The invention discloses a data behavior based low-energy consumption cluster storage replication device and method. The data behavior based low-energy consumption cluster storage replication device comprises a metadata server and a storage server. The storage server is composed of a hot node set and a cold node set. The data behavior based low-energy consumption cluster storage replication method includes that the hot node set is in a normally open state to store hot spot data frequently accessed by clients and provides QoS (quality of service) guarantee for a storage system; the cold node set stores cold spot data containing large amount of data and seldom accessed by the clients, automatically transfers into a dormant state in the absence of requests, and immediately switches back to a working state to process requests once arriving.

A warming gas flows through a jacket to heat an insufflation gas flowing in a separate tube, thereby reducing cost and disposable waste. The heated warming gas may be filtered to sterilize or maintain sterility and released to atmosphere after heating the flowing insufflation gas. Alternatively the warming gas may be reheated and recirculated through the jacket, with an additional tube being used within the jacket so that the warming gas flows in both directions lengthwise. The insufflation gas may be carbon dioxide and the warming gas may be room air. The heating element and sensors may be separate from the disposable unit of a heated insufflation set, and need not be re-sterilized prior to or after use in surgery. The heat is constantly maintained, thereby eliminating “cold spots” caused by the natural cycling of the resistance heaters due to the nature of the operation being preformed on the patient.

The invention provides a population genetic evolution map and a construction method thereof. The construction method comprises the following steps: selecting a recombined cold spot region; constructing a phylogenetic tree by utilizing the SNP sites of the recombined cold spot region; performing clustering analysis on the phylogenetic tree, and determining an evolution relationship between speciesso as to obtain a population genetic evolution map. According to the method, the phylogenetic tree is constructed by selecting SNP sites of the recombined cold spot region (such as a centromere region); on one hand, due to low recombination occurrence rate and stable inheritance between parents and filial generations, the genetic evolution relationship is clear, the constructed phylogenetic tree is more accurate, and on the other hand, the number of SNP sites in the selected sequence is smaller than that of whole genome sequences and is more and more comprehensive than that of SNP sites in a haplotype analysis method. Therefore, the phylogenetic tree can be quickly and accurately constructed.
