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 others are Mucuna sempervirens,Parthenocissus trcuspidata,Wistaria sinensis Sweet in turn.According to the distinction of ecological functional of these four plants,the kind of plants which should be chosen under various ecological environment conditions or for different demands of ecological function of the plants were given.1. The most suitable plants for the area which get serious pollution such as factory,roadway and so on is Mucuna sempervirens.the other plant which more suitable is Rosa banksiae Ait.2. The most suitable plants for the hospital and the area for the children and the old is Mucuna sempervirens. And we can also select Parthenocissus trcuspidata.3. In the green area of modern enterprise that produce precision instrument,Rosa banksiae Ait is the best selection.4. Rosa banksiae Ait is the most suitable plants in resident green area. Planting Mixed with Mucuna sempervirens has better effectiveness.

以四种植物的生态功能性差异评价为依据，提出不同生态环境条件下和对植物不同的生态功能性要求的垂直绿化应选择的植物： 1 在道路、工厂等污染较严重的地区搞垂直绿化，最合适的植物是油麻藤，其次可选择木香； 2 医院及儿童、老人活动区的垂直绿化首选是油麻藤，其次是爬山虎； 3 生产精密仪器的现代企业绿地，垂直绿化植物选择以木香为首选，可结合大面积的爬山虎墙面绿化； 4 居住区绿地的垂直绿化植物选择以木香最符合要求，再以油麻藤进行混植，效果较好。

Disk and apophyseal joint injuries are usually associated with limitation of motion at one or more vertebral.

过度扭转、旋转和挤压是最常见的下腰痛损伤因素。

When the miracle of metamorphosis is complete,the eclosing,or rupture of a chrysalid,is one of nature's most sublime moments.It happen in secret,hidden under leaves,and rarely witnessed by humans.

当蜕变奇迹完成后，蝴蝶破蛹而出是大自然最神奇的时刻之一，这一变化常在叶下秘密进行，人类难看到。

2 Mm, ciliolate. Panicle lax to contracted, 4–10 × 0.5–5 cm; branches solitary, lowermost 1.2–3 cm, erect or spreading, bare in lower 1/5–1/3, scaberulous, branchlets appressed, main axils often pilose; pedicels 0.5–3 mm, shorter than spikelet.

对收缩疏松的圆锥花序， 4-10 * 0.5-5 厘米；分枝单生，最下1.2-3厘米，直立或开展，裸露在下部1/5-1/3，微糙，小枝贴伏，主要腋通常具柔毛；花梗0.5-3毫米，短于小穗。

"Wire Bonder" is the most costive equipment in the investment of IC packaging; and the packaging quality, cost and delivery are concerned most in the assembly processes. An inappropriate process scheduling may result in the wastes of resources and assembly bottleneck. Manager must allocate the resourcesappropriately to adapt the changeable products and production lines.

在半导体封装制程中，以焊线制程所投入的设备及成本最大；相对的，其制程的安排亦主导著封装的品质、成本与交货速度，若排程或派工决策不良，则将导致资源的浪费，与制程瓶颈的产生，因此在有效的资源分配的前提下，管理者必须即时分配资源以应付产品快速转换的需求，进而达到最适的排程与派工规划。
