- 摘要：City residential structure is the main aspect of city spatial structure and in western countries it has been experienced three phases: centripetal collection, centrifugal pervasion and organic collection.From the viewpoint of historical development, the evolvement of residential structure in China can be summarized in three phases: archaic city, neoteric city and modern city.The character of city residential structure is different at different times.However, the residential sub-urbanization and the residential redistribution are the two central forms of the evolvement of residential structure in the modern city.516|8|0更新时间：2023-11-28
- 摘要：The rural urbanization process in Chongqing is much slower than that in other metropolitans and most of the provinces in eastern China, which can't adapt to its important function as the economic and cultural center in southwestern China.It is urgent for Chongqing to accelerate the rural urbanization for improving its whole urbanization level and speeding up its economy development to catch up with other metropolitans and some advanced provinces.Compared with the urbanization in other metropolitans and some provinces, the authors demonstrated the rural urbanization situation and its characteristics in Chongqing in details, analyzed the reasons for the poor urbanization and its influences on the social-economic development especially that in the rural area.Inferior position of Chongqing's small towns in the market competition with those from other provinces is one of the results of its poor urbanization development.At last, the authors suggested a few practical countermeasures to improve the rural urbanization in order to get a rapid and sustainable rural development and to increase the whole economic effects of the metropolitan.397|8|0更新时间：2023-11-28

- 摘要：For prestressed frames, the axial compression ratio will affect not only the ductility of structures but also the structural internal force.Based on the computer-calculation for four groups of 24 prestressed frames combined with the references, in this paper, the effects of axial compression ratio on the prestressed frames are studied and discussed through three aspects: the second-order effect, the axial deformation of frame-columns and the comparison with ordinary concrete frames.The study results show that the effects of axial compression ratio on the prestressed frames and the ordinary concrete frames are basically consistent, but there are some self-born characteristics.As a whole, the effect of axial compression ratio on the prestressed frames is more notable than that on the ordinary concrete frames, but under common situation the effect is small.546|423|0更新时间：2023-11-28

- 摘要：In order to solve the problem that the internal force of statically indeterminate prestressed and reinforced concrete bar system structures is difficut to determine when the structures come to the non-elastic state, a simple analysis method of experimental structures' internal force-sectioned dropping rigidity method is brought forward.In this method, according to the loading state of bars, the bars are divided into limited segments by the level of rigidity dropping, and the relative level of each segment is enacted; then the dropping modulus of each segment rigidity will be found by debugging time after time, and the checking point is the key distortion which was gained from the experiment; it is considered that the internal force which is calculated by elasticity analysis at the dropped rigidity can reflect the real internal force of the structures.It is basically proved that the method, which is brought forward in this paper, is effective by comparing its results with those from the experiment of a large size prestressed frame of two spans and single floor, of which the internal force redistribution is considered.533|579|0更新时间：2023-11-28

- 摘要：On the assumption that the runoff on the catchment of each gully flows into the gully itself, in this paper, a model of surface storm-water runoff at urban gully is presented, which includes runoff sub-model and concentration sub-model.The runoff sub-model describes the rainfall event with instantaneous rainfall intensity, the runoff-generated event with runoff coefficient of integrative area and the runoff converged event with the principle of equal time of flowage.The concentration sub-model shows that the pollutant concentration event only changes with the runoff event at the gully.In this paper, the concrete form of the model for two gully inlets in Shapingba District of Chongqing is given.The model is calibrated with the data from the synchronized measurements of water quantity and quality at the two gully inlets obtained from July to September 2000.The relative error is calculated by comparing the model predictions with the field-measured results.598|8|0更新时间：2023-11-28
- 摘要：In this paper, the low-temperature plasma was applied to treat the surface of the fibers.The results show that the surface energy of the treated fibers increases greatly so that the fibers can be wetted very well by resin and the adhesion strength of the treated fibers to resin increases significantly.The mechanical characteristics of the PE composites are improved by the surface treatment of the fibers.In this paper, the mechanism of treatment has been discussed.The varieties of polar oxygen containing groups produced in the surface layer which form chemical bonding and the plasma etched pits spreading all over the surface of the treated fibers into which the resin penetrates to form the mechanical interlacing between fibers are the two reasons for the improvement.664|15|0更新时间：2023-11-28
