多产性

本研究证明ESR，FSHβ对多产性效应明显，且多态性丰富，故可以ESR，FSHβ基因作为分子标记对多产性开展标记辅助选择工作，提高多产性水平。

In this research the effects of ESR and FSH β on prolificacy is proved to be obvious , and they are abundant in polymorphism . So we can use them as molecular marker in MAS in order to improve the level of prolificacy .

年龄是影响多产性的一个重要因素，头胎的总产仔数和产活仔数均低于经产胎。

Age is one important factor influencing of prolificacy , the TNB of first parity is less than the still parity , so does in NBA . 7 .

根据现有理论，成功模因具有三大特点：长寿性、多产性和保真性。

According to Memetics , successful memes have the following three features : longevity , fecundity and copy-fidelity .

模因是一种文化进化单位或信息复制因子，具有长久性、多产性和保真度三个主要特征。

Meme is a unit of cultural evolution or a replicator of information with the three main features of longevity , fecundity and copying-fidelity .

但是这并不意味着所有的语言单位都可以成为模因，因为成功的语言模因必须具备一定的特点，即高保真度、多产性和长久性。

But this does not mean that all of them can become memes , for there are some conditions . A successful language meme should have the characteristics of fidelity , fecundity , and longevity .

在评价医疗卫生服务效率的方法中，数据包络分析法是运用较多的方法之一，适合对多投入&多产出的区域性医疗卫生服务的效率进行评价。

Data Envelopment Analysis is one of the methods , which are used to evaluate the efficiency of medical and health care . And it fits for efficiency evaluation of medical and health efficiency with multi-inputs and multi-outputs .
