锇

The company integrates production and sales in the one-stop, operates mainly in the following items and product one, precious metal chemical raw materials: Rhodium powder, palladium powder, iridium powder, ruthenium powder, platinum powder, gold powder, rhenium powder, osmium powder, silver bullion, silver grain, Yang Polar silver plate, palladium chloride, 59.5%, ammonium chloride, palladium 50.3%, K Wong, fill port, K White fill port, 925 silver fill port, K gold solder films and so on.

公司集生产与销售于一条龙，主要经营以下项目与产品一、贵金属化工原料：铑粉、钯粉、铱粉、钌粉、铂粉、金粉、铼粉、锇粉、银锭、银粒、阳极银板、氯化钯59.5％、氯化铵钯50.3%、K黄补口、K白补口、925银补口、K金焊片等。

Results:Methyl aldehyde can"t preserves efficiently the ultrastructure of the renal biopsies.Osmium tetroxide can preserves efficiently it but affects dyeing of the section for light microscopy.However,glutraldehyde not only preserves it better than methyl aldehyde but also doesn"t affect dyeing of the section for light microscopy.

结果：甲醛固定不能有效保存肾穿组织的超微结构，锇酸的固定能有效地保存超微结构，但严重影响了光镜切片的染色；而戊二醛与甲醛相比，较好地保存了肾穿组织的超微结构，同时又不影响光镜切片的染色。

Methods:The renal biopsies is fixed respectively by methyl aldehyde,glutraldehyde and osmium tetroxide (OsO\-4) after glutraldehyde before paraffin embedding and is observed with light microscopy and electron microscopy.

在石蜡包埋前，肾穿组织分别用甲醛、戊二醛及戊二醛、锇酸双固定。

Iridium hard wear-resisting, the iraurita pen tip is more durable than the ordinary pen nib, key in this "small dot" on.

锇铱合金坚硬耐磨，铱金笔尖比普通的钢笔尖耐用，关键就在这个&小圆点&上。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
