Each host molecule 1 crystallizes with two CH3OH and two H2O guest solvates locating in the large rhombic channels formed by the parallel arrangements of 1 with significant aromatic stacking interactions.

每个主体分子1同时与2个甲醇和2个水溶剂客体分子结晶，主体分子之间存在显著的芳环堆积作用，在晶胞中呈平行排列并形成大的菱形通道，客体分子位于此通道中。

It was found that there were dense dot shaped internal oxidations and a large amount of spherical crystal nets.

这说明结晶器的冷却能力差，在固相和液相共存区的包晶线附近通过的时间过长，导致在二冷区夹辊作用下沿枝晶产生了裂纹。

These two elements precipitate into otoliths crystal lattice or interstitial to substitute for calcium (Ca2+) in vaterite or aragonite. The precipitation of otoliths is controlled not only by biological regulatory, but also influenced by environmental factors, such as: element concentration, salinity, temperature of ambient water, food intake, etc.

耳石结晶沉淀的整个过程不仅受生物的调控作用，而且还受到外界环境，如水体元素浓度、盐度、温度等因素的影响，因此耳石中某种元素的浓度与其在水体中的浓度之比与鱼类所生存的环境之间具有一定的响应关系。

By applying ultrasonic wave to different PP/nucleators system, crystalline structures of PP are changed.

静态超声作用使PP及PP/成核剂体系的结晶行为发生了显著变化。

Chlorine atoms may play a space-filling role in the crystallization process.

这可能是由于氯原子在结晶过程中起到了一个空间填充的作用。

Strain rate hardening due to GBS suppressed the DRX softening and local necking so that the uniform and total elongations tended to increase at the temperatures of 400℃ and 500℃.

而晶界滑移所导致的应变速率硬化效果，则会降低动态再结晶对於材料的软化作用，进而增加AZ31B镁合金在400~500℃的均匀延伸率，并因抑制颈缩现象的进一步发生，而增加高温延性。

We found that hexanoic acid and octanoic acid are insufficiently soluble (with solubilities of 9.68 and 0.68 mg ml21, respectively, in water) to produce any growth modification in L-asparagine monohydrate crystallization.

我们发现，己酸和辛酸在水中不能充分溶解（溶解度分别为9.68和0.68mg/ml，水溶液中），这一特性使它们对L -天冬酰胺单水合物结晶的生长起修饰作用。

The results show that the plasticity zone and dynamically quiescent layer become fine equiaxed recrystallisation under the thermo-mechanical effect, the grains in the heat-affected zone grow up because of the effect of friction heat. When the rotation speed is 2 500 r/min and the welding time is 12 s, good joint is achieved, and the tensile shear strength of the joint reaches 9.24 kN. The tensile shear strength of spot increases with increasing tool rotation speed, with increasing welding time, the strength increases first, while then reduces. The microhardness of plasticity zone is high, but is slightly lower than that of the base metal, the minimum value of microhardness is in the heat affected zone. When the energy input of joint is high, the fracture type of spot is mode Ⅰ, and the tensile shear strength is high; on the contrary, when the energy input of joint is less the fracture type of spot is mode Ⅱ, and the strength is low.

结果表明：塑性区和动态静止层的晶粒在热和力作用下发生动态再结晶形成细小的等轴晶，热影响区的晶粒在摩擦热作用下长大变粗；搅拌头旋转速度为2 500 r/min，焊接时间为12 s时，可以获得力学性能较好的焊点，焊点的剪切强度达到9.24 kN；焊点的剪切强度随搅拌头旋转速度的增大而增大，随焊接时间的延长先增大后减小；塑性区的显微硬度较高，但略小于母材，接头显微硬度的最小值分布在热影响区；焊点热输入量较多时，接头为Ⅰ型断裂，焊点的剪切强度较高；焊点热输入量较少时，接头为Ⅱ型断裂，焊点的强度较低。
