Results The distance from the anterior naris to the anterior wall of the sphenoid sinus was (65.36±3.58) mm and that to the bottom of the hypophyseal fossa was (79.18±3.71) mm.

结果 前鼻孔到蝶窦前壁的距离(65.36±3.58)mm；前鼻孔到蝶鞍底部的距离(79.18±3.71)mm；鼻后孔弓到颅底的距离(21.18±4.31)mm；后鼻孔弓到蝶窦开口的距离(13.22±3.36)mm。

The perpendicular line from neurocanal most lateral to the sa line and sb line were defined as h1 and h2 respectively,the length of Ph1 and Ph2 were measured,the diameter of screw smaller than 2 times of Ph2 lengths was regarded as safe.The line from the first posterior foramen lower end to the second posterior foramen upper end was obtained.

第一骶后孔下缘最低点与第二骶后孔上缘最高点连线为WY，平分椎弓根的平面与WY线的交点为O，测量WO的距离，O点在W的下方时为正值，O点在W的上方时为负值。

Results: On the normal sacrum, there was no difference between the left and right distance between the middle point of transverse line to sacrum wing, as well left and right transverse diameter of anterior and posterior sacral foramina.

Under the microenvironments of fruit bagging,Alternaria had always been the major fungi in different bags,sites of fruit and weather conditions during the whole growing season. As the secondary major fungi,Penicillium had always been after July and emerged later in inner bag and cortical pore than other sites.In the bag with which the inner bag was red and waxing,Trichoderma was isolated first in pericarp without cortical pore and inner bag as well as later in cortical pore after August.In \'Kobayashi\' bag which inner bag was red and waxing, Aspergillus and Fusarium were isolated in pericarp without cortical pore and cortical pore after bag removed.Alternaria and Penicillium were isolated in unbagging fruit and \'Qianwei\' bag which inner bag was red and unwaxing and the date Penicillium was isolated in CK was 45d later than bagging treatment.Under high temperature weather condition,there were no differences in the fungi population structure on fruit surface among all treatments.And the fungi population structure on fruit surface in bagging apple was more than that of unbagging ones under overcast and rainy condition.

在苹果套袋微域环境下，不同育果袋、果实不同部位、不同时期、不同气象条件下的真菌主要是链格孢霉，且在套袋后的整个生长季均可分离到；青霉为第二大真菌，在7月份后均可分离到，在非皮孔部位的出现要早于内果袋和皮孔部位；8月份后在内袋红色涂蜡的育果袋上分离出了木霉，其先出现在非皮孔处和内果袋，然后出现在皮孔处；曲霉和镰刀菌仅在内袋红色涂蜡的&小林&袋的非皮孔部位和皮孔部位于摘袋后分离出；在内袋为黑色且未涂蜡的育果袋和未套袋果上仅仅分离出链格孢霉和青霉，且青霉分离出的时期要比套袋果晚45d。

Objective:To improve the diagnosis and treatment level of choanal polyps of child.
