Using thioacetamide as sulfur source, cus submicrometer hollow spheres consisting of nanoparticles were fabricated by thioglycolic acid assisted hydrothermal process. furthermore, in this experiment, sulfur source played important role on the morphology and phase of products
以硫酸鉛和硫化鈉為先驅體，在200v下反應24小時，是制備pbs納米棒的最佳條件；當用其它可溶性鉛鹽取代硫酸鉛為鉛源時，產物都為pbs納米顆粒。So the sliding mode variable structure controller was discussed, which has strong robustness against the disturbance, and the chattering phenomenon inherited from vsc was taken advantage to regular valve vibration for the purpose of avoiding coagulation on it, while precision of level control can be almost unaffected. but for the reason of control limitation, especially the acceleration insufficiency, the continuous time quasi - sliding mode vsc for one class of controllable system, as the substitution of ideal sliding mode control system, which was impossible to implemented, was researched, including the three essentials, reaching condition in particular, and the chattering ex - pression was given. furthermore, the effect to quasi - sliding mode motion and chatter - ing expression by extent disturbance was also analyzed
由於控制量相對受限制，並且主要體現在控制量加速不足方面，無法實現理想的滑模變結構控制，因此本文研究了一類能控系統在這種情況下的連續系統準滑模變結構控制，包括變結構控制三要素，尤其是到達條件；並且針對塞棒掛渣問題，給出了該情況下抖振的表達式；魯棒性方面，分析了外界擾動對準滑模運動的影響，並且給出了外擾作用下抖振的表達式。The applicator on the stick, a strip of synthetic proteins, then detects hiv antibodies in blood in 20 minutes or less
棒上的塗藥器是一條狀的人工合成的蛋白質，接著在血液中發現hiv抗體大約需要20分鐘。Carbon steel electrodes and rods for gas shielded arc welding
氣體保護電弧焊用碳鋼焊條和焊棒Specification for carbon steel electrodes and rods for gas shielded arc welding
氣體保護電弧焊用碳鋼焊條和焊棒的規范Firstly, sufficient conditions of lagrange stability for nominal unperturbed pendulum - like systems are derived based on the nonlocal reduction method. then the static state feedback controller design methods are presented for uncetain pendulum - like systems with time - varying norm - bounded parameter uncertainty to obtain robust lagrange stability. it is shown that the above problem can be reduced to the existence of the solutions to a set of lmis
在具體的推導過程中，首先基於非局部降階法，推導了高階標稱類擺系統lagrange穩定的充分性條件，然後基於此條件，針對具有范數有界參數不確定性的受控高階類擺系統，給出了使其魯棒lagrange穩定的狀態反饋控制器設計的充分性條件。Low - alloy steel electrodes and rods for gas shielded arc welding
氣體保護電弧焊用低合金鋼焊條和焊棒Even with unmodeled dynamics and bounded disturbances presented the controller has good robust performance without need of correct dynamic model and parameter estimation. the designed controller has applied to a model of three - generators hvdc system, and the simulations are performed with netomac
並且這種控制器的設計不需要有精確的系統動態模型，不需要未知參數來滿足線性依賴條件，不需要具體的系統參數估計，即使存在未建模動態和有界擾動，系統仍然具有很好的魯棒性。Control experiments of the inverted pendulum show that, comparing with pid and fuzzy control strategies, this rmbfc strategy possesses simpleness, validity. it not only reduces the number of fuzzy rules, quicken optimizing speed of mea and improve system fastness, but also avoids the disadvantage of general fuzzy controller that input variables are reduced at random from subjective view because disposal of analyzed data is objective. at the same time, yawp caused by strong coupling relation between variables is eliminated due to getting rid of abundant condition attributes, which makes rapid speed and robustness of system improved
摘要倒立擺系統的控制實驗表明，與pd和模糊控制策略相比， rmbfc控制策略簡單有效，不僅大大減少了模糊規則的數目，加快了mea的參數尋優速度，提高了系統的快速性，而且由於對被分析數據整體的處理是客觀的，避免了常規模糊控制從主觀角度隨意約簡輸入變量的弊病;同時，由於去掉冗餘的條件屬性，消除了因變量之間強禍合關系而產生的噪聲，使系統的控制特性得到了改善，快速性提高，魯棒性增強。Welding consumables. rods, wires and deposits for tungsten inert gas welding of non - alloy and fine grain steels. classification
