A new flux expansion nodal method was developed to solve three-dimensional multigroup neutron diffusion equations in hexagonal-z geometry. The method expands the intranodal homogeneous flux distributions in analytic basis functions for each energy group.

提出了一种在三维六角形几何节块内数值求解多群中子扩散方程的节块法，该方法把节块内各群中子通量分布用解析基函数近似展开。

Chapter 3 emphasizes on the case that the considered systems contain not only impulse but also time delay. We mainly investigate impulsive parabolic systems with time delay and neutral impulsive parabolic systems. Section 3.1 discusses the oscillation of impulsive parabolic systems with time delay under Robin boundary condition and obtains some useful criteria via first order impulsive differential inequalities with time delay. Section 3.2 studies the oscillation of neutral impulsive parabolic systems under Neumann boundary condition and Robin boundary condition, respectively, and obtains some sufficient conditions for oscillation and strong oscillation via first order neutral impulsive differential inequalities.

第三章针对于"脉冲"与"时滞"共存的复杂情形，仍采用反证法讨论了含时滞的脉冲偏微分系统的振动理论，具体研究了脉冲时滞抛物系统和中立型脉冲时滞抛物系统。3.1节考虑了脉冲时滞抛物系统的振动理论，借助于一阶脉冲时滞微分不等式的解的性质，得到了满足Robin边界条件的脉冲时滞抛物系统的若干振动准则；3.2节考虑了中立型脉冲时滞抛物系统的振动理论，借助于一阶中立型脉冲时滞微分不等式的解的性质，分别给出了满足Neumann边界条件和Robin边界条件的中立型脉冲时滞抛物系统的若干振动和强振动准则。

Based on the equations, a new method for the geometrical design of hypoid gears is presented.

在这组方程的基础上，提出了一种几何设计的新方法，以大轮的节锥角和节圆半径以及小轮的螺旋角这三个参数为自由变量，以准双曲面齿轮副的偏置角为中间变量，用数值求解方法能够非常方便可靠地确定节锥的参数。

In this part,chpater 2 is about how to overcome the problem of uncomplete information.

在这部分中，第二章研究信息不足的制度克服；第三章研究信息不对称的制度克服；第四章研究信息错误的制度克服；第五章主要研究制度如何降低信息成本，该内容有相当部分散见于第二、三、四章之中，之所以还要对其单列一章作专门的论述，是因为信息成本的降低是信息失灵问题是否得到克服的最为重要的指标，信息成本的充分降低表明决策主体的信息充分、准确且对称分布性，这有助于减少决策主体的支出，增加其决策利益，因此需要对信息成本降低的障碍及路径等问题展开研究；第六章研究公权信息的公开问题，该章主要对公权信息的强制性披露问题进行研究，它本质上是一种克服信息不对称的制度，所以把它列入第三章第一节第一部分有关强制性信息披露制度之中也并无不可，但由于公权信息的公开涉及到公权层面，与有关对私权主体的强制性信息披露制度相比具有较多的特殊性，所以，本文对其专列一章予以阐述。

During the last three decades, several models have been proposed to explain the formation of somites, including the clock and wavefront model, the reaction-diffusion type model, clock and induction model, clock and trail model etc. Although some of them are satisfactory in the different aspects of somitogenesis, no one can explain the formation and regulation of somites perfectly.

近三十年来，研究者们就体节的发生和发育提出了多种解释模型，这包括时钟波阵面模型，反应扩散模型，时钟诱导模型，时钟痕迹模型等，虽然这些模型能从不同角度不同程度来解释动物体节发生和发育的不同现象，但无一能够解释体节发生和发育的全部。

In the final quarter, Kobe Bryant start shooting really hot from 3-point line, he was 4 of 6 from 3-point line in fourth quarter, and he made a 3+1 play, but unlucky he missed his only free throw of the game.

湖人带著落后12分的劣势打第四节，虽然老大三分线外开始了狂飙，三分球整个第四节6投4中，还有一次3+1，可是老大投失了这个他全场唯一一次的罚球。

Three times a year all your males shall appear before Jehovah your God in the place which He will choose: at the Feast of Unleavened Bread, at the Feast of Weeks, and at the Feast of Tabernacles.

16：16 你一切的男丁，要在除酵节、七七节、住棚节，一年三次，在耶和华你神所选择的地方朝见祂。

Three times in a year shall all of your males appear before the LORD your God in the place which he shall choose; in the feast of unleavened bread, and in the feast of weeks, and in the feast of tabernacles: and they shall not appear before the LORD empty

016 你一切的男丁要在除酵节、七七节、住棚节，一年三次，在耶和华─你神所选择的地方朝见他，却不可空手朝见。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
