The invention discloses a method for preventing a valve core position of an electronic expansion valve from offsetting and a corresponding protective cover. According to the method for preventing the valve core position of the electronic expansion valve from offsetting, a protective cover capable of generating magnetism is arranged at the exterior of a valve body of the electronic expansion valve, and the valve core position of the valve body is prevented from offsetting due to vibration in the transport process by using the magnetism generated by the protective cover and an interaction force generated by a magnetic rotor in the valve body. The transport protective cover of the electronic expansion valve comprises a protective cover main body capable of generating magnetism, and the protective cover main body is provided with a hollow cavity matched with a sleeve of the electronic expansion valve. The magnetic rotor positioned in the sleeve of the electronic expansion valve and the protective cover main body positioned at the outer end of the sleeve are mutually attracted. The protective cover main body capable of generating magnetism is arranged at the exterior of the electronic expansion valve, and the magnetic piece in the protective cover main body can be mutually attracted with the magnetic rotor of the electronic expansion valve to fix the valve core during transporting; and the protective cover has the advantages of simple structure, convenience in use and capability of being reused.

The invention discloses an electric corrosion preventing bearing, and relates to a bearing. Electric corrosion is easily produced due to potential difference between an inner ring and an outer ring of a rotating bearing, so the current flowing surface of the bearing is concavo-convex, and the service life of the bearing is shortened. The electric corrosion preventing bearing comprises an inner ring, an outer ring and a rolling body positioned between the inner ring and the outer ring. The electric corrosion preventing bearing is characterized in that: a conductive electric ring is arranged between the outer ring and the inner ring, the elastic ring is contacted with the outer ring and the inner ring, and the bearing is provided with a limiting part for positioning the elastic ring. The elastic ring keeps a contact state with the outer ring and the inner ring by means of elasticity; the bearing has simple structure and is easy to manufacture, so the bearing has low cost and is suitable for large-batch production; and the bearing has good reliability, and the voltage difference between the inner ring and the outer ring of the bearing is reduced to zero so that the service life of the bearing is prolonged.

The invention discloses an elastic imaging method and device for measuring anisotropic elastic properties of nerves. The method includes the following steps: allowing a subject to adopt a certain fixed body position, and keeping the body position stable; respectively placing an ultrasonic probe along a nerve fiber direction and a direction perpendicular to the nerve fiber direction; in the above two cases, emitting simulation to the nerves in a certain way; performing imaging on nerve fiber/nerve cross sections by using the ultrasonic probe at a certain pulse repetition frequency, and obtaining a particle velocity field by a signal processing process; and further obtaining nerve wave propagation in two cross sections, and analyzing the wave propagation signals to obtain results for characterizing anisotropy of the nerves to be tested. The method can characterize the anisotropic elastic properties of the superficial peripheral nerves with larger diameters in a non-destructive, non-invasive and quick manner, the measured parameters can quantitatively describe the anisotropy of the nerves, and early diagnosis of nerve-related diseases can be performed.
