An oxide of manganese found naturally as hausmannite .

一种锰的氧化物，作为黑锰矿天然存在。

At last, the Hausmannite manganomanganic oxide (Mn3O4) thin films were deposited by chemical bath deposition and the affect of different deposition parameters on the films was also discussed.

最后，通过化学浴沉积制备出黑锰矿四氧化三锰薄膜，并且研究了不同实验条件对薄膜影响。

But the latent period for reaching the platform above the water in Morris Water Maze of the Mn-exposed group was not different from that of control group. There was a significant increase in the areas,glial fibrillary acid proteinimmunoreactivity and the average proportional densities of GFAP-positive elements in nucleus caudate and accumbens in the high Mn-exposed group, and a significant reduction in the tyrosine hydroxylase immunoreactivity and average proportional densities of TH-positive elements in substantia nigra,ventral tegmentum area of midbrain and nucleus caudate in the high Mn-exposed group.

2高剂量染锰组尾状核和伏隔核的面积、胶质细胞纤维酸蛋白免疫反应强度及反应阳性产物的平均相对密度均较对照组显著升高；(3)高剂量组仔鼠黑质、中脑腹侧被盖区和尾状核的酷氨酸氢氧化酶免疫反应强度及其反应阳性产物的平均相对密度均比对照组明显下降。

The graphite and acetylene black are added to a anode material in making Zn-Mn battery, therefore the sample solution prepared appears as feculency and the titration end point of the solution is difficult to judge when active manganese in the battery is determined by iodimetry with starch as a indicator.

在测定锌锰干电池锰粉中活性二氧化锰含量时，由于制备电池时正极锰粉中添加了乙炔黑、石墨等导电材料，使制得的样品溶液显色且混浊，影响用淀粉作为指示剂进行碘量法滴定终点的判断。

Toxicity to Macrophoma musae of 13 fungicides and 3 fungicide combinations was determined in the laboratory. Macrophoma musae was highly sensitive to 70% thiophanate methyl, 70% mancozeb, 10% difenoconazole, and 72% Yijunte.

在室内测定了13种药剂和3种复配剂对香蕉黑星病菌的毒力，结果表明：香蕉黑星病菌对70%甲基托布津、70%代森锰锌、10%苯醚甲环唑和72%抑菌特敏感性较高，且抑菌效果好。

Instead of using acetylene black graphite powder, the capacity increased by 40%-50%, in 1945 in the electrolytic manganese dioxide battery of the zinc-manganese batteries discharge performance has greatly improved further.

1923年采用乙炔黑代替石墨粉，使容量提高40%-50%，1945年电解二氧化锰在电池中的应用使锌锰电池的放电性能进一步有大的提高。

The mountains about 578 meters above sea level, manganese steel by the formation of red and black from the gray of rock overlap, in which a mixture of black sandstone mountains, more than 2000 years by erosion and the formation of conical spire, a red, black and white rocks.

那山脉的海拔约578米，由红色的钢锰地层以及黑灰色的岩层交叠而成，其中黑色的山脉夹杂着砂岩，经2000多万年侵蚀而形成圆锥尖顶、红黑相间的岩石群。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
