教育产业化若干问题的思考

教育产业化的理论和实践探讨在我国刚刚兴起 ,所以对教育产业化的界定还没有统一的定论。基于此 ,本文提出了教育产业化应是教育全过程产业化的观点 ,同时 ,探讨了教育产业化的根本原因、基本特征、客观必然性、基本条件和可操作性策略     

基于神经网络的管件开式冷挤压相对伸长量预测

为了预测各参数组合下的无芯棒开式冷挤压厚壁管件的伸长量，拓展开式冷挤压的实验结果，建立了无芯棒开式冷挤压厚壁管件的伸长量预测的神经网络模型，通过实验结果与预测结果的比较，二者吻合良好，为深入研究开式冷挤压工艺，建立开式冷挤压工艺设计专家系统提供了新的思路。     

Development of NiTiNb in-situ composite with high damping capacity and high yield strength

The shape memory alloys are well known to exhibit high damping capacity in martensite state,but possess low yield strength because of the reorientation or de-twining of the martensite variants.The high damping mechanism of shape memory alloys was introduced.The NiTiNb alloys with high yield strength and high damping capacity were designed and prepared.The microstructure evolution,martensitic transformation behavior,damping capacity and mechanical properties of series NiTiNb alloys were investigated.In vi...     

Effects of particle size on the mechanical properties of particle-reinforced Sn-Ag composite solder joint

Particulate size has significant influenced on the mechanical properties of particle-reinforced composite solder joints.In this current research,Cu or Ni reinforcement particles were mechanically added to the Sn-3.5Ag eutectic solder,and the effects of the particle size on the mechanical properties of particle-reinforced composite solder joint were systematically studied. This investigation touched on how mechanical properties of the solder joints are affected by particles size.A quantitative formula was se...     

A new 3-D Gd–Cu heterometallic polymer [Gd_2Cu_3(bpy)_2-(ip)_6]·6H_2O with a non-interpenetrated α-Po net

A new 3-D porous Gd-Cu heterometallic polymer [Gd2Cu3(bpy)2(ip)6]·6H2O (1) (bpy = 2,2'-bipyridine, H2ip = isophthalic acid) has been hydrothermally synthesized and structurally characterized. Compound 1 crystallizes in the triclinic space group P1and displays a 3-D non-interpenetrated α-Po network with 1-D channels filled transversely by the hexa-nuclear chain-like (H2O)6. The EPR and thermal stability of 1 were investigated.

Numerical Simulation of the Morphology and Moving Velocity for Electrospun Stable Jet

GAMBIT,POLYFLOW and FLUENT POST were used to simulate the morphology and the velocity of electrospun stable jet.Simulation results shows that jet diameter decreases with the increased draw force acted on the stable jet.But too great draw force would lead to thick knots appearing along the jet or stable jet disappearing during electrospinning.There is a linear relationship between the velocity and the moving distance.But the linear relationship does not exist under great draw force.
