Lid done with stainless steel plate floor, built-silicate insulation, Furnace Door size 350 mm wide, 580 mm high, the overall lateral wall elevate electric holding furnace door, Furnace Door closure of the Furnace Door as a whole round , Furnace Door sealing performance enhancements, dial made of stainless steel by 1600 m / m turntable, used to load the workpiece, the entire wheel of the plane is not division, the operator can be stacked workpiece, as dial-rotation every 40 minutes a week , when the operator can not see dial in almost rotation, and Furnace Door open the larger operators can be arbitrary and out of the workpiece, and without time limits can dial in 20-60 minutes a week to arbitrary rotation speed, regardless of Furnace Door hoist, from the start of work on the dial continuous rotation, and there was no need for chain hoist Furnace Door, the need to stop rotating, just press the control cabinet, stop button, the gate Furnace Door, operators to seize its own, activated installed in the furnace door open and close button.

炉盖采用不锈钢板做底板，内置硅酸铝保温，炉门尺寸宽350mm，高580mm，侧墙体中整体向上提升式电动保温炉门，炉门关闭时整个炉门为一个圆形整体，炉门密封性能增强，转盘采用不绣钢制成1600m/m转盘，用以承载工件之用，整个转盘为平面不分工位，操作人员可以任意堆放工件，由于转盘每40分钟旋传一周，工作时操作人员几乎看不到转盘在转动，加上炉门开的较大，操作人员可以任意进出工件，而不受时间限转盘可以在20--60分钟旋转一周的时间任意调速，不论炉门启闭、转盘从启动工作就不间断的旋转，没有任何必要与炉门启闭进行联锁，需要停止旋转时，只需按下控制电柜上的停止按钮即可，炉门的启闭，由操作人员自行掌握，按动安装在炉门边的启闭钮即可。

RESULTS: Cells were spindle shape before induction, obviously varied following preinduction, and then the body began contracted after being induced in the medium for 1 hour, with the presence of a few small orbicular-ovate or spindle cells. Following 24 hours of induction, about 60% cells became double pole, multipolar or cone shape, showing neuron-like structure.

结果：①诱导分化前呈梭形细胞，在加入预诱导培养基后未出现明显的形态变化，换用诱导培养基1 h，胞体开始收缩，出现少数较小的卵圆形或纺锤形细胞，诱导24 h后，约60%细胞变成双极形、多极形和锥形，出现类似神经元细胞的形态。

In this thesis, terahertz transmission properties through three kinds of simple sub-wavelength metallic structures, including single sub-wavelength metallic circular hole, single sub-wavelength metallic slit and double sub-wavelength metallic slits, are experimentally investigated in the far field by using our own THz time-domain spectroscopy system and are theoretically analyzed. Conclusions are obtained as follows:(1) a single sub-wavelength metallic circular hole exhibits the same terahertz transmission properties as that of round metallic waveguide, which are influenced by the diameter of circular hole and the thickness of metal foil.

本文利用本实验室搭建的太赫兹时域光谱系统研究了太赫兹波段金属亚波长结构的透射特性，其中对三类金属亚波长简单结构即单个金属亚波长圆孔、单个金属亚波长狭缝和金属亚波长双缝的太赫兹透射现象进行了远场探测以及理论上的分析，得到了以下一些成果：(1)太赫兹波通过单个金属亚波长圆孔的传播现象与圆形金属波导具有相同的规律，其特性受到圆孔直径和金属箔厚度的影响。
