By analyzing characteristics of the manual flexibility assembly and precise positionsetting assembly in long and narrow space, the paper introduces a integration assembly equipment.

This paper introduces the writer's experience in the manufacture of cylindrical high pressure scrubber with narrow and long channel.

Numerical simulation and experimental study of influence of ventilation on temperature distribution in long and narrow space;

For the long and narrow space at non-normal temperature,it is difficult to lower the temperature to a satisfied degree only by ventilation,but as an assistant method,the fine mist would be effective.

In the case of long and narrow space where a great deal of heat producing, it is feasible to use fine mist as an assistant means to lower the temperature.

The spatial distribution of toxicant species in fires in a long corridor;

A set of reduced-scale fire tests were conducted in a long corridor structure apparatus to study the characteristic of the toxicant species in the transport of fires smoke.

The paper proposes a pattern recognition method for describing the morphological features of plasma jets in terms of aspect ratio by collecting the images of argon and nitrogen plasma jets,extracting their shapes using the digital image processing method.
