This paper used the method of distributive parameter's dynamic in [1]、[2] to calculate the phase-to-phase stress of conductive line in short circuit condition(i. e. dynamic stability) . This method strictly according to the facts that conductive line as a thin beam, it's quality elasticity, resistance all was distribution. Therefore, it could depite the dynamic feature of conductive line more precisely In [3] one considered many step、elastic constrain、 inner-resistance ( inner friction of Aluminium material)、 extra-resistance ( atmospheric resistance ) e. t.al. This paper considers a horizontal stress based on [3], may calculate stress of dynamic state and inverse stress of dynamic state of fulcrum.The mathematical problem, which was depicting above physical problem, was a partial differential equation of parabolic type in five orders. This paper get a numerical solution that could use difference method. Numerical results shows: when the conductive line in short circuit condition was increasing a little horizontal stress, ( constract with other quatity), the numerical results only has a little shift.This paper also analyze the computational stability condition of explicit difference schme. It's results shows: when increasing a horizontal stress, the computational stability condition as same as before.

本文采用[1]、[2]中提出的分布参数动力法来计算短路时母线相间应力(即动稳定)。此法如实的把母线看做质量、弹性、阻尼都是分布的樑,因而能更正确地反映母线的动态特性。[3]中考虑了多跨、弹性支持、内阻尼(铝材内部摩擦)、外阻尼(空气阻力)等因素。本文在[3]的基础上又多考虑了一项水平拉力的作用,可同时算出母线的动应力和动态支点反力。 描述上述物理问题的数学模型为一五阶抛物型方程。本文采用有限差分法进行数值求解。计算结果表明:加上一不大的水平拉力后(和其它物理量比较而言),对计算结果影响不大。文中还对显示格式的计算稳定性条件进行了推导。结果表明:加上水平拉力后,计算稳定性的要求不变。

The absorption and distribution of phosphorus in Cymbidium sinense(Andr.)Willdcultured in radioactive phosphorus(NaH2 32PO4)solution were studied.The absorbing abilityof 1-year-old root was stronger than that of 2-year-old root,but the latter still hadrather strong absorption ability, hence good care should be taken in both kinds of rootduring cultivation process.The sequence of accumulation of radioactive phosphorus(cpm/100mgDW) in vegetative groWth period was leaf bud, pseudocorm and leaf, but in reproductive...

The absorption and distribution of phosphorus in Cymbidium sinense(Andr.)Willdcultured in radioactive phosphorus(NaH2 32PO4)solution were studied.The absorbing abilityof 1-year-old root was stronger than that of 2-year-old root,but the latter still hadrather strong absorption ability, hence good care should be taken in both kinds of rootduring cultivation process.The sequence of accumulation of radioactive phosphorus(cpm/100mgDW) in vegetative groWth period was leaf bud, pseudocorm and leaf, but in reproductive growth period was floral bud, pseudocorm and leaf. This phenomenon coincideswith the rule that nutrient should distribute towards the growth center of plant.

钢管混凝土中钢管和混凝土能否共同工作是很多研究工作者关心的问题。国内外很多人对加强钢管与核心混凝土之间的结合,保证在轴向荷载作用下能共同工作进行了研究。有的还作了混凝土推出试验,测定混凝土与钢管间的粘结力;有的在管内加栓钉以增强二者的结合和整体性,尤其是在和梁连接的节点部位;有的还提出把钢管内壁作成花纹状以增加与混凝土的结合等等。 作者从荷载作用方式、钢管与混凝土的内力分布、梁连接处剪力的传递,以及截面的抗弯刚度等方面进行了分析,认为:保证核心混凝土密实和构件二端加盖板焊接密封是二者共同工作的关键,并不需要采用其它措施。
