Results In 36 patients,CT was useful for the diagnosis of fracture,subarachnoid hemorrhage and multiple brain contusions,but missed 2 patients with brain contusion,5 patients with axis cylinders injury and 1 patient with subdural hematoma.MRI was more sensitive compared to CT with a miss of 3 patients with fractures,1 patient with axis cylinder injury and 4 patients with subarachnoid hemorrhage.

结果 36例中，CT对骨折、蛛网膜下腔出血及多发脑挫裂伤显示较好，但漏检2例脑挫裂伤、5例轴索损伤和1例硬膜下血肿；MRI病灶检出率较CT高，但MRI有3例骨折、1例轴索损伤和4例蛛网膜下腔出血不能检出。

In a rectangular shape YBCO singledomain sample, there are many long, smooth and parallel growth stripes on the top surface, which indicates that the ab plane is parallel to the axis of the cylinder sample, the long narrow and smooth stripes are formed by the continues growth along a axis.

在ab面竖直生长的YBCO晶体中，样品表面光滑、平行的长直条纹是晶体沿ab面连续生长的结果，沿c轴方向的平行台阶，则是晶体沿c轴方向以层状方式生长所形成的，十字线夹角约78°。

Methods(1)4 cities were chosen randomly according to their economic status and geographical location.(2)An autorefractor was used to detect the diopter in the preschool children from 20 kindergartens randomly selected from each of the 4 cities.(3)1%atropine ointment was applied to the c onjunctival sac of the children with suspect myopia for 3 days and the refractio n of light in their retina was then examined by a barred beam skiascope.(4)The eye axis and corneal curvature of the myopic children were measured.(5)The diop ter,eye axis,and corneal curvature were examined every 6 months during 1-year f ollow-up after the diopter was properly rectified.

(1)依经济状况和地理位置按随机原则抽取4市县；(2)从4市县中各随机选择20间幼儿园，对所抽取的在园学龄前儿童用自动屈光仪进行屈光筛查；(3)可疑近视患者予以1%阿托品眼膏涂双眼3d，由专人用带状检影镜进行视网膜检影验光；(4)确诊为近视的患者自愿进行角膜曲率和眼轴测量；(5)近视患者经适当的屈光矫正后，按要求进行为期1年的前瞻性随访，每半年进行1次屈光状态、角膜曲率和眼轴的检测。

According to the features of images, methods such as peak, axis of projection and area volume analysis were proposed to use in the study of myocardial infarction.

提出R-S积分法於影像平面中进行心轴角度计算方法，并说明修正加压单极肢导程对於心轴判读的必要性。

The axonometric projection has been applied extensively in engineering because of its three-dimensional effect and better measurement and because of its drawing unsophisticatedly.

从图形直观性和作图简便程度出发，阐述了在实际工程中怎样选择合适的轴测投影图表达实体，以及不同的专业领域选用不同种类的轴测投影图

An improvement has been carried out on the generation method of 2D engineering drawing from 3D model in AutoCAD, and formed an intact methodology and skill of generating axonometric drawing and multi-planed orthogonal projection drawing from 3D model.

对AutoCAD中由三维模型生成二维工程图的方法进行了改进，形成由三维模型生成轴测图和多面正投影图的完整方法和技巧，这种方法所得到的轴测图和正投影图，可以对其更加方便地进行各种编辑，是一种适用的方
