Results Compared high kV X-ray chest film with spiral CT,to simplex silicosis,X-ray films coincided with CT scans;to mixed silicosis,the effect of CT scans were better than X-ray's;to large nodule,coalesced progressive massive fibrosis,the detected ratio of CT scans were higher than X-ray chest films;to silicosis complication,for example,emphysema,pleural thickening,phthisic,mediastinal impairment lympy node etc,CT scans were more reliable than X-ray films,especially HRCT can earlier find silicotic nodule and fine structure of focus.Selective application of CT scan,had great diagnostic value in complicated silicosis and silco-tuberculosis and lung cancer complicated with silicosis etc.

结果 高千伏X线胸片与螺旋CT作对比，结果对单纯矽肺并发肺癌，CT片与X线胸片基本一致；对于复杂矽肺并发肺癌CT优于X线胸片；对于大结节、肺内进行性大块纤维化(progressive massive fibrosis，PMF)融合、空洞及钙化CT检出率明显高出胸片；对矽肺并发肺癌的合并其他如肺气肿、胸膜肥厚、结核、纵隔淋巴受累等CT均较胸片可靠；特别是HRCT能早期发现矽肺肿块样病灶中细微结构，选择性应用CT，对复杂矽肺并发肺癌合并结核等鉴别诊断有很大价值。

In recent years, although multichannels (more than 256) gamma ray spectrometer has been made overseas, field gamma ray spectrometric survey is only used to determine contents of uranium, thorium and potassium, by reason of applying gamma ray spectrometry later than developing instruments, can't obtaining full spectrum because of the problem of stabilizing gamma ray spectrometric peaks, and it is impercipient for field gamma ray spectrometry.

作者分析了国内外野外地面伽玛射线全谱测量存在的问题主要是：（1）目前国内外野外地面伽玛能谱测量中主要使用四道能谱仪，仅利用能量大于1000keV的伽玛射线，通过数个谱段的读数结果，计算铀、钍、钾的含量，而没有利用伽玛射线全谱，使80％以上的伽玛射线能谱信息摒弃未用。

The annual variation of each meteorological parameter likes cosmic ray flux. There is obvious correlation existing between cosmic ray and each meteorological parameter. After the meteorological effect of cosmic ray being corrected by using multianalysis, there is no annual variation of cosmic ray.

论文还对1994-2004年间的气象数据进行了整理分析，气压、室内温度、室外温度与宇宙线触发率有着相似的年变化，存在较强关联；之后对宇宙线触发率进行了多元气象参量修正，修正后的宇宙线触发率不再有明显的年变化。

And then, a window-type novel x-ray crystal spectrometer was put forward based on the elliptically curved crystal analyzer. It was coupled to an x-ray CCD camera, and a set of system had been designed and constructed. The spectrograph is useful in the experiments of x-ray diagnostics, for example in x-ray lasers, inertial confinement fusion, laser-matter interaction, and so on.

本论文从X射线晶体衍射和椭圆自聚焦几何光学原理出发，剖析追究了椭圆型弯曲X射线晶体谱仪在实际应用中产生问题的根源，率先从技术上提出解决目前椭圆型弯曲X射线晶体谱仪存在问题的思路，论证了其相应实施方案的可行性。

It consists of fitting seismic ray traveltimes and positions to data calculated by ray tracing. In order to improve inversion stability and efficiency, seismic ray is described by Hamilton function and ray tracing is done in phase space. Validation tests on synthetic and practical data are analyzed. The tests show that this tomographic method is effective for estimating velocity field in complex media.

为提高反演的稳定性和计算效率，引入了Hamilton函数描述射线，在相空间计算反演所需的射线路径和目标函数对模型参数的导数，对理论模型和实际地震资料进行了试算，试算表明该方法对复杂介质具有较强的适应能力。

Results In 7 cases of odontoid process fracture, X-ray demonstrated 4 cases and CT demonstrated 5 cases, whereas the spiral CT reconstruction diagnosed 7 cases, which could display the displacement of fracture clearly. The X-ray and CT showed asymmetric space between left and right gaps of atlantoaxial joint in 6 cases, while spiral CT reconstruction showed normal and excluded the possibility of atlantoaxial dislocation. There was one case of lateral atlantoaxial joint dislocation, which was demonstrated by the spiral CT reconstruction clearly but not by the X-ray and CT scan. There were 3 cases of atlantoaxial congenital deformity (1 case of absence of both posterior arch of atlas and odontoid process and 2 cases of maldevelopment of the odontoid process), which were displayed clearly by spiral CT reconstruction, but misdiagnosed as odontoid process fracture and atlantoaxial subluxation by X-ray and CT scan.

结果 7例齿状突骨折中，X线显示4例，CT显示5例，CT重建确诊7例，且清楚显示骨折移位情况；6例X线、CT显示寰枢椎左右间隙不对称，通过CT重建排除寰枢关节半脱位；寰枢外侧关节脱位1例，CT重建可清楚显示，而X线片和CT平扫均未能显示；寰枢椎畸形3例，分别为齿状突、后弓缺如1例，齿状突发育不良2例，CT重建均能清楚显示，而X线、CT均误诊为齿状突骨折、寰枢椎半脱位。

Ray depth specifies the maximum number of times a light ray can be reflected and, or refracted and still cause an object to cast a shadow . Transparent objects between those points in which the ray changes direction will have no affect on the light ray's termination.

光线跟踪深度决定了一个光线在让一个物体产生阴影之前，可以被反射或者折射的最大次数，在光线改变方向的点之间，透明的物体将不会对光线的终止产生作用。

Abstract］ objective to improve the diagnosis of non-ossifying fiboma by analysing its x-ray feature.methods plain x-ray films was performed in all patients.x-ray finding in 8 cases with pathologically-confirmed non-ossifying were analyzed.results the clinical symptom was mild,the lesions occurred usually at the metaphysis of the long bones,the affected bones included femur（n=4）,tibia（n=3）,humerus（n=1）.cortical type was seen in 5 cases,presenting as unilocular or multilacular transparent areas with in the cortex or tightly beneath the cortex,the lesion had a sclerotic margin.which was more obvious at the marrow side.medullary type was seen in 2 cases.the lesion was located at the center of the bone and grew centrally.the tumor was manifested as unilocular or multilocular.tramsparent area with sclerotic border and the bone cortex became thinner with slightly expanding on 11 sides.conclusion plain radiography is the elementally means to detect this disease.based on the typical x-ray signs of non-ossifying fibroma combined with clinical data,correct preoperative diagnosis can be made in most cases.
