Improved mobility will not only expand the applications and efficiency of small satellites, but also potentially increase the task data return, enhance the scientific and commercial value, such as Fig.1 represents PLEIADES which use multi-photo mode to get the image information of a continuous wide area and use multi-zone target imaging to get the discrete distribution of the point target image information[2].
At the same time, there is a gear which drives the frame controlled by stepper motor with speed reduction ratio 20:1, this gear can reduce the influence generated by SGCMG torque output which impacted on the stepper motor.

ZnO nanocrystals of less than 5 nm are fabricated through physical size reduction method and the mediation of defects offer interesting photonic behavior.
Data were recorded using a Theta/Theta Bruker Diffractometer with a Cu Kα radiation, with a divergence slit of 2 o and a 0.2mm width receiving slit.

The open and closed isomers of diarylethenes differ from each other not only in their absorption spectra but also in various physical and chemical properties, such as refractive index [6], oxidation/reduction potentials [7], and chiral properties [8], among others.
As shown in Fig. 3, the quality of images recorded in 1c/PMMA film showed a clear contrast and without cross talk, which are important in rewritable data storage.

In both purification systems, the data are taken until an hour with interval of 15 minutes.
The reduction of CO2 on biogas after zeolite purification process is not influence on the phase changed of zeolite (solid to gas) but influenced on the physical color of zeolite after adsorb CO2 (fig. 4).

SEM images of microstructure for (a) as-received and thermal exposed specimens at (b) 871 oC for 1,000hrs, (c) 871 oC for 5,000hrs, (d) 982 oC for 1,000hrs and (e) 982 oC for 5,000hrs Whenever some equipments and components operated at high temperature and stress are designed, high temperature strength data are needed for conditions for which there is no experimental information.

To tackle this problem, much effort has been devoted to the collection of data on the effects of machining parameters on the process outputs [5].
The results of simulation strongly suggested that the application of this internal lubrication structure cutting tool technology will lead to substantial cutting temperature reduction.

Charge reduction C or metallic films were not deposited on samples studied.
The analysis of literature data and experimental results obtained showed that further researches should be devoted to the surface preparation method and characterization of the substrate obtained to check the dependency of morphological features whether they are characteristics of sol or substrates.

Requirements concerning the reduction of setting-up time and the optimisation of maintenance should be defined as well.
With this data, quantitative dependencies through characteristic numbers will be developed.

Optimal bending force calculation The bending force preset model is to calculate loaded roll gap crown on the basis of the initial data on given strip (steel, width, thickness entrance, finished thickness).
The calculation procedure is as follows: (1) The initial point, unit orthogonal directions, steps, amplification factor, reduction factorand allowable errorare given.

Wastewater from urban areas causes aquatic environment deterioration and freshwater resource reduction, but if it is managed properly for reuse, it can contribute to the conservation of the aquatic environment, to the securing of water resources, and to the enhancement of the urban environment (Fig. 1).
(4) Long-term operation data are needed.
