During the calculation the results got by quintic spline kernel was the best so it was chosen as the proper kernel for the SPH simulation. By comparison of the simulation results got by SPH and finite volume method, it was proved that the buffer cells method proposed in the SPH simulation to implement the Dirichlet boundary conditions was accurate, and this is of great importance for the simulation of flows pass a pipe. At last, the SPH method was improved to simulate the liquid-solid two phase flows and the results show that this method was appropriate for the simulation of flows containing viscous fluid and macroscopic solid components. Now the two methods are both able to predict the continuum flows and rarefied flows severally, but the hybrid program still has some aspects to be improved.

首先用标准算例验证了SPH方法的理论模型和计算程序的准确性；通过比较确定选用五次样条核作为计算低雷诺数下的粘性连续流动时的核函数；采用SPH方法和有限体积法分别对同一管道流动进行了对比计算，证明了本文提出的边界缓冲区方法在实现SPH方法中的流体边界条件时的有效性，解决了SPH方法模拟管道流动时的一个关键问题；巧妙地使用SPH方法对化工分离流动中常见的固液两相流及固液耦合作用进行了模拟尝试，获得了较好的结果；在跨尺度计算方面，目前两个子程序已经能够分别模拟连续的和稀薄的二维管流问题，二者的耦合计算程序还处于调试和优化阶段，各个参数对于计算精度和计算速度的影响规律仍在探索中。

Taking distributed control system used by 220t/h circulation fluid bed boiler and 25MW double extraction condensing turbine as examples,aiming at the problems exiting in distributed control system,from the aspects of improving safety,generality,flexibility,control performance,integrative management ability,being easy to use and maintenance,adopts a serial of new ways and strategies,makes it being into the new control system which other control systems can't compare with.

以220 t/h 循环流化床锅炉及25 MW双抽凝汽式机组所使用的分散控制系统为例，针对分散控制系统在应用中所存在的问题，对该控制系统在提高安全可靠性、通用灵活性、最优控制性能、综合管理能力以及方便使用与维护等方面，采取了一系列新的方法与策略，使之成为其他控制系统无法比拟的新一代控制系统。

Casting the spell will take a reasonable amount of time, to prevent it from being used as an escape mechanism from combat.

玩家将能使用"锅炉之石"来回到玩家自己在旅馆的"居所"使用它需要一定的时间，以防被用与在战斗中轻易逃脱

Simulation results show that mean error of this algorithm is generally below 0.05 when 200 training symbols are used.

模拟结果表明，在使用约200个训练符号时，相关矩阵中每个元素的平均估计误差在0.05以下，而使用更多的训练符号时，估计精度将会进一步提高。

A letter of 1573 written by Gabriel Harvey contains the first recorded use of good-bye :"To requite your gallonde of godbwyes, I regive you a pottle of howdyes," recalling another contraction that is still used.

在加布里埃尔·哈维1573年写的一封信中就有使用good-bye 的第一次记载："为回赠您千千个再会，我致以万万个问候。"出现了现在仍在使用的另一个缩略语

Governmental procurement that introduces market competitive system into the repartition and use of finance capital, is an important means to manage public payment.

政府采购将市场竞争机制引入到财政资金的分配和使用中来，通过公开招标采购，从而控制政府支出，保证采购资金的节约使用，实际上是在市场经济条件下对公共支出管理的一种重要手段。在我国，政府采购的观念才刚刚引入，对政府采购制度的研究更是十分薄弱。
