致密的

The observations reveal warm (320 K) dust in a structure 2.1 parsec thick and 3.4 parsec in diameter, surrounding a smaller hot structure.

观测显示，在NGC 1068中心的尘埃圆环面原来是一个比较热的（320 K）的致密结构，直径约几个光年，它阻断了我们的视线，使我们无法看到该星系最里面的活动区域。

With the reduction of SOM content and the elevation of contamination concentration, the difference between PHE and PYE decreases gradually, while B［a］PYE exhibits a significant difference from them. This could be attributed to the high lipophilicity and large molecular size of B［a］PYE, which make the molecule of B［a］PYE to be more easier to be held in the nanopores of clay and the dense region of SOM.

不同多环芳烃SPMD辅助解吸率差别很大，随着土壤有机质含量的降低，以及污染物浓度的提高，菲和芘的解吸差异逐渐缩小，而苯并［a］芘与上述2种多环芳烃的差异很大，主要是由于苯并［a］芘具有高度亲脂性，并且分子较大，造成其容易滞留在粘土的微孔及有机质的致密结构中。

Water and nutrients are only transported in the outermost youngest wood, termed the SAPWOOD. The nonfunctional compacted wood of previous seasons ' growth is called the HEARTWOOD and it is this that is important commercially.

水分和养料的运输仅限于发生在初生木材的最外围，即边材；前一季度生长的致密无功能的木材称为心材，此为重要的商业用料。

6Combining with several SEM pictures of different samples, cement-soilmicrostructure characteristics are described. Test results show that the cement-soil,whose stock-still time is longer, is a little worse of its strength than the one withoutstock-still time, because of its discontinuous microstructure and some micro-cracksbetween inter-particles.

6结合不同样品的SEM图片，描述了不同样品的微结构特征，试验结果表明，静置时间较长的水泥土由于微结构的不太致密、颗粒间存在较多的微裂缝，故其强度性能稍差。

Results? 6 cases in X-ray film revealed round or oval stones in areatus distribution in the areas of renal papillae and medulla. 3 cases of IVP revealed cystic or hair-brushed dilation. 5cases in B-ultrasound revealed little anechoic area and strong echo light spot in radial distribution with acoustic shadow. Unenhanced CT of 6 cases revealed spotted or areatus stones surrounding minor renal calices with collecting tube system dilation and enhanced CT showed artifacts of stones magnification because of the collection of contrast medium around the stones. Conclusion?

结果 X线平片检查6例，表现为肾乳头、髓质区见簇状排列的圆形、椭圆形致密影；IVP检查3例，显示肾集合管囊状、刷子状扩张；B超检查5例见肾髓质内呈放射状分布的小无回声区和强回声光点，其后方伴有声影；CT检查6例，平扫呈环绕肾小盏分布的点状或簇状钙化灶，集合管囊状扩张，增强后因钙化周围的集合管内造影剂聚集，造成钙化影增大的假象。

AFM images revealed that as the sputtering time was prolonged, the film thickness increased, the film became compacter, and the specific area of the film also increased, thus, the release rate of silver ions increased, which led to improved antibacterial properties. EDX test results indicated that increase in film thickness led to increase in silver weight percentage per unit surface, causing improved antibacterial properties. Moreover, when the film thickness was 1 nm, the inhibition percentage of Staphylococcus aureus and Escherichia coli were 100%.

结果表明：随着薄膜厚度的增大，样品抗菌性能提高；溅射时间延长，薄膜厚度增大，膜层的致密性改善，单位面积上的银含量增加，膜层表面积增大，银离子释放几率增大，是提高抗菌性能的主要原因；当纳米结构银薄膜厚度为1 nm时，对大肠杆菌和金黄色葡萄球菌的抑菌率均达到100%。

Sintering behavior of diphasic aluminosilicate gel and microstructure of ceramics were studied over a range of chemical composition (Al 2O 3/SiO 2 ratio).

对具有不同Al2O3／SiO2比的双相铝硅凝胶的烧结行为及陶瓷材料的显微结构进行了研究。结果表明，少量液相的存在对先驱粉末的致密化速率和材料显微结构有显著的影响。

The pore distribution in the direction of coating thickness was self-existent and could not join to intercommunicating pore.The pore diameter was very tiny so that it could prevent hydrotropic solution entering into the pore.

机械镀锌的形层过程既没有热镀锌那样的高温冶金反应，也没有电镀锌那样的电沉积效应，镀层是常温常压下利用化学吸附沉积和机械碰撞使金属锌粉在工件表面镶嵌堆积而成[1]，所以人们认为机械镀锌镀层的致密性要低于电镀和热镀锌镀层，但机械镀锌镀层又表现出良好的耐腐蚀性能。

In comparison to the process simply using a Hall ion source for the IBAD, the coating has a more compact and uniform structure and a better property in polishing. After surface modification, the surface roughness of the substrate is reduced to 0.635 nm which is the same as that of the S-SiC substrate, also the surface reflectance is obviously enhanced to that of the fine polished zerodur glass.

测试结果表明：与单纯霍尔离子源辅助方法相比，该工艺方法制备的Si改性涂层生长得更加致密、均匀，抛光特性良好；改性抛光后表面粗糙度降低到0.635 nm，达到了S-SiC基底的水平；改性后RB-SiC基底的反射率明显提高，达到了抛光良好的微晶玻璃的水平。

The smooth degree of soil surface will be influenced by keeping the loess's cubage unchanged and changing the loessial dense degree by loessial weight, which can influence polarized reflection.

在保持土壤体积不变的情况下，通过改变土壤的质量来改变土壤的致密程度，进而改变土壤表面的光滑程度也可以影响土壤的偏振反射。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
