阅读以下技术说明和C代码，将C程序中(1)～(5)空缺处的内容填写完整。[说明]某种传感器的输出值Ratio依赖于环境温度temp(-40℃≤temp≤50℃)。对一组环境温度值(ITEMS个)，已经测量得到了相应的Ratio值(如表4-10表格所示)。表4-10粗略地描述了曲线Ratio(temp)。校正系数K是Ratio的倒数，因此也依赖于环境温度temp。在数据处理中，需要用更多的列表值细致地描述曲线K(temp)，如表4-11所示。在表4-11中，各温度值所对应的K值是对表4-10进行线性插值再求倒数得到的，具体的计算方法如下。1) 根据temp值，在表4-10中用二分法查找；2) 若找到相应的温度值，则按相应的Ratio值求倒数得到K值；3) 若没找到相应的温度值，则可确定temp所在的温度区间[Tp1,Tp2]，同时获得了相应的Ratio1和 Ratio2，再按如下公式计算K值：在程序中，当temp高于50℃或低于-40℃C时，设定K=0。[C程序]includetypedef struct {int Temp; /* 环境温度 */double Ratio; /* 传感器的输出值 */}CURVE;define ITEMS 7double GetK(int Temp,CURVE *p,int n){ /* 用二分法在n个元素的有序表p中查找与Temp对应的传感器输出值 */int low, high, m;double Step;low = 0;high = n-1;if ((Temp＜p-＞Temp) || (Temp＞(p+high)-＞Temp))return 0.0; /* 超出温度范围时返回 0.0 */while (low＜=high){ m=(1);if (Temp==(p+m)-＞Temp)return (2);if (Temp＜(p+m) ＞Temp)high=m-1;elselow=(3);}p+=high;Step=( (4) )/((p+1)-＞Temp-p-＞Temp);return 1.0/ (p-＞Ratio + Step*( (5) ) ;}void main(){ int Degree;double k;CURVE Curve [ITEMS]={{-40,0.2},{-20,0.60.},{-10,0.8},{0,1.0},{10,1.17},{30,1.50},{50,1.8}};printf ("环境温度 校正系数\n");for (Degree=-40;Degree＜=50;Degree++){ k=GetK ( Degree, Curve, ITEMS);printf("%3d %4.2f\n",Degree,k);}}
阅读以下说明和C程序，将应填入(n)处。[说明]某种传感器的输出值Ratio依赖于环境温度temp(-40℃≤temp≤50℃)。对一组环境温度值(ITEMS个)，人们已经测量得到了相应的Ratio值(见表1)。该表粗略地描述了曲线Ratio(temp)。校正系数K是Ratio的倒数，因此也依赖于环境温度temp。在数据处理中，人们需要用更多的列表值细致地描述曲线K(temp)，如表2所示。在表2中，各温度值所对应的K值是对表1进行线性插值再求倒数得到的，具体的计算方法如下：1．根据temp值，在表1中用二分法查找；2．若找到相应的温度值，则按相应的Ratio值求倒数得到K值：3．若没找到相应的温度值，则可确定temp所在的温度区间[Tp1, Tp2]，同时获得了相应的Ratio1和Ratio2，再按如下公式计算K值：Step=(Ratlo1-Ratio2)/(Tp1-Tp2)K=1.0/(Ratio1+Step*(temp-Tp1))在程序中，当temp高于50℃或低于-40℃时，设定K=0。[程序]include ＜stdio.h＞typedef struct {int Temp; /*环境温度*/double Ratio; /*传感器的输出值*/}CURVE;define ITEMS 7double GetK(int, CURVE*, int);void main(){int Degree;double k;CURVE Curve[ITEMS]={ {-40,0.2},{-20,0.60},{-10,0.8},{0,1,0},{10,1.17},{30,1.50}, {50,1.8} };printf("环境温度 校正系数\n");for( Degree= 40; Degree＜=50; Degree++){k=GetK(Degree, Curve, ITEMS);printf(" %3d %4.2f\n",Degree,k);}}double GetK(int Temp, CURVE *p, int n){/*用二分法在n个元素的有序表p中查找与Temp对应的传感器输出值*/int low,high,m; double Step;low=0; high=n-1;if((Temp＜p-＞Temp) ||( Temp＞(p+high)-＞Temp))return 0.0; /*超出温度范围时返回0.0*/while (low＜=high){m=(1) ;if(Temp==(p+m)-＞Temp)return (2);if (Temp＜(p+m)-＞Temp)high=m-1;else low=(3);}p+= high;Step=((4))/((p+1)-＞Temp-p-＞Temp);return 1.0/(p-＞Ratio +Step *((5)));}
