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。

Based on the physical characters that the temporary magnetic material can absorb magnetic force nearby and change the distribution of magnetic field,and in combiniation with structural optimization of the semi-adverse current chest,a new type magnetic separator which can make the magnetic mineral apar has been developed and the pilot test was finished.

It shows that gypsum is stable at the pressure less than 407 MPa; and then gypsum begins to dissolve with the increasing pressure. Gypsum stops dissolving and phase transition happens (gypsum-bassanite) to some degree. After phase transition, bassanite disappears with the rising pressure.

结果表明：压力小于407 MPa时，石膏的形态无明显变化；随着压力的升高，石膏开始溶解，溶解至一定程度，石膏发生了向半水石膏转化的相变；相变完成后，半水石膏继续溶解至消失。

Fauchelevent belonged, in fact, to that species, which the impertinent and flippant vocabulary of the last century qualified as demi-bourgeois, demi-lout, and which the metaphors showered by the chateau upon the thatched cottage ticketed in the pigeon-hole of the plebeian: rather rustic, rather citified; pepper and salt.

割风正是前一世纪那种轻浮不得体的文词所指的那种&半绅士半平民&的人，也就是达官贵人在对待贫寒人家时所用的那些形容平民的隐语所标注的&略似乡民，略似市民，胡椒和盐&。

All looked colder and darker in that visionary hollow than in reality: and the strange little figure there gazing at me, with a white face and arms specking the gloom, and glittering eyes of fear moving where all else was still, had the effect of a real spirit: I thought it like one of the tiny phantoms, half fairy, half imp, Bessie's evening stories represented as coming out of lone, ferny dells in moors, and appearing before the eyes of belated travellers.

在虚幻的映像中，一切都显得比现实中更冷落、更阴沉。那个陌生的小家伙瞅着我，白白的脸上和胳膊上都蒙上了斑驳的阴影，在—切都凝滞时，唯有那双明亮恐惧的眼睛在闪动，看上去真像是一个幽灵。我觉得她像那种半仙半人的小精灵，恰如贝茵在夜晚的故事中所描绘的那样，从沼泽地带山蕨丛生的荒谷中冒出来，现身于迟归的旅行者眼前。

To analyze results through statistical methods, and possess significant difference when P.05(a=0.05). To observe that effect of volume of distilled water on synthesis of hemihydrated gypsum is bigger, and the effect better when distilled water: raw materials as 150ml:100g; whereas effect of Calcium Chloride and sodium Succinate smaller, and the effect better when Calcium Chloride: dehydrated gypsum as 1:2, sodium Succinate as 0.75%.

采用统计学方法进行分析，P＜0.05时具显著性差异(a=0.05)结果：在试验中观察到蒸馏水量对半水石膏合成影响较大，当蒸馏水与原料比为150ml：100g时效果较好；而氯化钙及丁二酸钠影响较小，当氯化钙与二水硫酸钙质量比为1：2，丁二酸钠为0.75％时效果较好。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
