Abstract: A microbial strain of Lachnospiraceae is a species of a genus of the family Lachnospiraceae (Lachnospiraceae sp.). The nucleotide sequence of 16S rRNA of the microbial strain of Lachnospiraceae is as shown in SEQ ID No. 1. The intestinal anaerobic microbial strain Lachnospiraceae sp. can inhibit the growth rate of tumors and can be used for preventing and/or treating tumors. The tumors include at least one of liver cancer, colon cancer, rectal cancer, colorectal cancer, lung cancer, breast cancer, cervical cancer, ovarian cancer, pancreatic cancer, cholangiocarcinoma, kidney cancer, and fibrosarcoma.

Abstract: A method for locking repetition rate of an optical frequency comb is provided. A cavity length adjusting actuator is adopted to lock the repetition rate of the optical frequency comb. When a locking state of the cavity length adjusting actuator is in a critical threshold state, an optical delay line of an optical frequency comb optical system is adjusted to adjust the repetition rate of the optical frequency comb, so as to keep locking the repetition rate of the optical frequency comb. A locking device of the repetition rate is also provided, in which an optical delay line control system can judge the locking state of a cavity length adjusting actuator control system in real time, such that the repetition rate can be slowly adjusted within a wide range, and the locking state of the optical frequency comb can be maintained.

Abstract: The application discloses a hard-shell flexibly-packaged capacitor module and a system, including: a flexibly-packaged individual capacitor and fastening plates, including a first fastening plate and a second fastening plate being oppositely mounted and connected in clasped manner; and, supports including a first support and a second support being oppositely mounted and used for connecting the individual positive and negative tabs respectively; and the two supports and the two fastening plates being enclosed to form a closed structure for accommodating the individual capacitor. Individual capacitors and a silica gel insulator are assembled inside the fastening plates clasped with each other, i.e. a “hard-shell” structure is provided for the individual capacitors; the hard-shell flexibly-packaged capacitor module is assembled as a whole, and multiple capacitor modules are connected in series or in parallel to form a required capacitor system, it is good in expansibility and easy to assemble.
