Kangsheng mnlti - nutriment has plenty of glucosan , which is an immunity - adjust agent and acclerant , can increase the quantity of macrophage in human bady , and rise up the activity of acidic phosphatase and kill - rate towards cancer cell , also atrophy the tumor and adsorb the mycotoxin 康圣天元多价营养素含有丰富的葡聚糖，它是一种免役调节和促进剂，能增强人体内巨噬细胞的数量，提高酸性磷酸酶的活力，增强体内对癌细胞的杀伤力，使癌细胞萎缩，同时能吸附真菌毒素。
Meanwhile , the male mice deficient for germ - cell cyritestin are infertile . therefore , both spl7 and cyritestin are important molecules in the process of fertilization . nevertheless , people can not get fully satisfied the results in some contraceptive researches for their limited effects respectively 其n端含有去整合素结构域，然而多数实验结果表明单一应用这些分子所获得的免疫性避孕效应非常有限，从而提出今后的研究方向是更具抗原性或良好运载体系的新型多价疫苗。
Abstract ： based on present plant gene engineering techniques , some strategies to develop transgenic crops expressing multiple genes by constructing a multigenes expression vector or a number of expression vectors and then making one or more transformations or co - transformation are discussed and the prospects are described as well in this paper 摘要本文探讨了在利用植物基因工程技术的基础上，通过构建多基因或者多个表达载体，进行一次、多次基因转化或共转化方法获得转多价基因作物的一些策略，并进行了展望。

Lithium vanadium oxides display high capacity and low price as cathode materials for lithium ion batteries . lithium vanadium oxides , however , are hard to be synthesized because of the various valences of vanadium . if the factors of price and comprehensive electrochemical properties a re considered , the cathode materials of ( lithium ) vanadium oxides should be recognized as the most potential cathode materials for lithium ion batteries (锂)钒氧化物类正极材料容量大、价格低，但由于钒的多价态导致(锂)钒氧化物类正极材料制备困难，如果考虑价格和综合电性能等因素， (锂)钒氧化物类正极材料更具有实际使用价值，所以(锂)钒氧化物类正极材料被越来越多的研究者认同为是新一代最具发展潜力的锂离子电池正极材料。
