The corrosion rate of plain carbon steel contacted with higher coalification such as anthracite coal is 2 to 3 times larger than that in brown coal .

在相同的其它条件下，碳钢的腐蚀速率随接触的煤的煤化度提高而增加，与发育良好的无烟煤接触的碳钢的腐蚀速率是在煤化度相对较低的褐煤中的2～3倍以上。

The more the increase of cooling rate or pre-deformation, the more the secondary dendrite arms are easy to coarsen.

冷却速率越大或预变形处理以后的试样在熔化过程中更容易发生二次枝晶臂之间的合并。

Most of non-equilibrium microstructures in the original microstructure dissolve into the α-Mg matrix due to the diffusion of the solute and then the remainder is melted firstly. The more the increasing of cooling rate or pre-deformation, the more the secondary dendrite arms are easy to coarsen.

原始组织中的非平衡共晶组织在加热过程中大部分扩散溶解而溶入基体中，剩余部分在加热过程中首先熔化；冷却速率越大或预变形处理以后的试样在熔化过程中更容易发生二次枝晶臂之间的合并。

The paradox between economic development and ecological environment in the coastland is quite sharp. The rate of economic development in the coastland is quicker than any regions in our country. In the same time, the ecological environment of it is relatively vulnerable and variable.

沿海地区是我国经济发展速度最快的地区，同时也是我国生态环境相对脆弱易变的地区，其经济发展与生态环境的矛盾表现得尤为尖锐。

The results showed that the coating rate increased with increasing reation temperature and SnCl_4 flux,but the coating morphology got worse with the gas viscosity increasing,the coati...

结果表明，反应温度和SnCl＿4浓度升高，包敷速率加快，包敷形态变差；背景气氛粘度增大，包敷形态变优，包敷速率减小；操作气速增大，包敷速率加快，包敷形态变优。

The recovery rate of cobalt of the entire process is over 95%.

且整个流程钻的回收率达95%以上。

Two intestinal parasite species were discovered,Coccidia,Capillaria and the infection rate were 18.08% and 3.64%,respectively.

对62种鸟类共110份粪便样品进行调查，查出2种寄生虫，寄生虫总感染率为20%，球虫和毛细线虫的感染率分别为18.08%和3.64%。

The third was to compare the effects of the different floating liquids on the growth of the rabbit coccidia oocysts. Magnesium sulfate solution showed the smallest influence rate (4.94%) and saturated salt water (7.47%) had the largest.

其三，不同漂浮液对兔球虫卵囊发育影响作用比较；结果表明硫酸镁溶液影响率最小(4.94%)最大的是饱和食盐水(7.47%)。

Morphological conversion from spiralto coccoid forms occurred when HP was cultured with selenium and most of coccoid forms had fragmentary flagella and pilus; the effection of selenium to activity of urease, catalase, alkaline phosphatase is not exist or not evidence; selenium enable pET32a-vacA-E.coli BL21 which can express VacA produce yellow lipochrome, and the color become deeper with increasing of concentration of selenium; selenium can decrease expression of recombined VacA by restrain the growth of pET32a-vacA-E.coli,but can not influence activity and gene sequence of VacA; selenium can enhance the suppression effect of recombined VacA for gastric cancer cell, depress the index of cell multiplication and the forming rate of colony, decrease the number of cell in S period, increase total of cell in G period; After purified, the recombined VacA can be identified by VacA antibody.

体外实验结果表明：一定浓度的硒作用HP后，HP菌落数量随着硒浓度的增加而减少，菌落颜色由灰白色变为砖红色，溶血现象随硒浓度的增加和作用时间的延长而逐渐消失，HP的形态由弯曲形变为球形或椭圆形，鞭毛及菌毛出现脱落现象；硒对尿素酶、过氧化氢酶、碱性磷酸酶活性无影响或影响不明显；一定浓度的硒能使表达VacA的pET32a-vacA-E.coli BL21工程菌产生脂溶性砖红色色素，颜色随硒浓度增加而加深；一定浓度的硒通过抑制pET32a-vacA-E.coli BL21工程菌的生长，减少重组VacA表达量，但不影响其空泡毒活性及编码基因序列；纯化后的VacA重组蛋白可被VacA抗体识别，具有良好的抗原性。

The shaping method of noncircular part and the tool holder's radial motion characters in noncircular turning process are discussed in detail in the thesis.

论文详细研究了非圆零件的成型方法和加工过程中刀架的径向运动规律。
