Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

A nanometer anti SARS mask and insulating clothing are made by coverage type nanometer cloth soaked with nanometer particle. The invention adopts macromole polysaccharide, which can combine with virus protein rapidly and effectively as material for preparing nanometer polysaccharide colloid. The average particle parameter is smaller than 100 nanometers in the nanometer polysaccharide colloid. Dips a common non-nanometer cloth in the nanometer polysaccharide colloid and dries it into the coat type nanometer cloth. Four layers coat type nanometer cloth laminate with the two layers common non-nanometer cloth into integrated composite cloth for making mask and insulating clothing. It has a super powerful absorption and insulation function to virus(SARS coronavirus is included) and favorable air permeability function, thus can effectively prevent the virus be passively absorbed into the body.

The invention relates to a combined type respirator, including a first case, at least a first filter medium layer and a second filter medium layer, wherein the first filter medium layer is disposed at the outside of the first case, and the first case is arranged at the outside of the second filter medium layer, while a housing slot is positioned at the outside of the first case to hold the first filter medium layer. The filtration area of the first filter medium layer is smaller than that of the second filter medium layer, and the aperture of the first filter medium layer is larger than that of the second filter medium layer, so the second filter medium layer can filter the air that the first filter medium layer can not filter. Once the first filter medium layer can not be used to filter the air, at least another first filter medium layer is replaced to go on filtering the air. In addition, the first filter medium layer cam change the material based on the using place, for example, the dust free room in the manufacturing process of the semiconductor needs to use the material to filter the sour gas, and the hospital needs the material for bacteriostasis and degerming.
