 Based on the research results of screw threads measurement with wires (ball), three universal calculation programs for outer and inner threads are presented in this article for easy calculation of various parameters (M, Mn, K2, D2, d2, 2Rd) of normal thread and trapezoidal thread in the field. They are also suitable for the calculation of the middle diameter d2 of Buttress thread. 本文根据螺纹跨线(球)测量的研究成果,给出三种适用于外螺纹和内螺纹的通用计算程序,便于在生产现场计算普通螺纹、梯形螺纹的各种测量参数(M、M_n、K_2、d_2、d_(2单)、D_2、D_(2单)、2R_d)和特性参数,也可以计算锯齿螺纹中径d_2。 短句来源 Limited Condition of Conical Shell Designed on the Basis of Middle Diameter Formula 锥形壳体按中径公式设计的限定条件 短句来源 ③ The rotation is 5～6 years for cultivation of stand for small diameter timber used for paper—making and particle board, but 6～9 years for middle diameter of timber used for core board, match and furniture and 10～12 years for large diameter of timber used for plywood. ③培育造纸、刨花板等小径材林分的轮伐期为5～6a,木芯板、火柴、家具等中径材的轮伐期为6～9a,培育胶合板等大径材的年限则需要10～12a。 短句来源 By a synthetic analysis of mill run, the cost of production and output value, planting density of cultivating short rotation industry timber could be determined as 3 333～5 000 trees5hm -2, to cultivate large or middle diameter timber, it could be determined as 1 667～3 333 trees5hm -2. 经出材量、生产成本与产值核算 ,培育短周期工业用材林宜采用B～C间的密度 (3333～ 5 0 0 0株·hm- 2 ) ,培育大、中径材宜采用A～B(16 6 7～ 3333株·hm- 2 )间的密度。 短句来源 On account of size,automatic submerged arc seam welding cann’t be applied into middle diameter pipe(from 219 mm to 1300 mm). 由于尺寸原因埋弧自动焊在中径管 (管径在 2 1 9～ 1 30 0 mm之间 )内缝焊接上无法应用。 短句来源 更多

 Twelve-years test for Pinus taeda shows that significant differences existed in growth among different provenances. The averaged height, diameter at breast height(dbh) and middle diameter for 12-year growth are 40.2%,78.8% and 103% greater than those of Pinus massoniana. 通过12年的火炬松种源试验研究表明,火炬松种源生长性状差异极其显著,12年生平均树高、胸径和树高中央直径分别比对照马尾松大40.2%、78.8%和103%。 短句来源

 middle diameter
 This study employs a new low-velocity test to obtain ultralow flying height with sustained intermittent asperity contacts and random seek accessing in a region near the middle diameter of the disk. However, they differed significantly in such quantitative characters as plant height, middle diameter, days to flower, node number and fibre yield/plant.
 This paper discussed process of the infereneing and resolving for formula computed middle diameter on the optimal sorting. We have computed with simple and convenient method on the computer, arranged reasonably for whole computing process and used fully intermediate data, so that one can economize larger for computer internal storage location and computing time. 本文论述了“最优分割法”中,段的直径计算公式的推导分解过程,采用最简便的数学形式在计算机上进行运算,并对整个计算流程做了合理安排,充分利用了中间性数据,使计算机内存占用量及计算时间得到了较大节省。 In a physical check-up of 649 aged persons, 74 cases with symptom of cervical spond yiosis and 52 cases without symptom were studied radiographically with measuremets of the sagittal middle diameter (SMD) of cervical spinal canal as chief criteria. 在649名老年人的体检中,对有颈椎病症状的74人和无症状的52人抽样进行了X线平片检查及测量。测量结果:无症状组以C_4的椎管矢状中径最小,其余C_(3～7)均比较接近。有症状组的椎管矢状中径一般较无症状组小3 mm左右,而颈椎体的矢状中径都较后者大1mm左右。结果表明,无症状组C_(3～7)的比值皆大于0.75,而有症状组却有4处小于或接近0.75。根据本组资料来看,无症状组的软组织钙化发生率(50％)与有症状组(56.76％)差别不大。因此,有无软组织钙化,对于诊断颈椎病的价值可能不大。 The relationship among the paramters of two radial gratings such as middle diameter, angular pitch and width of frings can be calculated by means of a calculation programe.A parts of the result are given in this paper in order to analyse the relationship of each Parameter. 通过编制的计算程序来计算径向光栅的刻划中径,角节距,条纹宽度等参数之间的关系。本文整理了部分计算结果,从而用来研究各参数之间的依赖关系。 << 更多相关文摘
