SEM micrographs showed that the PS colloidal crystal template spheres (diameters 275±10 nm) arrayed into hexagonally close-packed layers. The synthesized 3DOM SnO2 microparticles were circularly or hexagonally porous and the thin porous walls were formed by nanocrystals of SnO2. The macroporous diameters of the 3DOM SnO2 were between (215±10) nm and the thicknesses of the porous walls was between 20～30 nm.

SEM图表明PS胶晶模板微球排列规整，大小均匀(直径275±10 nm)，形成多层六方紧密堆积排列；煅烧除去模板后的3DOM SnO2呈三维多孔网络结构，具有圆型和六边形的孔隙形貌，其孔径大小为(215±10) nm；孔壁由SnO2纳米晶粒组成，壁厚为20～30 nm。

When the embryo reached the prehatching stage, the hatching enzyme granules were secreted into the perivitelline space from the top of HGCs. Secretory granules were spherical and 0.5-1.0 μm in diameter. The hatching enzyme was dissolved in the perivitelline fluid, where it gained access to the egg envelope and digested the inner layer of the egg envelope.

至孵化前期时，孵化酶颗粒自HGCs顶部的开口分泌出来，分泌颗粒呈圆球形，直径为0.5-1.0 μm，有的以单体的形式存在，有的粘结成团。

The clutch contains friction disk about 300 millimetre in diameter. It also contains a spring arrangement and a pressure plate for pressing this disk tightly against the smooth rear face of the flywheel.
