Bamboo variation ofmicrodensity of all age-degree and all height bamboo from bamboo green tobamboo yellow as follows:The downtrend ladder of microdensity the firststage from bamboo green to bamboo yellow is relatively large,normally at theplace 0.35 from bamboo hull(the thickness of from bamboo hull to bambooyellow is 1)micro-density downtrend ladder begin to get smaller,variancerange of microdensity is smaller.When reaching near bamboo yellow area,microdensity reaches its minimum value,and when reaching bamboo yellowsection density increase rapidly,the minimum density of bamboo is only 50% orless of maximum density.Bamboo yellow is comprised of stone cells whichhave thick cell wall,so its density is high,normally 50% to 100% more thanminimum density.Bamboo yellow′s lay thickness is thin,normally the samethickness for all age-degree and all height bamboo,about 0.8mm.From 1 age-degree bamboo to 2 age-degree bamboo during growth,the increase of averagedensity is mainly in bamboo pulp section,from 3 age-degree bamboo to 4 age-degree bamboo,the decrease of average density is mainly decrease in the pulpsection.Same age,same height,the less the density ladder of bamboo radialthickness,the higher the mechanical strength.
所有年龄所有高度的竹材微密度从竹青到竹黄对材性变异规律如下:从竹青到竹黄开始下降梯度较大,一般到相对竹皮距离0.35左右处(整个竹壁厚度为1),竹材微密度下降梯度减小,微密度的变化范围变小,到近竹黄处,微密度达最小值,而后到竹黄部位密度大幅上升,竹材最小密度一般只有最大密度的50%或更低,竹黄由厚壁的石细胞组成,所以密度较大,一般比最小密度增大约50%-100%,厚度较薄,不同年龄不同高度竹材的竹黄厚度相差无几,约在0.8mm左右;竹材从1度竹到2度竹生长过程中,平均密度的增长主要发生在竹肉部分,从3度竹到4度竹生长过程中,平均密度的下降主要发生在竹肉部分,同一年龄同一高度,竹壁厚径向的密度梯度越小,力学强度越高,随着年龄的增大,密度梯度越来越小(1度竹除外),随着高度增加,密度梯度越来越大。

With the system, in vivo experiments were performed and the result proved the validity and feasibility of this approach. The result can be presented like this: the mean WSR value of common carotid artery from healthy adults is between 150~350s-1, and the max WSR value is between 450~750s-1; with comparing the WSR value from a male who is suffering from the internal carotid artery straitness with the natural range of WSR, a phenomenon was found that his max and mean WSR value are both smaller than the natural value evidently.
并且利用该系统进行了大量的在体实验研究,得到了相应的结果并验证了该方法的有效性及可行性,该结果显示:健康成年人的颈总动脉的血管壁剪切率平均值范围为150~350s-1,最大值范围为450~750 s-1;将患有颈内动脉狭窄的患者的血管壁剪切率与正常范围比较发现,其血管壁剪切率的最大值及平均值均显著小于正常范围。

Based on the above study, a program is developed which calculate the modeled subgrid stresses, and is applied to simulate the turbulent flow in a plane channel. The computational result is compared with the data extracted form a DNS database, and the agreement is satisfactory. A numbers of physical phenomenon has been reproduced in the simulation, including hairpin vortex and counter-rotating rolls in near wall region, intermittent vortex structure, the maximum of pressure clustering in wall area and the high-speed fluid sweep into the low speed fluid, and the ability of the LES to simulate turbulent flow is well shown.

The thickness of the ice cover on the wall surface heat transfer is greater than the thickness of it on the air heat transfer form. The thickness of the ice cover on the wall surface heat transfer along the way changes slowly, but it on the air heat transfer along the way changes significantly. Reducing the entrance velocity, lowering the wall surface or air temperature, the formation of the thickness of the ice cover will increase; in the 3D circumstances, The thickness of the ice cover was relatively uniform in the import of the U-turn model, the ice cover was gradual accumulation in the convex bank when the stream traversed the import of the U-turn model, the thickness of the ice cover in the convex bank was significantly bigger than the thickness in the concave bank. The temperature field under the ice cover tends to be complex because of the existence of the secondary flows. The temperature in the convex bank is greater than it in the concave bank. Compared with the data from experiments, the laws in the numerical simulation are similar with them in the experiments
模拟结果显示:二维情况下,运用壁面传热形成的冰盖厚度大于运用空气传热形成的冰盖厚度,壁面传热形成的冰盖厚度沿程变化缓慢,而空气传热形成的冰盖厚度沿程变化明显,减小入口流速,降低壁面或空气温度等,形成冰盖的厚度都会增大;三维情况下,弯道入口处凸、凹岸形成的冰盖厚度基本相同,进入弯道后,凸岸形成的冰盖厚度逐渐增大,而凹岸的冰盖厚度逐渐减小,受横向环流的影响,冰盖下水流的温度场趋向复杂,并且凸岸的温度小于凹岸的温度;与实验室实验所得数据相比较,数值模拟研究得到的规律基本符合实验规律。
