查询词典 closed-circuit cell

In reaction-injection moldinga mixture of two or more reactive fluids is forced under high pressure into the mold cavity.Chemical reactions take place in the mold rapidly and the polymer solidifies.Various fibers such as glass,graphite,or boron may also be used to reinforce the materials.Structural foams are also produced by a similar methodusing an inert gasand resin mixture.The product consists of a rigid cellular(closed-cell)structure with a continuous solid skin as muchas 0.080 in.(2mm)in thickness.There are several methods for forming structural foams with density reductions as much as 40% from the solid structure.Because stiffness is proportional to the third power of the thickness of a part,for the same weight of material used,cellular structures are stiffer than solid plastics or metals.

Results: The renal perfusion was increased in diabetes group after the injection of alloxan. The PSI, AUC and ascending slope rate of the curve of the time-intensity curve were increased in 1w and 2w with decreased of HPT; the pathological examination exhibited glomeruli hypertrophy and no thickening of basal lamina. The PSI and AUC in 4w and 6w were more than that of control group; the PIT and ascending slope rate of the curve got closed to normal in 4w and 6w; the intercapillary cells increased. The speed of ascending slope rate of the curve in 8w, 10w and 12w was slower, shown as PIT and HPT delayed; the pathological examination showned increasing of mesangial cell, hyperplasia of mesangial matrix and thickening of basal lamina, followed with obliteration of partial micrangium, glomerular sclerosis and reduce of PSI in 12w.
