重数

By using the limits of functions and the exchange limit theorem,we considered the relationship between the double limit of function with two variables and its repeated limit s.

Results Sheep spleen polypeptides could significantly stimulate multiplication and transformation of mice's spleen lymphocytes; increased markedly the weight of spleen and the thymus; promoted delayed hypersensitivity; increased the quantity of antibody-producing cells; increased the level of serum hemolysin; promoted the expurgation effect and the phagocytic function of monocyte/macrophage and increased the activity of natural killer.

结果 羊脾多肽能使小鼠脾、胸腺增重，明显刺激小鼠的脾淋巴细胞增值，促进小鼠迟发型变态反应作用，提高小鼠抗体生成细胞数，提高小鼠的血清溶血素水平，但促进小鼠单核－巨噬细胞碳廓清作用不明显，增强小鼠的单核－腹腔巨噬细胞吞噬能力，有效提高小鼠自然杀伤细胞活性。

The major breakthrough from a physically point of view occurred in 1985 when Halsey et al. introduced the function f . In 1995, Olsen gave a strict mathematical Multifractal Formulism. Meanwhile, Cawley, Mauldin, Arbeiter and Patzschke et cetera published articles on these topics.

之后，Frish和Benz等人将此概念推广到动力系统中吸引子的分形结构。1985年，Halsey等人从物理和直观的意义上作了突破性的工作，在测度的谱和集合的分形维数之间建立了联系。1995年，Olsen提出了严格的重分形形式体系的数学框架。

Symptoms less daily stool frequency of more than 10 times below the yellow green stool with mucus and was蛋花汤kind, and accompanied by a slight abdominal distension, hyper sound肠鸣; severe diarrhea when the performance of frequent dozens of times daily defecation, were water samples, volume, and acid odor, or vomiting accompanied by galactorrhea.

较轻的症状多为每日大便次数在10次以下，粪便呈黄绿色，带粘液且呈蛋花汤样，并伴有轻微腹胀，肠鸣音亢进；较重时多表现为腹泻频繁，每日排便数十次，呈水样、量多，有酸臭味，伴有溢乳或呕吐。

Mainly for the "loss" of the heavy market, holding hundreds of billions of China Life's cash will be invested to do what?

Kiln always have weight of kiloton, length of hectometer and four to nine supporting aprons. It is a statically indeterminate system with heavy load, large torque and multi-supporting mechanism.

回转窑通常重达千吨、长过百米，支承组数4～9档，是一种重载、大扭矩、多支点、超静定运行系统，运行中由于轴线变化导致载荷分配严重不均，引发多种机械故障与安全事故。

The results were as follows:The embryo-bud length, embryo-shoot length, embryo-shoot number and dry weight of embryo-shoot of maize inbreed line decreased evidently under osmotic stress within germinating period. So the germination date was delayed, the germination rate and viability decreased.

研究结果如下：在萌发期渗透水分胁迫条件下，玉米的胚芽长、胚根长、胚根条数、胚根干重等均有明显的下降，因而发芽时间延迟，发芽率下降。
