    摘要： An integrated microfluidic device and its usage are provided. The microfluidic device comprises an upper layer (1) and a lower layer (2), wherein the lower layer (2) is bound to the upper layer (1). The upper layer (1) comprises a micro-channel (3) and the lower layer (2) comprises a micro-well (7) array. The micro-channel (3) is in fluidic connection with the micro-well (7) array, and the height of the micro-channel (3) is greater than the diameter of the oocyte (4) flowing through the micro-channel (3). The integrated microfluidic device has many advantages including low cost, high integration, and convenient operation, and has application prospects in reproductive medicine and the research of fertilization and embryo early development.

    摘要： Embodiments of the present invention disclose a lens module and its temperature-compensating method. The lens module primarily includes several lenses and a compensating lens. The several lenses comprise two plastic lenses and the ratio of the focal length of one plastic lens to the other is predetermined. The temperature-compensating method employs the compensating lens to shift alone an optical axis for compensation of the focal length departure. In one embodiment, the ratio of the two focal lengths is more than or equal to 0.5 and less than or equal to 2.

    摘要： A color wheel of a projector includes a red segment, a green segment, a blue segment and a white segment. The white segment is coated so as to provide color temperature of 6500K or 7000K. The red, green and blue segments are coated so as to provide full-segment transmission. The area ratio of the red segment, the green segment and the blue segment on the color wheel is designed based on the color temperature of the color wheel, so that color coordinate deviations can be reduced.

    摘要： A vibration squeeze drum washing machine structure; a vibration squeeze device (5) is provided at the inner side of a machine door (4) of the drum washing machine, a turnover mechanism (6) located below the machine door (4) mechanically connects the vibration squeeze device (5) to the machine door (4) such that the vibration squeeze device (5) can be turned up and down by 90 degrees at the inner side of the machine door (4); when being at an upturning position, the vibration squeeze device (5) is parallel to the door plane, when being at a downturning position, the vibration squeeze device (5) is at a right angle of 90 degrees to the door plane, and the vibration squeeze device (5) stretches underneath the drum (3). A mechanical vibrator (7) is installed in the inner cavity of the vibration squeeze device (5), when the vibration squeeze device (5) downturns to stretch into the drum (3) and start the mechanical vibrator (7), the vibration squeeze device (5) forms a vibration squeeze washing effect on the laundry in the drum (3). This vibration squeeze drum washing machine structure may significantly reduce the washing time of the drum washing machine, and has a better cleanliness and a better energy-saving environmental protection effect.
