Introduction Since advantages of economic benefits, and energy saving and emission reduction, the solar hot water system is preferred in a variety of schools, resident cells, hotels, restaurants, hospitals, and bath centers [1,2]. <0}{0><}.In recent years, the medium and high temperature solar heating technology is being widely used in governmental agencies, schools and factories for living hot water supply and industrial energy saving, enabling solar hot water applications to have entered a new age with technical, large-scale, high-quality and high-performance development [3,4]. <0}{0><}0{>From analysis of hot and boiling water consumption in public service units, in summer, a large amount of boiling water for drinking and a small amount of heat water for bathing are required. heat water for bathing its temperature is low, with less calories, and boiling water for drinking its temperature is high,with very more calories; in winter, relatively a small amount of boiling water for drinking
The heat storage tank, circulating line, water supply and return line were respectively installed with various types of signal sensors monitoring of water level, pressure, and flow data.
With respect to environmental temperature, solar radiation intensity and accumulated radiation quantity, the TRM123 temperature radiometer was used to automatically record and store relevant data. <0}{0><}0{>All wind speed values came from records manually read out from the QDF thermal-ball micro wind-gauge
The test data, selecting the daily solar radiation (about 12.5 ~ 13MJ) under essentially the same conditions were analyzed in Figure 5.

The effects of these measures were analyzed through spatial simulation so that the design of preventive engineering measures can be designed reasonably, and prevented effectively from the impact of dam hazard, and the purpose of hazard prevention and reduction is achieved.
The geographical features of the Enna region in southern Italy were analyzed by Francesco Castelli, and the spatial movement and evolution of the soil and rock flow were deduced by combining with historical data [8].
Joseph Mtamba used radarsat-2 and Landsat TM data analysis to discuss the Manning factor characteristics of the valley terrain, and provided new research methods for the evolution of the flood [9].
In order to compare the schemes further, four meshes on the edge of the village were selected to carry out the detailed simulation data analysis.

Undeniable that the STS injection had solved the problem for water-solubility of Tan-IIA and had made a great contribution to the development of intravenous administration of Tan-IIA, but because of the structure of Tan-IIA was changed, resulting in its pharmacological effects in clinical practice having a certain degree of reduction [1, 9].
The data of stability constants, entrapment efficiency of Tan-IIA -LM were displayed in table 3.
Using DAS2.0 pharmacokinetic software, plasma concentration-time data were processed and the pharmacokinetic parameters were calculated by the statistical moment method.
The data were analyzed by SPSS11.5 statistical software .The results in table 4 show that Tan-IIA lipid microspheres in rats in vivo bioavailability degree (AUC), peak concentration (Cmax) were 2.14, 2.22 times than the STS, respectively.

These defect properties of solids include the electronic structure reflected in optical and spin resonance data, formation energies, and diffusion parameters.
The reduction in surface energy due to inward relaxation will be partly balanced by the increase in elastic energy.
Their disadvantages include truncation problems and their inability to reproduce the harmonic data of the crystal.
From the trapping model analysis of positron annihilation data Kim [85] has found out the vacancy formation energy as 1.28±0.23 eV.
However, the analysis of self diffusion data in FCC metals [120-122] reveals that with rising temperature the contribution of divacancies may also become prominent.

Figure 2 analyses the trends of data.
It is obvious from the above data that China's industrial solid waste treatment capacity has obvious difference from production capacity, the produced industrial solid waste every year has the utilization of only 50%, with about half of the solid waste we cannot use.
From a global perspective, different countries have different methods for the disposal of industrial solid waste, which base on the characteristics of each country and focus on harmlessness, reclamation and reduction.
Another advantage is that, because the specific department and staff in the unified management responsible for the overall monitoring phase and the disposal phase, this method enable researchers to collect and analyze more comprehensive scientific data and then support the scientific research of harmless disposal of solid waste.

The cutting forces were measured with a piezoelectric force sensor and recorded into data files from which the force components and the resultant cutting forces were extracted.
The data was analyzed and plotted using numerical software.
All data were collected for a workpiece overhang of 40mm.
Even small changes in the processing conditions can result in quite substantial reduction in vibrations.

The data related to melting endotherms are given in Table 4.
These data show distinctly different mechanism for thermal and thermo-oxidative degradation behaviour of nanocomposite.
At 10% loading, there was further enhancement of induction time to about 115 min. and a reduction in total weight loss to about 4% after 180min.
