查询词典 depth to width ratio

Also using the exterior expression for the Graf′s addition theorem, the exact solution for scattering of plane SH waves by circular arc alluvial valley is presented in the paper. From the numerical results the complex effect of the depth-to-width ratio of the alluvial valley on the surface ground motion is found.

利用Graf加法公式的外域型表达，本文还给出了任意圆弧型沉积盆地出平面散射的精确级数解答，提供了大量数值结果并指出了盆地深宽比对地面运动的复杂影响作用。

These measures are as follows: shorten the primary wind intervals to improve thermal load of the burner; reduce the size of hypothetical circle of contact to prevent the flame from splashing; use nozzles with larger height/width ratio to increase the effusive rigidity, so as to increase the jet flow depth of secondary wind into the main jet flow; use a higher primary wind velocity to increase its jet flow rigidity; use a special flame holder structure of the primary nozzle, so as to improve

实践证明，采用这些方式最终有效解决了炉膛结渣问题，并切同时兼顾了锅炉热效率与炉内燃烧的稳定性。

According to the influence of each laser parameter on processing and the advantage that a laser can achieve high laser quality nearby the last threshold,AOM Q-switched Nd∶YAG pulsed laser is adopted for microdrilling. As a result,the 15μm microhole in 0.7mm-thick zincification plate steel is obtained,and the ratio of depth and width is over 50,100% drilling rate is acquired.

基于各个激光参数对加工微孔的影响以及激光在阈值附近工作时光束质量较好的优点，采用声光调QNd∶YAG脉冲激光器进行阈值附近的微孔加工，在0.7mm的镀锌钢板上获得了直径为15μm的微孔，深径比超过50，打孔成功率为100%。

At the same time, the program corresponding to the proposed method is compiled in FORTRAN90, which is used to analyze the influence of several factors on the behaviour of barrettes, including ratio of length to width, ratio of depth to equivalent diameter, ratio of modulus of pile to soil, Poissons ratio, pile soacing etc. Many useful conclusions are obtained from the above analyse.

该方法考虑了壁板桩桩身横截面的非轴对称性，并用FORTRAN语言编制了相应的程序，进而分析了多种因素对壁板桩承载特性的影响，包括长宽比、桩径比、桩土刚度比、泊松比、桩间距等。

The results show that single structure parameters (width and depth of flow path/passage, and height, and angle of dentations) are local and difficult to represent the anti-clogging ability of emitters. Characteristic structure parameters(minimum size of cross section, hydraulic radius and dentitions spacing) can represent the anti-clogging ability of emitters in a sense. There are anti-clogging critical values under the test. Rated flow Qr and the ratio of diameter of labyrinth passage to diameter of particle η are well cor related to the anti-clogging ability and have anti-clogging critical values too.

结果表明：用单一结构参数(流道宽度 W 、流道深度 D 、齿高度 h 和齿角度θ)表征其抗堵塞性能存在局限性；结构特征参数断面最小尺寸 min(D，W、水力半径 R 和齿间距 l 能较好反映滴头流道横、纵断面的结构特征，在不同程度上表征了流道的抗堵塞性能，且在试验条件下各自均存在抗堵塞临界值；滴头额定流量 Qr 和迷宫滴头径粒比η与抗堵塞性能相关性较好，且存在抗堵塞临界值。

By studying the processing properties of the self-leveling HM199 room temperature vulcanized sealant for airport runway joint ,it is revealed that the appropriate ratio of the sealant injection depth to the width of joint is 1∶2,but the injection depth should be no less than 6mm,and the recess from pavement to sealant is 3 mm to 7 mm.

阐述了机场跑道接缝密封剂和衬垫材料应具备的性能；通过对自流平型HM199室温硫化密封剂灌注工艺性能的研究，提出密封剂的灌注深度与接缝宽度的最佳比为1∶2，灌注深度最小不低于6 mm，密封剂顶部与道面的距离为3~7 mm。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
