The invention discloses a preparation method and application of haemocoagulase of Agkistrodon akistrodon. It comprises steps of dissolving snake venom, low-temperature centrifugation, dialysis, DEAE-Sepharose FF chromatography, dialysis, DEAE-Sepharose FF chromatography and Sephadex G25 chromatography. It is isolated and purified from the venom of Agkistrodon akistrodon, which is unique to China. It is composed of two subunits, A and B, and has the effect of promoting blood coagulation and hemostasis. The molecular weights of the two subunits A and B are 15.0KD and 14.2KD. The amino acid sequence from the first to the 25th position of the N-terminal of the A subunit is DCSSGWSSYEGHCYKVFKQSKTWTA, and the amino acid sequence from the first to the 25th position of the N-terminal of the B subunit is DCPSDWSSYECHCYKPDEPKTWEDA. Agkistrodon haemocoagulase can be used for clinical hemostasis of various types of bleeding in humans.

The invention discloses a mining machine fast frequency search method and device as well as the mining machine. The method includes: under the initial output voltage of the power supply of the mining machine, the frequency of the computing chip is gradually increased from the initial frequency point through at least one first frequency point to the target frequency, wherein the duration of the operation chip at each first frequency point is shorter than the duration of the operation chip at each first frequency point in the conventional frequency search process; when the operation chip reaches the target frequency, according to at least An output voltage value and at least one second frequency point, combined with the test tasks issued to the computing chip and the feedback results of the computing chip, the output voltage of the power supply of the mining machine and the frequency of the computing chip are adjusted to obtain the limit frequency of the computing chip and The output voltage of the mining machine power supply corresponding to the limit frequency. The present invention shortens a large amount of frequency search time, saves power consumption of frequency search, and the saved time is used for mining calculation of mining machines to further improve mining efficiency.

The invention discloses an automobile with a defecating chair. At least one chair in the automobile is the defecating chair. The automobile is provided with a passenger car privacy protecting system.The automobile with the defecating chair has the advantages that the automobile is convenient to use and safe and sanitary, has a relatively good private function, and is high in degree of intelligence. The chair with a bed pan mounted in the automobile still retains the function of the chair, and the quantity of chairs is not affected.

The invention provides a method and a system for improving the reliability of a service in a passive optical network (PON) system. User network interfaces (UNI) of two optical network units (ONU) are connected, a flexible link protocol group and a monitoring link protocol group are configured on the two ONUs respectively, and the mutual backup of the two ONUs is realized in a way of fitting special mechanisms of the flexible link protocol group and the monitoring link protocol group. By the method and the system, link backup protection between optical line terminals (OLT) and the ONUs can be realized by adopting ordinary single-PON port ONUs, and the number of actual accessing ONUs under the OLT is not influenced.
