The second phase of networking ,which occurred in the 1960s ,included three major milestones:software switching, digital transmission ,and satellite deployment,in 1965 ,american telephone and telegraph introduced the first stored program control local switch ,the 1 ees switching system ,with the ues of software control, a family of custom calling services (speed calling,call waiting ,call forwarding and three way calling ,etc ,) was mande possible, the first software program for the 1ees switching system had approximately 100,000 lines of codes, today switches may contain ten million lines of code.

第二阶段是网络化，其发生在20世纪60年代，包括三大里程碑：软件交换，数字传输，卫星的运用，在1965年，美国电话电报介绍第一个存储程序控制区域交换机，第1 ees交换系统中，软控制运用在家庭式的呼叫服务中（快速呼叫，呼叫等待，呼叫转接和三方呼叫等，成为可能，第一个软件程序，为1ees切换系统大约有 10万行代码今日交换系统可能含有1千万行的代码。

These results indicated that the genetic variation within exon 2 appeared to have largely arisen by gene recombination and balancing selection. Alignment of the deduced amino acid sequences of the β1 domain coded by exon 2 revealed 6 synonymous mutations and 27 nonsynonymous substitutions at the 33 disparate sites.

In this study, with a total of 798 SOC density data and the 1:500 000 soil maps, the SOC storage in YunnanGuizhouGuangxi Region of China (including Yunnan province, Guizhou province and Guangxi Zhuang Autonomous Region) was estimated using the soil type method with the linkage of arithmetic mean method, median method, and areaweighted mean method (based on the area recorded in the Soil Series) based on different map units and the results were compared with that of the linkage of PKB method (Pedological Professional Knowledge Based Method).

利用中国滇黔桂地区（云南省、贵州省和广西壮族自治区）798个土壤剖面及1∶[KG-*2]50万土壤图在不同的制图单元水平上，分别采用算术平均值法、中值法和面积加权平均值法（以土种志中的面积为权重）估算了该地区1 m深度SOC储量，并与基于土壤学专业知识连接方法（Pedological Knowledge Based Method， PKB）的估算结果进行了比较。

The results showed that:(1) some governing points, which were measured by submeter precision GPS, were utilized to correct the 1 m precision remote sensing image and it could satisfy the desired precision of geometrical correction, therefore, this method could be used as geometrical correction in the region where was short of the big scale relief map;(2) the density of the original data was the main factor to affect precision of the volume, and the precision of the calculated volume of earthwork could be improved to more than 90% when using the test points and feature points; the sparser the data density were, more significant could be improved; On the base that elevation of test points were measured by the submeter precision GPS, the error of the volume, which was produced by vectoring relief map to obtain DEM, could be calculated, and the calculation precision of the earthwork could be improved markedly.

结果表明：利用平面精度达亚米级的GPS测量控制点坐标对1米分辨率的遥感卫星影像进行几何校正，能够满足其几何校正的精度要求，可以解决缺乏大比例尺地形图地区的高分辨率遥感卫星影像的几何校正问题；通过对模型数据的分析，数据密度是影响体积精度的主要因素，利用检测点高程和特征点可以提高土方量计算的精度，使土方量计算的精度达到90％以上，数据密度越稀疏，精度提高越显著；采用高程精度达厘米级的RTK(Real Time Kinematic实时动态差分)测量检测点的高程，对用地形图扫描矢量化形成的DEM模型进行检测求出误差体积，可以大大提高土方量的计算精度。

The B, C, D group each mouse right armpit department hypodermic vaccinates the H22 lump cell to hang fluid 0.2ml, after vaccinating 24h weighing, and starts the abdominal cavity injection to give the medicine: A, B group uses physiological saline 0.2ml/only (continuously to give medicine 14 days) every day, C group with 5 fluorine uracil mg/day, dilutes the density is mg/0.2ml (the 1~5th day for medicine), D group will put down with the physiological saline disappears the hitch to compound mg/only (continuously to give medicine 14 days).

依据随机化原则，将40只ICR雌性小鼠随机分为四组，分别为空白对照组，荷瘤对照组，5氟尿嘧啶组，平消栓组。B，C，D组每只小鼠右腋部皮下接种H22瘤细胞悬液0.2ml，接种24h后称重，并开始腹腔注射给药：A，B组每日用生理盐水0.2ml/只（连续给药14天），C组用5氟尿嘧啶25mg/kg（第1~5天给药），D组用生理盐水将平消栓配制成1.0g/kg（连续给药14天）。
