Software rating ascertainment is very important in development of space camera software system. It can guide the software measurement and management  and help designer improve system reliability finally. Fault Tree Analysis is a common method to analyze the danger reason and fix on bottom events. The most significant step is calculating the occurrence probabilistic of top event  namely the occurrence probabilistic of dangerous event. Because software failure cause is anfractuous and available data are hard to get  a modeling method for bottom event is proposed based on Vague set to calculate the occurrence probabilistic of top event. Experimental results show that the new approach of Vague set can guide the Software rating ascertainment which is ascertained using qualitative analysis. The results also show that the new method makes software rating ascertainment have the quantificational evidence. 2010 IEEE.

The common bus on bus control is RS232. With the development of field bus technology  field bus technology is widely used in data recorder. How to real time record the data of field bus in the experiment and provide the test data for process reconstruction is a very important problem. This paper introduces a kind of data acquisition and storage based on field bus. Its core design is C8051F040 microprocessor and SJA1000  a widely used field bus controller. This paper presents the basic constitution of this field bus data recorder and set forth its hardware and software. This field bus data recorder field bus real-time gathers the information and storage data on the CF card. The result of the experiment shows the system is highly reliable for data acquisition and storage  which should have abroad application prospect for data record experiment. 2010 IEEE.

The first impression of any building to a person is its exterior and decoration  therefore  at the same time  and therefore the quality of decoration project shows the more important position in building project. A lot of projects produce quality problem because of the material color difference  how to grasp and control the color change of building materials  the color difference problem laying stone materials is also studied in this paper  which exists universally at the common project  and carry out color quantification  and the solution scheme has been given using this system.  and is often found at the high-grade decoration  it has the very important meaning. According to the color theory  a computer vision system used in color quantification measurement is established  the standard illuminant A is selected as the light source. In order to realize the standardization of color evaluation  the mutual conversion between RGB and XYZ color space is studied  which is realized by the BP network. According to the colorimetry theory  the computer program is compiled in order to establish the software system  and realize the color quantitative appraisement in whole color gamut. LCH model is used at quantifying the color of building materials  and L*a*V model is used at comparing the color change. If the wooden floor is selected and laid improperly during family fitment  it is easy to present "flower face". The color also arises greater discrepancy using the laths of same tree. We can give the laying scheme using the color quantification system
