Disclosed are a high-strength steel bar and a production method therefor. The high-strength steel bar comprises, by mass percentage, the following chemical components: C: 0.15-0.32%, Si+Mn: 0.5-1.9%, Mn+Cr+Mo+Ni: 1.1-2.1%, V: 0.02-0.8%, at least one of Nb, Ti and Al: 0.01-0.3%, and the balance of Fe and inevitable impurities; wherein Mn=(2.5-3.5)Si, and a carbon equivalent satisfies Ceq=C+Mn/6+(Cr+Mo+V)/5+(Cu+Ni)/15≤0.56%.

High-strength steel bar and production method thereof

A gradient coil assembly of a magnetic resonance imaging system includes at least one gradient coil, a cooling arrangement for cooling the gradient coil, and an RF shield. The cooling arrangement includes at least one cooling tube that is configured to transport a cooling fluid and which is disposed on and in thermal contact with the gradient coil, wherein the assembly further comprises a thermal connector arrangement with at least one of a first thermal connector disposed between the RF shield and the at least one cooling tube, which provides a radially extending connection between the RF shield and the at least one cooling tube.

Cooling a gradient coil of a magnetic resonance imaging system

A gradient coil assembly () for use in a Magnetic Resonance Imaging (MRI) system includes primary coils (), shield coils () and a supporting structure () arranged between the primary coils () and the shield coils (). The supporting structure () includes at least a supporting element () including a first end face () and at least a first recess () with an opening () in the first end face (). The first recess () extends in a longitudinal direction () of the supporting element () forming a tray for receiving a passive shim bar.

A method for making a color image and a color filter manufactured with the method. The color of the color image and the color of the color filter are characterized by resonance features of a Fabry-Perot resonant cavity (). Through a nanoimprint technology, Fabry-Perot resonant cavities with different thicknesses are manufactured, and the Fabry-Perot resonant cavities with different thicknesses correspond to red, green and blue respectively. The red, green and blue Fabry-Perot resonant cavities are distributed according to the color separation principle, and a combination thereof has the effect of representing a whole image macroscopically.
