research the effect of pin carding plate on removal of impurities from card slivers,impurities tests were carried out for the card slivers under different gauges,taker-in speeds and doffer speeds using pin carding plate, saw-tooth carding plate and taker-in grid under the card taker-in by USTER AFIS single fiber tester.

为研究梳针分梳板对去除生条中杂质的影响，用USTER AFIS单纤维测试仪对梳棉机刺辊下加装梳针分梳板、锯齿分梳板和采用小漏底在不同隔距、刺辊速度、道夫速度条件下所加工的生条进行杂质检测。
