At the same time, some defects are pointed out: present fabrics are not properly applied, and most of looms can't produce woven perform whose property is similar in different directions. Their shearing strength are lower, utilization of mechanical properties are also smaller;Although three-dimensional braided composites is of excellent integrated structure, normal braided fiber is traveled from internal to external surface, which is passed through braider and becomes three-dimensional structure. If the external surface is cut or rubbed , it's possible for the fiber to break down. In addition , the shape of perform is easily changed after it's finished . To deal with respective shortcomings and highlight their own advantages, we're searching a new weaving method which is the combination between weaving and braiding .

但它们各自也具有许多缺点：目前机织物适应性不够，大多数织机还不能加工三维各向同性的机制预型件，材料剪切性能较低，力学性能利用率低；三维编织复合材料虽然具有良好的结构整体性，但常用的编织都是纤维从内表面穿到外表面，即穿过编织件的断面成三维结构，用这种方法制成的结构，如果外表面受到摩擦或切割损伤，就有可能导致结构的解体，此外编织结构的织物易变形，所以我们需要考虑一种新的结构，能同时发挥各自优势，又能同时克服二者缺点，这就是机织与编织结构相结合的方法。

The anterior clinoid process and roof and lateral crista of optic canal were drilled off intradurally to display proximal angle of the aneurysm in the cases of paraclinoid aneurysms.

术中采用逆向抽吸法使动脉瘤塌陷，如动脉瘤内含机化血栓，则在临时阻断后切开瘤体，用CUSA和取瘤镊去除瘤内血栓，再将动脉瘤夹闭并达到视神经减压的目的。

Objective To compare the changes of the number of the blood cell and coagulatory functions in the intracavitary blood before the use of Autologous Blood Recovery System and after.

The Grafting automatic machine is the cucurbitaceous vegetables which seedling in nutritional bowl.. It solves a difficult problem in vegetables' grafting., therefore, has high value for use in vegetable production.

本次设计的自动嫁接机针对的是采用营养钵育苗的葫芦科植物，实现了砧木苗在营养钵内无需拔苗即可直接的操作，有助于嫁接以后苗的恢复，在生产中具有较高的使用价值。

Software, and simulated by Monte Carlo method. The simulation results are conducted by descriptive statistics. Two "drop-in" assembly design lens groups were studied to calculate the stack-up element tilt and decenter within a cell and the resultant deviations of the optical axes away from the mechanical datum axis. The results indicate that the opto-mechanical tolerance model can analyze the critical to quality parameters of a lens system. As a result, the performance of the lens system can be anticipated by the opto-mechanical tolerance model before mass production.

戊n体编辑，并以蒙地卡罗方法模拟，模拟结果以叙述统计呈现；最后以两个&投入式&组立设计的镜群组为案例，计算镜片在镜筒内的累积偏心角度公差、偏心距离公差及镜片光学轴的累计偏移量，其结果显示该模型可模拟一个镜头系统的关键品质参数；所以，镜头系统的性能在大量生产之前可藉本光机公差模拟模型预测其品质与良率。
