5.1坐标数据文件 坐标数据文件是CASS最基础的数据文件,扩展名是“DAT”,无论是从电子 手簿传输到计算机还是用电子平板在野外直接记录数据,都生成一个坐标数据文 件,其格式为: 1点点名,1点编码,1点Y(东)坐标,点X(北)坐标,1点高程 N点点名,N点编码,N点Y(东)坐标,N点X(北)坐标,N点高程 说明:

1.复数列的极限设{an}(n=12)为一复数列 ,其中an=an+ibn,又设a=a+ib为一确定的复数 如果任意给定ε0,相应地能找到一个正数 N(a),使|an-aN时成立,则a称为复数 列{an}当n→∞时的极限,记作 此时也称复数列{an}收敛于a

1.试证明 Brent定理:令W(n)是某并行算法A在运行时间T(n)内所执行的运算数量, 则A使用p台处理器可在t(n)=((n)p+(n)时间内执行完毕

22.2 N,N-Dimethylcycloheptylamine may also be named as a dimethyl derivative of cycloheptanamine. -N(CH3)2 N,N-Dimethylcycloheptanamine 22.3 Three substituents are attached to the nitrogen atom; the amine is tertiary. In alphabetical order, the s substituents present on the aniline nucleus are ethyl, isopropyl, and methyl. Their positions are

The estimate of x based on N data points can then be made without reprocessing the first N, points. Their effect can be included simply by starting with pseudo observation which is equal to the estimate based on the first N points having a variance equal to the variance of the estimate based on N The same is true of the variance of the estimate based on N

根据相律:气液平衡相应的类型是很多的。 例:N=3,N,=2,则N,=3则这个体系要在三维空间上图解 Nc=3,Np=1,则N,=4则这个体系要在四维空间上图解。 我们暂时限于讨论二元两相系,Nc=2,Np=2,N-2
