Abstract: The present invention relates to a symmetrical dodecaphonic harmony notation system for 12 ET based music, abbreviated as SymD notation. One of the most predominant characteristics of SymD notation is a staff of 5 lines arranged symmetrically with 8 space settings between and beside the lines for all 12 semitones and its octave in a 12 ET scale. The staff serves as a visual reference for intervallic harmony relationships in sonority and melody progressions in 12 ET music.

Abstract: A nuclear reactor includes a reactor container, a reactor core, a control drum assembly, a hot channel, a heat exchanger and a main pump. The reactor container contains a coolant; the reactor core is arranged at a lower middle part of the reactor container; the control drum assembly is arranged on an outer periphery of the reactor core, and includes control drums arranged at intervals along a peripheral direction of the reactor core; the hot channel is arranged in the reactor container and located above the reactor core. The hot channel has a bottom hermetically connected to the control drum assembly and a top hermetically connected to an inner top surface of the reactor container. The hot channel has a hot pool passage for the coolant to pass through. The heat exchanger is arranged in the reactor container and located on an outer periphery of the hot channel.

Abstract: A passive containment heat removal system and a control method thereof are provided. The system includes an outer containment an inner containment disposed in the outer containment, an air duct formed between the inner containment and the outer containment having an air inlet and an air outlet; a spraying assembly disposed outside the inner containment and configured to passively spray cooling water to an outer wall of the inner containment to cool the inner containment; a built-in heat exchanger disposed in the inner containment; an air cooling channel having an air inlet of the air cooling channel and an air outlet of the air cooling channel; an external air cooler disposed in the air cooling channel with an inlet connected with an outlet of the built-in heat exchanger via a first communicating pipe and an outlet connected with an inlet of the built-in heat exchanger via a second communicating pipe.

Abstract: The present invention relates to braking torque detection for an elevator brake and belongs to the technical field of elevators. A braking torque detection method for an elevator brake according to the present invention comprises the following steps: a drive motor outputting a first detection torque for a first brake torque inspection; the drive motor stopping output of the detection torque in intermittent time periods when it is determined that a second brake torque inspection is required according to a result of the first brake torque inspection; and the drive motor outputting a second detection torque for the second brake torque inspection. The present invention can avoid overheating of a frequency converter in a continuous braking torque detection process and achieves good braking torque detection accuracy.

Abstract: This invention provides methods, apparatus and kits for the quantitative and qualitative characterization of the nucleic acid molecule's behavior by modify the nucleic acid molecules to incorporate selected fluorescent base analogues (FBAs). The methods generally place one or more fluorescent base analogue into a nucleic acid molecule (e.g., an oligonucleotide) to replace the corresponding normal base(s), arrange fluorescent base analogues as intrinsic fluorescent probes by using direct excitation, indirect excitation, and excimer emission labeling schemes, introducing so modified nucleic acid molecules into the matrix with interested condition and measuring the fluorescent properties of the modified nucleic acid molecules at the specific emission wavelength of FBA(s). The apparatus is designed to irradiate the FBA(s) incorporated nucleic acid molecule at a wavelength in the range of 240 nm-280 nm and detect the fluorescent activities at the specific emission wavelength of the respective FBA(s).
