红景天皂甙对力竭运动大鼠血浆中支链氨基酸的影响

探讨中药红景天皂甙在力竭运动中对血浆中支链氨基酸的影响。运用运动训练学和运动生物化学方法对大鼠建立实验模型,采用阶段力竭游泳训练并将大鼠分为安静对照组、训练对照组、安静中药组、训练中药组。实验12天后取材,液相色谱法检测大鼠血浆中缬氨酸(Va1)、亮氨酸(Leu)、异亮氨酸(Ile)的浓度变化。结果发现,红景天皂甙在提高大鼠血浆支链氨基酸方面效果显著。在力竭运动测试中,血浆支链氨基酸对维持大脑中枢稳定、骨骼肌细胞再合成起到了重要的作用。     

Three—Dimensional Generalized Inverse Matrix Rational Interpolation

In this paper,a three-dimensional matrix valued rational interpolant(TGMRI) is first constructed by making use of the generalized inverse of matrices.The interpolants are of the Thiele-type branched continued fraction form,with matrix numerator and scalar denominator,Some properties of TGMRI are given.An efficient recusive algorthm is proposed.The results in the paper can be extend to n-variable.

Numerical simulation of a gas pipeline network using computational fluid dynamics simulators

This article describes numerical simulation of gas pipeline network operation using high-accuracy computational fluid dynamics (CFD) simulators of the modes of gas mixture transmission through long, multi-line pipeline systems (CFD-simulator). The approach used in CFD-simulators for modeling gas mixture transmission through long, branched, multi-section pipelines is based on tailoring the full system of fluid dynamics equations to conditions of unsteady, non-isothermal processes of the gas mixture flow. Identification, in a CFD-simulator, of safe parameters for gas transmission through compressor stations amounts to finding the interior points of admissible sets described by systems of nonlinear algebraic equalities and inequalities. Such systems of equalities and inequalities comprise a formal statement of technological, design, operational and other constraints to which operation of the network equipment is subject. To illustrate the practicability of the method of numerical simulation of a gas transmission network, we compare computation results and gas flow parameters measured on-site at the gas transmission enter-prise.
