Copper is a very important structure material in nuclear fusion engineering. The neutron activation cross section are very useful in fusion research and other applications such as radiation safety, environmental, material damage and neutron dosimetry. More efforts are required to identify and resolve the differences and discrepancies in the existing activation cross sections from different laboratories. The natural copper consists of two stable isotopes, i.e.63Cu,65Cu. The reaction Q-Values and abundances are listed in Table 1.

The phase-locking process is studied for high-power gyrotron oscillator driven by an external signal. The phase-locking nonlinear differential equations are derived, and the condition of phase-locking is shown and analyzed. The phase-locking signal can be introduced after gyrotron oscillates into saturation or before it. Two different ways of inputting signal make markable influence on the phase-locking process, this phenomenon is discussed. In this paper, the numerical calculations and analysis are given for gyrotron TE13 mode.

Bath smelting reduction for recovering zinc from EAF (Electric Arc Furnace) dust has been investigated in the laboratory. A degree of zinc volatilization of more than 99% was obtained from the process. Temperature has a clear influence on the reduction rate of ZnO in slag. The reduction rate of (ZnO) by [C] is the first order with respect to the content of ZnO in the slag. The apparent activation energy of the (ZnO) reduction reaction is 312 kJ/mol at 1300-1500℃.

＜正＞Explosion containment vessel（chamber） is used to protect personnel and experimental equipment in the destruction of explosion *** important issue is how to enhance explosion containment vessel’s performance of withstanding internal intense blast *** work about using concrete or composite material to reinforce explosion containment vessel is being developed in recent years. This paper is devoted to study the dynamic deformation law of steel-concrete structure under internal intense blast loading produced by different charges mass through small-scale model ***-datas of concrete and steel cylinder’ deformation are *** experimental results show that steel cylinders’ axial deformation is not remarkable,circumferential deformation grow with mass of charges *** steel cylinders are damaged,the form of penetrability crack shows that steel cylinders have a shearing fracture form;It indicates that dimensionless displacement parameter of concrete under intense blast loading is a decaying exponential function with scaled-distance *** response of steel-concrete structure under internal intense blast loading was simulated by using LS-DYNA soft.A good agreement between numerical simulation predictions and experimental results of steel-concrete structure deformation was obtained.

Direct current metal filtered cathodic vacuum arc （FCVA） and acetylene gas （C2H2） were wielded to synthesize Ti-containing amorphous carbon films on Si （100）. The influence of substrate bias voltage and acetylene gas on the microstructure and mechanical properties of the films were investigated. The results show that the phase of TiC in the （111） preferential crystallographic orientation exists in the film,and the main existing pattern of carbon is sp2. With increasing the acetylene flow rate,the contents of Ti and TiC phase of the film gradually reduce; however,the thickness of the film increases. When the substrate bias voltage reaches -600 V,the internal stress of the film reaches 1.6 GPa. The micro-hardness and elastic modulus of the film can reach 33.9 and 237.6 GPa,respectively,and the friction coefficient of the film is 0.25.
