  • Method for determining turbidity point and free carbohydrate buffer coefficient of iron-carbohydrate complex
    Patent number: 8679851
    Abstract: A method for determining a turbidity point and a free carbohydrate buffer coefficient of an iron-carbohydrate complex. The method includes: (1) contacting the complex with an acid; (2) determining hydrogen ion concentrations and solution turbidities of the complex in acid degradation; and (3) mathematically fitting the data, to obtain the turbidity point of the complex and the free carbohydrate buffer coefficient through mathematical treatment. A method for evaluating the safety of the iron-carbohydrate complex with the turbidity point and the free carbohydrate buffer coefficient.

  • Integrated ocean bottom towed array for four-component seismic data acquisition
    Patent number: 6607050
    Abstract: An integrated ocean bottom towed four-component array for seismic data acquisition consists of a four-channel electronic section for seismic data collection, a gimbaled three-component geophone and a hydrophone in a housing. The array connects with a submarine cable through a cable joint in order to acquire four components of data consisting of seismic P wave, shear wave and hydrophone in total. Through cable data transmission and processing in a central station, ocean bottom oil and gas structure information can be obtained. Because of the high SNR acquisition in the ocean bottom seismic data acquisition of the present invention, and the waterproof cable interconnections between each of the sections of the present apparatus, data acquisition of high quality can be gained to realize highly efficient and easy ocean bottom towing operations.
