There are two kinds of analogy method for the beam on elastic foundation in distortion computing of simple cell box girder bridge, one of which is to use the distortional angle v as a parameter and the other is the distortional deflection w.In this paper, by studying the two methods, we found that v exists some possible errors which result from constructing a loading distortional component which don't accord with the preconditions of St. Venant's local influence principle.

There are two kinds of analogy method for the beam on elastic foundation in distortion computing of simple cell box girder bridge, one of which is to use the distortional angle v as a parameter and the other is the distortional deflection w.In this paper, by studying the two methods, we found that v exists some possible errors which result from constructing a loading distortional component which don't accord with the preconditions of St. Venant's local influence principle. Actually, it is a approximate way to use distortion angle v for analoging the box girder's flexure on distortion which results in complication for various rigidity formulae and undistinguishable on the physical concept. The chief weakness of the method is only suitable for rectangular box girder.The w method is more fair and reasonable as comparedr with v method, because the w method is direct analogy one. As the deflection and moment of the beam on elastic fcundatica is found, and the solution of box girder is just obtained, by which the conception is clear; the calculation is simple and quick; the results are more accurate and particular and it is practical for inverted trapezoid box girder bridge. But its I_b formula of beam on elastic foundation is based on rectangular box girder.In order to improve it, the general formula of I_b has been derived in this paper which is advanced in increasing the accuracy of distortion computing on inverted trapezoid girder.

单室断面箱梁侨畸变计算,目前,有两种弹性地基梁法;一种以畸变角ν、另一以畸变挠度ω为参数。 本文通过对两种方法的研究,发现ν法由于构造的荷载畸变分力不符合圣维南局部影响原理的先决条件,存在某些可能的误差。用畸变角ν比拟箱梁的畸变弯曲实际上是近似的方法。导致各种刚度公式的复杂化,和物理概念不明晰;主要弱点是仅适用于矩形箱梁。与ν法比较,ω法是较为合理的。因为ω法是直接比拟法,求得弹性地基梁的挠度和弯矩,就是箱梁之值。它概念清晰,计算简捷,结果也较为准确。特别它适合于倒梯形箱梁桥。但它的弹性地丛梁的I_b公式是根据矩形梁得出的,为了改进,本文导出I_b普遍公式,它对提高倒梯形箱梁桥的畸变计算精度是有益的。

To the question of the bigger dispersion of burst height and the lower antijamming property in continuous wave Doppler radio fuzes, a microcontroller fuzes system is designed. The paper uses the interrelated comparative ways to extract target information, uses the division offset influence principle to reduce factors affecting the dispersion of burst height, and uses the tech-nique of digital filter, false alarm threhold close target to realize antijamming. A series of labo-ratory simulation tests have shown that the circuit possesses fine features in stabilization of the burst height, as well as abilities in antijamming from early burst, big pulse delayed signals and peak signals.
