  1. Established hydraulic database for water supply networks incorporated all the network related manipulations including the hydraulic calculation, operation monitoring, dispatching, performance, optimum design and drawing and plotting to a full integrality

    給水管網水力計算模型數據庫的建立，可以把給水管網計算、監控、調度、運行、優化設計和繪圖有機地結合在一起。
  2. The performance characteristics of hydraulic structures are affected by many external factors. the estimate of their real operating states require the evaluation of many parameters such as the elastic modulus, the damping ratio, the friction coefficient, etc, which are extremely difficult to determine with traditional calculation methods or model test. a solution to overcome the difficulty could to be the combination of mathematical model and inverse finite element analysis based on the observed data

    由於水工建築物具有體積大，外界作用因素復雜等特點，採用常規的理論分析和模型試驗方法對其進行計算復核以及安全評價時，往往由於未知因素過多，導致研究結果精度和可信度不理想，因此，利用原型監測資料建立正、反分析模型，以掌握其實際運行狀態和變化規律的方法已在水利工程等諸多領域得到深入發展和廣泛應用。
  3. Based on calculation example, mathematic models are developed to analyze the stability and regulation performance of the unit under the conditions of small water level fluctuation and hydraulic disturbance

    結合雙機共尾水調壓室系統的實際算例，建立相應的數學模型，進行小波動和水力干擾情況下的穩定性和調節品質分析。
  4. Some of the relationship between the performance and some factors of the hydraulic damping system was found out according to the calculation and analysis

    然後針對50000kn汽車大樑液壓機的緩沖系統，分別從靜態和動態兩個方面進行了分析計算。
  5. That is, through analysis of the principle on flow control and " hydraulic transistor ", design and calculation of flow control characteristic as well as main parts in valve inner chamber, a piloted reducing valve will be installed between main valve and pilot valve. after a pressure - difference compensating reducing valve was added in the non - pressure compensating piloted reducing valve of the flow control valve in vlalvistor valve, the calculation on control characteristic emulation and load characteristic emulation has been carried out. the result of the calculation shows that after pressure compensating reducing valve was added, the linearity of the control characteristics has been greatly improved thus eliminating influence upon outlet flow by load pressure - change of the hydraulic system and improving performance characteristics of the hydraulic component

    文章還在對瑞典valvistor閥的插裝比例閥研究的基礎上，提出了一種新的流量控制原理，即：通過對流量控制和「液壓晶體管」原理的分析、流量控制特性及閥內腔主要結構件的設計計算，在主閥和導閥之間增設先導減壓閥，並進一步對valvistor閥的流量控制閥之無壓力補償先導減壓閥、加入壓差補償減壓閥后的控制特性進行了模擬計算和負載特性模擬計算，結果表明：增設壓力補償先導增壓閥后，其控制特性曲線變得非常線性，從而消除了液壓系統負載壓力變化對主閥輸出流量的影響。
