Abstract: An ultrashort echo time (TE) magnetic resonance fingerprint relaxation time measuring method. Semi-pulse excitation and semi-projection readout are used to shorten a TE to achieve acquisition of an ultrashort T2 time signal; and image acquisition and reconstruction are based on a magnetic resonance fingerprinting technology. A TE change mode of sinusoidal fluctuation is introduced, improving the capability, of a magnetic resonance fingerprint signal, of distinguishing short T2 tissues from ultrashort T2 tissues, and realizing simultaneous multi-parameter quantitative imaging of the short T2 and ultrashort T2 tissues and long T2 tissues. The non-uniformity of a magnetic field is modulated into phase information of a fingerprint signal by means of the TE of the sinusoidal fluctuation, a B0 graph is directly reconstructed according to an amplitude modulation signal demodulation principle, and the phase change caused by a B0 field is compensated in the fingerprint signal, so as to improve the accuracy of signal recognition. In magnetic resonance skeletal muscle system imaging, simultaneous quantitative measurement of T1, T2, PD and B0 of the bone (ultrashort T2) and muscle (long T2) tissues can be realized; and said method can also be used for imaging the brain and measuring the grey/white matter relaxation time and the skull structure.

Abstract: A road network balanced drainage method and a road construction method aiming at reducing urban waterlogging. The road network balanced drainage method comprises steps of: determining a waterlogging road section at first, and determining whether an intersection at the upstream of the waterlogging road section meets flow distribution requirements, if so, performing elevation reconstruction on the intersection to cause the water flowing in the intersection to flow to a road other than the road where the waterlogging road section is located, and if not, tracing a water inflow road of the intersection to an upstream intersection to determine whether the upstream intersection meets the flow distribution requirements, until the intersection that meets the flow distribution requirements is found, and performing elevation reconstruction on the intersection. The road construction method is to change the topography of the intersection and the limited adjacent area thereof by means of elevation designs when constructing a road that intersects the waterlogging road section, so as to prevent or reduce flow of water to the waterlogging road section. The present method can be used not only for the technical reconstruction of existing intersections, but also for planning and designing roads to be constructed so as to effectively eliminate or prevent urban waterlogging.
