With the development of space optical technology,space camera is required to be characterized by both high resolution of ground sample distance and ability of multi-spectral imaging.Thus the optical system design must be satisfied with the demand of large field of view and small distortion.Based on the on-axis three-mirror-anastigmat system,a new type of optical system was designed,which is characterized by small central obscuration,low optical distortion and reasonable arrangement of panchromatic and multi-spectral CCD.The results indicate that the field angel reaches 1.6°,the system line central obscure coefficient is lower 1/3,the optical system distortion is less than 0.5%,MTF is superior to 0.47 at 50 lp/mm,the image quality reaches the limit of optical diffraction,when the focal length is 12 000 mm,focal ratio is 12,and the spectrum band is from 450 to 900 nm.So the proposed optical system can meet the demand of high resolution multi-spectral space cameras.

An example of 8× ratio visible zoom system with mechanic compensator was designed.The focal length and angle of vision of the system were 6.5~52 mm and 6.6°~52°,respectively.The modulation transfer function(MTF) is above 0.6 within the whole focal range at spatial frequency of 75 lp/mm,and approaches the diffraction limit.RMS value of spot diameter was investigated.The cam curves after optimization was given.The system has the advantages of simple structure,high image quality,short zoom path and smooth zoom locus etc.

LTE femtocell is very popular in communication fields. The size and the cost of LTE femto BS should be paid more attention. Here, we designed a low cost MIMO RF transceiver for LTE femto base station, which also has small size. After the analyses of the transmitter and receiver requirements, we put forward block level RF parameters. In the paper, the RF transceiver was separated into many sub-modules; each one was separately designed and realized successfully. The final results demonstrate that the fully integrated RF transceiver not only has small size but also met the requirements of LTE femto BS. The approach of design and implementation could be pushed into the commercial use.

To avoid the BP (Back-Propagation) Network's disadvantages of low training speed, prone to trapping in a local optimum and poor capability of global search, this paper establishes the model of manual neural network energy prediction system based on generic algorithm with the research on the Mn-Si alloy smelting of a steel company, by optimizing the initialized weights and threshold of neural network with GA. After the test of the program complied by MATLAB language and the comparison with pure BP algorithm, the results show that the methods suggested by this paper improve both the accuracy of predicting and the rate of convergence.

It is reported that only 3% of total web users via B2B in China have bought online in 2005, most transactions via B2B were in the pattern that can be described as "online transaction, offline payment". Most researchers have focused primarily on infrastructural issues to solve this problem, but we find that Chinese "Guan Xi" culture is tightly linked to "offline payment" E-business, which is both helpful to lessen asymmetric information and results into rent seeking as a cost. Because of the anonymous characteristic of market in B2B, sellers and buyers can make their behavior optimality continuously by dynamic learning process, which can be realized by interplay between individuals in the market. In an unhorizontal game with "Guan Xi", players make their best response strategy even though they are bounded rationality, so they tend to choose the risk dominant strategy stochastically. If a steady equilibrium comes into being in the long run, it is stable stochastically. As for B2B in China, "Guan Xi" is helpful to promote the second best optimality to turn to the best one under some conditions. That is, if the severe supervision is imposed on B2B so as to decrease the benefit form deceit of sellers, or the third part can play its function in supply chains efficiently instead of providing a transaction platform for enterprises, the problem of "offline payment" will be able to be solved before long.

The Chinese information manipulation system is the base of the navigating system. Distinguishing the noise words from the significant words, and picking up the semantics from the text are unsolved difficult problems. We bring forward the information manipulation method combining the key indexing method with the whole-length indexing method, by comparing main indexing methods in common use in the information indexing system and taking the Chinese features of the internal information navigating system. Its implementation is also provided. This new method preferably provides the full and nicety retrieval and solutes the increasing problems of the indexing space. In the end, the indexing method to the data which is manipulated by the Chinese information manipulation system is also provided.
