When the two reactants were simply mixed by crush, they reacted violently and produced carbon spheres with a diameter of 50 - l00nm and sodium chloride ( nacl ) was encapsulated within the outer amorphous carbon shells, which could be confirmed by sem and tem. by annealing at 1400 ? to drive the encapsulated nacl away, hollow carbon spheres were left with a novel mesoporous structure, as presented in hrtem
實驗中將兩種反應物通過直接擠壓混合后加熱反應,得到的無定型球狀碳材料經tem照片證實直徑為50 - 100納米,而且中間包裹氯化鈉( nacl )顆粒; xrd等結果顯示,高溫退火併徹底清除nacl后形成的中空碳球已經部分石墨化。Liquid - solid extrusion of composite material is a new kind of metal forming process, which has been developed in recent years with a promising practical application prospect for its simple working procedure, low cost and good workpiece performance. through a lot of experiments, the optimization and chosing method of key process parameters ( pouring temperature, mold warm - up temperature, impregnating pressure, impregnating time ) has been mastered. under the precondition of appropriate chosing these parameters, the effective control of extrusion velocity is the key of mading good workpiece. but the control of extrusion velocity remains a handwork, and it is heavily affected by such uncertainties as a handler ' s knowledge and skill about the process. in order to solve the problem, the automatic control of the extrusion velocity is studied, and a computer control system is also designed under existing condition
通過大量實驗,已掌握了關鍵工藝參數(熔液澆注溫度、擠壓模預熱溫度、浸漬時間、浸漬力)的優化選取方法。在合理選取關鍵工藝參數的前提下,擠壓速度的控制是成形出質量良好製件的關鍵。但是,目前對于擠壓速度的控制仍停留在手動控制階段,利用該工藝制備管、棒材製件的成功與否受操作者對該工藝及其設備的經驗及熟練程度等不確定因素影響很大。Over activity of the sympathetic nervous system causes tension, sleeplessness, and ultimately all deadly diseases like cancer. these diseases are caused by the constricted plexuses that have been drained of their energy. if you can make the parasympathetic dominate the right side, then we can antidote the effects of over activity
右交感神經過度活躍會造成神經緊張失眠肝臟過熱會引起皮膚病及食欲不振,及各種致命的疾病,如哮喘糖尿病腎臟失去機能血癌心臟病,以及身體左部癱瘓,這都是由於能量中心受擠壓過甚,以至能量衰歇而造成的。The disposal of the valves and intake manifold structure not only affect fresh air charge but airflow in the cylinder, which immediately affect combustion efficiency and the performance of dynamic, economic and emission. the structure of the air distributing institution has influence on charging efficiency and the noise of engine. the combustion chamber affects compression scale which has great influence on dynamical performance ; f / v which affects the exhaust of hc ; squash area and clearance which have great influence on the intensity of squash
氣缸蓋的氣門排列方式與氣道結構形式影響進氣充量和氣流在氣缸內的運動,從而影響了燃燒效率,對整機的動力性、經濟性以及排放都有直接的影響;配氣機構的形式影響充氣系數和整機噪聲等;缸蓋燃燒室決定了影響整機動力性能的壓縮比,影響hc排放的f / v和對擠流起決定性作用的擠氣面積以及擠氣間隙,所以燃燒室對整機動力性、經濟性、排放等都有重要的影響;氣缸蓋是整機熱負荷與熱應力最大的部件之一,熱負荷過高將不利於發動機壽命以及可靠性的提高。After 100, 000 to one million years, depending on the original mass of the star, it ceases altogether, and the remnant star settles down as an extremely dense and hot white dwarf ? a stellar ember crushed by gravity into a nearly crystalline orb about the size of earth
經過10 ~ 100萬年(取決于恆星的原始質量) ,恆星風將驟然終止,而恆星的殘留物會演變成極緻密高熱的白矮星:一種被重力擠壓成地球般大小,近乎晶質球體的恆星遺骸。The extruded az91d alloy was heated continuously and soaked at constant temperature. then it was quenched in the water and the instant texture at high temperature was acquired
首先對經過擠壓形變的az91d鎂合金分別進行連續加熱及等溫保溫,然後水淬快速激冷固定其高溫瞬時組織。Subsequently, the capabilities of materials were heighten when density was improved. when materials relative density reached 93. 35 %, their conduct could reach 58. 62 % iacs, their hardness could reach hb135. materials relative density could reach 97. 45 % when materials were extruded thermally
當材料的緻密度達到93 . 35時,其布氏硬度為hb135 ,電導率為58 . 62 iacs ;經熱擠壓后,材料的緻密度可達到97 . 45 ,其抗拉強度為521 . 70mpa ,在課題研究范圍內表現出了較好的性能。分享友人
