2.We allow you half of the invoiced amount for packing if you return the empty crates.
4.Abstract: The distribution of cooling air which is in the grille-brick of the inner combustion hot air stove has been simulated with three dimension turbulent mathematical model so as to find a method which is used to improve the distribution of cooling air in hot air stove.The influence of differential horizontal plates on the distribution of cooling air is discussed.The results show that original big circle round field of flow in the pillar-cavity is changed into full one-way field of flow and edges gas flow,at the same time, is increased by horizontal plates.There is a different function with horizontal plates and vertical plates.To make the uniform distribution of cooling air in the hot air stove, it is necessary that horizontal plates and vertical plates are used in a combined way.
5.Platen backhaul height can be set in a random manner, therefore reducing the spare travel.
6.The results show that the latter welding method delivers higher load capacity and slightly lower stiffness of main girder, and simpler welded structure and technology.
7.The system makes use of the connecton of gypsum board and ceiling suspension,and forms cavity (or fills with sound-absorbing material).That can well solve the promble about insulation of heat and sound,etc.
8.Results: Cartilage endplate in normal control group show lots of oval cartilage cells of normal structure, little cartilage cells of denaturation and compactness and regularity of collagen arrangement, and in the model group show lots of cartilage cells of denaturation and contraction, little cartilage cells of solution, loosing and irregularity of collagens arrangement and solution of lots of collagens.
9.There are two methods for welding radial stiffeners to bias-rail box girder: welded all around and open at tensile flange.
10.And he put the staves into the rings on the sides of the altar, to bear it withal; he made the altar hollow with boards.
