藉助自行設計製作的稻田滲漏計，在杭州餘杭對高肥力稻田不同施用尿素氮肥情況下，稻田地表水和滲漏水中銨態氮、硝態氮和總氮（簡稱三氮）的動態變化規律進行了研究分析，以利於發現氮素在地表水體變化和淋失規律，盡量減少氮素淋失對地下水體所造成的影響。Objective : to investigate the effects and complications of hypertonic saline in the treatment of hyponatremia in patients with obstinate heart failure and to find out prophylactic and therapeutic measures against the complications. methods : to analyze the changes of electrolytes, urea nitrogen, serum creatinine, heart rate, blood pressure, cardiac function after the treatment of hyponatremia in patients with obstinate heart failure by 3 hypertonic saline. results : after the improvement of hyponatremia, cardiac function, the levels of electrolytes, urea nitrogen, serum creatinine were improved significantly. blood pressure rised slightly. heart rate did not change. conclusion : hypertonic saline can redress hyponatremia, improve cardiac function and decrease the levels of urea nitrogen and serum creatinine rapidly and effectively. blood pressure and heart rate did not change significantly
目的探討高滲鹽水在低鈉性頑固性心力衰竭治療過程中的作用和可能出現的並發癥以及防治對策.方法分析3高滲鹽水治療低鈉性頑固性心力衰竭前後的電解質、尿素氮、肌酐、心率、血壓、心功能的變化.結果治療前後心功能、電介質、尿素氮、肌酐有明顯改善，血壓輕度升高，心率無明顯變化.結論高滲鹽水能快速有效地糾正低鈉血癥，有助於心功能的迅速改善，降低血尿素氮、肌酐.對血壓和心率影響不大Plasma nitriding is an application way to metal surface and heating treatment based on the formed plasma by glow discharge. nitriding is a way of heating treatment, namely, metal accessory is put into activate nitrogen and the gas of low light pressure is ionized into energy electrons, high energy ions and high energy neutral atoms by the action of the electric field under a definite temperature and the time of the heat preservation
等離子滲氮是利用輝光放電形成等離子體在金屬表面，熱處理方面的應用，滲氮是強化金屬表面的一種熱處理方法，是將金屬零件置於活性氮的介質中，在一定溫度和保溫時間下，低光壓氣體在電場作用下使之電離產生能電子、高能離子和高能中性原子。However, the movement and transformation of n in soil under fertigation remains unclear. the methods of simulation experiment and culture experiment were used to study the movement and transformation of n in soil under fertigation by drip irrigation. the main experimental results were shown as folio wings : ( 1 ) the water infiltration under drop irrigation is a point infiltration ; and the soil moisture in vertical and horizontal directions was increased with the irrigation time, and the movement rate were decreased with the irrigation time
本研究採用室內模擬試驗和生物培養試驗相結合的方法，研究了在滴灌施肥條件下，化學氮肥施入土壤后的遷移、轉化規律以及對作物生長的效應，獲得了以下主要結論： （ 1 ）滴灌條件下水分以點源入滲土壤，水平和垂向的濕潤鋒均隨入滲時間的增加而逐漸變大，在入滲開始階段濕潤鋒的推進速率較大，隨入滲時間的延長，濕潤鋒的推進速率逐漸變慢。Function of compound layer in the course of nitriding and nitrocarburizing
層在滲氮及氮碳共滲中的作用According to the demand of the technology of gas nitriding, the author firstly put forward total demand analysis and systematic model - making for gas - nitriding furnace ' s temperature control system with uml in order to definite the temperature control system ' s functional requirement and the interaction of each object in this system on the basis of this idea. it ' s thought that the key step for realizing the temperature control system is the analysis and the design of the pid controller. considering that the gas - nitriding furnace has significant temperature lag, the author initially pointed out the opinion of realizing the system of temperature control by pid controller with pure lag compensation and then designed the parameter of pid controller with pure lag compensation and ordinary pid controller by matlab6. 5
這篇論文以作者本人在原工作單位的技術改造實踐中（即滲氮爐的技術改造）所遺留下來的技術問題為背景，根據氣體滲氮工藝的具體需要，首先提出了用uml對滲氮爐溫控系統進行總體的需求分析和系統實物建模以明確溫控系統的功能需求及各對象間的交互，在此基礎上分析得出溫控系統實現的關鍵所在即pid控制器的分析設計和實現，由氣體滲氮爐存在較大的溫度滯后這一特性，初步提出用帶純滯后補償的pid控制器來實現溫控系統的溫度控制，隨后藉助于matlab6 . 5平臺對帶純滯后補償的pid控制器和常規的pid控制器進行參數的設計與整定，進而在matlab6 . 5的simulink模擬環境中對基於兩種不同pid控制器的滲氮爐的兩種溫控系統的設計方案進行了模擬實現及模擬結果比較，結果表明，採用帶純滯后補償的pid控制系統的魯棒性較常規的pid控制系統好。分享友人
