Experiment results show that the mechanical-thermal noise coming from the structure and the mechanical performance of a heavily doped Si membrane is the main noise of the device, which can be reduced by minishing the membrane area and extending the membrane thickness to increase the mechanical resonant frequency of the membrane, but should be at the price of reducing the sensitivity of the device.

Hz(上标 1/2)/W。实验表明，器件的噪声中热机械噪声为主要噪声源，大小主要由浓硼硅薄膜的机械性能和器件结构决定，可以通过增大薄膜厚度，减小薄膜面积，从而增加薄膜的特征频率的方法来减小器件受外界振动的影响，但以降低器件的灵敏度为代价。

管胞细胞壁纵向力学性能的影响因素： 11实验和理论计算均表明，S〓层微纤丝角是管胞纵向力学性能的决定性因素，微纤丝角越小，管胞的纵向弹性模量和强度越大。

Methods:The MSCT datas of 65 mechanical intestinal obstructions confirmed by operation and pathology were collected and reconstructed with multiplanar reconstruction technique,including 43 cases underwent plain scan;the remaining 22 cases underwent plain and contrast-enhanced scan.Results: Contrast to operation and pathology,there were 25 adhesions,24 neoplasms,5 bowel torsions,5 bezoarhs,4 intussusceptions,2 Crohn's diseases in 65 mechanical intestinal obstructions,the diagnostic accuracy of MPR in mechanical intestinal obstruction was 100%,and the accuracy of the pathogeny was 84.6%.

以往在肠梗阻的诊断中应用最多的为腹部X线平片，但因其信息量不足，对大部分病人不能提出肯定诊断，且对梗阻的病因及病变肠管的血供都无法判断。16层螺旋CT在肠梗阻的诊断中具有明显优势，快速、薄层扫描可得到高质量的各向同性后处理重建图像，在显示肠壁、肠腔和周围结构等方面具有较大优势，有利于肠梗阻的梗阻部位及病因、并发症的诊断。

Secondly, in spite of the reliability of software and control system, the mechanical system reliability of automatic yarn evenness tester is researched using FTA, and fault trees of each unit and system are established by analyzing its structure and function. According to system reliability theory and events probability, the mechanical system fault tree is analyzed by means of qualitative analysis and quantitative calculation, the system weak parts are found , and the ways are put forward to improve the mechanical system reliability.

其次，在不考虑软件及控制系统可靠性的情况下，利用故障树分析的方法，对全自动条干仪机械系统可靠性进行了分析研究，通过对其结构、功能的分析，建立了单个单元的故障树和系统的故障树；并根据系统可靠性的原理和事件发生的概率，进行了定性分析和定量计算，找出了系统的薄弱环节，提出了提高机械系统可靠性的途径。

This paper briefly reviews the operation principles and features of mechanical sight, optical sight, electrooptical sight and integrated sight. The status of mechanical sight, traditional optical sight, lowlightlevel night vision sight, new electrooptical sight and integrated sight equipped in different nations worldwide is given. The development status and parameters of various typical electrooptical sights as well as simple day and night firecontrol systems are described. It is pointed out that mechanical sight and optical sight are still necessary for future light weapons. However, electrooptical sight shall prevail in equipment procurement, and light weapon sight equipped in the future shall be the integrated electrooptical sight.

概述了机械瞄准具、光学瞄准具、光电瞄准具和综合瞄准具的工作原理和特点，介绍了目前世界各国装备的机械和传统光学瞄准具、微光夜视瞄准具、新型光电瞄准具、热成像瞄准具和综合光电瞄准具的现状，给出了各类典型光电瞄准具和昼夜简易火控系统的发展状况和参数，指出目前及今后机械瞄准具和光学瞄准具仍然是轻武器装备不可缺少的配置，不同类型光电瞄准具是装备的重点，综合光电瞄准具是轻武器瞄准具以后发展的方向。

Therapeutic horseback riding have been believed as a good media to improve balance ability. We proceeded to do a case study, by the use of a mechanical horse made by Joba EU-6441, Matsushita Electric Industrial Co., Ltd., Japan. This mechanical horse is designed according to the movement pattern of a real horse. The seat is designed to move in a pattern based on the figure of eight. Many clinics begin to adopt the mechanical horses as treatment tools, but its effectiveness in children with ADHD remains unknown.

目前对於ADHD儿童平衡能力的训练及介入成效之研究较少，本研究以骑马治疗进行个案讨论，采用的骑马机(Joba EU-6441， Matsushita Electric Industrial Co。， Ltd。， Japan)是根据真实马运动时的动作模式所设计出来的，临床上认为骑马机有可增进平衡能力的功用，目前已逐渐被临床治疗师广泛使用，但对於骑马机的确切疗效仍没有研究加以证实，尤其是骑马机是否对於平衡能力或是感觉调节能力有所帮助等。
