Methods Porcine bile duct and ureter were treated using detergent sodium dodecylsulphate and 1% Triton X-100 to prepare the acellular lumens matrix. The toxic effects of different concentrations of acellular lumens matrix extract were tested by MTT to assess the proliferation of human scarfskin fibroblasts. The cytotoxicity of the target biomaterial was graded according to the national standards. The growth manner of the human intrahepatic bile duct endothelial cells seeded on the acellular lumens matrix was studied after 20 d under scanning electron microscopy.

Actual X-ray studies of speech illustrate the importance of the articulatory preplanning. Figure 3.14 based on research by hman (1963), shows the position of the tongue at the moments marked by arrows on the accompanying spectrograms. The position and shape of the tongue at the time we hear the stop consonant d is different for various vocalic environments. The same is true of the palatal stop g.

实际利用X光来测试说话的样子，显示出发音前置动作的重要，图表3.14根据hman (1963)的研究，利用有箭头标记的光谱图，来展示每个时间点下舌头的位置，当我们听到塞音子音/d/的时候，发音者的舌头位置和形状与其他母音的发音环境有很大的不同，发出上颚塞音/g/的时候亦是如此。

Surface morphology, microstructure and wear morphology of the coatings were investigated using model KYKY-2800 scanning electron microscope modeled. Phases of the coatings were analyzed using model D/max-RA X-ray diffractometer. Microhardness of the coatings was tested using model MH-6 hardness-testing device. The wear-resisting property of coatings was compared with 65Mn steel treated by the quenching and backfiring technology using the home-made abrasion machine. The feasibility was analyzed for reactive electric-spark build-up welding TiN cermet coating to be used for gear shaft restoration.
