The present invention discloses a quasi-zero-stiffness (QZS) based six-degree-of-freedom (6-DOF) absolute displacement and attitude measurement device. A lower end coil and an upper end coil are respectively charged with currents in the opposite directions; The electromagnetic field and the magnetic fields of an upper magnet and a lower magnet per se are mutually acted to produce an electromagnetic stiffness opposite to the stiffness of a spring. The stiffness of the whole leg is close to zero stiffness. When the to-be-measured platform generates space motion, the reference platform is in the stationary state. At this point, the deformation amounts of the six legs can be measured by laser displacement sensors. The six deformation amounts are respectively inputted into the displacement and attitude resolver, and by forward kinematic solution of the 6-DOF device, the displacement and the attitude of the to-be-measured platform can be obtained.

A method for preparing potassium chloride from carnallite includes: carrying out high-temperature water solution mining treatment on carnallite with fresh water to obtain potassium-rich saturated brine; mixing the potassium-rich saturated brine, a sylvine saturated solution, and bittern for mixing brine, evaporation and decomposition to obtain artificial sylvine; and carrying out low-temperature selective dissolution treatment on the artificial sylvine with fresh water to prepare potassium chloride. The carnallite is mined by using hot water, which reduces the content of sodium chloride in the potassium-rich saturated brine; artificial sylvine is only subjected to low-temperature selective dissolution once, which avoids unnecessary energy consumption and impurity accumulation unnecessary for multifold cycles of thermal dissolution-cold crystallization treatment of sylvine while guaranteeing the high yield and high quality of potassium chloride. The method is suitable for different grades of carnallite, has extremely strong adaptability and loose technical conditions, and is conducive to promotion and implementation.
