When reached logarithm growth phase, it was poured or the medium was removed. 5 mL medium containing 10 mg/L mitocin-C was added , kept at 37 ℃, and then cultured in saturated humidity warm box with the CO2 of 0.05 fraction volume for 2 or 3 hours. It was coated with 0.1% gelatin in 6-hole plate, laid for over 30 minutes, and then threw away or the medium with mitocin-C was removed, washed with phosptat buffer for 5 times so as to remove the mitocin-C. 2 mL 0.05% trypsin digestive cells were added, and it was observed under microscope. When crevice appeared, cells became round (about 2－4 minutes), digestion was stopped by adding medium of the same volume, and blew up with straws repetitively to make it into monoplast suspension. Special-used cover glass was put in the center of cell counting chamber. Cells were sucked in by glass siphon, and cell suspension flew out at bucket of up or down-sides of counting chamber, until the cover glass was filled with fluid. Living cell were inoculated at concentrations of 3×108, 5×108, 1×109 L－1 after their number counted.

选取2～5代的小鼠胚胎成纤维细胞，待其至对数生长期倒掉或吸掉培养基，加入含10 mg/L丝裂霉素C的细胞全培养液5 mL，置37 ℃，体积分数0.05的CO2饱和湿度温箱中培养二三小时，在6孔板中加入0.1%明胶包被，放置30 min以上，倒掉或吸掉含丝裂霉素C的培养基，磷酸盐缓冲液清洗5遍，尽量除去丝裂霉素C，加入2 mL 0.05%的胰蛋白酶消化细胞，镜下观察，当细胞间出现裂隙，细胞变圆时（约2～4 min），立即加入等量的全培养液终止消化，并用吸管反复吹打，使之成为单细胞悬液，在细胞计数板中央放置专用的盖玻片，用玻璃虹吸管吸取细胞，让虹吸管在盖玻片上或下侧的计数板凹槽处流出悬液，至盖玻片下被液体充满为止。

First, second and third position sensor controllers control the focus servo to focus the He--Ne laser beam on the glass substrate in response to the pit width of the glass substrate by sensing the laser beam for focusing reflectedupon the glass substrate.

此聚焦系统利用第一、第二、第三光点位置敏感器去控制氦一氖雷射，使其能够在玻璃基板上产生正确的凹坑宽度，而第一、第二、第三光点位置敏感器即藉著聚焦在玻璃基板上反射而回的氦一氖雷射作为聚焦控制。

The arrangement of braces is X type. The braces is H175x175x11x7.5, same as the second test of TCBF. Because of additional knife plates, the braces length in this test is a little shorter than the second TCBF test. The gusset plate design use the UFM instead of ellipse bending design method.

试体高6.66公尺，宽6.7公尺，斜撑排列形式为大X形，斜撑尺寸为H175x175x11x7.5，与第二次TCBF试验采用之斜撑相同，但本研究因需配置额外的连接板而使得斜撑长度略短，接合板则采用规范建议之UFM进行设计，与第二次TCBF椭圆形凹折设计不同。
