excess phase 中文意思是什麼
excess phase
解釋
過量相位-
Under no excess pbo flux environment, the perovskite phase of pmnt single crystals were more stable than that of pznt, but it was found to be the decomposition of perovskite crystals into pyrochlore crystals at 1250. the pure perovskite pznt crystals prepared by the pbo flux method were thermodynamically metastable
在無pbo條件下pmnt晶體較pznt晶體穩定，但在1250附近的高溫下會發生向焦綠石相的分解反應； pznt單晶體是亞穩定的，在高溫時亦分解生成焦綠石相和pbo 。 -
With the three - dimensional ray - tracing program, the simulation of leo - gps occultation is given. the radio path of occultation observation is simulated, and then the excess phase delay is calculated. this work can be used for studying the effects of the neutral atmosphere and ionosphere on the occultation observations and evaluating the performance of the inversion techniques
本文介紹了無線電掩星技術的發展狀況和基本原理，圍繞無線電掩星技術及其應用研究展開諸多研究和探討，主要工作內容如下: 1 、利用全球三維射線追蹤程序，開展leo - gps掩星觀測的模擬研究，以計算掩星觀測時電波傳播路徑、計算大氣引起的附加相位時延等。 -
Effect of excess pbo and excess mgo on phase structure and microstructure of pmn - pt ceramics
陶瓷相結構及顯微結構的影響 -
By using ec membrane material as column packing, double - distilled water as mobile phase, the retention times ( tr " ) are measured with suitable inorganic and organic compound as solutes. 3. complying with the retention times, the partition coefficient of the solute ( ka " ) and the ratio of the surface excess concentration of solute ( ) with the concentration of the parent fraction ( cab ) are calculated
利用物理改性的方法研製了乙基纖維素（ ethylcellulose ，簡稱ec ）膜材料，並將其作為高效液相色譜柱的固體填料，以高效液相色譜模擬反滲透實驗平衡條件，以水為流動相，選擇合適的無機物和有機物作為溶質，測定乙基纖維素對它們的相對保留時間及平衡分配常數k _ a 。 -
I certainly hope that this is the case because, when the excess is in time absorbed, the necessary response on the upswing would also come at an accelerated pace, meaning that the unpleasant phase of the business cycle may be more short - lived than would otherwise be the case
我當然希望實際情況確實如此，原因是到了過剩的存貨及資本設備逐漸被吸收后，生產和需求同樣會加快面對經濟回升的調節，代表令人不快的經濟低沉時期可能並不如想像般長。 -
Effect of excess pbo and mgo on the fabrication of pmn - pt relaxor perovskite structure phase
弛豫復合鈣鈦礦相合成的影響 -
As a result 4 the rising annealing temperature induces si02 phase to form, also ivolves the formation of a si phase. in high - temperature - annealed sio ~, films the excess silicon atoms are present as si - si4 tetrahedra, randomly dispersed in the amorphous si02 matrix. photoluminescent spectra were observed for the samples excided by the laser whose wavelength is 365nm. the pl peak is located at about 445nm, which dose n ' t shift as the annealing temperature changes. as the annealing temperature is raised, the luminescent intensity increases. the phenomena suggest that the si - o - si bond as a defect center which is broken down by the stress at the si nc / si02 interface is the primary source of blue luminescence
這個陡的界面由於明顯的晶格結構的差別而有較大的應力。界面的形成伴隨著界面發光中心的增加，同時pl強度在l戶800有一個大的增強。這個結果提示我們，界面上h 0 s工鍵斷裂形成的nbohc應是藍光發射的主要原因。 -
The effect of excess pbo and excess mgo on phase structure and dielectric property of pmn - pt ceramics
陶瓷相結構及介電性能的影響 -
In the systems of pfw - pt, the effects of excess pbo, and fe2o3, the content pt on the phase structure, microstructure and dielectric properties of pfw ceramics were investigated respectively in detail. the results revealed that by adding excess pbo and fe2o3, not only the content of perovskite phase in calcined powders and sintered ceramics increased, but also the dielectric constant increased, especially
和「作為pw pt陶瓷助燒劑的研究中發現， pbo作為助燒劑，屬于液相燒結機制，在燒結中後期， pbo會停留在晶粒表面，因稀釋鐵電相而惡化介電性能。
