Considering to establish a national ammunition warehouse data processing of a large number of real-time monitoring information and real-time transmission to the requirement of server hardware resources, it was proposed to build a national ammunition warehouse distributed test system based on grid technology. Experiments show that the system has a scalable computing capacity, high computational efficiency, low cost, and good application prospect.

The solubility of TNT and RDX was measured in supercritical carbon dioxide fluid at 303.0, 308.0, 323.0, 338.0 K, and over the pressure range from 10.0 MPa to 50.0 MPa. This study examined the influences of extraction temperature, extraction pressure and support effect (SE) between molecules of TNT and RDX on their solubility in the TNT/RDX/SC-CO2 system. The results show that solubility of TNT and RDX in TNT/RDX/SC-CO2 ternary system is much higher than that in binary system. The values of SE of RDX and TNT increase first and decrease then with the pressure changing. The pressure turning point occurred over the pressure range from 25 MPa to 28 MPa for TNT and from 13 MPa to 20 MPa for RDX.

The Social Security earnings test reform in 2000 eliminated the earnings test for all individuals between the normal retirement age (NRA) and age sixty-nine. The earnings test has long been accused of imposing a disincentive on the labor supply among older workers. In this article, we argue that the policy change may also have affected the labor supply among people who were just below the NRA around 2000. We utilize approaches embedded with a difference-in-differences design to estimate the anticipation effect on the labor supply of the slightly younger group (aged sixty-two to sixty-four) using an even younger cohort as the control group. Our preferred estimates indicate that the cohort aged sixty-two to sixty-four had worked 5.4 percent more weeks per year and 5.1 percent more hours per week after the earnings test reform in 2000.
