Estimating dimensions of flaws with narrow openings along the beam direction
      
The problem of flaw dimension measurement along the beam direction is discussed from the viewpoint of the measurement accuracy.
      
Practical recommendation are put forth for estimating dimensions of flaws with small openings, such as incomplete fusions in welded joints, along the beam direction using X-ray photographs.
      
When a light beam propagates perpendicularly to colored lamellas, the dichroism is much larger and the birefringence is smaller than in the case where the beam direction is parallel to lamellas.

This is a preliminary study of the effect of vertical curvature on the cantilever and arch stresses in a double-curvature arch dam. A modification of the conventional method of crown cantilever is proposed with the consideration of the adjustment of vertical displacements, in additon to the radial displacements at the crown of arches. Results of the study indicate that, if the vertical curvature is properly chosen, tensional stresses in the crown cantilever of the dam can be reduced to a certain extent. Experimental...

This is a preliminary study of the effect of vertical curvature on the cantilever and arch stresses in a double-curvature arch dam. A modification of the conventional method of crown cantilever is proposed with the consideration of the adjustment of vertical displacements, in additon to the radial displacements at the crown of arches. Results of the study indicate that, if the vertical curvature is properly chosen, tensional stresses in the crown cantilever of the dam can be reduced to a certain extent. Experimental study had been made with the aid of gelatin models. Analysis of the results showed that, except in the vicinity of the top of the dam, the general trend of the distribution of arch and cantilever stresses agreed with that of computation within reasonable limits.

The dynamic behavior of an arch-gravity dam during earthquakes is determined by the gelatin-model dynamic test, gypsum-model dynamic test and the approximate analysis. These results are fairly comsistent. The appr- oximate analysis method proposed in this paper is to determine the dynamic behavior of the entire dam from the dynamic behaviors of some vertical cross sections. The natural frequencies, modal shapes and the stresses of the dam with reservoir full are determined in terms of those yolues with reservoir...

The dynamic behavior of an arch-gravity dam during earthquakes is determined by the gelatin-model dynamic test, gypsum-model dynamic test and the approximate analysis.

The appr- oximate analysis method proposed in this paper is to determine the dynamic behavior of the entire dam from the dynamic behaviors of some vertical cross sections. The natural frequencies, modal shapes and the stresses of the dam with reservoir full are determined in terms of those yolues with reservoir empty by the perturbation method.

The diameters and projection area of the articular surfaces, contributed to the formation of the sacroiliac joint, were determined on 50 sets of pelvic bones with image analysing apparatus.By drawing a line connecting the most anterior point of the prominence to the deepest point of the posterior incisure, the articular surface may be divided into a superior and an inferior portions. The inferior portion was larger than the superior portion. Each portion of the articular surface on the ilium is slightly larger...

The diameters and projection area of the articular surfaces, contributed to the formation of the sacroiliac joint, were determined on 50 sets of pelvic bones with image analysing apparatus.By drawing a line connecting the most anterior point of the prominence to the deepest point of the posterior incisure, the articular surface may be divided into a superior and an inferior portions. The inferior portion was larger than the superior portion. Each portion of the articular surface on the ilium is slightly larger than that on the sacrum.In order to explore the relationship between the form of the articular surface and its function in transmitting the gravity of the human body, the stress of the neighbouring area near the anterior margin of the articular surface was determined. Moreover, the bony architecture on the cross section passing through the articular surface was observed. It suggests that the strain in the neighbouring area was in linear equation with the gravity loaded on the spinal column. The strongest stress was determined at the anterior margin of the anterior prominence and the thickness of the cortex lying on the relevant bones appears most obvious at the same sites. These results further improve that the bony architecture was consistent with the strain in bearing the body weight. Besides, the form of the articular surface was also adapted to its function.

本研究应用图像分析仪,测定了50付髋骨与骶骨骶髂关节面的纵径、横径和投影面积。女性骶髂关节面宽而短,关节面上部面积大于男性;男性关节面狭而长,其下部面积大于女性。由于男性髂骨翼近乎垂直,女性接近水平,因而男性骶骨或髂骨关节面角大于女性;女性背侧凹陷更近于下端,这些变化与男、女性小骨盆腔和骨盆倾角的大小相适应,女性骨盆倾角大,关节面上都受力更集中。关节面形状,应力分布,骨质结构与重力传递有关。关节面前缘上部凸向前,而后缘则形成凹陷,应变值测试表明,隆突部应力最大,骨剖面显示隆突部骨密质最厚,骨小梁向隆突集中。上述变化与人体重力由第五腰椎经骶骨、两侧骶髂关节传递于下肢相适应。
