The raw data was processed by using axial, coronal and double oblique multi-planar reformation; Images obtained were graded in terms of quality with a 5-point scale(5=excellent, 4=good, 3=fair, 2=poor, and 1=nondiagnostic). In grading image quality at axial MPR, The radiologic specialists focused on the subarcuate fossa, tendon of tensor tympani, facial recess, vestibular aqueduct and pyramidal eminence, In grading image quality at coronal MPR, attention was given to the scute, crista transversa, fenestra cochleae, lateral malleal ligament and snake eyes signature of cranial nerve, In the grading of the image quality at double oblique MPR, the radiologic specialists concentrated on the malleus, incus, stirrup bone, upper bony semicircular and aquaeductus fallopii, and then to implement statistical analysis. In order to choose the minimum tube current values and the maximum pitch that can satisfy the diagnosis request, image quality of axial, coronal and double oblique reformation images was compared with different tube current groups. 15 ears of volunteers were used to test the validity with the scanning parameter. Subsequently noise, MTF and dose length product were measured by phantoms in different tube current and pitch, the parameters obtained were compared and taken into statistics analysis.

扫描模式使用临床常用的颞骨螺旋扫描方式：管电压120 kV，准直宽度20×0.6 mm，视野200 mm，重建矩阵512×512，旋转时间1 s/r，重建层厚0.6 mm，重建间隔0.3 mm，分别改变管电流(380、300、200、160、120和80 mA)和螺距(0.8、1.0和1.2)进行扫描和重建，然后对颞骨进行横断面、冠状面和双斜面多平面重组，于重组后的横断层面图像上选取弓形下窝、鼓膜张肌腱、面神经隐窝、前庭导水管和锥隆起5个解剖结构，冠状面重组图像上选取盾板、横嵴、蜗窗、面神经的蛇眼征和锤骨外侧韧带5个解剖结构，双斜面重组图像上选取锤骨、砧骨、镫骨、上骨半规管和面神经管5个解剖结构，在双盲的情况下由放射学专家分别对各管电流和螺距下扫描的重组图像进行评分，随后进行统计学处理，从中筛选出满足诊断要求的最低管电流值和最大的螺距，分别采用患者25例(15耳)用该管电流值和螺距验证其可行性；然后利用模体分别测试各管电流和螺距下的图像的空间分辨率、噪声及其剂量长度积，并对测试所得参数数值进行比较和统计学处理。

The spiral CT can display the time phase strengthening of the artery and vein of uterus neck and its body,improve the blood vessel and treatment efˉfects so that it is easy to observe the blood supplying of the tumor and display its actual range;obtain the continuous thin layer picture;can display the changing form of the uterus neck through the cross section,arrow and coronary form,and distinguish the structure around the uterus and the symptom of the vagina infected,pelvis lymph gland and pelvis surface metastasis to confirm the stage of cervical carcinoma and find out whether the cervical carcinoma is reˉcurred after operation and the effect is good or not after the chemotherapy.

螺旋CT能显示宫颈和宫体的动脉期及静脉期强化时相，改善血管强化效果，利于癌肿血供情况的观察和显示癌肿的实际范围；获得连续的薄层图像；能从横断面、矢状面及冠状面显示宫颈形态改变，辨别宫旁结构，阴道受侵及盆腔淋巴结、盆壁转移征象，对宫颈癌的分期准确，了解术后有无复发及放疗效果。

Scalariform thickening A type of secondary wall formation consisting of interlaced helical bands of thickening giving a ladderlike formation. It allows for very little further extension, and is found in tissues such as metaxylem tracheids and vessels, which do not elongate after maturation.

梯纹加厚：是植物细胞次生壁的一种形态结构，壁由加厚过程中相互交错成梯状形态的螺旋带形成，其可延伸性很小，多存在于后生木质部管胞和导管等一些成熟后便不再延伸的管状分子中。

At 650 light-years away, the Helix is one of the nearest planetary nebulae to Earth.

With circumspection, as invariably when entering an abode: with solicitude, the snakespiral springs of the mattress being old, the brass quoits and pendent viper radii loose and tremulous under stress and strain: prudently, as entering a lair or ambush of lust or adders: lightly, the less to disturb: reverently, the bed of conception and of birth, of consummation of marriage and of breach of marriage, of sleep and of death.

645谨慎地，就像每一次进入一座房子（他自己的或并非他自己的）的时候那样，小心翼翼地，因为床垫子那蛇状螺旋弹簧已经陈旧了，黄铜环和蝰蛇状拱形挡头也松松垮垮的，一用力过头就颤悠；顾虑周到地，就好像进入肉欲或毒蛇的巢穴或隐身之处似的；轻轻地，省得惊动她；虔诚地，因为那是妊娠与分娩之床，合卺与失贞之床，睡眠与死亡之床。

Generally,it is considered that cotton fibre is a column and its surface is smooth.The surface structure of Xinjiang long fine hair cotton is researched by using electronic microscope scanning (S-570 Japan).The result shows that the cotton fibre is not a column,but is spiral.The fibre of only 15%does not twist.The surface of the fibre is not smooth,and there are burrs on it.These characteristics would be another important factor effecting the stickability of cotton.

一般认为，棉纤维呈圆柱状，纤维表面是光滑的，笔者以新疆长绒棉为研究对象，用日立S-57日扫描电镜，研究了棉纤维的表面结构，结果表明，棉纤维并非呈圆柱状，自然状态下呈螺旋形，象氨基酸那样，根据概率估计，没有扭曲的约占15%，棉纤维表面并不光滑，有毛刺，这种结构特性是影响棉花粘着性的又一重要因素。

Spondylolysis were showed in sagittal images. Conclusion: The scan range were increased for the fourth lumbar to first sacroiliac interverteral disc and contained vertebral arch for conventional intervertebral disc. The spiral scanning were performed for lumbar spondyloschisis and with MPR along the direction of vertebral arch. The method is simple and useful for the patients suffered low-back pain.

对常规椎间盘扫描采用对L(下标 4~5)及L5~S1，椎间盘加大扫描范围，包括椎弓根层面的方法，对于轴位扫描发现或可疑峡部裂的患者再做相应椎体螺旋扫描，行平行于峡部的椎弓长轴多平面斜矢状面和矢状面重建，是腰腿痛病人CT检查的简单、实用的有效方法。
