颞骨鼓部

The characteristics of skull bones are; underdevelopment of paramostoid process of the occipital bone; unjointing of zygomatic process from its arch with no supraorbital foramen; formation of semiglobal structure by petrous temporal bone;no naso -maxillary notch between nasal bone and nasal process of premaxilla; unobvious facial surface of lacrimal bones;well-developed nasal process of premaxilla; no facial crest of maxillae's exterior;...

头骨的主要特征是：枕骨的颈交不发达，眶上突不与颧弓相连，无眶上孔；颞骨岩部形成半球形鼓泡，鼻骨与颌前骨的鼻突之间不形成鼻颌切迹；泪骨几乎无颜面部；颌前骨的鼻突发达；上颌骨外面无面嵴；腭骨发达；犁骨腹缘后部不与鼻腔底壁接触；下颌骨支下缘无血管切迹、垂直部后下方有一角突。

Methods Twenty-two pieces of temporal bone were taken for this study. The mastoid cavity was opened, scutum removed,"bridge" broken down, posterior wall of external auditory canal abraded and the related anatomic structures were fully exposed. The distance between the origin of facial nerve canal and the anterior border of round window （ OOFNC-ABORW ）, between the highest point of the facial nerve canal and the bottom of posterior mastoid sinus,and between the stapes head and round window niche was measured under operating microscope.

方法取成人颞骨22侧（左右各11侧），用耳科钻磨开乳突腔，去上鼓室盾板、断"桥"，磨低骨性外耳道后壁，充分暴露相关结构，在手术显微镜下测量面神经管垂直段起始部前缘至圆窗龛前缘的距离、面神经管最高点与后鼓室底壁之间的距离、锥隆起的高度（即锥隆起基底到锥隆起顶端的距离）、镫骨头至圆窗龛前缘的距离。

Temporal bone fracture occasionally occurs, but a pure fracture of tympanic portion of the temporal bone is less common.

颞骨骨折并不罕见，但是单纯的颞骨鼓室部骨折则不常发生。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
