1.An Al-rich phase in rapidly solidified (RS) Al-8Wt%Fe-4Wt%Ce-3Wt% Ti ribbon was studied with convergent beam electron diffraction (CBED), high resolution electron microscopy (HREM) and energy dispersive X-ray spectroscopy (EDS) in an analytical elec- tron microscope.
本文用分析电子显微镜(AEM)对快速凝固Al-8Fe-4Ce-3Ti(重量百分比)条带中—未知相进行了会聚京电子衍射(CBED),X—射线能谱(EDS)及高分辨分析。
2.With additives,the conversion rate of cBN,crystal size as well as the color are improved obviously. When the content of additive is 0 ~ 4 wt %,the conversion rate of cBN rises,the crystal size become larger,and the crystal color goes to amber gradually. When the content of additive is 5 ~ 8 wt %,there are some brown and black crystals in the obtained cBN crystals,the experimental repetition rate is low.
加入添加剂后,随添加剂加入比例的改变,cBN的转化率、粒度和颜色都有很大的变化,添加剂占实验样品重量百分比为0~4%时,cBN晶体转化率逐渐提高,晶体粒度逐渐增大,晶体颜色变深,当添加剂的重量百分比加大至5%~8%时,出现部分深棕色至黑色的cBN晶体,合成实验重复率降低。
3.After 2 hours reperfusion, infarct size and risk region were measured by postmortem dual dyes with triphenyl tetrazolium chloride (TTC) and Evans blue.
家兔处死后以Evans蓝及氯化三苯基四氮唑 (TTC)双重染色确定缺血及梗死心肌范围 ,心肌梗死范围以梗死心肌占危险区心肌重量百分比 (MI/RISK)表示。
4.Water content at field capacity is usually expressed as a percentage of the weight or volume of oven-dry soil.
土壤含水量一般用干土壤的重量或体积百分比来表示,它受土壤质地的影响。
5.Results: Blood MDA level,protein concentrations,WBC count and PMN percentage in broncho-alveolar lavage fluid of group I/R were significantly higher than those of group C and group E(P<0.01),and there was not significant difference between group C and group E(P>0.05);
留取肺组织标本,测定肺组织湿、干重量,计算干/湿重比(D/W)及行肺组织病理检查。 结果:I/R组血浆丙二醛含量、支气管肺泡灌洗液中蛋白含量、支气管肺泡灌洗液中WBC总数及中性粒细胞百分比明显高于C组及E组(P<0.01),E组与C组比较,无统计学意义(P>0.05);
6.Total body fat depots[BMI, percentage of body fat (FAT%), and body fat mass (FM)], regional body fat depots[waist circumference (W), hip circumference (H), W and H ratio (WHR), abdominal subcutaneous fat area (SA), intra-abdominal fat area (VA), and femoral subcutaneous fat area (FA)]were measured on all subjects. Fasting serum adiponectin level was determined by radioimmunoassay.
同时测定总体脂[体重指数、体脂百分比(FAT%)、身体脂肪块重量(FM)]、局部体脂[腰围、臀围、腰臀比、腹部皮下脂肪面积(SA)、腹腔内脂肪面积(VA)和股部皮下脂肪面积(FA)],并应用放射免疫法测定空腹血清脂联素浓度。
