This paper investigates the general and complete form of slope-deflection equations used in structural analysis. The word "complete" indicates that all the possible deformations (deflections and rotations) and all the strain energies (due to shear, direct stress and flexure) are included in the equations. The definitions, numbers, and relations of member constants are then discussed and the general equations for computing these constants are given. By neglecting the factors of minor importance, the general...

This paper investigates the general and complete form of slope-deflection equations used in structural analysis. The word "complete" indicates that all the possible deformations (deflections and rotations) and all the strain energies (due to shear, direct stress and flexure) are included in the equations. The definitions, numbers, and relations of member constants are then discussed and the general equations for computing these constants are given. By neglecting the factors of minor importance, the general form is reduced to the usual slope-deflection equations. Some special forms of such equations which are useful in certain practical problems are also discussed briefly, such as the slope-deflection equations including the effect of direct stress on flexure and the slope-deflection equations of semi-rigid frames. Slope deflection equations for trussed bents are also presented.

本文旨在:(1)提出完全的角变位移方程,使可精确的解算任何形式的平面刚构,只要其能视为由若干桿件组成即可。这里的所谓“完全”,系指方程中已包括一切可能的形变值在内,而且包括轴向应力及剪应力之影响。(2)全面的讨论桿件常数的定义、数量和相互关系,并供给计算各常数的最一般性公式。(3)将上述全面的和精确的公式逐步简化,以便与目前常用的公式比较。(4)讨论某些特殊情况。

A new species of tapeworm Bothriocephalus gowkongensis sp. nov. is reported for Ctenopharyngodon idellus from Gowkong, near Canton, South China. The parasite is of great economic importance owing to the high mortality of the host caused by the infection and consequently heavy losses to the freshwater fishery industry. A preliminary note is given on the life cycle, which involves unidentified cyclops as intermediate hosts. The eggs are fully embryonated when laid and it is the first Bothriocephalus konwn...

A new species of tapeworm Bothriocephalus gowkongensis sp. nov. is reported for Ctenopharyngodon idellus from Gowkong, near Canton, South China. The parasite is of great economic importance owing to the high mortality of the host caused by the infection and consequently heavy losses to the freshwater fishery industry. A preliminary note is given on the life cycle, which involves unidentified cyclops as intermediate hosts. The eggs are fully embryonated when laid and it is the first Bothriocephalus konwn with this phenomenon. From a study of the variation in a large number of specimens of B. gowkongensis sp. nov., the author considers B. opsariichthydis Yamaguti, 1934 a synonym of B. achilognathi Yamaguti, 1934.SPECIFIC DIAGNOSIS: Bothriocephalus Rudolphi, 1808 emended Lühe, 1899, with generic characters. About 35-80 mm. in length and 0.5-1.2 mm. in width. Segments with or without distinct segmentation. Slight indications of secondary segmentation might occur in all segments. Immature segments broader than long, mature segments square and gravid segments longer than broad. Scolex large, fleshy, heart-shaped with distinct terminal disc and well-developed fleshy bothria. Inner longitudinal muscle bundles extremely weak and sparsely scattered. 50-90 testes. Cirrus immediately in front of vagina. Cirro-vaginal aperture median or slightly lateral between mid-line and posterior third of segment. Ovary near posterior of proglottid. Uterus convoluted, voluminous, and confined to median field. Uterine sac-may encroach on posterior border of preceeding segment or be placed some distance away. Vitellaria in complete circle in cortex. Like the testes, they are continuous from segment to segment. Eggs thin-shelled, operculated, fully embryonated when laid, measuring 33-38 53-54μType host: Ctenopharyngodon idellus.Habitat: Intestine.Type: To be deposited with the Department of Parasitology, Hun-Nan Medical College, Canton, China.Co-types: In author's collection, and to be deposited with the Depertment of Biology, Chung-Shan University, Canton, China.

1.文中记载草鱼腸中新种絛蟲B. gowkongensisn. sp. 是由广东九江採得的。 2.本蟲促使宿主的死亡率,使淡水渔业受到很大的损失。 3.由头槽絛蟲生活史的初步观察,发现它的卵排出时,已有发育完全的胚胎。 4.从研究大量新种标本的变化中,作者认为B. opsariichthydis Yamaguti, 1934是B. achilognathi Yamaguti, 1934的同种异名。
