(二)负中心质效应在本文三(二)中已对负中心质作了比较详细的讨论。因为作为负中心质的孔缝是各种混凝土的重要组分,对性能有重要影响。迄今为止,在水泥混凝土的科研文献中,孔缝的研究报告占相当大的比重;但是关于负中心质效应问题,迄今还很少涉及。负中心质对于周围大介质的影响是比较明显的。例如,在荷载作用下,孔缝附近的大介质常发生较大的变形,产生较大
(II) Negative masculine effect In the third (II) of this article, we have discussed the negative center mass in more detail. Because the aperture as a negative center is an important component of various concrete, it has an important effect on performance. Up to now, in the scientific research literature of cement concrete, the research report of the pore gap has occupied a considerable proportion; however, the problem of the negative masculine effect has so far been seldom involved. The influence of negative center mass on surrounding large medium is more obvious. For example, under the action of the load, the large medium near the hole often undergoes large deformation, resulting in large
