查询词典 cuprous

NF 77 is a light duty cutting oil for all general operations of non-ferrous metals including cuprous metals, aluminium and their alloys. NF 77 contains special lubricity fortifiers to impart quick release of chip from tool. The low viscosity ensures the good cooling and flushing properties, which are essential for high speed machining.

NF 77 是一款專為非鐵金屬而配製的切削油，適用於銅金屬、鋁金屬及其合金的一般輕度切削，含有特殊潤滑添加劑，使屑片容易與刀具分離，低的黏度確保了足夠的冷卻及沖屑性能，都是高速切削所必需。

NF 99 is a heavy duty cutting oil for all general operations of non-ferrous metals including cuprous metals, aluminium and their alloys. NF 99 contains chlorinated additives, fatty oil and special lubricity fortifiers to impart quick release of chip from tool even under extreme high cutting pressure. The low viscosity ensures good cooling and flushing properties, which are essential for high speed machining.

NF 99是一款專為非鐵金屬而配製的切削油，適用於銅金屬、鋁金屬及其合金的重負荷切削，含有氯化物、脂肪及特殊潤滑添加劑，增進其極壓及潤滑性能，就算在高切削壓力下，也能使屑片容易與刀具分離，低的黏度確保了足夠的冷卻及沖屑性能，都是高速切削所必需。

First firing of raw materials are usually basic glaze frit, in the process of production need to add metal oxides, metal ions is also a special color of the enamel glaze color, or as a gel, or suspension-like particles of the dispersion or absorption of light and color, for example, cobalt oxide blue or purple, blue green copper oxide, cobalt oxide copper oxide mixture is significant blue, red cuprous oxide, nickel oxide in the potassium content of the glaze was red, in the sodium yellow glaze of green, if used alone was brown iron oxide, cobalt oxide and manganese dioxide are combined black or dark brown.

通常是先将原料烧成基本釉的熔块，在制作的过程中再加入需要的金属氧化物，也就是以金属离子特具的颜色而使珐琅釉呈色，或成为胶状，或悬浮状的粒子对光线的色散或吸收而呈色，例如氧化钴呈蓝或紫色、氧化铜呈蓝绿色、氧化铜混和氧化钴则显青色、氧化亚铜呈红色、氧化镍在含钾之釉中呈红色、在含钠之釉中呈黄绿色，又如氧化铁单独使用呈褐色，与氧化钴及二氧化锰合用则呈黑色或黑褐色。

This thesis took the complexes of cupric or cuprous salts with small molecular amines to mimic oxidoreductases. The coordination environment of the active centers of the catalysts can be modified by changing the ratio of copper/amine. The oxidation of naphthols and 2-naphthylamine under the copper amine complexes led to some novel reactions and products.

本文利用简单易得的小分子有机胺与铜盐制成络合物，模拟氧化还原酶，通过改变铜胺配比等因素来调整催化剂活性中心的配位状态，从有机合成的角度研究其对萘酚类和2-萘胺等底物的氧化性质和催化氧化性质，发现了一些新颖的仿生氧化反应和产物。

Thus,LD83 canensure a perfect surface quality and protect live of dies.LD83 performs a high standard of bacteria and fungi control,and prolongs the sump life,The built in corrosion inhibitor prevents starning to cuprous metals and even aluminum alloys.

因此。LD83能高效能控制细菌和毒菌的滋长，进而延长了乳化液的使用寿命，内含饿腐蚀抑制，能防止铜金属或铝金属的腐蚀。

Raffinates, steam-cracked C4 fraction cuprous ammonium acetate extn, C3-5 and C3-5 unsatd

含饱和及不饱和C3-5但不含丁二烯的残油，来自蒸汽裂解C4馏分的

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
