The results show that Re-K-Zn compound modificator has remarkable effects in high Chromium white cast iron when the modificator has 0.5%Re+2.0%K+0.008%Zn. The modificator not only or bar-like carbides but also improved the mechanical properties of high chromium white cast iron,with its impact toughness enhanced from 7.0J/cm2 to 11.7J/cm2 and its hardness enhanced from 54HRC to 57HRC, and the wear resistance increased by 350%.

However, iron precipitate could hardly be found by scanning infrared microscopy in the specimen annealed lower than 1100℃ so that iron-precipitation temperature in monocrystalline silicon or cast multicrystalline silicon could not be determined.

然而，用红外扫描电镜等很难观察到热处理温度低于1100℃处理过的样品中是否存在铁沉淀，所以无论是对于直拉单晶硅还是对于铸造多晶硅，很难确定铁的沉淀温度。

It was different of contents of same mineral element inthe leaves of Malania olefera because of different areas, but the differences was notnotable. The influence of mineral element and soil elements on Malania olefera wasnitrogen, iron, manganese, zinc, potassium, copper from most to least, and four ofthem were belong to microelement. However, the lack of copper and serious lack ofzinc and iron in the soil influent the growth of Malania olefera. It had been made through the analysis of morphologic and anatomicalcharacteristics of root, stem, leaf, flower, fluid and seed that Malania olefera notonly had the primitive character but also had the evolution character, which had thevital significance on Olacaceae classification.

砂粒含量比大，通透性良好的土壤适宜蒜头果的生长；六个不同分布区土壤的有机质和全N含量极为丰富，速效K的含量水平中等，而土壤速效P的含量富贫差异较大；分布区土壤部分缺Cu，严重缺Zn、Fe；蒜头果叶片中的叶绿素含量与立地条件有着密切的关系；龙虎山样地立地条件比其他样地更适合蒜头果生长；不同立地上生长的蒜头果叶片中同一矿质元素含量有一定的差异，但差异不显著；土壤元素对蒜头果生长的影响由大到小依次为：N、Fe、Mn、Zn、K、Cu，其中四个是微量元素，而分布区土壤缺乏Cu，严重缺Zn、Fe而影响了蒜头果的生长发育。

However, due to its high-phosphorus iron ore oolitic hematite, phosphate ore has reached 0.3%-1.8%, much higher than the phosphorus content of iron ore industry must be 0.2 percent in the standard, coupled with transportation inconvenience that this has been sleeping underground mineral resources to be developed in the state.
