  1. In pumping fluid with gas, pressure boost can be improved by enhancing the pump rotation speed, thereby improving the performance of the pump to a certain degree ; when the gas content is constant, by increasing the inlet pressure, the pressure boost can be enhanced and the pump efficiency be improved remarkably ; when the gas content is rather high, there will be a problem of matching between the gas pressure and the fluid pressure ; the performance of the multiphase pump can also be improved by means of rational design of buffer vessel and homogenizer

    試驗分析認為，氣液混輸工況下，提高泵轉速可以提高增壓，在一定程度上能改善多相泵的工作性能；含氣率一定時，增加進口壓力，可使多相泵增壓值增大，泵效明顯增加，最大含氣率點后移，但含氣率很高時，存在氣液壓力相匹配問題；改進緩沖罐和均化器的設計，有利於氣液互相夾帶，避免氣囊產生，可改善多相泵的輸送性能。
  2. This paper expounded the consideration on researching and developing the new technical model in hilly drainage area during the process of agro - industrial structure adjustment, its characters of energy and material recycles, with the emphasis on introducting the efficiency of three renovation techniques in hilly area of northern fuzhou, i. e. construction of artificial grassland and feeding goats in rotation, qualified forage for pisciculture use, and ecosystimatical resilience of hilly orchard and improvement of its productivity

    摘要闡述了在南方山地小流域農業產業結構調整中配套技術模式的研發思路及能量物質循環特點，重點論述山地人工草場的建設及山羊分區輪牧、優質牧草漁業產業化利用和低產山地果園生態恢復與生產力提升等三項創新性技術在福州北峰山地小流域實施的成效。
  3. This system makes a breakthrough of traditional incremental motion control theories. it breaks the strict ambit between continuum and discrete, speed and position, rotation and step, the space vectors of stator magnetic field and rotor magnetic field are selected as the main control objects, incremental motion control and motion control are combined organically to make incremental motion control develop to large capability, high efficiency, high precision

    這其中的交流步進控制理論打破了傳統的增量運動控制思想，打破了連續與離散，速度與位置，旋轉和步進的嚴格界限，以定、轉子磁場空間矢量為主要控制目標，將增量控制與運動控制有機的結合起來，使增量控制向大容量、高效率、高精度方向發展。
  4. Cross universal coupling is mainly used for rolling machine, mining machine, transportation machine, petroleum, shipping, making paper and other heavy - duty machine, is the most common and highest efficiency gearing, it has larger transmit moment, bigger angle, more flexible rotation, longer life than the old - type plum blossom shaft, smooth piece universal shaft, and gear coupling, it s a new generation product of changing the metallurgy steel rolling equipment reconstructive technology

    利用其結構的特點能使不在同一軸線或軸線折角較大或軸向移動較大的兩軸等角速連續回轉，並可靠地傳遞轉矩和運動。其最大的特點是各向位移補償能力強，結構緊湊，傳動效率高，維修保養方便。廣泛應用於冶金機械，石油機械，造紙機械，工程機械，起重運輸機械以及其他重型機械等等。
  5. Maximum efficiency is obtained by the continous reappraisal of the breading-value of each selected tree as it approaches rotation age.

    只有到樹木接近輪伐期時，對所選的每株樹木的育種值，應作反復多次的評價，才有可能獲得最大的效益。
  6. Common control methods include applying disease - resistant cultivar, crop rotation, organic fertilizing, cultivate measures and soil disinfection, combined with biological control and high - efficiency, low - toxin chemical fungicide

    在防治上可綜合運用抗病品種、輪作倒茬、增施有機肥、栽培防病、土壤消毒等農業措施，結合生物防治或高效低毒殺菌劑進行綜合調控。
