双层的

Nevertheless, induced bilevel programming models for the former category usually belong to a subject of nondifferentiable optimization problems, whereas that for the latter category becomes the continuously differentiable optimization problems.

此文首先从模型和算法的角度总结了有关这类问题已有的研究成果，接着介绍有关这方面的最新的研究进展，即如何把用户基于平衡原则下的交通网络优化问题的双层规划模型统一地转换为一个连续可微的单层最优化问题，并设计统一的算法。

UV-Vis spectra show that the absorbance values at characteristic wavelengths of the multilayer films increase almost linearly with the number of chitosan/PTA bilayers, suggesting that the deposition process is regular and highly reproducible from layer to layer. XPS and FTIR spectra confirm the incorporation of chitosan and PTA into the films. AFM images indicate that the surface of the multilayer films is rough. The result of CV shows that the multiplayer films maintain good electrocatalytic activity of phosphotungstate acid.

UV-Vis结果显示多层膜在特征吸收峰处的吸光度数值随膜双层数增加逐渐增大，呈良好的线性关系，表明多层膜是均匀组装的；XPS和FTIR结果证实了壳聚糖和磷钨酸被组装到膜上，AFM图形显示膜表面有一定的粗糙度，CV结果说明多层膜保留了磷钨酸的电化学性质。

The two specular highlights will give an optimal light reflection to your object in order to show in a very soft and for the human eye pleasureful way the shapes of you objects.

双层高光将给你的物体一个非常理想的灯光反射，它以一种非常柔软的，悦目的方式来体现物体的形体。

Results 12 cases, there were 12 isolated subperiosteal hematoma of the skull, all in the top three weeks ~ March 2 cases, six months in March ~ 9 cases, one cases of more than half a year. 3 weeks to 3 months of hematoma, capsule machine was of uneven thickness of the line, a higher density strips; March ~ subcapsular hematoma of more than half a year with irregular thickening of the skull-shaped double-decker was changed after Hematoma shaping a longer period of time to become part of skull.

结果：12例中，共存在12个孤立的颅骨骨膜下血肿，全部位于顶部，3周~3月2例，3月~半年9例，半年以上1例。3周~3月的血肿，包膜机化呈厚薄不均的线状、条带状更高密度影； 3月~半年以上的血肿包膜不规则增厚与颅骨呈双层状改变，经过更长时间的塑形血肿成为颅骨的一部分结论： CT能准确诊断颅骨骨膜下血肿机化，并充分显示其大小、部位。

All results showed that HIV〓 disrupts the stability of negatively charged POPG membrane, but did not influence zwitterionic POPC membranes.

上述四个方面的实验结果都显示HIV〓只破坏带负电荷的POPG脂双层膜的稳定性，但几乎不影响电中性的POPC脂膜的正常状态，说明ⅢV〓发挥其功能的一个必要条件是融合肽和脂膜之间必须存在静电吸引力。

Countries such as Japan, with two-tier workforces in which an army of temporary workers with few protections toil alongside mollycoddled folk with many, will need to narrow that disparity by making the latter easier to fire.

想日本这样的拥有双层劳动力构成，而临时工不仅得不到保护，还同其他待遇好的员工做同样艰苦的工作的国家，将需要通过严格上层员工的裁汰制度以缩短劳动力间的差距。

The double-layered air-inflated membrane forming a "floating cloud" with a diameter of 107m was built by linking a framework in the shape of a truncated cone in the center and a ring truss with 48 upper radial cables and as many lower radial cables, covering them with PTEE coated glass fiber membrane and introducing air into the double-layered membrane to achieve an internal pressure of 300mmHG.

双层充气膜形成了一个直径107m 的、以锥台状框架为中央支撑的&浮云&。在中央的锥台状框架与外围的环形桁架之间，上、下各有48根辐射状的素相连。

According to the designers, we have the whole teaching and research floor space requirements and corresponding open-grade scale modeling and designing and producing a wide range of sizes and specifications for the single fire glass severed section steel profile system framework,Venetian glass partition intermediate fire double steel profile system framework, a special glass doors of the fire modeling framework of steel profile,Implicit practices and frame of the fire box glass roofs, and fire systems steel curtain wall of steel framework Profiles Profiles framework.
