The paper introduces usage of the system of PC2 in the contest: Installation and configuration of server and client, usage of the administration and judgment, management of the questions and answers, analysis application question in the PC2 system, management of the contestant data.
In the process of instructing the 2005 National Undergraduate Electronic Design Contest to complete the F topic "The Digital Controlled DC Current Source". After a careful study of the design topic,a scheme of indirect control current using DAC1201KP-V 12bit D/A converter as its control core,combining the common operational amplifier and the Darlington transistor was proposed.

79 competitive online algorithm for two processor real-time systems with uniform value density
We consider the problem of competitive on-line scheduling in two processor real-time systems.
In this paper we show that the competitive multiplier of Safe-Risky-fixed Algorithm in  is really 3 and presents a modified algorithm (Safe-Risky-unfixed Algorithm) that achieves a competitive multiplier of 2.
For the first case, an on-line algorithm with competitive ratio 119/44 is given.
Two DREB-like genes from Bermuda grass that are induced by low-temperature or high-salt stresses were cloned using RT-PCR and RACE methods, and were named BeDREB1 and BeDREB2, respectively (GenBank accession No: AY462117 and AY462118).
In the pathosystem of potato and the causal agent of late blight, the β-glucan caused a local and race-specific suppressor effect on the plant host defense response.
Resistance of transgenic cultivars based on the expression of one or more resistance genes is sooner or later broken by pathogens whose race-producing rates are high.
Hydrolysis of conjugated forms of salicylic acid and accumulation of its free form was observed after infection of potato tubers (Solanum tuberosum L.) with an incompatible race of phytophthora or treatment with an elicitor (chitosan).
Infection of tubers with a compatible race of the pathogen or treatment with a suppressor (laminarin) decreased both the degree of hydrolysis of conjugated forms of salicylic acid and the accumulation of its free form.
