In this paper, we prove that if any set of ｜E（G）｜- ｜V（G）｜＋ 1 facial cycles of a 3-connected planar graph G embedded in the plane doesn＇t form a minimum cycle base of G, then any minimum cycle base of G contains a separating cycle, and G has a minor isomorphic to T6, where T6 is the graph obtained from the complete graph K6 by deleting a path with four edges.

The relationships among the deformation, texture and properties of TA16 alloy tube were investigated, an optimum processing parameter was obtained. High Q (the ratio of reduction of diameter to reduction of wall thickness) values increase tensile, flaring properties and reduce flattening; high Q values increase tensile strength, flattening, flaring. and decrease tensile elonga. tion. The main circular textures of rolling tubes are basal (0001) and pyramidal {1015}, {1014}, {1013} etc., and the main axial textures are prism {1010} and pyramidal {1120}, {2131}, {2021} etc. under different Q and E values. There are greater changes in the grain size under different E values, compared with that under different Q values.

The corrosion behavior of Ti-2A1-2.5Zr alloy with 5 alloy contents and 5 surface states were studied in water steam at 400℃, 10.3 MPa for 72 h. The weight-increments of all samples are under 4 mg/dm2, better than Zr and Zr-alloy. or-Ti is oxidized into anatase-type TiO2 preferentially. The corrosion resistance is improved by adding Al element or pre-oxidizing treatment, the latter is more effective relatively.

The SEM observation in situ of monotonic and cyclic deformed structure in Ti-ZA1-2.5Zr alloy was performed. The regularity of slippage, crack nucleation, propagation and the typical dislocation configuration were also investigated. The twin and twist play an important role in maintaining homogeneous deformation in the final plastic deformation stage.

Transverse localization of the optical Tamm plasmon （OTP） is studied in a metal-distributed Bragg reflector （DBR） structure with a one-dimensional disordered layer embedded at the interface between the metal and the DBR. The embed- ded disordered layer induces multiple scattering and interference of light, forming the light localization in the transverse direction. This together with the formation of Tamm plasmonic modes at the metal-DBR interface （i.e., the confinement of light in the longitudinal direction）, gives birth to the so called transverse-localized Tamm plasmon. It is shown that for both transverse electric （TE） and transverse magnetic （TM） polarized light injection, the excited transverse-localized Tamm plas- mon broadens and splits the dispersion curve due to spatial incoherence in the transverse direction, thus proving the stronger light confinement especially in the TE polarized injection. By adding the gain medium, specific random lasing modes are observed. The proposed study could be an efficient way of trapping and locally enhancing light on a subwavelength scale, which is useful in applications of random lasers, optical sensing, and imaging.
