The author hold that the academic science is related to the development of so-called mode theory which is used to approve the relation between universal phenomena, while the applied science is connected with how to apply the universal law of the academic science to the practical events in existence and enhancing the human control over the environment, which may lead the development of new technology, new method and new machine.

作者认为，理论科学主要涉及那些一般称为模式的学说的发展。这些学说是用来证实宇宙现象之间的关系。另一方面，应用科学则直接关系到如何把理论科学的通用定律应用到生活的实际事物中去，应用到加强人类对环境的控制上去，从而导致新技术、新方法和新机械的发展。

The main contents of this paper is used in college to learn the theory of the mechanics, control theory, mechanical design and computer programming technology, and mechanical theory to simulation, including through the establishment of two parts, kinematics and dynamics of the theoretical models (including Straight leg with the knee model and the model), the use of simulation software to achieve the whole process of Walkabout sports simulation, and to study the mass center position, slope angle and other parameters of walking gait characteristics of the device, and to find the law of passive walking, in order to further less energy-consuming research to lay the foundation of the robot.

本文的主要内容就是运用在大学期间所学到的理论力学、控制理论、机械设计以及计算机编程技术，进行理论推导和力学仿真，通过建立包括运动学和动力学两部分的理论模型的（包括直腿模型和带膝关节模型），利用仿真软件实现行走器整个过程的运动仿真，并研究质心位置、斜面倾角等参数对行走器步态特征的影响，从而找出被动行走的规律，为进一步研究耗能少的机器人奠定基础。这一段翻译成英文拜托别用在线翻译那种很多都是错的

However, the manufacture process of TWT is so complicated that many kinds of subjects, such as electron optics, magnetics, cathode electronics, microwave electronics, electromagnetic fields theory, material science, mechanics and calorifics are involved in.

行波管的研制涉及到电子光学、磁学、阴极电子学、微波电子学、电磁场理论、材料学、机械与热分析诸多学科，工艺过程十分复杂。

Objectives A rat model sciatic nerve crush injury was reproduced in rat, and behavioral changes, pain threshold, thermal withdrawal latency and the changes in c-fos expression in cornu dorsale medullae spinalis were examined, and the relationship between peripheral nerve regeneration and hyperpathia was explored.

目的 建立大鼠坐骨神经挤压模型，观察其神经恢复过程中行为学、机械痛阈值、热缩足反射潜伏期以及脊髓背角c-fos表达（对c-fos表达产物：Fos蛋白阳性的神经元进行计数）的改变，探讨外周神经损伤再生与痛觉过敏的关系。

The text is start at the need of practical manufacture, then formulize all the process of design and manufacture the Cleaning Machine of Nickel Anode Plate, including design scheme, program projection, draw detail drawing, elaborate and equip parts, assemble equipment, arrangement of wires and debug system. Comprehensive use many theoretics and knowledge, such as mechanical equipment design, CAD technology, Programmable Logical Controller, mechanical system simulation and other applied softwares. The final aim is design and assemble an armamentarium that can clean the anode mud on the Nickel Anode Plate.

本文以满足实际生产需要为出发点，阐述了镍阳极板清理机设计和制造的全过程，包括出方案、规划设计、绘制零件图、零件加工装配、设备安装、布线及调试，综合运用了机械装备设计、CAD技术、可编程控制器、系统仿真学以及一些应用软件的理论和知识，最终目标是设计并安装制造一套清理阳极泥的机电设备。

If only have the homiletic lessons on the classroom, it is easier make students feel baldness and difficult to learn, thus it go against to encourage the students with learning enthusiasm.

机械专业课是实践性很强的专业课，若在教室里以说教的形式进行教学，容易使学生感觉枯燥、难学，不利于调动学生的学习积极性。

DH level, CD4+ T lymphocyte count below 100 × 106/L, and interstitial pneumonia or ground-glass shadow in chest images, the diagnosis of PCP could be made presumptively. It is difficult to make a nosogenic diagnosis of PCP, but TBB considerably increases the positive rate of pneumocystis. Compound sulfamethoxazole is recommended as the first selected drug. In severe cases, corticosteroid and assisted mechanical ventilation combined with compound sulfamethoxazole could remarkably improve the prognosis of PCP.

当AIDS患者出现发热、咳嗽、呼吸困难、低氧血症、LDH增高及CD4+T淋巴细胞＜100×106/L时，结合胸部影像间质性肺炎或磨砂玻璃样改变，临床需考虑PCP；病原学诊断困难，但TBB肺孢子菌检出率高；治疗首选SMZ-TMP，重症病例辅以糖皮质激素和机械辅助通气可改善预后。
