These changes make it clear that the era of developing the county economy advents.

这就表明中国经济在向城市经济侧重近20年后，正进入向县域经济侧重的转换阶段，宏观经济部署开始走出&重城轻乡&的非均衡阶段，宏观经济政策呈现出向县域侧重的明确的方向性变化，中国县域经济大发展时代已经到来。

In as-cast microstructures, SG modification can refine austenites and inhibit their orientational arrangement, reduce and refine the intercrystalline carbides; in heat-treatment process, SG modification can either shorten the holding time or lower the holding temperature.

SG 变质处理能有效地抑制铸态组织中柱状晶的生长，细化奥氏体组织并降低其方向性，减少晶间碳化物数量并使之细化；对热处理组织，SG 变质处理可以加速碳化物溶解，缩短水韧处理的保温时间或降低水韧处理的温度。

Cees Hamelink said, at Seminar on Communication Development and the International Programme for the Development on communication in 1984, that as social scientists we are always better at criticizing bad models than at presenting new model. Most of us written extensively and critically about How lerner and Schramm and Rogers have inadequately dealt with all these things, and they have admitted their mistakes themselves, but none of us has really come forward with, a new and better model.

在如何改进大众传播促进乡村发展的功能这一核心问题方面，本文提出了：1）加强&小媒介&的作用；2）充分利用乡村基层组织正式团体渠道多级传播作用；3）注意挖掘和激发乡村&精英分子&的&言传身教&作用；4）提高媒介工作者素质，在知识化、年轻化、专业化方向努力；5）改进领导艺术，适应调整媒介管理体制等方向性建议。

Some activity, like mass ejections, are directional. Earth may not be in the path of a particular ejection so all activity does not affect Earth.

有些活动，像是日冕物质喷射是具有方向性的，地球也许并不在其特定的喷射途径中，所以并不是所有的太阳活动都会影响地球。

A power source is applied to the structure to control the directionality of the plasma formed by exciting the power isolation of the etchant gas.

One simplified hypothesis is that, when the growth cone detected the directional signal, actin will polymerize asymmetrically in the growth cone, so that the filopodia and lamelipodia will extend preferentially to one side, microtubule will further follow and stabilize this growing direction.

一种假说认为，当轴突生长锥探测到方向性的信号时，生长锥内的 actin成分发生不对称聚合，filopodia及lamelipodia向一侧优先延伸，进而轴突内微管也朝同侧延伸，使生长方向进一步稳定下来。

Considering that fz6-related genes are consered between species, the same self-organizing system likely "applies to all mammals, and also to bird feathers and fish and reptile scale orientation," Nathans says.

考虑到fz6相关基因在种群中有保留，Nathans说，同样的自体组织系统可能&适用于所有的哺乳动物，也包括鸟类羽毛，鱼雷和爬行类鳞片的方向性。&

While performing the seismic modelling experiment , it needs to have tens to hundreds of kilohertz and well distributed orientation dependent narrow pulse acoustic wave as simulation source .

由上述理论和实验的研究，研制出了具有一定灵敏度，方向性较均匀的窄脉冲压电换能器，初步满足了地震模型实验的要求。
