角峰

利用水溶性聚乙二醇与硅物种在聚合过程中的相对亲水-疏水性差异控制合成中的相分离，成功地合成了具有XRD小角衍射峰的无序介孔材料。

The synthesis is based on the interaction between hydrophilic polyethylene glycol and hydrophobic silica species , which leads to disordered mesoporous silicas that show diffraction peaks in the low angle XRD pattern .

结果：在跖趾关节运动受到约束后，人体其它关节角位移峰-峰值和角速度峰-峰值均有明显变化。

Result : The apparent differences can be seen between the peak angular displacements and velocities of each joint for subjects with and without MP joints constraint .

经一次扫描得到的维生素B2和B6的可变角同步谱峰位置与它们对应的常规光谱中激发一发射峰位置一致。

The locations of variable-angle synchronous fluorescence peaks for vitamin B_2 and B_6 coincide with those of excitation and emission peaks in routine spectra .

其系统误差小于0.02角秒（峰峰值），随机误差约为±0.03角秒（1σ）。

The systematic error of this method is less than 0.02 arc second ( peak to peak ), and the random error of the measurement within the range of 0 ° to 360 ° is ± 0.03 arc second ( 1 σ) .

X射线衍射谱表明样品为纤维锌矿六角结构，但峰位向大角度方向偏移，没有新的相出现，说明钴在替位锌后使氧化锌晶格发生畸变。

XRD patterns show that the samples are hexagonal wurtzite structure , the peak shift to the large angle without new phase arising , suggesting the substitution of cobalt in zinc and the distortion of the ZnO lattice .
