养鱼的

Can say, face the boundless ocean of electronic business affairs, do not know well the concerned branch of ability in swimming does not undertake administrative pilot, impossibly feasible detailed rules comes on stage, and collect fees of type, right by " try " the area is very not fair pilot be destined to be not pushed again -- accordingly best method is imitated property tax pilot execute free " idling ", conscientiously is placed " pisciculture " and rather than " fish ", not perfect, service is less than regulation an attitude that does not collect fees.

可以说，面对电子商务的汪洋大海，不谙水性的有关部门不进行治理试点，就不可能有可行的细则出台，而收费式的、对被"试"地区不甚公平的试点又注定推不开——因此最好的法子是仿效物业税试点实行免费"空转"，老老实实摆出"养鱼"而非"打鱼"、规则不完善、服务不到位就不收费的姿态。

Tray soilless culture evolved by the nutrient flow technology in which there was only a layer of nutrient liquid and the oxygen was very enough was designed to improve the effect of wastewater purified by the terraneous It was showed that when the height of the tray was 1cm, and six layers of clothes were laid on the tank to filtrate and hold wetness the wastewater, furthermore, the gradient of the tank was between 2 and 8, the tray soilless culture was the most feasible.

为了提高陆生植物净化废水效果，根据仅有一层营养液流过栽培容器的底部而使供氧条件大大改善的营养液膜技术衍变而设计一种栽培方式即育苗盘种植。试验研究表明，最适的盘培方式为育苗盘高度为1cm，栽培槽上再铺设6层无纺布用于养鱼废水的过滤、保湿，另外，栽培槽的坡度设计在2％—8％之间。

The test results showed that when the cycle water flow was 65m^3/h and the oxygen flow was 1, 2,……, 10L/min, the relationship between the dissolved oxygen and oxygen flow in the water was y=0.1009χ^2+0.0594χ+5.9588 (r=0.9927). According to the mass balance principle, the maximum oxygen utilization rate of oxygen cone was calculated at 84.56%. Under the condition of the maximum oxygen utilization rate of oxygen cone, according to the rate of Nile tilapia oxygen consumption, the number of oxygen cone was projected in industrialized fish farming system. It provided the basis for oxygen supply system design in industrialized fish farming system.

结果表明，在循环水流量为65 立方公尺/h，水温24.5℃，氧气流量为0， 1， 2，……，10 L/min的条件下，溶氧与氧气流量回归方程为y=0.1009χ^2+0.059 4χ+5.958 8(r=0.9927)；根据物料平衡原理，推算出氧气锥的最大氧气利用率为84.56%；在最大氧气利用率的条件下，依照尼罗罗非鱼的耗氧率计算模式，推算出工厂化养鱼系统需配置氧气锥的台数。

Grass planted in symbiosis ecosystem of fish and grass could absorb the nutrition of the waste water which supplied a feasible condition of normal growth, and was the food of the fish, so it was an important meaning.

在鱼草共生系统中，种植的牧草可以吸收循环养殖系统水中的营养物，为鱼的正常生长提供一个适宜的环境，同时生产的饲草可以养鱼，因而具有重要意义。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
