The solidification characteristics of Tb0.27Dy0.73Fex(x=1.8,1.95at%) alloy, as a giant magnetostrictive material, are studied with a super high temperature gradient directional solidification equipment developed by the authors.
Under the same steel tubular wall thickness and steel strength,the cost of the ultra-high strength concrete filled-steel tubular columns with the 116MPa strength lessens than that of the steel tubular concrete with 30 MPa,54MPa and 83MPa by 30.3%,18.7% and 11.5% respectively,and the cross section area of them decreases by 54.9%,38.8% and 21.5% respectively.
Numerical results show that low-speed maglev vehicle can negotiate safely the 300 m radius curve at a speed of 60 km·h~(-1), and can pass through smoothly the 1 100 m radius curve without superelevation at a speed of 90 km·h~(-1).
Dynamic analyses of steel-reinforced super high-strength concrete columns
The dynamic behaviors of steel-reinforced super high-strength concrete columns under seismic loading were studied with a series of experiments.
The super high sensitivity of the phase of the low-frequency wave to variations in the spatial position of the scatterer is used to measure the velocity of the object.
Relationship between leaf photosynthetic function at grain filling stage and yield in super high-yielding hybrid rice (Oryza sat
The characteristics of dry matter production before and after heading and the relationships between photosynthesis of flag leaves and dry matter accumulation in panicles were investigated on super high-yielding rice cv.
In addition, superelevation is apparent at each of the six bends along the proximal channel section.
Superelevation results from banking of the lava as it moves around the bend thus causing preferential construction of the outer bank.
Analysis of superelevation indicates flow velocities of ~8?m s-1.
Our analysis of the superelevation features is based on an inertia-gravity balance, which we show is appropriate, even though the down-channel flow is in laminar flow.
We use a viscosity-gravity balance model, together with the velocities calculated from superelevation, to obtain viscosities in the range 25-60?Pa s (assuming that the lava behaved as a Newtonian liquid).
