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。

Mushroom bodies and antennal lobes in Oxycetonia jucunda were conspicuous. Calyces and lobes of the mushroom bodies.were much developed. In contrast, calyces of Ambrostoma quadriimpressum and Henosepilachna vigintioctomaculata were extremely undeveloped. However, the postretinal fibres and circumpharyngeal nerves of Ambrostoma quadriimpressum were highly developed. In the three beetles, 5-HT immunoreactivity was present in all neuropils of the brain and the suboesophageal ganglion. The pattern of 5-HT immunoreactivity and the localization of immunoreactive somata which often clustered into groups were similar among these beetles, while the immunoreactivity intensity was distinct, especially in the lamina.
结果显示,分类地位相近的三种甲虫脑结构大小相差悬殊:小青花金龟脑结构相对发达,蕈形体结构显著,具有发达的冠和叶,嗅叶发达;马铃薯瓢虫和榆紫叶甲的冠极度退化,嗅叶相对不发达;但榆紫叶甲具有十分发达的网膜后纤维和围咽神经。5-HT阳性纤维在三种甲虫的所有神经纤维网中几乎都有分布,且反应模式相似,但各神经纤维网特别是神经节层染色强度差异显著。5-HT阳性胞体有成群分布现象,且在三种甲虫脑中的空间分布位置基本一致。

During early middle Jurassic period, Quemocuo formation in NQB was offshore lake deposition with marine feature, in SQB was shelf deposition, which indicted that an intense rifting and sea level rising with more large range, and consequently, eroding area was shrunk and deposition area was expanded.4. According to the result of stratigraphic surface features, division and correlation, and the paleographic characteristic, Qiangtang Basin during late Triassic -early middle Jurassic period could be divided into two basin developing stages with difficult tectonic nature, remnent epicontinental basin stage in Carian -early Norian of late Triassic and rifting basin stage in middle Norian of late Triassic - early middle Jurassic period respectively.

Mallory trichrism staining exhibited light blue samples. Eight weeks following repair, CT showed round blunt defect edges in the coronal position, which had bony pustute connection with gel materials. Density at the defect region significantly increased. 3D reconstruction suggested that defects became small. After hematoxylin-eosin staining, abundant fibrous connective tissue appeared in defect regions, with bony tissues. Mallory trichrism staining revealed that maroon mature bone tissues were found, surrounded by light blue chondroid tissues. Twelve weeks following repair, coronal defect regions were filled with callus. 3D reconstruction showed that defects were repaired. Defect region and surrounding bony tissues had bony connection, with thick bone trabecula and mature Haversian system.
