The location,structure,working principle and the assembling method of a reflex light-tube in a photoelectric pointing system are introduced,meanwhile the effects of installation error and assembling error of the reflex light-tube between two plane mirrors on the accuracy of azimuth transfer are analyzed.Matlab software is used to compute and draw the statistic histograms of the azimuth transfer error and the elevation error,and the results provide a guidance for the assembling reflex light-tube.According to the results from calculation and analysis,the main factor affecting azimuth transfer error of reflex light-tube is the assembling error between the two plane mirrors in the reflex light-tube.As long as the assemble error between the two plane mirrors satisfies the technical requirements of azimuth error≤4″ and elevation error≤0.5′,the azimuth transfer error of the reflex light-tube can be ≤10″ even the installation error extrema in three directions of the reflex light-tube reach 15°.

The design of high speed digital video storage system based on 64-bit operation system is discussed because ultra high frame-rate and high pixel number digital cameras are widely used in the field of optical measurement.This system uses high performance PC as hardware platform and high capacity memory is carried.The software puts image and appendix data into cache in memory during the storage process and after the process the software writes the data into hard disks array.The choke point in unstability of data transfer speed of the increasing number of hard disks is overcomed.According to application the bandwidth can exceed 800 Mbyte/s and the expected result is obtained.

To satisfy rigid performance specifications,this paper provides a design of performance testing system for photoelectricity tracker based on video emulation.It can give a result to evaluate the performance of a photoelectricity tracker by adding emulation video,storing pictures and analyzing images.

A novel silicon-on-insulator thermo-optic variable optical attenuator with isolated grooves based on a multimode interference coupler principle is fabricated by the inductive coupled plasma etching technology. The maximum fibre-to-fibre insertion loss is lower than 2.2 dB, the dynamic attenuation range is from 0 to 30 dB in the wavelength range 1500-1600 nm, and the maximum power consumption is only 140 mW. The response frequency of the fabricated variable optical attenuator is about 30 kHz. Compared to the variable optical attenuator without isolated grooves, the maximum power consumption decreases more than 220 mW, and the response frequency rises are more than 20 kHz.

This study introduces customer value with enterprise performance of structured dynamic game mechanism, the key points and difficulties from three aspects elaborated on customer satisfaction and corporate performance structured dynamic game mechanism of mathematical model, and based on this, puts forward improving enterprise performance strategy.

As the state-owned enterprises are making further reforms and all levels of State-owned Assets Supervision and Administration Commission of the State Council have been established, there is the need to set up a set of state-owned capital management budget, to better reflect the investment and utility of state-owned capital and realize the value preservation and increment. This essay first makes clear the target, main body and composing elements of state-owned capital management budget. The realization of the target of state-owned capital management budget in essence depends on ldquovalue creationrdquo, around which this essay raises the value-based state-owned capital management budget system. Researches discover that economic profit is closely related to ldquovalue creationrdquo, and has great advantage in measuring the value preservation and increment. On this basis, this essay raises the controlling variants and standards of state-owned capital management budget, to form a complete budget control system. Meanwhile, it analyzes the relations between state-owned capital management budget, governmental financial budget and enterprisespsila management budget.
