1. Maternal Health in economical backward rural areas in China is worrisome. It mainly presents with poor quality of maternal health service; 在经济落后地区农村妇女保健服务状况堪忧，主要表现在孕产期保健服务质量不高；
2. Maternal teratogens that hae been reported in association with cleft lip and palate include alcohol, maternal phenylketonuria, hyperthermia, hydantoin, trimethadione, aminopterin, and methotrexate. 据报道与唇腭裂相关的母体的致畸因素有酒精、母体的苯丙酮尿症、高热、乙内酰脲、三甲双酮、氨喋呤、氨甲蝶呤等。
3. The maternal weight, height, the gestational weeks at delivery, maternal abdominal circle, biparietal diameter and femur length are predictive factors for diagnosis of macrosomia. 孕妇体重、身高、分娩孕期及宫高、腹围、胎儿双顶径、股骨长径是产前诊断巨大胎儿的相关因素。
4. The 2 traits were simultaneously controlled by maternal additive genetic effects and maternal dominance genetic effects in kernel length and length/breadth ratio. 粒长和长宽比同时受到母体植株加性遗传效应和母体植株显性遗传效应的控制。
5. One example is maternal inheritance technology, in which modified genes pass down to only the seeds (the maternal line), not to the pollen (the paternal side). 方法之一是利用母性遗传技术：经过修饰的基因只会传给种子（母系），而不会传给花粉（父系）；
