Blomidon trees are proposed as object of study, of which measurement data is obtained, referring to the data measured by the research group.
Belt driving 3.Clutch 4.Reduction gears 5.Guard board 6.Picking head 7.Device of collection boards 8.Collection groove Body of the picking machine is designed into the shape of door, which "ride" fruit trees and of which wheels in the ditches on both sides when it is walking vertically.
As the gasoline engine is started, the clutch is closed and at the same time the reduction gears are driven through belt driving.
Piching head is driven by the reduction gears through belt driving.
As the research of blueberry picking machine is limited, there is a lot of research work, such as the experiment of different varieties, the experiment in different gardens, the improvement of structure, time of field trials and the effects of the test environment and mechanical flexibility and operation technology on experiment data. 1 Foundation Project: supported by “the Fundamental Research Funds for the Central Universities”(2572014AB04) and Project 948 of State Forestry Bureau (2011-4-21) Author: Bao Yudong (1986-), male, Fushun, Liaoning Province, PhD graduate, majoring in research of picking machine and robot of agriculture and forestry, and mechatronics technology.

(2) Project example of energy-saving residential quarter Initial data of energy-saving residential quarter.
According to specific measuring and analyzing of the owner in energy saving 65% project .we get its use cost data as follows.
Still selects A-8 in the residential quarter as the research object, we suppose it is designed and constructed with no energy saving measure, preparation cost and construction cost is 2320 yuan/m2,heating cost is 3.3 yuan/m2,other data are the same, then the life cycle cost analysis of no energy saving project is shown as follows[5]: construction cost :12056×2320=27970000yuan special maintenance cost: 12056×60 =720000yuan annual property management fee: 12056×1.2×12=170000yuan annual use cost:12056×3.3×5+(880+200+600) ×82+12056×1=35330000yuan disposal expenses: 12056×20 =240000yuan salvage value: 2797×3%=840000yuan Assumptions for 6% discount rate, life period for 30 years, the calculation process of dynamic life cycle cost is:

Each of the three cells was instrumented with thermo-hygrometer (Pt100 and capacitive sensor) with automatic data registration, twelve type T (copper-constantan) thermocouples and two heat flux meters.
Data readings were made every minute by an acquisition and automatic registration system (data loggers); average values were recorded every 10 minutes (average of 10 readings).
a) b) Fig. 3 - a) Schematic representation of the instrumentation plan in the roof slab surface; b) Interior cell general aspect - thermal-hygrometer position and data acquisition system Constant indoor temperature in the conditioned regime was achieved by mechanical systems.
The recorded data is currently being analyzed in order to assess the influence of the building envelope in heat pumps performance in real operating conditions.
However, during winter, they lead to an increase in energy requirements to obtain adequate thermal comfort since there is a reduction in roof solar gains.

Its original data were 40 μm in particle size.
The reduction rates of friction coefficient and wear rate of PP/OMMT nanocomposites compared with bare PP at different load are shown in Tab. 1.
With the increase of load, the reduction rate of wear rate of nanocomposites, compared with pure PP at the same load becomes worse, from 60 % to 35 %, while that of the friction coefficient becomes better, from 4 % to 10 %.

Moreover, in the stage of self-organizing, OMMT galleries have a tendency of paralleling to worn surface under the work of heat produced from friction, which contributes to the reduction of friction coefficient in the course of friction.

Optimal build direction   and slicing strategy address the reduction of roughness due to the staircase effect.
About the same level of Rz reduction is achieved with four GB passes.
Most significant Ra and Rz is observed when spraying putty was applied (61.26% Ra reduction and 67.41% Rz reduction for samples with 0.254 mm layer thickness).
Presented results also shows that surface pre-treatment with MEK before blasting can lead to roughness reduction and surface quality improvement.

The product and reactant were analyzed by an on-line gas chromatograph equipped with a TCD and a data integration system.
H2-TPR profiles of catalysts are shown in Fig. 2 The bulk NiO sample obtained by calcination of Ni(NO3)2 displayed a reduction peak around 350℃.
A low reduction peak below 350℃ was observed on the TPR profiles of Ni/Al2O3 and Ni/Ben, which might be associated with the presence of Ni3+[4].
Besides the low reduction peak at 300℃, two separate peaks at 488℃ and 657℃ were present on the TPR curve of Ni/Ben, respectively.
The Ni/Al2O3 TPR profile showed a broad peak, either due to the reduction of various Ni species or to the reduction of one nickel oxide species by steps.

On the other hand, Ni/4H-SiC Schottky contacts fabricated on the sulfurized 4H-SiC surface showed a 0.3 eV reduction of the average barrier height with a narrower distribution, with respect to the untreated sample.
The Ni/4H-SiC Schottky contacts fabricated on the “sulfurized” 4H-SiC surface exhibited a 0.3 eV reduction of the Schottky barrier with respect to the “untreated” sample (not subjected to sulfurization).
The continuous lines are a linear fit of the experimental data, from which the ideal values of the Schottky barrier height can be extrapolated (at n=1).
Here, a reduction of the surface potential of ~0.3 V is observed on the sulfurized SiC.
As can be seen, a reduction of the 4H-SiC electron affinity and Fermi level pinning at the surface induce a lowering of the Schottky barrier height in the sulfurized sample.
