- early filling fraction 早期充盈分数
- Objective To study the relationship between the degree of mitral stenosis (MS) and atrial filling fraction (AFF). 目的研究二尖瓣狭窄程度与左房充盈分数的关系。
- For a certain radius and filling fraction, the width of the first band gap is the largest when the other radii are equal. 当确定椭球体的某一个半径和填充率时，第一禁带的最大值出现在另2个半径相等的情况下。
- R ratio to total posterior wall excursion(R/PWE) was also decreased,while the slow filling fraction(SFF) and arterial filly fration(AFF) were increased correspondingly. 而慢充盈分数 (SFF) ,心房充盈分数 (AFF)却相应增加。
- Applying K2SO4 basal fertilizer, spraying urea in early filling stage and spraying Fengyousu after an-thesis can increase its yield and improve baking quality. 基肥施硫酸钾、灌浆初期喷尿素和开花期喷丰优素对提高产量和改善面包烘焙品质都有促进作用；
- For Sm_yFe_xCo_(4-x)Sb_(12) compounds, the electrical conductivity and carrier concentration decreased with increasing Sm filling fraction. The Seebeck coefficient increased with increasing temperature and Sm filling fraction. 对于Sm_yFe_xCo_(4-x)Sb_(12)化合物,随着Sm填充分数y的增加,Seebeck系数增大,载流子浓度及电导率降低;
- When wheat was treated with Cd2+ of different concentrations,the changes in enzymatic and non-enzymatic antioxidative system at jointing,heading,early filling and middle filling stage was studied. 以不同Cd2+浓度对土培小麦进行处理;分别在拔节、抽穗、灌浆初期以及灌浆中期;分析不同浓度Cd2+胁迫下活性氧及酶促和非酶促抗氧化系统的变化.
- The drought during the early filling stage accelerated wheat filling velocity and increased wheat grain weight, while the drought during the late filling stage restrained the wheat filling process. 灌浆前期干旱有促进灌浆和增加粒重的作用，而后期干旱对小麦灌浆有抑制作用，全程干旱使小麦的灌浆速率明显减弱。
- The senescent frequency contained the decline rate of leaf area, dry matter and chlorophyll content at the early filling phase and thus can be an indicator of premature senescence. 衰老频度涵盖了灌浆结实期单位时间内高效叶面积、叶干重、叶绿素含量3个指标的下降率，可作为判断早衰发生的量化指标。
