Dianci bileiqi, 1989 等静压法依据的原理是,在液体和气体介质中压力在各个方向的传播是相同的.如果对装在模子内的料施加等静压,会形成致密的结构,焙烧后会均匀地收缩.与此相反,用传统的方法在制品内会产生定向结构,形成性能与压力的关系.用等静压法很方便地制造高压绝缘子.此法的主要优点:产品尺寸精确,性能无各向异性现象,由于没有干燥工序,生产周期比传统工艺短,作业面积小,废品少,能制造形状复杂的制品等等.等静压法可制得致密的氧化铝瓷,其强度等于一般压制材料的强度 ...

野生动物学报2022年3—6月，于黑龙江帽儿山森林生态系统国家野外科学观测研究站开展小斑啄木鸟（Dryobates minor）取食偏好的调查。采用样方结合样线与无线电追踪技术追踪小斑啄木鸟，采用基于“利用-可利用型”方法的Bailey’s方法分析小斑啄木鸟取食树木与取食生境的偏好，采用主成分分析归纳影响选择取食地的主要因子，利用Fisher’s精确检验、非参数检验和相关性检验探究性别在取食行为中及主要因子间的差异。结果显示：小斑啄木鸟偏好在活立木上，用轻啄的方式，在冠层处、侧枝上短时取食；株密度、取食树高度、坡度、
