针对以往监测模型预测精度难以保证的的问题，本文在分析比较了几种土石坝安全监测预报模型的基础上，提出了一种新的安全监测预报模型——遗传回归模型，该模型通过遗传染色体对建模因子进行优选，并在适应度函数中综合考虑模型拟合精度与预测精度平衡。

The saturation equals 1 in saturated region.The piezometric tube waterhead equals position head by neglecting the effect of capillarity in unsaturated region.So the nonlinear parabolic equation of seepage flow will degenerate to Laplace equation about piezometric tube waterhead in saturated region and convective equation about saturation in unsaturated region respectively.

将渗流域分为饱和区与非饱和区，为避免研究复杂的多相流问题，可以认为非饱和区是与大气相通的，则测压管水头中的压力与大气压相等，使测压管水头等于位置水头，从而渗流控制方程在两个区域中分别退化为关于测压管水头的拉普拉斯方程和关于饱和度的对流方程。

Stamens inserted at base of corolla tube; filaments connate into a tube; anther appendages incurved; pollinia 2 per pollinarium, pendulous.

为了满足液氦温区分离型二级脉管制冷机第二级预冷的需要，设计制作了1台20～40K温区单级大功率脉管制冷机。

The results show that the single-layered neural tube fails to form and the neural crest cells remain at the lateral regions in the explants with NTDs. However, the patterning of the neural tube is not affected as indicated by the normal expression of the preneural genes.

结果显示神经管闭合缺陷的移植体不能形成单层化的神经管，并且神经晴细胞滞留在侧面区域不能向背侧中线迁移，而对神经前体标记基因的检测显示神经管的背腹图式形成并未受到影响。

The results indicate that there are vortexes, shocks and expansion waves outside the multi-tube PDE. In addition, the results might be referrible to research the characteristics of the flow-field outside multi-tube Pulse Detonation Engine.

计算结果表明，此多管脉冲爆轰发动机黏性外流场中存在旋涡及多道相互作用的激波与膨胀波，该结果对多管脉冲爆轰发动机外流场特性研究具有一定的参考价值。

When the Heater transfer heat energy by water ,the reflexible and focusing evacuated tube can be inserted into water tank directly or joins water tank by tie-in,it lie on the diameter of the reflexible and focusing evacuated tube because that make assembling to be possible or not.

这种内置的反射镜面，既具有太阳能热水器反射板提高阳光利用率的效果，又避免了外置反射板积雪、积垢、增大风阻的弊端，其成本更得以大幅下降。
