传统概念问题的当代形式逻辑剖析

尽管传统形式逻辑在概念问题上不研究大于1的n元名词而只研究仅占n分之1的1元名词，可是在这n分之1的研究中仍然存在着不少缺陷。譬如，关于概念的定义至今仍不能自圆其说；有些概念种类划分不合理；给概念内涵下的定义产生歧义；给普遍概念下的定义过宽；等等。传统形式逻辑是真正的逻辑科学，我们剖析的目的是深深地切望传统形式逻辑深刻正确的主导思想和久胜不衰的理论成果得到发扬光大。

Study on effect of segments erection tolerance and wedge-shaped segment on segment ring in shield tunnel

INTRODUCTION Shield tunnel method has become the most pre- ferred method in city tunnel construction because of its excellent attributes: little effect on surrounding environment, fast and safe construction, outstanding performance in earthquake resistance, etc. (Zhang et al., 2004). In different shield tunnels, the arrangement and number of segments are different, but the whole assembling process is generally the same. The as- sembling process begins with A2P, then A1P, A3P, BP, CP, …     

Simulation of Fragment Impact on Multi-Layer Targets Using Contact Method

Cased explosives generate highly energetic fragments as their casing breaks up. Due to the complexity of casing fragment related behavior such as embedment, perforation and ricochet, it may be insufficient to use equivalent triangular pressure loading in fragment impact simulations. This simplified method may over- or under-predict the target response. Recently, a procedure using contact techniques has been proposed to overcome such difficulties. It has been shown that the new method has the inherent capability in modeling the multi-piece and multi-hit fragment impact problems in a more realistic way. To investigate the applicability of the proposed method to simulations involving multi-layer penetration, the selected problems of fragment impact on multi-layer targets are described in this paper. It is demonstrated that this method is capable of predicting the complicated multi-layer structural response caused by fragment impact and penetration. Modeling procedures and some technical issues are also discussed.
