紧密度

We now have modern, precise instruments to evaluate this event, and because the site abuts a continent, we will be able to obtain dense spatial sampling of the changes it caused.

我们现在有最新的精密仪器来以测评这一事件，因为位置紧靠大陆，我们将能够获得其造成变化的高密度立体空间样品。

The body coat is a thick mass of small, tight, crisp curls, lying close to the skin, resilient, water resistant, and of sufficient density to provide protection against weather, water and punishing cover.

身躯的被毛浓厚，由大量小、紧、脆的卷毛组成，紧贴皮肤，有弹性，能防水，且有足够的密度以抵御恶劣的天气和雨水。

Fifteen one-layered fabrics with different texture, density of fabric and fiber disposition were designed and woven before the designation of medical barrier fabrics.

在设计医用屏蔽织物之前，设计与试织了十五种具有不同织物组织、经纬密度和原料配置的单层织物，通过对它们进行性能测试和分析，探讨织物组织结构对其拒液性和透湿性的影响，得出了织物组织、纤维细度、织物紧度、织物达到高密的方法等几个因素影响这两种性能的主要规律，为医用屏蔽织物的开发奠定了理论基础。

The band structures and the band gaps of some single-walled carbon nanotubes were calculated and their ...

但是，一方面，那些结论大多数是对孤立的单壁碳纳米管而言的，而且跟实验没有很好的吻合；另一方面，采用的方法大多数是紧束缚计算和基于局域密度近似的第一性原理计算。

When the pulverized material has been properly sized, mixed with the additive in the amount determined by testing, laid and compacted to the required density, surfaced with a chip seal coat, thin hot mix overlay or other light surfacing, a long lasting, low cost pavement can be constructed with a minimum of new material.

只有当被压碎的材料已制成合适的大小，混合了经测试确定的适量添加剂，铺设并压紧至要求的密度，再用一层碎片封闭层、热混薄覆盖层或其它轻质的材料铺平表面，经时效处理后，方可达到以用量最少的新材料构筑出低成本路面的目标。

Rotor Type Sand Mixer Model AMW28 is a massive and high efficient machine with 80-100 t/h productivity (wet pressure strength 10N/cm2, compatibility 35%, density 0.9-1.0g/m3 and circle time 90 s).

该机是我厂设计生产的大型高效率转子式混砂设备，生产率80-100 t/h（在湿压强度为10N/cm2，紧实率35%，松砂密度为0.9-1.0g/m3，循环时间为90秒/次的条件下）。

When fitted property, the precisely engineered Fiberglass/Dyneema/Carbon Fiber composite shell and energy absorbing dual-density EPS liner greatly reduce the possibility of head injuries in the event of an accident. To keep you focused on what's ahead of you the Airframe is fitted with Icons new Proshield. Not only is the Preshield available in a variety of tinted styles with side plates for more graphic real estate, it features the prolock shield lock system to keep you shield locked down.

玻璃纤维/迪尼玛/碳纤维复合材料壳体能量吸收高密度冲击，大大降低头部受伤可能性，最新高明度耐冲击材料镜片让您专注于在您的前方物体。prolock镜片系统，即使在时速150英里每小时都可以保持你的镜片紧锁。

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。
