The invention relates to the field of animal husbandry molecular breeding and precise breeding, in particular to an animal husbandry improved variety breeding twin-fetal cattle system based on gene screening. The system comprises an ovulation potential typing module, a uterine bearing capacity quantification module, a sex compatibility verification module and a decision module. Constructing a combined evaluation model of the double-ovulation basis and the uterus metabolism capability by systematically integrating site specific amplification and gene expression quantification technologies; the core of the method is that a precise reproduction instruction is generated according to full-link data of genotypes and phenotypes; according to the method, a single ovulation rate screening mode is changed, the problem of abortion and weak abortion caused by insufficient intrauterine environment is effectively solved, and the success rate of double-fetal pregnancy is remarkably increased.

The application provides a suspended optical mechanical system, comprising a first substrate block, a suspended waveguide, a suspended support beam, a plurality of support tether groups, a suspended detection mass and an optical cavity, wherein the suspended waveguide comprises a linear main body part extending along an X direction and a plurality of connection parts arranged in sequence and at intervals along the X direction, and the support tether groups are connected to the section of the suspended waveguide with the connection parts, the stability of the connection of the support tether and the suspended waveguide is increased, the width of the suspended waveguide at the connection parts is enlarged, the optical mode can be well limited in the waveguide, and the influence of the support tether on the optical mode is minimized. The tapered part of the connection part ensures the singularity of the mode in the process of light field transmission and slows down the change trend of the width of the suspended waveguide, which is beneficial to reduce the scattering loss and further increase the quality factor. The connection part arranged on one side can ensure that the gap width between the suspended waveguide and the optical cavity is constant, thereby ensuring the optimal coupling efficiency.

The utility model relates to a sealing detection device for an automobile headlamp, which belongs to the field of automobile headlamp detection and comprises a detection box body, a pressure sensor fixedly communicated with the inside of the detection box body and extending to the outside of the detection box body, a stand column fixedly connected to the top of the detection box body and a mounting plate fixedly connected to the top end of the stand column. A limiting mechanism for limiting and fixing the headlamp is arranged on the upper surface of the detection box body, and a negative pressure generation structure is arranged outside the detection box body. According to the sealing performance detection device of the automobile headlamp, the output end of the electric push rod drives the partition plate to move downwards in the detection box body to limit and fix the headlamp, the partition plate is connected with the linkage structure through the fixing rod and the rack, so that the piston plate is driven to reciprocate through the rotating disc and the connecting rod, and a negative pressure environment is formed in the detection box body; the risk of damage to the internal structure and the sealing material of the headlamp due to overlarge internal pressure is fundamentally eliminated, and the advantage of nondestructive testing is achieved.
