As climate change negotiations progress,monitoring biomass and.carbon stocks is becoming an important part of the current forest ***,national governments are interested.in d.veloping forest-monitoring strategies using geospatial *** statistical method. for mapping biomass,there is a nonparametric approach called.k-nearest neighbor(kNN).We compared.four variations of d.stance metrics of the kNN for the spatially-explicit estimation of aboveground.biomass in a portion of the Mexican north bord.r of the intertropical *** d.rived.climatic,and.topographic pred.ctor variables were combined.with the Mexican National Forest Inventory(NFI)d.ta to accomplish the *** of d.stance metrics applied.into the kNN algorithm was evaluated.using a cross valid.tion leave-one-out *** results ind.cate that the Most Similar Neighbor(MSN)approach maximizes the correlation between pred.ctor and.response variables(r=0.9).Our results are in agreement with those reported.in the *** find.ngs confirm the pred.ctive potential of the MSN approach for mapping forest variables at pixel level und.r the policy of Red.cing Emission from d.forestation and.Forest d.grad.tion(REd.+).

宣威县是农村肺癌高发区。流行病学调查、毒理学实验、环境污染物的监测等研究已表明肺癌高发的原因与燃煤造成的空气污染有关。为进一步证实这一病因学说,我们对肺癌死亡率高的乡选代表性住户对不同性别的居民进行了个体接触污染物浓度的监测。同时选死亡率低的乡进行对照。监测的项目有:一氧化碳、二氧化硫、氧化氮、甲醛、挥发性有机物、气相及固相多环芳烃及多种无机元素;同时也观察了颗粒物的粒度分布及粒子的外形。结果表明,多环芳烃仍为癌症的主要原因。

美国海军研究实验室（NRl）开发出两种在UV—VIS—IR（紫外-可见光-红外）波长范围内使用的专用材料，在各种军事领域和商业应用中具有极好的性能。这两种材料是：非晶质Barium Gallo—Germanate（BGG）玻璃和多晶体铝酸镁尖晶石。BGG玻璃采用传统的玻璃熔炼加工技术，制造成本低，可替代目前制作透射窗普遍使用的材料，已经为海军侦察计划制作了许多透射窗的样机。用BGG玻璃制作的透射窗成功通过了环境耐用性试验（MIl—F-48616），抗雨水腐蚀耐久性高达300mph。现在我们正在研发BGG玻璃在高能量激光器（HEl）中的应用并对此进行评价。研发出一种烧结尖晶石的新加工方法，可以把尖晶石烧结到非常清晰、透明的程度，生产产量高。用这种新方法制造了各种不同形状（平面和圆形）、不同尺寸的透射窗，正准备将这种方法用于产业化生产各种用途的大尺寸透射窗＆整流罩。NRl还研发出一种改进型BGG玻璃，粘合时能与尖晶石和AlON基片兼容。
