A large scale manually annotated Chinese corpus and a number of well-conducted experiments were used to identify the following points of the hidden Markov model based part-of-speech tagging scheme for Chinese texts. The results are:① The Bigram model is better than the Trigram model in terms of the performance-cost ratio.② An annotated corpus of about 70000 words tokens would be sufficient for training the Bigram model, to produce system performance of about 93% tagging accuracy for ambiguous word tokens and 97% tagging accuracy for all word tokens in the texts.③ The Bigram model can be suited to different application domains quite well.

Arbitrary waveform generator is widely used in experiment and practical work as signal sourer. Apply the HSO function of 8OC198KC MCU to generate PWM waveform, then use the PWM to compose arbitrary waveform. The concrete hardware control circuit and the software realization method are presented. Then take the three-phase SPWM waveform generator for example, pot forward the application circuit and show the result of test. Experiment shows that the waveform distortion of sine, triangle and sawtooth is small and the operation is simple. The performance is high.
