With the advantages of high torque and low noise, traction drive continuously variable transmissions (TDCVTs) have a promising application in future vehicles. However, their efficiency is limited by spin losses caused different speed distributions between contact areas traction. To overcome this shortcoming, paper proposes novel zero-spin design methodology applicable to any type TDCVTs. The analyzes features TDCVTs terms variation position shifting motion components. It also establishes...
The advent of the post-pandemic era, with its risks, uncertainties, and global characteristics, puts forward urgent requirements for innovation information literacy education in universities. Critical has become top priority education. It is to explore diversified effective critical strategies university students. This paper mainly expounds educational literacy, such as original material analysis, reflection, reading.
Two high performance silicon drift detectors (SDD) are installed at the equatorial port with z = 0 and -16.4 cm on HL-2A tokamak, respectively These SDDs combine new non-conventional software pulse height analyser (SPHA) successfully developed more recently by us to measure time evolution of soft x-rays spectra, thermal superthermal electron temperatures. The high-quality three-dimensional figure for energy spectra is easily obtained combination a SPHA computer. Therefore, measurement...
