Department of Scientific History and Archaeometry; Graduate University of Chinese Academy of Sciences; Beijing 100049;4.Institute of Archaeology; Chinese Academy of Social Sciences; Beijing 100710; China;The fabrication technologies in terms of phase composition,structure,firing temperature,porosity,density and water permeability of ceramic water pipes and contrastive ceramic tilesexcavated from Anyang Yin Ruins of Shang dynasty were studied by X-ray fluorescence,X-ray diffraction and dilatometer,respectively.It was found that the contents of CaO,K2O,MgO and P2O5 in CWP were relatively higher than those in contrastive CT.The difference was further confirmed by the mass ratio of flux...

采用X射线荧光、X射线衍射、热膨胀等分析手段对比研究了安阳商代陶水管的制作工艺，发现陶水管化学成分中各类熔剂的质量分数均略高于对比陶片中熔剂的质量分数，CaO、K2O、MgO等助熔剂与A l2O3的质量比进一步证实该现象，而这种差异性则外在地表现为陶水管的气孔度低于对比陶片以及陶水管热膨胀曲线中出现玻璃化现象，该结果表明陶水管原料应为一种易熔粘土，或者在沉淀粘土中人为地掺和了草木灰类掺和料，这有利于陶水管烧制与成型，有助于熔剂在熔融状态下，较好地进入陶水管中的空隙，使陶水管变得更加致密，一定程度上有利于防止陶水管的渗水，显示出陶水管制作工艺的特殊性。

Secondly, by using the connection, we prove that the minimal continuous semi-flow is the minimal continuous flow if its time-one map is open, and for any minimal continuous semi-flow, there is an invariant residual set such that the restriction to the set is a minimal continuous flow.

为此，我们首先建立了它与其时间1映射极小集的联系；然后，利用这种联系证明了：若时间1映射为开映射，则它是极小的连续流，并且一般地说来，对任意极小连续半流，存在不变的剩余集，使得它在这不变集上的限制是极小的连续流。

Although it is based on reality, the school of art has a broad choice of subjects, a great freedom in composition, and a combined use of symbolism, euphonium and humor in the expression of ideas. As for skills, it gives an emphasis on the realism of details and the romanticism of the whole and in effect provides the audience with an infinite space for imaginations.

程亚杰从他维也纳老师胡特那里承继过来的"想现实主义"严格地讲，更倾向于浪漫主义的创作方法，它虽然有现实的意义根据，但创作主体有更大的物象选择和组合的自由，画面背后的意图更多的是通过象征、隐喻和幽默的营构来反映；在表现手法上则是重视细节刻画的写实和整体构成的变实，这种写实和变实的交错使用给幻想留下了超时空自由组合的广阔空间。

For the one-dimensional p-Laplacian with indefinite weights, four sequences of periodic and anti-periodic eigenvalues are given by introducing the rotation number function, and these eigenvalues are the endpoints of the preimage intervals of the rotation number function at nonnegative integers.

The function of enclosure was to enable the dispersed fields of a landowner in a single parish to be concentrated without increasing and decreasing in the proportion before and after enclosure; Enclosure was the precondition of the estate structure in the late 19th century, while the main motivation and approach of that was social mentality and estate market; In the estate structure of late 19th century, agent was the main actor to manage the large and middle estates; Landowner, tenant farmer and agricultural labour affected and restricted each other, which was full of tender feelings.

圈地运动的作用只是使土地所有者在单个教区内分散的土地几乎数量不变地集中到一起；小土地所有者不仅没有消失，而且在1780-1832年间圈地进行最为剧烈的时期出现了数量增加的状况；圈地运动为大地产的形成创造了前提，十八、十九世纪土地流动的主要动因和途径则是大众的心态和市场的激励；在19世纪晚期地产结构中，大、中地产的管理主要是通过代理人体系进行有效的运营；地主、农场主、农业工人三者之间相互影响、相互制约，充斥着温情。

