OBJECTIVES. Preterm male infants are at a disadvantage when compared with female infants regarding the incidence of respiratory and neurologic morbidity and mortality. At term, female infants from unlike-sex twin pairs have birth weights that are closer to their male co-twins than to girls from like-sex twin pairs.

该团队是以研究胎儿的并发症作为切入点的，他们发现早产双胞胎中常见的呼吸窘迫综合症的发病率与胎儿的性别有很大关系，同时，早产的异卵双胞胎中的女性胎儿将丧失她们先天的抵抗呼吸疾病的优势，其中原因便是男性胎儿的存在。

Common rolling plank is shown intense (orientaton of 0002) tool reference plane, after rolling of horn waiting for diameter, plank grain orientaton by original (change of orientaton of 0002) tool reference plane is; of orientaton of blame tool reference plane the existence after strain crack of common rolling plank is many twin brilliant, amount of brilliant of twin of drawing of direction of rolling of edge of plank of rolling of horn w

普通轧制板材呈强烈的(0002)基面取向，等径角轧制后，板材晶粒取向由原来的(0002)基面取向转变为非基面取向；普通轧制板材拉伸断裂后存在大量孪晶，等径角轧制板材沿轧制方向拉伸孪晶数量明显减少，等径角轧制有可能启动了新的滑移系，而拉伸孪生只是作为一种协调变形机制。

Changing formula forms of single-shear, twin-shear and three-shear yield strength criteria, show that many of yield strength criteria of rock and soil materials can be expressed by the τ8 = gf function forms unter the ordinary condition, and that the main differ ences of yield strength value will mainly forcus on the different function forms of gθσ among single-shear, twin-shear and three-shear yield strength criteria.

对岩土体常用的单剪屈服强度准则、双剪屈服强度准则和三剪屈服强度准则进行了系统的论述，通过对单剪、双剪和三剪屈服强度准则进行转化，指出岩土的屈服强度准则一般可表达为τ8=gf的函数形式，阐明了单剪、双剪和三剪屈服强度准则的差异主要表现在g函数的不同，并进一步解释了中间主应力σ2对岩土类材料屈服强度的影响。

In addition, the water model of a twin roll caster at a scale of 1:1 has been adopted; the level fluctuation in the pool was measured with the level senor. It was studied that the influences of the pool heights, flow rate and the submerged nozzle's typeson the level fluctuation in the pool. The experimental results provided a basis to further optimize feeding flow devices in the pool of twin-roll strip caster.
