计数

Counting is the combination of mathematics in one of the main content, and generating function is an important tool for counting, therefore, the mother of mathematical functions in the portfolio has an important position is to solve the problem of combination of powerful tools.

计数是组合数学中主要的内容之一，而母函数是计数的重要工具，因此，母函数在组合数学中有着重要的地位，是解决组合问题的强有力的工具。

Quiescent RASMCs were incubated respectively in 10% FBS DMEM as control group, 10% FBS DMEM supplemented with 0.1% dimethyl sulfide as vehicle group and 10% FBS DMEM supplemented with panaxynol(at concentration of 1,3,9×10-6 mol·L-1) as panaxynol groups. 1. Cell counting and double time. Cell viability was examined with trypan blue exclusion test and the cell number was counted at 0, 24, 48, 72h after the incubation using a hemocytometer.

实验中细胞分成如下几个处理组：①正常对照组：含10％FBS的培养液；②溶剂对照组：0.1％DMSO；③药物处理组：panaxynol 1、3、9×10-6 mol·L-1组。1、细胞计数及倍增时间测定：于接种并同步化后处理0、24、48、72h，用血细胞计数板计算活细胞数量，绘制生长曲线并计算细胞倍增时间。

According to the bone apposition events at the interface, we measured the osteoblast attachment rate with the hemocytometer, the osteoblast growth curve with modified MTT method, the ALPase activity and protein content of cellular layers with modified kinetic method and modified Coomassie'method respectively, and osteocalain content in the cell medium with RIA , at different levels of cell responses, as osteocompatibility indexs.

根据骨内种植体界面的骨愈合过程，分别从成骨细胞反应的不同层次选择了细胞贴壁率、细胞生长曲线、细胞层ALPase活性和蛋白质含量以及细胞培养液中骨钙素的含量作为体外评价材料骨性生物相容性的指标。采用细胞计数板计数法测定细胞贴壁率，采用改良MTT法测定细胞生长曲线。

Three kinds of chromosome morphology could be observed under oil immersion lens. The first type was condensed, which could be counted in total, but the band could not be seen. The second type was chromatosome that spread completely in the center of equatorial plate and were in metaphase. In this phase, total numbers and band were seen clearly. Last type-chromosomes had already folded and moved towards two poles and concentrated gradually, the total number of chromosomes could be counted, but banding could not be seen clearly.

在油镜下镜检可见3种染色体形态，一种呈高浓缩状态的染色体，可计数染色体总数，但不能显出带纹；第2种是已完全展开并铺于赤道板上的处于分裂中期的染色体，染色体总数和带纹显示都非常清楚；第3种是染色体已折转并向两极移动，并逐渐开始浓缩，染色体总数可以计数，带纹不能清楚显示。

Methods: This paper has collected 40323 normal reference values of Middle-aged Male's red blood cell count in 353 departments in China, using the method of microscope technique, and research the geographic distribution of normal reference value of Middle-aged Male's red blood cell count, the incliner 、complexity relationship characteristic between the normal reference value of Middle-aged Male's red blood cell count and geographic factors , including height above sea level , sunshine hours yearly , mean relative humidity yearly, mean temperature yearly , precipitation yearly, etc.

收集了中国353个单位用显微镜技术法测定的40323例中年男性红细胞计数正常参考值，运用BP神经网络和GIS空间分析，研究了其与海拔高度、年日照时数、年平均相对湿度、年平均气温、年降水量等地理因素间的非线性、复杂性关系特征及红细胞计数正常参考值的地理分布。
