This paper studies the main geometrical parameter such as angle, height, width, stagger and the upper width in dentation and trapezoid flow path, firstly, uses the single-phase numerical simulation of the computational fluid dynamics technique to analyse the influence of different geometrical parameter on discharge coefficient and flow state exponent of drip emitter. Secondly, uses the two-phases numerical simulation of CFD (1% sand content ) to analyse the influence of the above mentioned geometrical parameter on the contribution regulation of sand and anti-clogging performance. Thirdly, uses the PIV （ particle Tracking Velocimetry ） technique which can see the small-scale flow path to observe and test the trajectories and velocities of solid particles in labyrinth flow path, and analyses the basic factors which can influence the movement characteristic of solid particles and the flow state in flow path.

本文以齿形流道、梯形流道为主要研究对象，以流道转角、流道高，流道宽、偏差量及梯形流道上底宽为主要结构参数，首先应用 CFD 单相流数值模拟技术对不同结构参数灌水器流道水力性能进行模拟，分析了不同结构参数对流态指数和流量系数的影响，其次，应用 CFD 两相流（含沙量为1%）数值模拟技术分析了结构参数对含沙量分布规律和抗堵塞性能的影响，然后，应用 PIV 可视化测试方法测试了固体颗粒在流道内运行轨迹及速度，分析了影响固体颗粒运动特性及流道内流体流态的基本因素，最后，对上述流道结构形式通过模具加工及滴灌带试制，进行了标准化测试（ GB/T 17187-1997 农业灌溉设备滴头技术规范和试验方法与 ISO 标准 ISO /TC23 /SC18 /WG5N4短周期堵塞测试程序），测试结果验证了 CFD 模拟结果，并提出了迷宫结构流道灌水器的抗堵塞设计方法。

Cd〓 (1, 10, 100, 1000μM) stimulated directly GtH secretion from pituitary of common carp in vitro, with the highest GtH secretion at 100μM, GtH secretion stimulated with 1000μM Cd〓 was not higher than that stimulated with 100μM Cd〓.The antagonism between Ca〓 and Cd〓 in perfusion of the pituitary fragments was not obvious.After being preperfusion with 100μM Cd〓(with or without Ca〓), the GtH secretion of the pituitary fragment was irresponsive to 2-min pulse stmulation of 10μM sGnRH-A.

鲤鱼脑垂体碎片离体灌流孵育实验结果显示，Cd〓（1，10，100，1000μM）可直接刺激鲤鱼脑垂体分泌GtH，灌流液中Ca〓对Cd〓的拮抗作用不明显，100μM Cd〓刺激脑垂体分泌GtH达到高峰，Cd〓浓度增加到1000μM时，脑垂体分泌GtH并没有进一步增加，甚至有减少的趋势；100μM Cd〓预灌流脑垂体后，可使脑垂体对2-min 10μM sGnRH-A刺激的反应性消失；1.25mM的EDTA可消除100μM Cd〓刺激脑垂体分泌GtH的作用；TFP和Cd〓同时灌流脑垂体一段时间后，撤除TFP可使脑垂体分泌GtH显著增加，即出现"反跳"现象。

At the same time,the protective effect of mannital and VitC were assessed.Result:The serum level of creative phosphokinase and malon dialdehyde was higher,but superoxide dismutase activity was lower during reperfusion than in the ischemic period.The tissue structure and ultrastructure were damaged more seriously in reperfution period. After treated by mannital and VitC, the level of CPK and MDA in serum was lower, but SOD activity rasied, and the ultrastructure was better.

To resolve this behavior, only the surface business card printing and membership card making to set to print in ink that is not on the surface without worrying about the colour, there are three ways: the first one is a drumlike complex members'meeting, Bopp/business card printing and membership card making/PE, such a structure you need to have special line cost more per bag fee in order to achieve $ 0.10/only, the second film structure is the PE/business card printing and membership card making/PE, such a structure common packaging equipment can also be filling, but cost more, each bag shall be $/only 0.08, the third option is the-tape-PE/business card printing and membership card making/PE structure in the original film, that is, the members'meeting membrane business card printing and membership card upon completion of the making of the operation, the business card printing and membership card making surface salivate a layer of transparent with thin-film, this is our company according to actual usage of the product structure specially developed.
