cincture
1.Using carbon isotopes and organism sign compound and character of maturity to compare, we think that asphaltum show in south cincture is from three set source rock of different carbon isotopes-lower Silurian to middle and upper Ordovician, middle and upper Cambrian lower Cambrian & Sinian;
2.Aiming at different requirements for inexplicit transmission positions in V-cincture design described by some teaching materials and manuals, the paper pointed out that the design should be finished according to different mechanical transmission positions.
3.HYL series cincture type presses filter machine has the heavy treatment ability.With such remarkable characteristic as high efficiency and having long performance life etc,it apply to the environmental improvement of every profession and trade extensively.
