Refer to results achieved by study of effect of TiO_2 on mullite synthesized from analytical grade raw materials,effect of TiO_2 on mullite synthesized by reaction sintering method was studied using different grade bauxite、SiO_2 and TiO_2 as raw materials.
in different stage blastocysts recovered at D7 after insemination was similar to that in the corresponding stage blastocysts recovered at D8 or D9. However,a larger variation in cell numbers was evident among different grade D9 blastocysts than in D7 or D8 blastocysts (P<0. 05).
results A meta-analysis of clinical data according to 25 articles(5～29)of 1633 cases with MOFE during the past five years from 14 provinces,municiplities directly under the central government,different grade hospitals,10 different subjects.
Results:89 cases(88.1%) outs of 101 cases were totally removed under microscope the symptoms of the 92(90.1%)cases were improved or no changed 9 cases (8.9%) were appearing different grade function obstacle. No death cases among operating or after operating.
Patches can cause a different grade of skin occlusion, depending on matrix composition and thickness, backing layer material.
Synthesis of fullerenes from graphite powders of different grade was studied in a radiofrequency (RF) plasma reactor.
Findings were analyzed with statistical methods; distribution of survivin expression and Ki-67 LI values were determined for different grade meningiomas.
The measurements show that the different behavior of phase-slip centers in Sn microbridges and Sn whiskers observed in former experiments may be a consequence of the different grade of homogeneity of these specimens.
It predicted academic performance at six different grade levels, even beyond Big Five traits.
