When the moment made by material on turning plate is greater than that of heavy hammer and rocker, the disc will open adown to discharge. After discharge the moment made by heavy hammer and rocker will drive disc close quickly to realize locking air. Because the structure of valve is two-layer, there is always one disc in pipe that is in close condition. So it can discharges and lock air at the same time.

即当作用于翻板上的物料产生的力矩大于重锤摇杆产生的力矩时，阀板打开卸灰，一旦积灰卸去后，重锤与摇杆产生的力矩使阀板迅速关闭，实现锁气是由于本阀采用的是双层结构，因而使管道上阀板始终有一个是关闭状态，可使卸灰与锁气同时达到目的。

Selected anastomosis site:The site for the attempt at anastomosis creation was chosen at least 2-3 disc diametersaway from the optic disc or 1 disc diameter peripheral to the occlusion site in eyes with bruch retinal vein occlusion, and a large underlying choroidal vein by showing in ICGA, usually in the inferior fundus.

激光吻合：在选定的吻合部位，用选定的高能量激光先击射邻近的＊＿Ch膜，接着是静脉壁本身，Bruch膜破裂的疑似迹象，为一汽化泡，当静脉壁破坏时有微量的出血。37例RVO共做了86个吻合点，所用的激光参数为：光斑直径50p，曝光时间 0.l秒，使用绿光最多 63个点（72％），功率 800～900mw，少数用氟红、氟黄及Nd：YAG激光。

Methods: Forty-five SD rats were divided equally into SMT group, cervical intervertebral disc cataplasia model group and normal control group. Three months later, the morphologic changes of intervertebral disc were observed to determine the proteoglycan contents and the apoptosis rate of the intervertebral disc cells.

选取8月龄雌性SD大鼠45只，随机分为实验组、实验对照组和正常对照组，实验组和实验对照组分别造颈椎静动力平衡失调模型，实验组腹腔注射SMT.3个月后光镜下观察椎间盘形态，测定蛋白多糖含量及椎间盘细胞凋亡率，并比较。

In co-revolution disc cavity, heat transfer coefficient which is high on most region of disc surface show that the co-revolution avails the heat transfer on disc surface.

但在出口处出现大面积"倒流"，盘腔外端的温度较高，这与流动参数和出口面积的大小有关，有待进一步研究。

Disc assembly. Disc is fastened securely to disc hanger with a lock nut and cotter pin.

阀瓣总成。通过一个锁紧螺母和开口销将阀瓣安全紧固在阀瓣支架上。

The results indicated that the centrifugal force reduces the localization; when the Young's modulus of all blades are in the tolerance of 5%, the blade-disc can regarded as an cyclic symmetry system. The study results given in the present paper have provided a variety of effective numerical methods for the study of vibration characteristics of blade, disc and the blade-disc system. These research results can also serve as a helpful guide to the vibration study of other rotating components.

本文的研究成果为汽轮机关键部件叶片—轮盘系统的振动特性研究提供了一些有效的数值方法，得到了一些结论，对工程具有较大的现实意义，同时对其他叶轮机械旋转部件的振动研究也有参考价值。

After finished the drawbar spring disc alignment then fix the spring disc stopper, and turn in let the spring disc total length to the standard length (114pcs about 277mm), then the drawbar top fix the M16x1.5 nut.

连接杆弹簧圆盘调整成一直线，然后固定弹簧圆盘的止动块，使之总长为标准长度（114个约277mm），再在连接杆顶部固定M16x1.5的螺母。
