Objective To observe the changs of cochlear hair cell induced by large dose cephazoline in iron-deficient New Zealand white rabbit.

目的 观察大剂量头孢唑啉在铁缺乏条件下对新西兰大白兔耳蜗毛细胞的影响。

Objective To count the number of ribbon synapses in cochlear inner hair cell using three-dimensional reconstruction model.

目的利用三维建模的方法对耳蜗内毛细胞带状突触进行计数分析，解决由于内毛细胞带状突触数量少、位置深在造成的计数困难，为内毛细胞带状突触的可塑性研究提供有效可靠的计数方法。

With the rapid development of diagnostic audiology, there comes more and more audiometries. Though advanced electrophysiology audiometry takes a prominence place in clinical and rehabilitation audiology, behavioral audiometry has its unique advantage, which electrophysiology audiometry cannot supercede. Thus, behavioral audiometry runs through the process of the recovery of deaf children, not only in the diagnose of pediatric auditory loss, also in the hearing-aid threshold obtaining and the adjustment of artificial cochlea.

目的 行为测听技术有其独特的优势，有着电生理测听技术不可替代的作用，在临床听力学特别是聋儿康复过程中贯穿始终，不但用于小儿听力损失的诊断，在小儿助听听阈获得及人工耳蜗调试中起着重要作用。

The basic worm helicoid surface of sphericity hob was deduced, and the coordinate systems for cutting face gears were established.

推导了球形滚刀基本蜗杆螺旋面方程，建立了滚切面齿轮的坐标系统。

Furthermore,we verify the good contact state with section diagrams in the virtual reality entity of the involute helicoid double enveloping worm gear pair.

The sections were stained by hematein、eosin and immunohistochemistry. The morphology of the tissue sections was observed.

取1天龄大鼠、成年豚鼠、成年小鼠耳蜗标本经蔗糖快速浸透，用离心管定向并用新型组织包埋剂Tissue-Tek包埋，液氮中快速冷冻后在恒冷箱切片机中切片，然后分别做苏木素、伊红染色和免疫组化染色，观察组织切片的形态结构。

The pressure field and the velocity field in a cyclone separator were measured with five-hole probe and hot-wire anemometer respectively.

用五孔探针和热线风速仪测定了蜗壳式旋风分离器内的速度场和压力场，分析了上部入口结构、芯管插入深度和锥体长度对流场的影响。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
