The physical and chemical properties of the sorbents were characterized by scanning electron microscope and mercury porosimeter. Their sulfation characteristics were tested on a bench-scale fluidized bed reactor.

在小型流化床反应器中对5种钙基吸收剂的脱硫反应性能进行了实验研究，并利用扫描电镜和压汞分析等方法对吸收剂反应前后的微观结构进行了分析。

In order to compare with normal wet spinning PAC fibre, the morphological characteristics, including void siz, distribution, volume, shape, location, surface crevices etc. of the polyblend fibre and their change during stretching, was studied by SEM, SAXS, porosimeter and water retention methods.

用SEM、SAXS和保水率测定等方法，在与普通湿纺法聚丙烯腈纤维对比的基础上，对丙烯腈共混纤维在拉伸前后的形态特性，包括孔穴大小、体积、形状、位置和表面裂缝等进行了研究。

Comparing granular NiP/Al_2O_3 catalyst with pellet NiP/Al_2O_3 catalyst, SEM , XPS and the catalytic activity gave the evidences that the NiP alloy broke off from the support which mainly leads to the deactivation of the pulverous catalyst.

通过对粉末和球形颗粒催化剂反应前后的SEM 和XPS 及催化剂活性对比分析，证明了粉末状非晶态NiP/Al_2O_3 催化剂失活原因主要是活性组分集团NiP的脱落。

In part three, aiming at CFS using Chinese herb to cure, investigate on fatigue symptom score's difference and efficient quotiety in treatment group and control group before and after treatment.

ResultsAfter therapy 13 cases (59%) were detected remanent carcinoma, in which 5 cases were high degree of therapy effect, 5 cases were medium and 2 cases were mild.

笔者对 2 2例前列腺癌治疗前后的形态学及免疫组化改变进行对比分析，并探讨这一系列改变的临床意义。1 材料与方法2 2例前列腺癌均为 1996～ 2 0 0 1年间上海市第六人民医院病例，治疗前 2 0例经前列腺穿刺活检证实为原发性前列腺癌，2例术前诊断为良性前列腺增生，在经尿道或耻

For the perovskite LaCoO 3 samples before and after activation sulfurization, the experiments of SO 2 TPD, O 2 TPD, and CO combust ion in the presence of SO 2 showed that the activation sulfurization of LaCoO 3 can inhibit the formation of sulfate.

通过对硫化前后的催化剂进行O2 TPD和SO2 TPD分析，认为CO还原SO2反应机理可能是在一定的温度下，在钙钛矿LaCoO3 上发生CO氧化燃烧反应，在硫化物La2 O2 S上发生CO还原SO2 反应，两者相互促进

Fig. 7 shows 3D images and surface roughness of the Siwafer by AFM to compare the unimplanted with implanted surface.

图7显示的是原子力显微镜下硅片在注入氮离子前后的三维立体和表面粗糙维度对比。

Methods: 101 patients who were diagnosed CIN with pathologic histology with vaginoscope were operated on conization of cervix, and compared the pathologic results before and after the operation.

对101例阴道镜活检诊断为CIN的患者行宫颈锥切术，对比手术前后的病理结果。

In addition, it is well known that axial force coefficient denotes the pressure drop across the turbine to a great extent.

因此，如果知道了轴向力系数，就可由透平的运动状态获得透平前后的压降。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
