  1. The third aspect : as is known, the main reason of proposing zm model is to improve the properties of effective nucleon mass in qhd - i model

    第三個方面， z翩的提出主要是為了解決qhd中核子有效質量在高溫下的陡降問題
  2. Here, through expanding the nonlinear coupling constant, we have discussed this mechanism. in addition, we find that the phase transition at high temperature in qhd - i model has been suppressed in zm model

    本文通過展開非線性耦合常數，並逐階求解進行分析，討論了這一改善的機制，並發現qhd i模型在高溫下的相變機制在zm模型中遭到了抑制
  3. The relativistic hadronic model theory includes quantum hadrodynamics ( qhd ) and its mean field theory

    相對論性的強子動力學模型理論包括量子強子動力學理論（ qhd ）和它的平均場求解方法。
  4. In qhd theory, there are many hadronic models. among them, qhd - i model ( also called walecka model ) is most fundamental

    在qhd理論諸多理論模型中， qhd -模型（也稱walecka模型）是最簡單，也是最基本的。
  5. Here by applying qhd - i model and zm model, we have mainly discussed the effective nucleon mass in hot and dense nuclear matter

    本文主要採用（ qhd - ）模型和zm模型，討論了在熱密核物質中核子有效質量的變化規律。
  6. So it ' s very difficult to study nuclear phenomenon with qcd. while qhd is a low energy effective theory which describes hadronic physics very well

    在當前， qhd理論是一個很好的研究中低能區強子物理的有效理論，其物理描述簡單，直觀。
  7. The first aspect is that, in qhd - i model, it is generally accepted that there is a first - order liquid - gas phase transition, but the properties of effective nucleon mass under this phase transition have n ' t been thoroughly studied

    第一個方面，採用qhd -模型，可得出核物質在低溫下會有一個汽液相變，其它的強子模型也都能給出這一相變。
  8. Abstract : the baghouses of the 6th company of qhd port are not proper for removing coal dust. it has been improved by selecting new filter material, cleanig accumulated particulate matter with pulsation jet of air, which makes a good result for removing coal dust

    文摘:秦皇島港務局第六港務公司原轉接塔處的布袋除塵器不適合煤炭除塵，通過選用新型濾布、採用脈噴吹清灰等措施對除塵器進行技術改造，對于煤炭除塵取得良好效果。
