本文介绍一种利用高分辨率遥感数据与数学模型绘制针叶林的新方法,适于处理空间影像数据。结果绘制出了伊尔库次克北部Ust-ilimsk地区的针叶林图。本文认为对景观判读绘制成图的GiS技术需要包括信息调查程序、地图综合数据和以目标为导向的景观图与知识的阐释。应用新方法生产预测林型动态变化的分布图,此方法使用数学分析模型在研究区数字地图上勾绘地表组成,并根据直方图勾绘典型的地表组成。

Hepatocellular carcinoma （HCC） metastasizes to the mandible is infrequently seen. Solitary bony metastasis to the mandible is rarer. The intractable bleeding caused by rupture of the metastatic HCC is challenging to clinicians. We present a case of a 74-year-old woman with HCC under control without progression for 3 years. Left facial swelling and episodes of bleeding developed recently and biopsy revealed a metastatic HCC. Computer tomography showed a large tumor in parapharyngeal space with evident mandibular ramus destruction. Bleeding occurred from the metastatic tumor but could not be controlled by electrocauterization, SurgicelTM, tissue glue, and bone wax and angiographic embolization. Palliative radiotherapy （2400 cGy in 6 fractions） was tried and the intractable bleeding was successfully stopped after the radiotherapy. Because of the hypervascular and osteolytic nature of the solitary mandibular metastatic lesion, the bleeding was troublesome. Radiotherapy provided successful control of intractable bleeding from the metastatic tumor.

The microstructure evolution, mechanical and corrosion properties of Al-11Si-2Cu-0.8Zn die cast alloy treated with Bi, Sb and Sr additions were investigated. The results of mechanical testing showed that all additions increased impact toughness, ultimate tensile strength, and elongation of the alloy as a result of change in eutectic Si morphology. The analysis of fracture surfaces revealed that with addition of Sr and to lesser extent Bi and Sb, the alloy exhibited a predominantly ductile fracture rather than quasi-cleavage brittle fracture. Moreover, with the additions of Sr, Bi and Sb, the quality index increased to 164.7 MPa, 156.3 MPa and 152.6 MPa respectively from 102 MPa for the base alloy. Polarization corrosion tests conducted in sodium chloride solution showed that the corrosion potential shifted to more negative values with additions of Sb, Bi and Sr, respectively. Corrosion immersion tests also revealed that the element additions have a detrimental effect on the corrosion rate of alloys, due to the increase of boundaries between the Al and eutectic Si phases.
