減壓室-
On the basis of test results, the effects of operation parameters such as material thickness, heating temperature and pressure of drying chamber on vacuum freeze drying are discussed. aiming at decreasing drying time and reducing energy consumption, these parameters are optimized and optimization results agree well with actual results
在三因素二次正交回歸試驗的結果分析的基礎上，利用降維分析方法探討了凍干厚度、加熱板溫度和系統的真空度對乾燥時間和乾燥能耗的影響，並對混合加熱條件下單位水分能耗和凍干生產率進行了優化分析。 -
Secondly, the cfd method is used to study the flowfields in the laser chamber and the loss of the total pressure in several types of nozzles. the answer shows that reducing the length of the nozzles and the high of the throats in the nozzles can reducing the loss of the total pressure. and the answer also shows that the small nozzles with helium injected in the base region are good for laser chamber pressure recovery
其次，本文利用cfd技術模擬了光腔流場，研究了幾種噴管的總壓損失特性。研究結果表明，對于平面對稱噴管，減小噴管長度，增加喉道高度有利於減少總壓的損失。用cfd技術對光腔段的模擬表明，採用小尺寸噴管，並且在基區大量注入氦氣有利於激光器壓力恢復。 -
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。
