IHF怎么读

Computer programmes are worked out in this paper. Using the programmes, the critical rotation rate of chopping drum of field straw chopper JH-100* IHF-150, JHF-130 are calculated particularly and main factors, influencing critical rotation rate are analysed.

应用此程序计算了设计的JH100，JHF150，JHF130秸秆还田机刀轴系统的临界转速，分析了影响临界转速值的主要因素。

For the semilinear differential equations with nonlinear term f ( u), this paper introduces a simplified finite element method, called as interpolated coefficient finite element method, which requests that/(?/,) is replaced by interpolation Ihf ( uh) in numerical computation.

本文针对半线性微分方程中含有的非线性项f（u），在有限元计算中将插值I hf（u h）代替f（u h），从而得到一种简化的有限元法-插值系数有限元法。

Objective: To explore the effect of the intracoronary transfer of autologous mononuclear bone marrow cell ( MBMC) on ischemic heart failure ( IHF) and change of plasm levels of natriuretic peptides after MBMC implantation.

目的：观察骨髓单个核细胞（mononuclear bone marrow cell，MBMC）移植对缺血性心肌病患者左心功能及血浆利钠肽的影响。
