The immunoregulation activity of SPG-1 mainly existed in the part of sugar chain, but keeping its molecular structure intact had some effects on its immunoregulation activity; SPG sulphation had reducing effects on the immunoregulation of SPG-1, whereas, after medium and low acetification of SPG, the immunoregulation of SPG was enhanced. Conversely after high acetification, the immunoregulation of SPG-1 decreased, that is, after introducing sulfuric and acetic acid base in SPG-1, its immunoregulation changed. All of these indicated the structure of SPG-1 was closely connected with its immune activity.⑤.

甘薯糖蛋白SPG-1的免疫调节活性主要在其糖链部分，但保持分子结构的完整性对其免疫调节的活性有一定的作用；甘薯糖蛋白硫酸化对甘薯糖蛋白SPG-1的免疫调节有降低作用，而中、低度乙酰化后，可提高甘薯糖蛋白的免疫调节作用，高度乙酰化后则降低其免疫调节作用，即甘薯糖蛋白引入乙酰基和硫酸基团后，其免疫调节活性发生了改变，这些均表明了甘薯糖蛋白的结构与其免疫调节活性有密切的关系。

From the detailed simulation results and analysis,for the emulational frame based on minimum zone set,the route discovery mechanism of DSR is independent of nodes mobility,every once,the source node acquires a route to a target node which its relative position is alterant,the routing time is steady but not be effected by nodes mobility,the conclusions are obvious helpful for reducing route tip and increasing routing efficiency.

通过对选取总路由流量，路由平均跳数、平均路由发现时间的实验数据分析发现，对于基于最小区域集的仿真框架，DSR的路由发现机制并不受节点移动性的影响，每次源节点获得一条到达相对位置已改变目的节点的新的路由的时间并不受节点的移动性影响而趋于稳定，可明显减少路由跳数，增加路由计算效率。

By then, a number of important and out of Beijing's main-line trains will be calling at two stations, north-east, Shanghai-bound trains can be changed starting from Beijing West Railway Station, Beijing Railway Station stop, and go to Guangzhou, and Chengdu, the direction of the train may also be replaced by Beijing station of origin or through the Beijing West Railway Station.

Iron and steel materials to apply a wide range of reasons, first of all, the ingredients can be used to span, and from close to non-carbon content of pure iron to about 4% of cast iron, alloy, in this context, the phase structure and microstructure are great change; In addition, a variety of thermal processing is to process, in particular, metal heat treatment technology, a substantial change in composition and properties of alloys.

钢铁材料适用范围广阔的原因，首先在于可用的成分跨度大，从近于无碳的工业纯铁到含碳4％左右的铸铁，在此范围内合金的相结构和微观组织都发生很大的变化；另外，还在于可采用各种热加工工艺，尤其金属热处理技术，大幅度地改变某一成分合金的组织和性能。

In addition, digital controllable ports of the padded delay cell are parametric, so the parameter can be configured at different design stages to change delay and offer flexible timing of IP core interface.

另外，弹性延迟单元中的数字控制端采用参数化可配置设计，数字控制端的参数值可以在设计的各个阶段自由重置，从而改变IP核接口的延迟，增加IP核接口的时序柔性。

Pig oocytes cultured in vitro for some time were inseminated by frozen–thawed ejaculated sperm. At specified times after insemination, sperm penetration, cell cycle progression and mitogen-activated protein kinase phosphorylation were evaluated. It was shown that:(1) oocytes at various maturational stages could be penetrated by sperm;(2) sperm penetration did not affect meiotic cell cycle progression;(3) sperm penetration of germinal vesicle oocytes and maturing oocytes did not alter MAPK phosphorylation; and (4) when premetaphase I and metaphase I oocytes, in which MAPK was activated, were fertilised, no evident MAPK dephosphorylation was detected as in metaphase II oocytes.

不同成熟阶段的猪卵与精子融合后体外培养发现：(1)不同成熟阶段的猪卵母细胞都可被精子穿透；(2)精子穿透不影响减数分裂细胞周期进程；(3)精子穿透GV期卵母细胞和正在成熟的卵母细胞不改变MAPK磷酸化：(4)已受精的前中期I和中期I卵母细胞的MAPK有活性，MAPK不像MII卵母细胞那样受精后发生磷酸化。

The detail microstructure, composition and optical property of the films have been explored through RBS, XPS, Raman, XRD and IR spectroscopes. The negative bias dependent film growth on the influence of grain size, preferred orientation, and density within grain boundary and volume densification was a significant phenomenon for hetero-deposition.
