查询词典 phosphate

And too much nitride and phosphate will cause the water abundant in alimentation.

The profile distributions of silicate, phosphate and nitrate suggest that the organic material decomposition in area is mainly through nitrification during early diagenesis. Based on benthic fluxes of nutrients calculated using Fick's first law, benthic fluxes of silicate, phosphate and nitrate are -886.45~42.62 mol/(m^2d),-3.04~5.83 mol/(m^2d) and -189.43~21.05 mol-(m^2d), respectively, and perhaps silicate and nitrate are one of the major sources of nutrients for bottom water. Our results also reveal temporal and spatial variations of benthic fluxes for silicate, phosphate and nitrate, which may be related to sedimentation environment changes caused by global climatologic change.

The loading process of trehalose has no effect on apoptosis of platelets. The efficacy of trehalose plus phosphate in suppressing apoptosis of platelets during cryopreservation is superior to that of only trehalose. Compared to 6% DMSO and 2% DMSO plus TS, trehalose plus phosphate can retain the same platelet count, superior hypotonic shock response and platelet aggregatory reaction to ADP, and lower apoptosis rate of platelets. Platelets cryopreserved with trehalose plus phosphate can retain intact ultrastructure.
