中脉

The results of character evolution history reconstruction shows the SC in PT and AD clade might be a homoplasy character; also, the SC in PT clade might have multiple origins. SC in Pteridaceae has some special characteristics:(1) the cell long axes usually run parallel to the lateral veins;(2) Most of Pteris and Adianum species have VSC only in lower epidermis;(3) Species have ISC also have VSC.(4) Presence of spicular cells is highly correlated with the long veinal epidermal cells. Species have type III silica deposition type usually have longer and narrower veinal epidermal cell compared with ordinary epidermal cells; Species have type IV silica deposition type also have long epidermal cells, but not significantly different from ordinary epidermal cells.

本实验中亦发现凤尾蕨科之矽异形细胞具有几项特色：(1)矽异形细胞之长轴多与叶片侧脉方向平行(2)发现多数铁线蕨属以及凤尾蕨属植物仅下表皮具有脉上矽异形细胞；(3)具有脉间矽异形细胞的种类会同时具有脉上矽异形细胞；(4)长条形的侧脉上表皮细胞与矽异形细胞具有相关性，仅具脉上矽异形细胞的分类群之脉上表皮细胞均较一般表皮细胞细长；具有脉间矽异形细胞之物种之脉上表皮细胞亦为长条形但形态与一般表皮细胞常无明显形态差异。

Observations on the dichotomous leaf venation of Circaeaster agrestis found no intermediate forms of the fusion of vascular bundles between the two completely fused commis-sural veins of anastomoses and the two separate approximate veins, but found different degrees of the vestige of commissural veins .

在星叶草叶二叉分枝脉序中，网结脉中2条完全汇合叶脉与靠近脉中完全分离叶脉间未发现任何形式的维管束汇合的中间类型，相反观察到了网结脉中不同程度的连接脉退化的痕迹，因此网结脉不可能由靠近脉形成；盲脉的出现与齿的退化、网结脉中连接脉的间断及非网结脉由分枝处间断等相关；上述事实表明星叶草叶的二叉分枝脉序应为一减化性状。

Results Cuticular papillates,glandular hairs,peltate scales,and non-glandular hairs presented on the leaf epidermis of C.paliurus.Anomocytic stomata were confined to the lower epidermis.Large cluster crystals existed in the uppermost layer of palisade cells.Midrib included one closed vascular system and one additional vascular strand.Secondary veins are semicraspedodromous and form marginal loops,tertiary veins are percurrent,quaternary veins form orthogonal or polygonal areoles filled up by branched and freely ended veinlets.

结果青钱柳叶表皮有许多小乳突，腺毛，盾状鳞片和非腺毛表皮毛；气孔器不规则型，仅分布于下表面；靠近表皮的叶肉组织中有规律地分布含簇晶的细胞；主脉中维管组织环状，封闭，具有一个副维管束；二级脉在叶缘内分支，相互连接形成脉环，三级脉及顶型，脉间区内充满分支的自由结束的小细脉。

The aim of all yogic and other spiritual practics is to release the great cosmic power or kundalini shakti which lies coiled three and a half times in mooladhara chakra .the process of awakening this force,or prana ,is described in the scriptures as ,"the flight of a bird sising from earth to heaven ,tied to a golden thread ".the earth is mooladhara chakra ,heaven is ajna chakra ,the bird is mahaprana and the golden thread is sushumna nadi which runs through the centre of the spinal column,by manipulating ,storing and expanding the prana within the body it is possible to awaken the sleeping prana shakti .this is the fundamental purpose of the yogic sciences of pranayoma (expanding the dimensions of prana )and prana vidya knowledge of prana

所有瑜伽修行者和其它精神上的习练者的目标是唤醒被牢牢束缚纯真轮的在力量。这个过程就是启动巨大的宇宙力量或者是灵性的能量，这个过程被描绘成这样的一幅图画：金色的鸟从地球飞向天空，但由于重力却飞不上天空，被一根金线牢牢的束缚。那么这里，地球就是纯真轮，天空就是眉心轮，飞鸟就是巨大的能量，那金色的线就是中脉，是贯穿脊柱的通道。通过操纵、储藏和扩充身体内的能量从而有可能唤醒休眠的能量。这是瑜伽呼吸科学和瑜伽能量知识的基础。

Periodic fluid pulsation in aeroplane hydraulic piping could induce fluid-construction vibration and lead to fatigue damage. It is impossible to find the error sensor's optimization location because of the pressure standing wave, and the pulsation attenuation effect is not perfect when adopting pulsation attenuation at single point. For this reason, a distributed active control method of fluid pulsation was presented. To avoid stationary point in all aviation states, several fluid pulsation actuators and error pressure sensors were placed along the piping. The second fluid pulsation produced by actuators can counteract the primary pulsation brought by aviation piston pump and make the mean pulsation of whole piping minimum when adopting adaptive feed- forward control and the filtered-X least mean square algorithm.

针对飞机液压能源管路系统中的周期性流体脉动诱发流固耦合振动，导致管路疲劳损伤的问题，针对管路中存在压力驻波特性，在采用单点消振时寻找误差传感器最佳布局位置困难而引起脉动抑制效果不理想的缺点，提出了一种分布式流体脉动主动控制方法，即沿管路不同位置布置多个主动消振阀和误差压力传感器，在任意飞行阶段，避开压力驻波点，以误差压力传感器的脉动测量值为控制目标，采用一种针对周期脉动主动控制的自适应前馈控制法和多通道自适应滤波－X LMS算法，调整控制器参数，使主动消振器产生的次级脉动与管路中的初始脉动相互抵消，达到整个管路中的平均流体脉动最小的效果。
