The influencing factors of coal arch camber in planomural coal bin and coal drop pipe with rectangular or circular cross section during coal drop are studied theoretically.

对落煤过程中平壁煤仓及截面形状分别为矩形、圆形的落煤管起拱的影响因素进行理论研究。

By analyzing the mechanics relation between the sprocket wheel and the pallets of the pallet draught device in a sintering machine,the non-arching mechanics model of the pallets was established and the force control method for the non-arching sintering machine was put forward.

通过分析带式烧结机台车执行牵引装置的星轮和台车的力学关系,建立了台车无叠肩起拱的力学模型,提出了无叠肩起拱带式烧结机的力控制方法。

The curvilinear shape of sprocket wheel is the main cause of arching phenomenon of sintering pallets in the return rail.

起拱现象的存在,会造成台车端部不均匀磨损,降低台车使用寿命,增大烧结机漏风率及负荷。

The garment quality has some direct thing to do with construction design and production processing, also the garment fabrics play an important role on it In this paper, the tailoring property of garment fabrics is discussed about the effects of fabric strength and elongation, yarn density, fabric thickness and yarn process on seam strength, seam bulging and needle damage et a

文章就服装材料的强伸度、纱线密度、织物厚薄及纱线工艺等因素对线缝强度、线缝起拱、针伤等方面的影响 ,探讨了服装材料的缝制加工特性。

A regression equation indicating the relation between the fabric bulging height and weight, and between the fabric weight and compactness is derived from the test and analysis of the bulging height of heavy_weight silk fabrics conducted by self_made bulge tester, thus offering data support to the design of proper weight and compactness of the fabric for bulge proofness.
