纤维束

The corium is under the epidermis, it's made up of connective tissue that contains collagenous fiber, elastic fiber, reticular fiber and ground substance between fasciculus, it's very important for the elasticity and lusty of the skin, malnutrition, ageing and long-time excessive exposure to the sun would all lead to wrinkles and sagging of the skin, the reason of this is denature or fracture of collagenous fiber and elastic fiber.

真皮在表皮之下，由胶原纤维、弹力纤维和网状纤维组成的结缔组织，与纤维束间的无定形基质构成，对皮肤的弹性光泽和弹力等有着重要作用，营养不良、衰老或长期过度日晒会使皮肤发生皱纹、弹性松弛，是胶原纤维及弹力纤维变性或断裂的结果。

The results showed the radioscaphocapitate,radiolunate,ulnolunate,ulnotriquetral and dorsal radioulnotriquetral ligaments were composed of densely fasciculated collagen fibers which contained more elastic fiber.

结果显示，桡舟头韧带、桡月韧带、尺月韧带、尺三角韧带和腕背侧桡尺三角韧带中均可见致密粗大的胶原纤维束，束内含有大量的弹力纤维；桡舟月韧带中缺乏弹力纤维，但含有丰富的血管；腕尺侧副韧带中无明显的胶原纤维和弹力纤维可见。

The microstructure of MDF and MDF tested were studied. The results showed that the fibers in MDF are arranged randomly. Some of them arranged separately, most of them arranged in bundles. There are many blind holes between the fiber cells in MDF. The damage of MDF's compressive creep is the result of new cranny occuring, spreading and the combination of old cranny. In the repressing process, besides the pressure, heat is also the main factor on the damage of MDF, which can accelerate the adhension layer to deteriorate and lead to the gule strength decreasing.

结果表明：MDF的纤维排列无规则，纤维排列形态除少量纤维呈单根状外，大量的纤维以纤维束的形态排列；纤维之间存在许多大小不等的孔洞，呈不贯通状；MDF蠕变损伤是不断萌生新的裂隙并扩展和合并原有裂隙的结果；MDF二次加工过程中，除了压力是破坏MDF结构的主要因素外，加热温度使MDF胶层老化，胶合强度下降，也是破坏MDF结构的主要因素；MDF的破坏形态除了有纤维拉断外，还有纤维拔出和胶粘剂脱落。

Fractional anisotropy were measured in the genu, body and splenium of corpus callosum, horizontal part and posterior part of the bilateral cingulste fibers.

目的 探讨创伤后应激障碍患者是否存在连合纤维束胼胝体及联络纤维扣带纤维束的超微结构异常。

They were composed of wavy and tendinous collagen fiber fascicles, among which a small amount of loose tissue was found to be intermingled with vessels.

桡舟韧带、桡舟头韧带和桡月韧带的组织结构相似，由肌腱样的胶原纤维束组成，胶原纤维束之间有少量的疏松组织，其间有血管分布，胶原纤维束呈小的波浪状。

From the point of view of structure,bamboo cell wall ratio,amount of bundle per unit area,fraction of bundle sheath,fraction of vessel increase from the root to the top of the bamboo,while fractionof parenchyma.Single bundle sheath area decreases with the increase of height.Fiber length,fiber width and vessel length increase from the root to the top andget theirs maximum value at the length of 17th node to 23rd node and thendecrease.Fiber length and width ratio slightly decreases while vessel widthincreases with the increase of height.

从构造角度来说，竹材胞壁率、单位面积维管束个数、纤维束比量、输导组织比量从基部到到梢部随着高度增加而增加，而薄壁组织比量、单个维管束纤维束面积随着高度增加而减小；纤维长度、纤维宽度、导管长度从基部到梢部随着高度的增加而增加，在第17竹节到第23竹节达到最大值，而后下降，纤维长宽比随着高度的增加而缓慢下降，导管宽度随着高度增加而一直增加。

On the ground of comprehending the mechanism of fiber filtering and the characteristic of other fiber-filters,the characteristic and the function of long-fiber filtering was studied by the comparison between long-fiber filtering and sand filtering in this article.

在深入了解纤维束过滤机理和总结现有各种纤维束过滤器优缺点的基础上，通过长纤维过滤与传统石英砂过滤的对比试验，详细论述了长纤维过滤较之石英砂过滤的技术特点与性能优势。

Results Fascicles and certain amount (207) of motor fibers from the anterior division of C7 were distributed to musculocutaneous nerve and median nerve, the orientation of these fibers were not clear. The ones (323) from posterior division were to the axillary, radial, and dorsal thoracic nerves, thus the orientation of these fascicles was relatively definite.

结果 大鼠C7神经根前股发出一定数量的运动纤维到肌皮神经、正中神经，总量约207根，但在C7前股定位不明确；后股发出相应的运动纤维束支到桡神经、腋神经与胸背神经，总量约323根，这些束支在C7后股的定位较明确。C7神经根所支配的范围很广，其中以C7后股发出的胸背神经束支支配的背阔肌占比例最大（运动纤维含量＞50%）。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
