THE CORRELATION OF ANTITROPHOBLAST ANTIBODY, EMAB AND HCG-AB WITH IVF-ET PREGNANCY OUTCOMEYANG ZONG-ZHI, SONG DONG-PO, ZOU SHU-HUA, et al（Medical and Health Care Center For Women and Childen of Qingdao, Qingdao 266011, China）［ABSTRACT］ObjectiveTo assess the effect of antitrophoblast antibody, EmAb and HCG-Ab on in vitro fertilization and embryo transfer outcome.MethodsThis study included 140 infertility women of unexplained reasons, salpingemphraxis and/or male factor undergoing IVF-ET, of whom, 31 with repeated failure of implantation; 26 with biochemical loss of pregnancy; 18 with clinical pregnancy loss. Sixty-five with clinical pregnancy served as control group.

目的 探讨抗滋养细胞膜抗体、抗子宫内膜抗体、抗HCG抗体对体外受精-胚胎移植妊娠结局的影响方法选择2002年1月～2007年7月在本生殖医学中心由于不明原因性不育、女方输卵管因素和男方轻度少弱精子症因素不育而接受IVF-ET治疗的妇女140例，其中次植失败31例，生化妊娠丢失26例及临床妊娠丢失18例，持续妊娠65例。

One of the most important factors responsible for the low yields is the lack of adequate nutrition and fertilization programs. Other factors are nematodes and black sigatoka.

低产重要原因之一是养分不足和缺少施肥计划，其次为线虫和香蕉叶斑病。

Temporal and spatialcorrelation of Soil moisture under vertical direction was affected by some factor such asmeteorology, land use and fertilization measures. All siol moisture in different layers hastemporal and spatial correlation when soil moisture fluctuates of surface layer becausestability, but influence ability of each factor is not the same. For example, meteorologyhas most strong impact on temporal and spatial correlation of soil water content.

在气象条件较稳定的情况下，不同植被覆盖和不同施肥措施下各土层含水量之间都具有较强的时空相关性，随着气象条件波动加剧，各土层土壤含水量的时间相关性和空间相关性都降低；植被因素相对气象条件对各土层含水量的时间自相关性影响较小，而对各土层土壤含水量之间的空间相关性影响较大，裸地和农田各土层土壤含水量之间的空间相关性相对林地和草地较弱；不同的施肥水平都削弱了土壤各土层含水量的时空相关性。
