It's a changing world. Some two and a half million people now dot the plains once dominated by Pawnee and Osage Indians; and where the Oregon and Santa Fe Trails were forged, cities like Kansas City (which sits smack dab on the Kansas-Missouri border), Topeka, and Wichita grow.

这是变化的世界，250万人现正定居在原Pawnee 和奥色治印地安人统治的土地上，并且在那里俄勒冈和圣达菲的经历正在重演，象堪萨斯市（座落在堪萨斯州和密苏里州的边境上）、托皮卡以及威奇托的壮大，虽然本州的经济仍然以农业为主，但她以其温和的态度以及拥有丰富的资源城市吸引着大量的新定居者，他们带来了新的资源以及比其引以自豪的牛镇更有价值的世界公认的好处。

Carleman不等式及其在最优控制问题中的应用.Optimal control theory of distributed parameter systems mainly includes: Pontryagin's maximum principle; controllability; Hamilton-Jacobi equation (i.e., dynamic programming equation); time optimal control, etc.In this dissertation, we establish Pontryagin's maximum principle of optimal control problems governed by some nonlinear differential equations (parabolic differential equations, elliptic differential equations and 3-dimensional Navier-Stokes equations), which in particular could have local solut...

在这篇博士论文中，我们建立了非线性微分方程(包括抛物型微分方程，椭圆型微分方程以及3维Navier-Stokes方程)最优控制问题的庞特里雅金最大值原理，特别地，这些方程可能只有局部解或存在多解(我们称这样的系统为非适定系统，相应的最优控制问题为非适定最优控制问题)，以及适定的非线性发展方程最优控制问题的庞特里雅金最大值原理；我们研究了phase-field系统的时间最优控制问题以及Boussinesq系统的局部内可控性。

In this regard Xunzi's thought is at least six centuries ahead of Porphyry's.

荀子提出了一个名称分类体系，其中涉及名称和事物之间的种属包含关系，其思想领先於古罗马的波菲利至少六个多世纪，但不如后者的理论系统、完善和深入；他强调了名称的社会性、约定性和强制性，论述了名称的「约定俗成」本质，以及「约定俗成」的制名过程，这涉及到语言的社会分工；他论及了名称的认知功能和交际功能，但更为关注名称的社会政治功能和道德教化功能；他讨论了制名的本体论根据和认识论根据：命名对象本身的同异，以及人的认识器官对这种同异的感知和认识，是制定不同名称去指涉这些对象的基础；并讨论了制名和正名的一些关键性环节，以及使用名称的三种基本谬误，最后探讨了名称在辩说体系中的地位和作用。

To evaluate this theory, investigators collected anxiety-level data from 71 normal primipara mothers via questionnaires throughout their pregnancies. When the 72 children were aged eight or nine years, their mothers, a teacher, and an impartial observer completed questionnaires measuring each child's attention and hyperactivity, acting-out behavior, and anxiety level.

为了评估这个理论，研究人员针对71位初次怀孕的母亲，收集这些孕妇在整个怀孕过程中的焦虑相关资料；当72位儿童成长至8或是9岁时，他们的母亲、一位老师以及一位公正的观察者完成有关评估每位儿童的注意力以及过动性、外在的行为以及焦虑程度的调查。
