This invention discloses a data buffer storing method and a system under cluster environment, in which, the method includes: a customer end sends a data calling request, a server enquires if there are data to be called in the loca buffer storage, if not, it enquires the database, if so, it judges if the buffer storage data are invalid, if not, it returns the data result to the customer end directly, if so, it enquires the database to return the result to the customer end and writes it in the buffer storage, therefore, it guarantees that the data result to the customer end by the server is the newest and the method will not break the character of cluster technology.

A power transmission control apparatus is a power transmission control apparatus provided in a power transmission apparatus included in a contactless power transmission system where power is transmitted from the power transmission apparatus to a power reception apparatus by electromagnetically coupling a primary coil and a secondary coil. The power transmission control apparatus includes: a signal detection circuit that detects a signal induced by the primary coil; and a power transmission control circuit that determines a value of transmission data transmitted from the power reception apparatus by a load modulation, on the basis of an output signal of the signal detection circuit. The power transmission control circuit obtains detection data by detecting the transmission data on the basis of the output signal of the signal detection circuit at every drive clock cycle of the primary coil. If a value of the detection value is identical n-times continuously, where n=m+α≦p, the m is an integer equal to or larger than 0, the α is an integer equal to or larger than 1, and the p is an integer equal to or larger than 1, the power transmission control circuit determines that the value of the transmission data transmitted by the power reception apparatus is the value of the detection data.

The method for a hydrocarbon mixture composition determination includes the collection of at least one sample of the hydrocarbon mixture. For this sample, a nuclear magnetic resonance method is used for measuring series of hydrocarbon mixture's free inductance decrement curves within a temperature range of −150° C. to +150°. Each free inductance decrement curve is then used to determine the solid component fraction Ps in the NMR 1H signal at a temperature, at which this value was measured. The received values are then used to plot a temperature dependence of the solid component fraction Ps in the NMR 1H signal and, based on the Ps value variation (ΔPsi), caused by a phase transition of the ith component due to a heating or cooling process and the content of solid and / or liquid phase components in the hydrocarbon mixture is defined by attributing the ΔPsi value to the associated components of the mixture.
