The system works as follows: Ammonia (state 1) of the hot water in the heating generator generated in the solar collectors, the heat generated by the high pressure ammonia vapor (state 2) enters the injector, to form a high speed air flow through the nozzle, the evaporatorof ammonia vapor (state 3) is sucked into the injector, while maintaining the degree of vacuum and low temperature of the evaporator, to produce refrigeration.
To ensure the cooling effect of the air-cooled condenser than large, air-cooled structure eliminating the need for cooling water system, the entire solar jet refrigeration system needed by detailed calculations to determine the air-cooled and water-cooled two ways Which more and materials and land.

With regard to the structure of hardware, [1] presents two techniques that greatly reduce the vulnerability to nuisance tripping: phase detection to eliminate sensitivity to capacitive leakage, and a more elaborate two-stage time delay to reduce vulnerability to transients. [2-5] presents that current transducer were made by different processing and different materials in order to overcomes the problem of the saturation and the low transient accuracy of current transducer.

Because of the distinct difference in the material, structure
form and load condition between the deep-sea submersibles and the submarine, it is necessary to
consider the application bound of these equations or charts in criteria[1].
The material of the shell is Titanium alloy which is used to deep-sea submersible metals for low weight, strength, and highly corrosion-resistant.
Here are the material parameters: the yield stress s is about 840Mpa; the elastic modulus is equal to 115Gpa; the density is 4540.8kg/m3; the major poisson's ratios is 0.35.

Since the analysis was performed in a nitrogen atmosphere, the mass loss is attributed to extensive non-oxidative degradation that is evidently facilitated by the nanofibrous morphology.The thermal characteristics of the PLA source material as, powder, cast film and NF were determined using DSC as shown in Figure 3A.

Abstract.
Introduction Recent advances of the biological sciences and culture methods have allowed us to control cellular defferentiation and growth.
Combining this cultured bone tissue with synthetic bone material has allowed the production of synthetic bone with increased osteogenic potential [4-6].
Materials and Methods Preparation of cryopreserved marrow cells Marrow cells were obtained from the bone shaft of femora of 7-week-old, Fischer 344, male rats and were cultured in standard culture medium (SCM) of MEM containing 15% fetal bovine serum and antibiotics.
