We generalize the mass transference principle established by Beresnevich &Velani to limsup sets generated by rectangles.More precisely,let fxngn≥1 be a sequence of points in the unit cube [0,1]d with d ≥ 1 and frngn≥1 a sequenceof positive numbers tending to zero.Under the assumption of full Lebesguemeasure theoretical statement of the set{x ∈2 [0,1]d:x ∈ B(xn,rn),for infinitely many n ∈ N}.we determine the lower bound of the Hausdorff dimension and Hassdorff measure of the set {x ∈ [0,1]d:x ∈ Ba(xn,rn),for infinitely many n ∈ N}.where a = (a1,...,ad) with 1 ≤ a1 ≤ a2 ≤...≤ ad and Ba(x,r) denotes a rectanglewith center x and side-length (ra1,ra2,...,rad).When a1 = a2 =...= ad,the result is included in the setting considered by Beresnevich & Velani.

通过对本实验室筛选到的山东链霉菌(Streptomyces shandongensis)进行发酵,采用大孔吸附树脂X-5和HP-20联用的方法,对发酵液中所含的广谱抗真菌活性成分进行了提取,得到了纯度在89%以上的淡黄色粗品,该粗品的效价与制霉菌素的效价相似。经制备型HPLC收集的样品,低温真空旋转蒸发后冻干得到了纯度在95%以上的白色粉末状纯品。该纯品经紫外光谱扫描、质谱、核磁共振等手段进行结构
