Phenylalanine agar is recommended for the detection of production of phenylpyruvic acid from phenylalanine by deamination. A positive reaction results in a green coloration after the application of 10% ferric chloride.

苯丙胺酸培养基可用来测定苯丙胺酸经去胺反应所产生的苯丙酮酸，在滴加10%氯化铁溶液后，如呈现绿色，即表示有反应。

The results show that it is impossible to carry out fire suppression by flame cooling and surface cooling for smaller droplet. The extinguishing mechanism for them depends primarily upon decalescence via gasification.

结果表明：对于滴径较小的雾滴不可能达到火焰区或可燃物表面实施火焰冷却和表面冷却，其灭火作用主要依赖于汽化吸热。

Impossible for my mother. It was nice to be alone, not to have to smile and look pleased; a relief to stare dejectedly out the window at the

一个人呆着真好，不必面露微笑让自己看起来很愉快；沮丧地凝视着窗外如注的大雨，掉几滴眼泪是一种解脱。

It was nice to be alone, not to have to smile and look pleased; a relief to stare dejectedly out the window at the sheeting rain and let just a few tears escape.

一个人袋着真好，不必面露微笑让自己看起来很愉快；沮丧地凝视着窗外如注的大雨，掉几滴眼泪是一种解脱。

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。
