phos 解釋
phosphate 磷酸鹽
  1. Abstract : the refining and modification methods of soybean phos phatide are commented in detail. at the same time, the applications of refined pho sphatide and modified phosphatide are briefly reviewed

    文摘:對磷脂的精製與改性方法進行了介紹，同時對目前市場上精製、改性磷脂產品作了簡要介紹。
  2. The identification of particles is provided in two ways. on one hand a charged particle detector is attached to phos to discriminate charged particles against neutral particles

    通常有兩種方法來鑒別光子和其他粒子：之一，在phos前放置一帶電料子反符合探測器cpv （ chargedparticlevetodetector ） 。
  3. On the other hand particle identification is provided during offline analysis by algorithms that examine the electromagnetic shower shape in phos to discriminate electromagnetic particles against hadrons

    之二，對phos中的簇射進行拓撲分析，從而區分電磁簇射和強子簇射。
  4. In the present work we have studied theses two complementary methods to identify photons in the electromagnetic spectrometer phos. we have first studied a new concept, ppsd ( phos pre - shower detector ), for the charged particle detector

    在我的論文中，分別針對這兩種方法給予改進：之一，用ppsd （ phospre - showerdetector ）取代cpv ，提高對中性強子的鑒別能力。
  5. The beam - test of china pin diodes at the cern sps accelerator produced satisfactory results. in addition, we studied the pin punch - through effect, and obtained the pin punch - through data with 18cm long pb wo4 crystal at the electron beam energies higher than 20gev for the first time, and these data gave valuable information to alice / phos

    在cern的sps加速器上的束流測試，得到比較滿意的結果；並對穿透效應做了實驗研究，首次獲得100gev粒子和20gev以上電子束的18厘米長pbwo4晶體探測器pin硅光管穿透效應實驗數據，為alice phos提供了有價值的參考資料。
  6. The prime aim of the experiment is to study the production of the quark - gluon plasma at high temperatures and high energy densities. phos ( photon spectrometer ) is the electromagnetic calorimeter of high granularity integrated in the alice experiment

    Alice的目標是：通過相對論重離子對撞，造成局部高溫高密條件，從而研究在此極端條件下物質的行為，探索新的物質形態? ?夸克-膠子等離子體qgp （ quarkgluonplasma ）及手征對稱性恢復的機理。
  7. One of the major goal of phos is to detect and identify direct photons, represent only about 5 to 20 % of the total photon yield. the photon background mainly comes from 0 and decays and misidentified hadrons

    Alice的光子譜儀phos （ photonspectrometer ）用於研究高能光子， phos的作用是：一，區分光子和其他粒子；二，區分直接光子和中性介子衰變產生的光子。
