| 1. | Pumping sediment - laden flow at the suitable places in the irrigation canal system is a new way to deal with siltation 泥沙长距离输送,使绝大部分泥沙进入田间,就可实现引黄灌溉的良性循环。 |
| 2. | In many low head hydraulic structure , expecially canal system structure , we are used a dopting underflow energy dissipation 在众多的低水头水工建筑物中,特别是渠系建筑物中的涵闸下游,多采用底流消能。 |
| 3. | Arch net floor has opened up a new way for the small - sized works , expecially for the canal system structures of low frouda number underflow energy dissipation 拱网为小型工程特别是渠系建筑物低佛氏数底流消能开辟了一条新途径。 |
| 4. | According to the results , the author put forth the theory of canal system of the meniscus , and consequently the theory of synovial fluid propulsion system , through which the menisci gained the nutrition 因此,据此实验结果提出“半月板管道系统”理论,进而提出半月板营养获得的“滑液推动系统”理论。 |
| 5. | Layout forms of irrigation canal system can be generally classified as three categories : series - wound canal system , equivalent shunt - wound canal system and nonequivalent shunt - wound canal system 灌溉渠系的布置形式一般可分为串联渠系、等效并联渠系和非等效并联渠系,对这3种灌溉渠系水利用系数进行了理论研究。 |
| 6. | The results of correlation comprehensive array analysis indicated that the water seepage from canal systems was the main cause resulting in the uprising of underground water table and the increase of soil salinity in qyrid 同时通过关联度综合排序分析,确定出渠系渗漏是造成灌区地下水位高、土壤盐渍化的主要原因。 |
