DMBQ, ferulic acid and resorcin were effective chemical signal substances in the process of seed germination and haustorium formation of Cistanche deserticola. 4.The embryo is consist of 12 cells, the endosperm cell degraded so as to provide nutrition for the embryo development .As a result, germ tube differentiated from the embryo and came out through micropylar end, the small cell at the tip of the germ tube held the capacity of cleavage and the other cells grew big ,so the germ tube elongated .The anterior extremity of germ tube swelled to form haustorium under chemical substances treatment, the haustorium cell stained ,especially its portrait because of the lignification of the cells.
肉苁蓉种子的胚是由12个细胞紧密排列形成的圆球状胚,球形原胚分裂增殖的同时,胚乳细胞分解,为胚细胞的增殖提供营养,最终胚上分化出的芽管由珠孔端冒出,芽管前端细胞较小,具有旺盛的分裂能力,后部细胞体积增大,芽管逐渐伸长,在化学物质的诱导下,芽管由中部至前端细胞膨大分化出初生吸器,初生吸器呈帽子状,而这些细胞比其周围的细胞着色深,吸器纵向局部区域的番红染色加深,细胞高度木质化。

In this thesis, I summarize the theoretical calculation method, applied scope and notice of siphonic drainage system, and point out the advantage of siphonic drainage system compared with gravitation drainage system. In the archetype experiment study of siphonic drainage tube, I adopt different tube diameter and different structural height to survey the drainage volume and press in different place. I observe various kinds of flow state, and get chief factors which influence hydraulic peculiarity of system as the tube diameter or structural height, and find out the relevance of factor to flux. I apply CFD Fluent software and adopt standard k-ε model and RNG k-ε model, then use finite volume method and second-order upwind scheme to discrete numerical model, while coupling numeration of velocity field and press is based on SIMPLE. In the numerical simulation of curved part of tube, siphonic drainage tube experiment system and multi-outlet siphonic drainage system, I make research on internal velocity and press of system in different project condition by changing the tube diameter of curved part, negative press value in tube export and improving the quantity of water gutter. This thesis first adopts a method of combining archetype experiment and numerical simulation to study the siphonic drainage system, test and verify the validity of experiment and numerical simulation, and makefurther study on system, it solves the problems of limited testing conditions, and has a logical results, it can provide a valid method for optimizing and designing the drainage tube-net system. The conclusion have referring value for study and design of siphonic drainage system.
本文首先对虹吸式排水系统理论计算方法、适用范围以及注意事项做出总结,并分析了虹吸式排水系统的优势;再对虹吸式排水管道进行原型试验研究,采用不同管径不同立管高度,对系统流量、管道压强进行量测,观察了各种工况下的流态,对其水力特性进行研究分析,找出影响水力特性的落差、管径主要因素以及与排水量的关系;进一步应用计算流体力学Fluent软件,采用标准κ-ε模型与RNGκ-ε模型,计算过程应用有限体积法和二阶迎风格式对数值模型进行离散,速度和压力的耦合采用SIMPLE算法,分别对系统弯管段、虹吸排水管道试验系统、多斗虹吸式排水系统进行数值模拟分析,通过改变管段弯头处半径、管段出口负压值、增加雨水斗数对不同工况下系统内部的速度和压力进行研究;本文首次采用结合原型试验与数值模拟相结合的方法,对虹吸式屋面雨水排水系统进行研究,试验与模拟相互验证,并进行拓展,很好地解决了虹吸式屋面雨水排水系统由于试验条件限制问题,结果正确合理,为排水管网系统设计和优化研究提供了有效的方法,对工程设计有较好的参考价值。

One, suck phlegmy the preparation before works 1 should make sure negative pressure attracts plant above all each conduit joins correct, close together, unobstructed, assure significant negative pressure, general adult 10.64~15.96Kpa, the baby should be controlled in 7.98~10.64Kpa. 2 preparation rinse the asepsis physiological saline that smokes phlegmy pipe 2 bottles, 1 bottle wash pump technically with Yu Chong the suction inside tracheal spile is phlegmy canal , additional 1 bottle rinse those who had sucked mouth, nasal cavity technically to smoke phlegmy pipe . 3 equipment are very different the asepsis of model sucks phlegmy canal and asepsis glove. 4 because suck phlegmy itself,be a kind of stimulation to the patient, sober patient is not willing to suck normally phlegmy, and the family member of insensible patient also thinks to suck phlegmy special anguish.
一、吸痰前的预备工作1首先要保证负压吸引装置各管道连接正确、紧密、通畅,保证有效的负压,一般成人10.64~15.96Kpa,婴儿应控制在7.98~10.64Kpa.2预备2瓶冲洗吸痰管的无菌生理盐水,1瓶专门用于冲洗抽吸气管插管内的吸痰管,另1瓶专门冲洗吸过口、鼻腔的吸痰管。3备好不同型号的无菌吸痰管及无菌手套。4由于吸痰本身对病人是一种刺激,清醒的病人通常不愿意吸痰,而昏迷病人的家属也认为吸痰非凡痛苦。

The process of sand absorption is:(1) the vibration head vibrates and losses the sand layer, and supply high pressure air into the sand absorption head;(2) the high pressure air generates negative pressure in the sand absorption pipe when it is discharged out from the sand absorption;(3) the sand absorption head and the vibration are shifted downwards and maintains the water flow straightly.
取砂土的过程为:(1)振动头振动松散砂土层,同时向吸砂头供入高压空气;(2)高压空气通过吸砂头从排砂管向上排出的过程中,在吸砂管内产生负压,吸砂管将管口处的水和砂土吸入到吸砂头内,在高压气流作用下,吸砂头内的砂、水和气混合而成的三相流通过排砂管排出到受砂船上;(3)在吸砂的过程中,适时地将吸砂头和振动头下移并保持钻孔套管中的水流畅通。
