三、多元线性回归分析 (一)模型p50 预报对象Y,m个预报因子x,(i=12m)建立它们之间的相关关系得到多元线性回归方程。如下:(4-18)

(1)∵内能是态函数,故△Eabd=△Eac 故 Oadb AE adb +Wadb =224+42 =266(J) (2) =AEba +Wba =-AEacb Wha =-224-84=-308(J)放热 (3) ad= d +Wad =(Ed-E)+Wadb =168+42=210(J) Qab=△Ea+O=E-Ea =(E-Ea)-(E-Ea)=Ea-168 =△Eacb-168=224-168=56(J) 8-21mol单原子理想气体i=3

The general approach Earlier Parts have given a broad picture of the economic environment within which marine transport operates, and the mechanics of making economic calculations. Ship design links the two, i.e., the marine transport requirements must be developed into a series of feasible ship designs

第7章蜗传动 7.1.1蜗杆传动的特点和应用 特点: 1.传动比大:结构紧凑,动力传动i=7~80; 2.传动平稳:连续的螺旋齿;逐渐进入啮合和退出,故冲击小、噪声低; 3.可自锁:升角小子当量摩擦角时; 4.传动效率低:滑动速度大,摩擦与磨损严重。但新型蜗杆的传动效率已可达90%以上

定义1如果两个矩阵A=[ai]和B=[b]的行数和列数分别相等,且各对应元素也相等,即a=b (i=1,2m;j=1,n),就称A和B相等,记作 A=B

In this chapter you will learn the Is curve, and its relation to the Keynesian Cross the Loanable Funds model the LM curve, and its relation to the Theory of Liquidity Preference how the IS-LM model determines income and the interest rate in the short run when P is fixed
