Materials and Methods:236 pathology-confirmed breast lesions(155 malignanty,81 benignancy) and 221 disease-free contralateral breast tissues were examined using EPI-DWIb values=0,1000 s/mm~2TR/TE=8400ms/93.8ms; FOV=30×30cm;matrix=128×128;ASSET=2,slice thickness=4mm.DCE-MR imaging was also performed for accurate location of the lesion using VIBRANT sequence.The mean ADC values of malignant and benign lesions and the disease-flee contralateral breast tissues were calculated from the ADC map for each patient.One-way analysis of variance was applied to compare the mean ADCs of malignant lesions with benign lesions and disease-flee contralateral breast tissues.The threshold ADC value for malignant lesion was determined using a receiver operating characteristic(ROC curve analysis.Each lesion was classified into two major types:mass and non-mass lesion.The diagnostic performance of DWI was compared in breast mass and non-mass lesions.Results:155 malignant and 81 benign lesions were confirmed in 236 lesions.

When the amount of SO(superscript 2- subscript 4)/ZrO2 catalyst was 7% of the mass of β-pinene, the yield of product was 62.0%, and the mass ratio of borneol to isoborneol in the product was 13.6:48.7. When the amount of S2O(superscript 2- subscript 8)/ZrO2 catalyst was 7% of the mass of β-pinene, the yield of product was 66.7%, the mass ratio of borneol to isoborneol in the product was 11.5:49.5. Both two catalysts were poor for borneol selectivity.

By non-enhancement scan, 12 cases showed low density mass, 4 cases equal density mass, 1 case slightly high density mass, and 2 cases stippled calcification mass. By enhancement scan, 13 cases showed inhomogenous enhancement in cortical phase, 2 cases showed slight to moderate enhancement. Another 2 cases of small cystic RCC presented enhancement of wall with nodules and the partition.

The efficiency of mass transfer in 60% fraction of hole is higher than in 40% fraction of hole. When gas/liquid ratio is lower 10, the efficiency of mass transfer in new sieve baffle tray is higher than in traditional tray.A three-dimensional quasi-single phase computational fluid dynamics program with the RNG- turbulence model is presented for evaluating the performance of the new sieve baffle tray. The special feature of this model is taking into account the influence of heat transfer during the mass transfer and the influence of mass transfer in computing the flow field.
