Wan et al. [10] reported a reduction in evaporator wall temperature and total thermal resistance of about 12.8% and 21.7% respectively.
It includes the compact loop heat pipe assembly, a dc power source, a data acquisition unit, a watt meter to indicate the load given and computer for recording and monitoring the system parameters.
The temperatures were measured every 3 s.This is set as the time interval in the data logger DARWIN DAQ-100.
The readings are recorded by the data logger and stored in a computer for further data processing.

The energy consumption of China's high level of energy-consuming industries than the energy consumption per tonne of soda ash is about 20%, energy consumption per tonne of caustic soda at about 14.7% higher.Therefore, we assume that: in 2006, respectively caustic soda, soda ash comprehensive energy consumption as the benchmark, caustic soda, comprehensive energy consumption reduction of 1.7% per annum by 2020 standards to the international advanced level 1100kg standard coal / t of caustic soda, reduction of 0.5% every year since then.Soda ash comprehensive energy consumption reduction of 1.3% per annum by 2020, the standard level of 330kg to reach the international advanced standard coal / t soda ash, reduction of 0.5% every year since then.Forecast results in Table 7.
(3)Alkali industry mainly because of CO2 emissions from electricity generated in the process ,we can see from the forecast data since 2010 ,after decreasing in 2020 compared with 2010 to reduce by as much as 50%,mainly because the future generation will be slow.Slow changes in the dominant position of coal, China's energy structure to the direction of cleaner low-carbon development, and greater use of hydropower, nuclear power and bio-energy generation
(4)Alkali production capacity from the forecast, energy demand, CO2 emissions from the whole, the next few years, China will continue to increase the amount of alkali production by 2010 after a gradual reduction in energy demand and CO2 emissions will also be gradually reduced.

A new method is proposed which use optimization modules of finite element established by Ansys Parametric Design Language program to inverse rock mechanics parameters of surrounding rock with the logging data of casing deformation.
The method makes it possible to inverse rock mechanics parameters in the formation where the data of rock mechanics parameters measured are scarce and is more efficient than the traditional method.
The lack of the data of formation where casing deformation exists and the changes of mechanics parameters of rocks which make the casing pipes deformed lead to unreliable workover operations.
There are surely differences between the measured data and simulation results.
The results correspond to the in situ data in zhongyuan oilfield, which prove the feasibility of inversion.

A statistical analysis of St 37-3 steel de-oxidation data was performed with the aim of improving the efficiency of steel de-oxidation technology in a ladle.
The averaged production data for the production of steel St 37-3 are presented in Table 1.
The quantitative effect of metal temperature on the assimilation of deoxidizing agents can be estimated from the data in Fig. 2.
From the data presented in Figure 2, it follows that an increase in metal overheating impairs the assimilation of silicon and manganese at any level of metal oxidation.
The data in Figure 2 confirm the earlier conclusions about the adverse effect of metal oxidation on the efficiency of deoxidation.

Description of Tests and Data Processing
After 28 days of curing, the three cast slabs were tested for static load.
Each excitation and response signals lasted 4.0 secs and had a total of 4,096 data points.
The data was acquired and processed by the spectrum analyzer Dataphysics model Quattro, so as to obtain the frequency response functions (FRFs).
The aim of these tests was to provide additional data to investigate the pattern of changes induced by cracking.
This data provides a strong indication that the changes on modal properties were controlled by the ribs only and the concrete topping had little effect on them.

Mining partial orders from sequence data is an important data mining task with broad applications.
Particularly, [7] worked on sequence data and investigated the problem of mining a small set of partial orders globally fitting data best.
Different from our work, they tried to find some partial order that fit the whole data set, assuming that the whole data set somehow follows a global order.