In this project, we study the theory of higher order differential equations in Banach spaces and related topics. We solve an open problem put forward by two American Mathematicians and two Italian Mathematicians concerning wave equations with generalized Weztzell boundary conditions, introduce an existence family of operators from a Banach space $Y$ to $X$ for the Cauchy problem for higher order differential equations in a Banach space $X$, establish a sufficient and necessary condition ensuring $ACP_n$ possesses an exponentially bounded existence family, as well as some basic results in a quite general setting about the existence and continuous dependence on initial data of the solutions of $ACP_n$ and $IACP_n$. We set up quite a few multiplicative and additive perturbation theorems for existence families governing a wide class of higher order differential equations, regularized cosine operator families, regularized semigroups, and solution operators of Volterra integral equations, obtain classical and strict solutions having optimal regularity for the inhomogeneous nonautonomous heat equations with generalized Wentzell boundary conditions, gain novel existence and uniqueness theorems,which extend essentially the existing results, for mild and classical solutions of nonlocal Cauchy problems for semilinear evolution equations, present a new theorem with regard to the boundary feedback stabilization of a hybrid system composed of a viscoelastic thin plate with one part of its edge clamped and the rest-free part attached to a visocelastic rigid body. Also we obtain many other research results.

在本研究中，我们对Banach空间中的高阶算子微分方程的理论以及相关理论进行了深入研究，解决了由美国和意大利的四位数学家联合提出的一个关于广义Wentzell边界条件下的波动方程适定性的公开问题，恰当地定义了Banach空间中的高阶算子微分方程Cauchy问题的算子存在族及唯一族，建立了齐次和非齐次高阶算子微分方程Cauchy问题适定性的判别定理，获得了关于高阶退化算子微分方程的算子存在族、正则余弦算子族、正则算子半群、Volterra积分方程解算子族的乘积扰动和混合扰动定理，得到了关于以依赖于时间的二阶微分算子为系数的一大类非自治热方程非齐次情形下的时变广义Wentzell动力边值问题的古典解、严格解的最大正则性结果，获得了半线性发展方程非局部Cauchy问题广义解和经典解存在唯一的判别条件，从实质上推广了现有的相关结果；得到了一部分边缘固定而另一部分附在一粘弹性刚体上的薄板构成的混合粘弹性系统的边界反馈稳定化的新稳定化定理，还建立了一系列其他研究结果。

The nanoplex were smaller than the unmodified nHAP; thelipiodol/nanoplex emulsion, with the mean diameter at 75±11.8nm can disperse moreuniformly and be more soluble and stable, contrary to the unmodified nHAP and nanoplex Conclusion: Nanoplex/pDNA mass ratios greater than 15 had exhibited completepDNA absorption onto positive charged polyplex and pDNA protection from thedestruction of nucleinase in rabbit serum. Unmodified nHAP may can\'t induce effectivegene delivery.PartⅡThe construction of the recombint eukaryotic expressive vector ofwild-type human p53 and RbObjective: To construct the recombint eukaryotic expressive vector of wild-type humanp53 and Rb by utilizing the theory of molecular medicine.

结果nHAP颗粒本身大小小于100nm，但由于颗粒表面本身带负电，不能包括有效地结合及保护DNA；经Ca~(2+)修饰后，颗粒可带正电，可一定程度地结合和保护DNA，但聚合物本身的中性电与带负电的细胞膜结合，而且本身的颗粒则变地容易聚集而成为很大的颗粒，也不利于细胞的吞噬；经PLL修饰后，颗粒溶解性提高，直径变小，表面带正电，电泳结果显示PLL-nHAP颗粒可包括有效地结合和保护DNA免受兔血清的破坏，而且复合物表面的正电也包括有利于与细胞膜的结合与吞噬。

She remained nearly always in her second-floor chamber, shivering in her chair, or stretched languid and feeble on her bed, while her husband kept his daily watch at the door--a duty he performed with so much the greater willingness, as it saved him the necessity of listening to the endless plaints and murmurs of his helpmate, who never saw him without breaking out into bitter invectives against fate; to all of which her husband would calmly return an unvarying reply, in these philosophic words:-- Hush, La Carconte.

她几乎总是呆在二楼上她的房间里，哆嗦着坐在椅子里，或有气无力地躺在床上，而她的丈夫则整天在门口守望着，他非常愿意干这差事，这样，他就可以躲开他老婆那没完没了的抱怨和诅咒。因为她每一看见他，就必定喋喋不休地痛骂命运，诅咒她现在这种不该受的苦境。对这些，她的丈夫总是用不变地富于哲理话平心静气地说：别说了，卡尔贡特娘们！
