在传播中

The general publicincreasingly focuses their attention on environment issues and the mass media plays acritical role in educating and raising awareness.

而作为信息流通平台的大众传媒也毫无疑问的在传播环境知识、环保理念中发挥着巨大的影响力，推动了环保事业的发展。

We all know that sound can travel through air.

我们都知道声能在空气中传播。

However, direct evidence of alimentary transmission and infection in mammals is lacking.

然而， 在哺乳动物中缺乏饮食传播和感染的直接证据。

For example,the spiral arrangement of scale－bract complexes on ovule－bearing pine cones,where the female reproductive organs of conifers are located,is important to the production of airflow patterns that spiral over the cones surfaces,thereby passing airborne pollenfrom one scale to the next.

例如，带有胚珠的松球的鳞苞综合体的螺旋状安排，亦即松柏目植物雌性殖器官的所在位置，对于气流模式的形成与产生殊为重要，而这些气流模式在松球的表现盘旋上升，从而把在空气中飞行的花粉从一个鳞苞传播至下一个鳞苞。

Because of the light weight, carbon nanotubes can easily spread in the air and human lungs leading to toxicity.

一方面，碳纳米管可能在生物医药领域有潜在的应用，另一方面，由于碳纳米管质量轻，容易在空气中传播，很容易经呼吸道进入人体并造成毒性。

In this paper, an equation descriping Proca light traveling in gravitional field is derived.

本文在导出Proca光线在引力场中的传播方程后，以球对称引力场以及平面引力波分别作为静态和动态引力场的例子，计算了有质量光子对应的光线偏折与频移。

He not only made excellent consideration and communication between Greek philosophy and Bible,but also played an important role in the dissemination of Neo-platonism of late period of Greece and the Christian thought of Greece to Rome and the West,this had an important significance to the Christian thought of the Middle Ages.

他不仅在希腊哲学和《圣经》之间进行了卓越的思考和会通，而且在晚期希腊新柏拉图主义和希腊基督教思想向罗马和西方的传播中发挥了主要作用，这对中世纪基督教思想意义重大。

For some time now, National By-products has been a user of SWEPCO 80/90 gear lube in the transmission, differentials and wheel hubs on our hauling vehicles.

最近， 国有副产品中在传播使用SWEPCO80/90齿轮润滑油，其使用在我们拖拉机的差动齿轮和轮毂。

Cultural traditions,social and political contexts,and economic environments in specific counties can affect PR practices.As noted earlier in the chapter,the mass media and the written word are important vehicles for information dissemination in many industrialized countries.In developing countries,however,the best way to communicate might be through the gong man,the town crier,the market square,or the chief's courts.

文化传统、社会和政治环境和经济环境，在特定的县能够影响公关行为就像之前提到的一章，大众传媒和文字是重要的信息传播的许多工业化国家里在发展中国家，但是，最好的方式来传达可能通过贡人、松子、市场、或法院的。

Combined with numerical simulation, characteristics of wave propagation on a slope and a platform and wave forms are discussed, and the maximum wave pressure, acting position and the maximum wave forces are systematically analyzed. Compar...更多ison of wave forces on a vertical wall with different slopes is made, and a conversion relation is given.

本文在水槽中进行平底、1：5、1：10、1：15、1：20、1：25建筑物前几种不同坡度的规则波模型试验，与数值计算相结合，讨论了波浪在斜坡及平台上传播的特性和波浪形态，对直墙上最大波压强及其作用位置以及最大总压力进行了系统的分析，进行了不同斜坡直墙波浪力的比较，给出了它们之间的转化关系。

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。
