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。

This allows many pump fibers to be coupled to the main laser fiber so allowing more power to be pumped into the system without the use of free space optics, making a completely sealed and thereby highly reliable system, using these methods, almost any number of high lifetime diodes, each producing less than 10w of low quality diode light, can efficiently coupled into a fiber laser to produce hundreds of Watts of near perfect, focusable fiber laser light.

为产生更多的能量,制成一个完全密封的高可信度的系统,用这种方法几乎可制成任何数量的奈用的二极管,来产生小于10W 的低质量二极管光线,还可能效地附加到纤维激光机上来产生几百瓦的几乎完美的,可聚焦的纤维激光光线。

Based on these results and inferred to related reports from other labratories, it was possible to make some analyses and conclusions or inferrences:(1) CD〓AK with tumoricidal activity were induced and expanded in number througth costimulation of PBMC with anti-CD〓 McAb . and r IL-2 ;(2) CD〓AK induced and expanded in such manner did exibit more potent proliferation·ability and cytotoxicity which maintained for lonser time than those of LAK cells, thus CD〓AK was a new variety of antitumor effector cells worth to be explored;(3) CD〓AK could mediate MHC nonrestricted cytotoxicity and kill tumor target cells through inducing necrosis and apoptosis;(4) Normal mature lymphocytes of PBMC could be induced to proliferate and /or to die from apoptosis when they were costimulated by anti-CD〓McAb and rIL-2. Both proliferation and apoptosis were existing in the same cultivation system sugsesting that the presence of rIL- 2 might provide some accessary signals for apoptosis.

以这些结果为基础并参考其它有关文献可能做出如下分析与结论或推论:(1)用抗CD〓单抗和rIL-2共刺激外周血单个核细胞能诱生扩增出具有杀瘤活性的CD〓AK细胞,(2)与LAK相比,用这种方法诱生扩增的CD〓AK增殖能力强、细胞毒活性强而且维持时间长;CD〓AK是一类值得开发的抗瘤效应细胞;(3)CD〓AK能够介导MHC非限制性细胞毒活性,可以通过诱导靶细胞坏死和/或凋亡杀伤肿瘤细胞;(4)正常外周血单个核细胞中的成熟淋巴细胞在受到抗CD〓单抗和rIL-2共同刺激后既可诱导增殖也可诱导凋亡,两者并存于同一体系,推测rIL-2的存在可能为细胞凋亡提供一些辅助信号。
