The comparison and analysis of short-time heart rate variability in different diseases;

Objective To observe the influence of gender and age on the short-time Heart Rate Variability(HRV).

Methods Short-time HRV from 66 normal children and 29 adults were examined.

Practice of short process of cleaning and carding;

The management process r estructuring can overcome some disadvantages of traditional structure, such as unsmooth information transportation, high management cost, lower efficiency and information transpor tation distortion etc, to seek for the aims of short process and high efficienc y, and quickly control management function, so that competitive ability of ente.

The equipment arrangement at hot charge area and furnace area effectively matches the short process continuous rolling production.

Simultaneous short-cut nitrification and denitrification;

Characterization of short-cut nitrification using immobilized ammonia-oxidizing bacteria;

Short-cut nitrification characteristic of aerobic short-cut nitrification granular sludge under high dissolved oxygen condition

Traditional differential optical absorption spectroscopy(DOAS) can be applied to realize accurate, rapid and in-situ concentration measurement of atmospheric trace gas while large error will occur when applied to the measurement of low concentration gas at short light path length.

Preparation of Tin Prill by Short Flow Casting;

This paper describes the typical long flow technique and short flow technique in iron and steel metallurgy,explains the necessity of reconstructing Chinese short flow for domestic iron and steel industry according to the practical condition of lack of natural gas at home,presents several new short flow modes suitable for China.
