The crystal belongs to triclinic, space group P-1 with α=0.775 1(2) nm, b=0.837 7(2) nm, c=1.003 7(2) nm,α=75.57(3),β=83.05(3),γ=86.08(3), D=1.296 g/cm^3, Z=2, F(000)=256,μ=0.095 mm^(-1), and the final deviation factor R=0.0545 and wR=0.146 0. X-ray analysis reveals that molecules are linked by intermolecular O-H…O hydrogen bonds formed between the adjacent molecules.

具体测定结果如下：该晶体属于三料晶系，P-1空间群，α=0.7751 (2) nm， b=0.8377 (2) nm， c=1.0037 (2) nm，α=75.57 (3)，β=83.05 (3)，γ=86.08 (3)， D=1.296 g/立方公分，Z=2， F(000)=256，μ=0.095 mm^(-1)，最终偏差因子分别为R=0.0545，wR=0.1460.X-射线衍射分析表明，分子之间通过相邻分子间形成的O-H…O氢键相连。

Due to their applications in magnetic, optical, electronic and catalyst, polynuclear lanthanide clusters are of importance. In this part, a series of nanowheel-shaped nonanuclear lanthanide clusters,〓〓(Ln=Sm~Tm; BA=benzoylacetone), were prepared and characterized. Each complex can exist in three phases, i. e., cubic, tetragonal and triclinic.

The influences of EBRT and inlet concentration on the removal efficiency of trimethylamine were investigated and discussed.

该系统采用了棕纤维复合生物填料，在温度为25~35℃、空床停留时间20.0s、TMA进气浓度为536~895mg/立方公尺、臭气浓度为9724~13431倍时，系统对TMA、臭气的平均去除率分别达91.98%、98.70%。

The energy erupted by the volcano is even more powerful than that of the explosion caused by trinitrotoluene of 100 million ton or 150 million ton or dozens of hydrogen bombs since the volcano erupted about 40 cubic km magma rock.

它爆发的能量比1亿或1.5亿吨烈性梯恩梯的能量还要大，因为它喷射出了约40 立方公里的岩石。

计算结果表明，在不考虑表面能的情况下，当量子点高宽比增加时，弛豫度上升，并且发现平顶金字塔形量子点最先达到稳定；岛间距增大时，量子点内应变能下降，其中立方体形量子点应变能下降最快。

The results indicate that when ignoring the surface energy, the relaxation degree increases with the increase of the aspect ratio regardless of the shape, among which the truncated pyramid quantum dots tend to become steady earlier than others. With the increase of the inter-island distance, the strain energy in the dots decreases, especially in the cubic dots.
