The results showed that the patterns of Sheldon size spectra were similar at all stations in transects A and B.

横跨台湾海峡沿岸及浅滩外斜上升流的A和B两断面Sheldon粒径谱类型相近，正态化谱图的斜率r的范围从-0.79到-0.65，在明显高于寡营养海域的水平上波动。

Size 1/2"(15mm) dual connection, solder or male IPS x 3/4"(20mm) hose thread connection, angle pattern

Further, a part of a side wall on both right end and left end of the lower half in quite an area at circumference of maximum coiling diameter of the magnetic tape wound around the takeup hubs is cut.

另外，把被设在上述下半部的左右两端上的侧壁的与被卷绕在上述卷芯上的磁带最大卷径外周相当的一定范围的部分切成缺口。

72"Wide sheet line consisting of the following: extruder, 30:1 L/D ratio, electrically heated, air cooled. 300 hp DC drive Control panel. hydraulic screen changer with power pack, 60"wide sheet dies with external deckles.

72&宽板材生产线包括以下设备：挤塑机(长径比30：1，电热，风冷)，300马力直流驱动控制面板，自带动力单元的液压换网器，60&宽板材外堵式模头

E The fractal and spherical particles exist favorably in the coarse fraction, while in the fine mode (0μm) are floccules formed by flocking fine particles together, containing crustal elements and mainly being silicates and aluminosilicates. f The content of Al, Si, Fe in TSP samples is higher than in PM〓, indicating an enrichment of these elements in coarse mode. g Compared with non-dust particles, the dust particles are more homogeneous in terms of morphology, particle size and composition. h Particles with irregular shape and well-distributed size dominate in dust samples, containing crustal elements such as Mg, Al, Si, Ca, Fe et al.

细粒中除小圆球外，大多为细小颗粒聚结在一起的不规则块状颗粒，主要含地壳元素，可能是硅酸盐和铝硅酸盐。fMg、Al、Si、Fe在PM〓中的含量较相应的TSP中的低，可见这些元素主要存在于较粗颗粒中。g沙尘期气溶胶粒子的形貌较非沙尘期单一、均匀，非沙尘气溶胶粒子的形貌、组分较沙尘期复杂。h沙尘期样品中，粒径均匀、形状不规则的颗粒最多，这些颗粒主要含地壳元素Mg、Al、Si、Ca和Fe等，是典型的由源区传输过来的沙尘粒子，但其高硫含量表明在青岛特殊的地理环境下，在粒子表面发生了硫的均相和非均相反应。

All sizes have a male straight-pipe threaded for locknut.

所有通径都有直线管道外螺纹用于防松螺母。

The results indicate that CEPNPs are core-shell nanostructure, the particles size is 75 nm on an average; CEPNPs magnetic fluid looks black and viscous and stable, and the viscosity of CEPNPs magnetic fluid decreases with increasing shear rate without magnetic field and increases with the applied magnetic field.

结果表明：制备的CEPNPs具有壳／内核包覆结构，平均粒径在75nm左右；以其制备的磁流体外观呈黑色粘稠状，稳定性好，在无磁场条件下磁流体粘度随转子转速的增大而减小，有外磁场时，磁流体粘度随磁场强度增大而增大。

Beautiful landscapes are one attraction of Hong Kong trails. Safety is another. Despite a series of recent muggings and robberies on some of Hong Kong's hiking tails, mainland hikers still say Hong Kong is safer."Shenzhen hikers were robbed at times," Woo says. When we camp, we have to get one to two men to guard our camp throughout the night.

行山径上美丽的海岸风光故固然吸引，安全亦是很重要的，近日香港虽然接二连三发生郊野公园行劫案，内地行山人士仍然觉得香港是比较安全，宇宙公民说：「深圳经常出现行山人士遇劫事件，所以当我们在深圳露营时，我们必须在晚上留下两个男生在营外守护，整夜不睡」。

What to do in a place like this- You can swim, surf, dive, sail, golf, play ball, ride, explore, bargain hunt, sight see, explore, or drive a dune buggy for 100 miles in any direction, take a jeep up a steep mountain trail.

怎样做一个这样的地方--你可以游泳、冲浪、潜水、风帆、高尔夫、打球、骑、探索、亨特讨价还价，看到的景象，探索，或径为100英里的沙丘派上外太空任何方向一辆吉普车采取了陡峭山步道。

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。
