Conditions for high resolution recording of LLFT-ray holograms are studiedby means of computer simulation. Digital reconstruction of simulated LLFT X-my hologram iscarried out successfully and effect of reference dimension, a key parameter, on resolution Ofthe reconstructed image is also studied. All these will benefit further experimental researches.

The dimensional instability of cotton knitted fabrics makes it imperative to establish a reference state for the evaluation of properties and measurement of dimensions. This report analyses the factors which influence the dimensions of reference state in knitting,dyeing and finishing process. Some measures for the control of reference dimensions have been discussed.

对于尺寸易改变的棉针织物,很有必要建立其基准状态,并对其基准状态的性质和尺寸进行研究。本文研究了编织、染色和整理过程中影响棉针织物基准状态尺寸的各种因素,提出线圈长度对基准尺寸有决定性作用,染整工艺及染整条件对基准尺寸影响很大,应严格控制。

This paper measures the drag, lift and moment of two kinds of typical bridge deck sections with different ratios of width to height (B/H) in TJ-2 wind tunnel. The testing Reynolds number spans about 2 order, which the typical reference dimensions is bridge deck height .The Reynolds number effect of the mean aerodynamic force coefficient is studied; the influence of ratio of bridge deck width to its height on three mean coefficients is shown too.

This paper measures the drag, lift and moment of two kinds of typical bridge deck sections with different ratios of width to height (B/H) in TJ-2 wind tunnel. The testing Reynolds number spans about 2 order, which the typical reference dimensions is bridge deck height .The Reynolds number effect of the mean aerodynamic force coefficient is studied; the influence of ratio of bridge deck width to its height on three mean coefficients is shown too. The results show that∶① The mean drag and lift coefficient have considerable Reynolds number effect between the streamline-liked and the Π-type bridge deck section;② Between the two type deck sections, the trend of mean drag coefficient varying with Reynolds number is opposite to each other, which challenges the traditional opinion on the blunt section;③ the ratio of width to height(B/H) affects on Reynolds number effect of the mean aerodynamic force coefficient obviously;④ the turbulence can reduce the mean force coefficient Reynolds number effect effectually.

在TJ- 2风洞中 ,测量了近 2个数量级的雷诺数范围内不同宽高比的 2类桥梁断面的三分力 ;研究了桥梁断面三分力系数雷诺数效应、宽高比对断面三分力系数雷诺数效应的影响 .近流线型桥梁断面的阻力系数、升力系数都有明显的雷诺数效应 ;Π型断面阻力系数雷诺数效应与近流线型断面规律相反 ,升力矩及升力系数雷诺数效应不明显 ;宽高比对三分力系数雷诺数效应有明显的影响 ;紊流可以作为抑制阻力系数雷诺数效应的有效措施
