查询词典 spheres

SEM observation of the earliest skeletal fossils from the late Sinian Dengying Formation in southern Shaanxi, China indicates that the tube wall of Sinotubulites levis is encrusted by phosphate spherical and filamentous structure, possibly reflecting microbially mediated phosphatization of tube wall. Three preservational microfabrics detected, namely mat-like structure formed by intertwining of rigid filaments, densely packed spheres with a distinctive framboidal external surface and hollow centers and tightly packed spherical bodies with extremely smooth external surface, may refer to different types of mineralized cyanopytes.

陕南晚震旦世高家山生物群中骨骼化石的电镜扫描显示，Sinotubulites levis壳壁中具有丰富的磷酸盐化球状和丝状体，可分为3种不同类型的微生物组构：1由相互缠绕的丝状体所组成的藻席状组构；2由外表面成莓球状，内部中空的球状体紧密堆叠所形成的组构类型；3由表面极为光滑的球状体堆叠所形成的组构。

In particular, the New Democracy of physical culture contained three spheres-national, scientific and mass.

I am going to take all who desire to be taken into spheres of knowing that will transcend the pittance of your senses.

我会带上所有渴望真知的人，进入那完全超越你们狭小感觉范围的界域。

A new method is advanced to calibrate the sensitivity and zero point in multi-passage sphere diameter gauge with two standard spheres.

提出了用两只标准球同时标定具有多个测量通道的球径测量仪各通道的灵敏度和零点的一种新方法，避免了各通道单独标定的繁杂过程。

The results show that a separate dunk is observed near the stagnation point of the second sphere on the distance of spheres L≤2.5D because of the influence of reverse pressure gradient.

结果表明：当L≤2.5D时，由于逆压梯度的影响，在第二个圆球滞止点附近捕捉到附体分离泡；由于第二个与第三个圆球的置入，展向压力梯度诱发第一个圆球背风面流动的展向输运，且随着圆球间距的增加流场的展向输运趋势减小，但涡的强度增大；第二个圆球与第三个圆球背风面流动没有明显的展向输运；湍动能的增量与圆球间距近似成平方规律。

This method was used to measure the interaction potential of a pair of 1μm diameter polystyrene spheres.

对1 μm直径的聚苯乙烯球悬浮液中两个小球之间的静电相互作用势进行了实验研究。

By spraying and coating the potassium carbonate solution onto the surface of glass spheres, the layering growth mechanism of granulating process was studied in fluidized bed.

通过在流化床中将碳酸钾溶液雾化后喷涂在处于流化状态的玻璃珠上，研究了流化床造粒过程的层式生长机理。

The dissolubility of PPLA in water was (2.16～4.32)×10－2 mg·mL－1 according to eye judgment. The critical micelle concentration was 2.16×10－2 mg·mL－1 obtained from a fluorospectrophotometer. The self-assembled aggregates of PPLA in water were nanoscale spheres observed by a transmission electron microscope. The particle size and zeta potential tests by dynamic light scattering revealed that during preparation, the ratio of hydrophilicity/hydrophobicity, the aqueous medium and the pH had great influences; while dilution, freezing and pH change to basic condition had no effect after preparation, but pH change to acidic condition made the nanoparticles precipitate.

目测法得到其溶解度为(2.16～4.32)×10－2 mg·mL－1；荧光法得到聚合物的临界胶束浓度为1.12×10－3 mg·mL－1；透射电子显微镜观察显示该聚合物在水中的自组装聚集体为纳米级球形；动态激光光散射测试微球的粒径和Zeta电位发现，在微球的制备过程中，聚合物的亲/疏水性比例、水相介质及水溶液的pH值对它影响显著；而制备后，稀释和冷冻对它无显著影响，改变微球的环境pH值至酸性，出现聚集，至碱性无影响。

In particular, the researchers found that structures which would have remained thin and film-like in normal spider silk (which forms in a watery environment) thickened into tiny fibres and spheres in propanol.
