礦床勘探課程設計的主要內容是估計礦床的遠景;分析礦體的變化性;選擇勘探范圍，勘探手段，勘探工程布置形式;確定取樣，編錄和儲量計算方法;進行勘探投資預算，計算開采后的總利潤，並進行經濟評價;繪出必要的圖表，並寫出文字報告 -
Given the high - dimensionality ( thousands of genes ) and small sample sizes ( often < 30 ) encountered in these datasets, an honest assessment of sampling variability is crucial and can prevent the over - interpretation of spurious results
Dna晶元數據具有高維（成千上萬個基因）和樣本小（通常小於30 ）的特點，為了避免對偽結果進行分析，準確估計抽樣方差很重要。 -
The analyst of isotropy indicated that the sample spots of 12 soil nutrient contents ( except total nitrogen ) were correlated in given spatial range. the semi - variogram values increased when the distances were enlarged, and nugget lied in, which meant the existence of spatial variability structure, and sample spots were correlated in the 50 - meter of sampling distance
各向同性分析的結果表明： 12種（除全氮）土壤養分在一定的范圍內觀測值之間存在著空間相關性，變異函數（ h ）隨間距增大而增大，且有基臺值，說明存在空間變異結構特徵，在50m的采樣間距內存在空間相關性。
