Eagle's type has very much, for example: Big spot vulture, condor, black yuan and so on The eagle and the common birds are a little different, the eagle belongs to the animal class, The common birds belong to the omnivora animal, not too same, This is the experienced bird height 56 centimeter, the chord approximately 417-465 centimeter, the body weight approximately 630-1030 gram, egg 2-5, Bai De has the reddish brown spot approximately, sits on eggs contract 38 day,…A thorough material eagle secondary next four, five small hawks, because their lair is very high, hawk and common birds' difference The eagle for black yuan in Taiwan's popular name, the Taiwanese calls Ye Huoli the wing.

老鹰的种类有很多，例如：大斑鹫、秃鹰、黑鸢等欢迎来到本站，老鹰和一般鸟类有点不同，老鹰属於禽兽类，一般鸟类属於杂食类的动物，不太相同，这就是老成鸟身长约56公分、翼长约417-465公分、体重约630-1030公克、蛋2-5个，白底有红棕色斑点、孵卵期约38天、。。。深入资料老鹰一次生下四、五只小鹰，由於它们的巢穴很高，鹰和一般鸟类的不同老鹰为黑鸢在台湾的俗称，台语称来叶或厉翼。

Methods: The expression level of NOS and NGF was detected in pterygopalatine ganglion of the allergic rhinitis rats using histochemieal and immunofluorescence staining methods respectively.

建立AR大鼠模型，用HE染色方法观察鼻黏膜内腺体的变化；用组织化学的方法观察翼腭神经节内NOS表达的变化；用免疫荧光的方法观察翼腭神经节内NGF表达的变化。

There were two layers of tissue in the pterygopalatine fossa,they are posteromedial nerve layer and anterolateral vessel layer.The distance from the internal carotid artery to the sphenopalatine foramen was 16.4±3.3 mm.

结果：蝶腭孔、圆孔、翼腭裂距离前鼻嵴的距离分别为(62.3±2.7)、(64.2±4.8)、(51.5±0.6) mm，翼腭窝内的结构可以分为在后内的神经层和在前外的血管层，颈内动脉与蝶腭孔之间的距离为(16.4±3.3) mm。

Low pulse before sift network operating principles : the use of double - sieve drum aircraft design; Work, pulp before sift upper tangent pressure the network into; Pulp the filter into the upper body of the dle two filter drum, double tilt-rotor rotary rotors, while the centrifugal force and centripetal forces role, through good mix inside and outside pool in sieve sieve drum body low extremity good mix of outflow; pulse in the tilt-rotor rotary drum filter

低脉冲网前筛工作原理：该机采用双筛鼓设计；工作时，浆料从网前筛上部切线压力送入；浆料从筛体上部流入到两个筛鼓中间，在双旋翼转子旋转时产生的离心力和向心力的同时作用下，良浆通过内、外筛鼓汇集于筛体下端的良浆管流出；脉冲旋翼在旋转时筛鼓不会赌赛，浆渣受转子旋转产生的轴向推动力，向下流送的同时被浓缩并逐步移到排渣口。
