The energy efficiency of heat pump hosts and systems is calculated based on the test data, as well as the system's energy efficiency, economic and environmental benefits.
Table 4 shows the emission reductions of carbon dioxide, sulfur dioxide and dust of ground source heat pump system compared to conventional electric refrigeration & coal-fired boiler system.

There are mainly three methods to eliminate NOx: (i) the direct catalytic decomposition of NOx; (ii) selective catalytic reduction (SCR) of NOx; and (iii) NOx storage - reduction (NSR) [1].
The texture data of twelve samples prepared by co-precipitation with different calcination temperatures (uncalcined, 600oC, 800oC, 1000oC) are listed in Table 1.

The camera equipment uses ST130C-H Color Digital Video Camera, USB high-speed digital output to receive data directly through the computer, the maximum resolution is 1280 x 960, computer programmable controls the exposure time,brightness,gain and other parameters.
Using the improved dimensionality reduction Hough transform to identify the package position and center coordinates. 100 color images of a resolution of 1000 × 252 are collected to detect in the experiment, detection results are shown in Table 2.
Using a single component method to extract the R component to establish the gray model according to their characteristics, using an iterative method to find the optimal threshold value, using image segmentation to remove complex background, using median filter to smooth the image to eliminate noise area and pore region, using the improved dimensionality reduction Hough transform to identify the package position and center coordinates, sending the center coordinates to the motion control agencies to complete dispensing package in accordance with the specified protocol.

Usage of microfluidic devices allow not only the reduction of the multiple samples used but also a quicker, more efficient and automate detection of different processes, which are optimal characteristics for a portable microfluidic solution, integrated in a microelectromechanical system (MEMS).
Nonetheless, surface modification is needed, with poly(ethylene glycol) (PEG) being an usual surface modifier and allowing a reduction in the contact angle of PMMA from around 70˚ to around 38˚ hence increasing the capillary effect [11].
Further work should focus on the optimization of the occurring filling process and study of new designs, based on the data presented in this work.

However, this method has its own limitations such as high cost, long period, and limited measurement data and so on.
In other words, the noise reduction effect of the ellipsoid nose cone model is better than the hemisphere nose cone model.
Comparison results showed that the noise reduction of the ellipsoid nose cone model was better than that of the hemisphere nose cone model.

The mean particle size reduction in gaseous nitrogen was significantly more than that in liquid hexane.
Despite the fact that majority of the data in the literature indicate that NS materials have higher hardness than corresponding conventional materials, there are several studies pointing out that this hardness increase is not as high as that predicted by the classical Hall-Petch equation [9]. 3.3.3.
A significant reduction in the mean particle and crystallite size with increase in milling time was observed. 2.

Diseases, such as epidemic disease, virus disease, bacterial wilt and damping off, can directly cause the reduction of hot pepper output, and its root cause is not only related to physical and chemical properties of soil[6], but also close with the species and quantity of rhizosphere microorganisms, which is one of the prime reasons for successive cropping obstacle.
After a fixed time of incubation, culture plates were taken out and used to calculate the mean number of bacterial colonies in three plates with the same dilution according to the following formula: CFU/ml=the mean number of bacterial colonies in three plates with the same dilution×dilution ratio×5 Data processing method.The mean square and standard deviation of every measured index were respectively calculated by DPS, and the significance of differences among fluid fertilizer treatments and the comparisons were tested by one-way ANOVA.
As a result, the proper application of fertilizer may perfect the microorganism proportion in the soil and improve the antagonistic effect of useful microorganisms on pathogenic bacteria, which is of significance to the promotion of the greenhouse production, the reduction of cost and the increase of the greenhouse vegetable yield and quality.
