The invention belongs to the technical field of materials and discloses chiral mesoporous carbon nanometer fiber and a preparation method of the chiral mesoporous carbon nanometer fiber. The method is characterized in that pyrrole is used as an organic monomer, ammonium persulfate or ferric trichloride is used as oxidants, chiral amphipathic molecule N-myristoyl L-glutamic acid is used as a template, a chiral mesoporous carbon nanometer fiber precursor is synthesized by a chiral template molecule self-assembly induction method, and then, the chiral mesoporous carbon fiber is obtained through high-temperature carbonization in the inert atmosphere. The chiral mesoporous carbon fiber prepared by the method has the uniform and consistent spiral shape, meanwhile, a chiral mesoporous passage exists in the fiber axis center, the mesoporous passage size is 10.7 to 17.7nm, the specific surface area is 38 to 277 m<2> / g, the total pore volume is 0.09 to 0.38 cm<3> / g, in addition, rich nitrogen heteroatom is contained on a fiber wall carbon framework, and the nitrogen element content is 4.6 to 17.5 weight percent.

The invention discloses an aircraft oxygen system leak detection agent and a preparation method thereof, wherein the aircraft oxygen system leak detection agent comprises: 0.2-0.3% sodium myristoyl isethionate, 0.05-0.1% % of tea saponin, 0.05-0.1% of foam stabilizing and corrosion inhibiting aid, and the balance is deionized water. The foam stabilizing and corrosion inhibiting aid has alkenyl, amido, hydroxyl, ≡ A variety of functional groups of N→O group, among which, amide group and ≡N→O group are hydrophilic, which makes it have the foaming and foam stabilizing effect of surfactant, and can enhance the performance of sodium myristoyl isethionate Foam height and persistence; long-chain alkenyl can be directional adsorbed to the metal surface to form a dense adsorption layer to protect the metal from corrosion, and can act synergistically with tea saponin in corrosion inhibition; ≡N→O adsorbs H+ in aqueous solution, and partially forms Quaternary ammonium group, which makes it have a certain anti-mold effect, and has a synergistic antibacterial effect with tea saponin, which together guarantees that the product will not deteriorate; in addition, it also has a buffering effect that stabilizes the pH value.

Provided is a composition containing the following components (A), (B) and (C) and suppressing formation of scum during cleansing, wherein a weight ratio of (A) / (B) is 0.2-5 and a weight ratio of ((A)+(B)) / (C) is 0.01-10:(A) N-lauroyl glycine or a salt thereof(B) N-myristoyl glycine or a salt thereof(C) N-acyl acidic amino acid having an acyl group having 8 to 24 carbon atoms, or a salt thereof.
