The thymus of grass carp is situated on either side of the upper corner of the opercular cavity. It lies closely under the membrance of the opercular cavity. The projecting part of the thymus is protracted into the subtemporal hollow. The shape of the total thymus is similar to that of water chestnut. The thymus of grass carp consists of the outer, middle, and inner regions. The middle and inner regions consist chiefly of lymphocytes and reticuloepithelial cells, whose structural features are similar to...

The thymus of grass carp is situated on either side of the upper corner of the opercular cavity. It lies closely under the membrance of the opercular cavity. The projecting part of the thymus is protracted into the subtemporal hollow. The shape of the total thymus is similar to that of water chestnut. The thymus of grass carp consists of the outer, middle, and inner regions. The middle and inner regions consist chiefly of lymphocytes and reticuloepithelial cells, whose structural features are similar to those of the cortex and medullary region of the higher vertebrates respectively. There is no abvious demarcation between middle and inner regions. There are three types of lymphocytes in thpmus: large (4%), medium (18%) and small lymphocytes (78%). The number of thymus lymphocytes is approximately 3.6×10~6 cells per milligram in oneyear-old fish, and 2×10~6 cells per mg in two-year-old grass carp. In one and two year old grass carp total weight of the thymus increased with age, but in bigger fish thymus weight does not change in a regular way. Adult fish show apparent degeneration in thymus. The thymus of grass carp also shows age-independent degeneration caused by nutritional and enviromental factors.

草鱼胸腺位于鳃腔背上角,紧贴在鳃腔膜之下,突起部分伸入到下颞凹,整个胸腺形态形似菱角。其组织结构可分为外区、中区和内区。中区和内区主要由淋巴细胞和网状上皮细胞构成,在组织结构上分别类似于高等脊椎动物胸腺的皮质和髓质区。胸腺淋巴细胞可分大、中、小三型,小淋巴细胞约占78%,中淋巴细胞约占15%,大淋巴细胞约占4%。在Ⅰ龄草鱼,每毫克胸腺约有3.6×10~6个胸腺淋巴细胞,Ⅱ龄草鱼约为2×10~6。Ⅰ至Ⅱ龄草鱼胸腺重量明显地随鱼龄增加,Ⅱ龄以上草鱼胸腺重量变化无规律,成鱼胸腺表现出明显的退化。草鱼胸腺除年龄性退化外,还存在环境因素引起的非年龄性退化。

The sealing elements in an oil well packer are made of elastomeric materials with non-linear geometry and material behavior.The non-linear relation of the materials is generally expressed in terms of a deformation tensor with three invariants of in this paper, on the basis of the principle of stationary potential energy and total Lagrange formalation, an incremental non-linear mixed finite element formulations of large displacement and large strain have been developed for elastomeric materials .Four-node quadrilateral isopa rametric ring elements are used to analyze an infinitely long thick-walled cylinder subjected to internal pressure. The computed results agree very closely with the exact solution, and the procedure is effective and reliable. The computations of the displacements, stresses and contact pressures are given which shows that: (1) the sealed tube is compressed on the external wall in the upper corner to turn upwards gradually; (2) the stresses in the sealed tube are basically compressible; (3) there are certain contact pressures on the internal wall and external wall of the sealing elements .The findings are useful for the rational design of the elastomeric sealing elements.

油井封隔器胶筒是由橡胶类材料制成的。橡胶类材料构件的几何形态和材料性能都是非线性的,材料的非线性关系一般用三个变形张量不变量表述。本文基于势能驻值原理,采用整体Lagrange法,建立适用于橡胶类材料的大位移和大应变的增量形式的非线性有限元混合法的计算列式。用四结点四边形等参数环元,对受均匀内压无限大厚壁圆筒进行计算,其结果与精确解符合很好,表明这种方法是有效和可靠的。油井封隔器胶筒的位移、应力和接触压力的计算结果表明:(1)胶筒外壁的上角部位有被挤上翘的趋势,(2)胶筒内的应力基本上是受压的,(3)胶筒的内外壁都有一定的接触压力,计算方法为合理设计封隔器胶筒提供了理论基础。

Thoracic and lumbar spinal injury comlicated the spinal cord compression was mainly caused by displaced vertebral body fragment, posterior--upper corner of the vertebral body and protrused disc. Over 20 degree of posterior bending angle in dorsal and lumbar spine uaually resulted in- spinal stenosis and caused spinal cord compression. Those are indication for anterior--lateral decmpression. The advantages of pre--Pedicel anterior--lateral decom- prssion throuth posterior midline approach are less trauma,...

Thoracic and lumbar spinal injury comlicated the spinal cord compression was mainly caused by displaced vertebral body fragment, posterior--upper corner of the vertebral body and protrused disc. Over 20 degree of posterior bending angle in dorsal and lumbar spine uaually resulted in- spinal stenosis and caused spinal cord compression. Those are indication for anterior--lateral decmpression. The advantages of pre--Pedicel anterior--lateral decom- prssion throuth posterior midline approach are less trauma, the easy exploration of spinal cord and instrumentation of posterior fixator. Yet, indirect vision to the front of the spinal cord, and sometimes inadequate decompression of the opposite side or decomression of opposite side, were the disadvantages. This treatment could be appllied to injuries above T10 thoracic below L2 lumbar vertebrae. It is also indicated in injuries in dorso-lumbar region.

胸腰椎骨折脱位并截瘫主要系椎管前方的椎体骨拆块、椎体后上角与椎间盘突出及大于20°的脊柱后弓成角所致,是侧前方减压的适应证。经后正中入路椎弓根侧前方减压的优点是手术创伤较小,可同时探查脊髓与安置后方内固定;缺点是不能直视脊髓前方,对侧减压可能不彻底或需对侧辅助减压。适于T10以上的胸椎与L2以下腰椎,亦适于胸腰段,特别是已行椎板切除者。
