1.Aiming at a variety of types of planar space grid truss,this paper has systematically put forth the theory and techniques of sloping in equal altitude for roof of space grid truss in common use,set up the way of forming slope in eq. ual altitude,derived a series of formulas capable give out accurate geometrical relationship of truss sloped and given analysis to express the influence on behavior of truss as a result of being sloped.
2.Therefore, the method of screen spreading is presented herein with the following basic feature: taking the surface of the perpendicular line at the end of the distortion and bottom as the datum plane, move the controlling point of every distortion part to the datum plane with the principle of changeless of geometry size, and then the spreading is formed.
4.We know very little about the early Semitic religions, but the Semites that invaded Mesopotamia seem to have completely abandoned their religion in favor of Sumerian religion.
5.The researches into the Bohaiwan basin indicate that the structural slope_break zone in the fault subsidence lacustrine basin constrained the change in the accommodation space of the basins, controlling the development of the depositional sequence and the distribution of the depositional system tracts and the sand bodies.
6.This paper analyzes on the common quality faults of cement mortar screed-coat in the roofing construction such as the inaccuracy of the slope-making,the unsmoothness of the drainage,and the sanding,peeling and cracking of the screed-coat,etc.,and advances some corresponding precautionary measures.
7.Based on "The Murder in the Rue Morgue" and "The Purlioned Letter" and three other detective stories by Edgar Allan Poe, this paper focuses on the creation of the four elements and functions of the pattern of Western detective stories.
8.Product function :soft soil subgrade strengthening , reinforced embankment &slope, strengthening separation, bounding deformation of foundation, prevent road from reflection crack, increasing the intensity of subgrade .It can strengthen soft subgrade of kinds of roads and railways; prevent road from reflection crack; enhance the strength of subgrade ;reinforcedriverbank , embankment and slope; homogenize the stress; adjust settlement; improve the stability and bearing capacity of the basement; strengthen road and bridge tops.
