A patient with sore and ulcer on upper lip and facial flush for 4 months was first treated by warming yang and transforming fluid, clearing heat and resolving dampness, but with little effectiveness; he was then treated in vain by clearing heat and relieving toxin and downbearing heat; finally he was cured by enriching yin and suppressing yang and downbearing fire to its origin.

It expounds the availability of moxibustion on chronic pharyngitis and puts forwards the doubt of efficacy of inducing fire to the origin of TDP magic lamp and moxibusiton from aspects of mechanism and present treatments.

Trial use of Potassium Picrate for producing fuse head;

The firing reliability and simultaneity of the industrial electric detonators which are currently widely used were insufficient because KClO_3-C-DDNP was used as kindling to the production of fuse head,it also brought about problems of safety and pollution.

The working principle,features and application of the automatic welding machine for welding resilient ignition element of electric detonator of our country are presented.
