3.Every open covering of X has a finite sub-covering.每个开覆盖都有一个有限子覆盖。 4.Effectiveness Evaluation of Land Cover Classification in the Queer Mountains by ASTER Satellite Data;ASTER数据对雀儿山区土地覆盖分类的有效性评价 5.Study on Improving Multi-beam Coverage Width of Effective Scrol...
In urban areas with dense environments, base stations like microcells or small cells typically cover a radius of300 meters to 1 kilometer. The power consumption and electricity costs for these base stations are influenced by various factors, including the coverage radius, but it’s not a direct ...
A beam has a width of 300 mm and an effective depth of 480 mm strength Pc= 34 MPa. Steel yield strength fy=415 MPa. The section is to be reinforced for tension only and the effective concrete cover is 70 mm. Deadload moment is 140 ...
The influence of the height to width ratio of the cross section on the behavior of RC beams under torsion is firstly shown by using theoretical and experimental results. Next, the effective torsional strength of a reference RC beam is computed for several values and combinations of the study ...
athe efficiency of the electro-optic transceiver will be optimized when the angle between the polarization of the optical pump beam and the crystallographic z axis [0, 0, 1] is 26°. 当角度在光学泵浦射线的极化和晶体z轴0, 0, 1之间是26°,电光的 (收发器的效率) 将被优选。 [translate] ...
aFailure pattern is same as that of the beam strengthened with CFRP plate tested under static load; that is, the concrete cover peel-off along with CFRP plate. 失败样式同用CFRP板材加强的那射线一样被测试在静态负载之下; 即具体盖子peel-off与CFRP板材一起。[translate] ...
It is obvious that in a conventional SEM the way of providing beam deceleration in front of the specimen is usually restricted to specimen biasing to a high negative potential. An additional electrode, placed above the specimen and electrically connected to it, enables one to arrange for a non...
The radiation pattern is an intuitively appealing method to represent the way a directional antenna concentrates its radiated power in a beam propagating in a particular direction.

aThe failure seems to have started in the middle and since the adhesive is effective and the beam is stiff, the failure has occurred due to formation of crack in the cover concrete along the rebar resulting in cover peel-off (Fig. 8). 失败在中部似乎开始了,并且,因为胶粘剂是有效的,并且...
