The PLK method for a class of singular perturbed equation;
一类奇摄动方程的PLK方法
To investigate expression of!plk-1 gene and PLK-1 protein in acute leukemia patients and its clinical significance, and to observe the distribution of PLk-1 protein in acute leukemin cells, the mononuclear cells were separated from the bone marrow or peripheral blood of acute leukemia patients, bone marrow benign proliferation individuals and normal individuals.
为了探讨急性白血病细胞中plk-1基因及其蛋白的表达情况和意义,并初步了解PLK-1蛋白在急性白血病细胞中的分布情况,通过抽取急性白血病患者、骨髓良性增生者及正常人的骨髓或外周血单个核细胞作为研究对象,应用RT-PCR技术及流式细胞术检测plk-1mRNA和PLK-1蛋白在急性白血病细胞中的表达,用荧光显微镜观察PLK-1蛋白在急性白血病细胞中的分布。
This paper determines the ideal environmental capacity by using the A value method,distributes the environmental resource by using the AP and AS methods,which achieves the standards of both the concentration and the total amount.
通过A值法核定理想环境容量,采用AP,AS法对环境资源进行分配,从而达到“浓度与总量双达标”。
