高定额的

Results show 1 the total water requirement of the crops in the Jinghe Watershed is 740543.20×10^4 m^3, accounting for 41.58% of the total water requirement of the region; 2 of the two major groups of crops, grain crops are higher than cash crops in water requirement quotas; and among specific crops, vegetables, melons, rice and cotton are higher and sunflower, potato and benne are lower than other crops; 3 water requirement per hectare varies from county to county with the highest being 5682m^3hm^(-2), in Jingyang County, and the lowest 4022 m^3hm^(-2) in Dingbian County, averaged to 4 583 m^3hm^(-2), but the water requirement quota of a crop does not vary with the county, so calculation of water requirement quota of a county is closely related to its cropping structure; and 4 because of serious waste of water in farming, the actual water consumption in agriculture in the region is much higher than the calculated crop water requirement.

结果表明，泾河流域农作物需水量总计740543.20万立方公尺，农作物需水占总需水量的比例较高，为41.58%。粮食作物需水定额较经济作物高；就具体作物而言，菜、瓜类、水稻、棉花等需水定额较高，向日葵、薯类、胡麻等较低。各县单位面积需水量差异较大，平均值为4583立方公尺hm^(-2)；泾阳县最高，为5682立方公尺hm^(-2)，定边县最低，为4022立方公尺hm^(-2)。由于事先设定大多数作物的需水定额不随县的改变而改变，因此需水量与作物结构密切相关。农业用水浪费严重，使泾河流域农作物实际用水量远高于需水量的理论计算值。

And the enterprises are seriously constrained. There are also many problems in its physical distribution management. For example, its sell t physical distribution has no exactly market forecast and perfect system, and the cost of depart sell is high. As to the stock accommodate part of accommodate physical distribution, material stock is depend on experience; Information of providers is not enough more; the estimate system of providers is distemperedness.

川仪一厂的物流管理也存在要解决的问题，其销售物流市场预测不准确，体系不完善，分销成本高；供应物流采购供应部分是物资采购凭经验，供应商信息资料不多，供方评价体系不健全；而供应物流库存部分是存货、在制品资金占用较大，流转速度慢；生产物流物料定额部分是生产过程的物料消耗定额粗糙。

Experimental results showed the full bridge resonant laser power supply reaches the index of high power and efficiency; has the advantages of small volume, light weight and high precision; can make full use of the rated value of power switch and the power supply even more reliable.

实验表明，基于CPLD的全桥谐振式激光电源能够达到大功率，高效率的技术指标；具有体积小，重量轻，精度高的特点；能更充分合理的利用功率管的定额参数，使电源工作运行更加可靠。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
