a.消费(C)：居民或个人用于物品和劳务的支出,包括耐用消费品和非耐用消费品的支出.比如居民购买电视机、衣服.b.国内私人投资总额(I)：国内企业为了未来生产更多物品和劳务而用于购买物品中的支出总额,包括资产投资和存货投资两大类.比如企业购买厂房、新的设备.c.政府购买(G)：各级政府在商品与劳务上的总支出,它是国内总需求的组成部分之一.如政府建立法院、提供国防、外交、公共交通等服务.d.政府转移支付(TP):政府对个人的并不是用于购买个人所提供的产品和劳务的支付,它只是一种简单的收入转移,政府转移支付不计入政府购买.如政府给老年人发放的社会保障津贴.e.出口(X):表示收入从国外流入以购买本国产品的支出.如美国人购买我国的衣服.2.解释总供给曲线.区别供给曲线上点的移动和供给曲线的移动.什么能够通过供给曲线上的点的移动来增加产出?什么能通过移动总供给曲线来增加产出?总供给曲线：反映了价格水平与产量的相结合,即在某种价格水平时整个社会的厂商所愿意供给的产品总量,表示的是总供给与一般价格水平之间的关系.在其它条件不变的情况下,由于价格水平的变动所引起的总供给的变动,在图上表现为供给曲线上点的移动.在价格水平不变的情况下,由于其它条件的变化所引导起的总供给的变动,在图上表现为供给曲线的移动.因为总供给与一般价格水平是正相关的关系,因此价格水平的上升可以通过供给曲线 上的点的移动来增加产出.当政府实行刺激总供给的政策即扩张性的财政政策和货币政策时,会使供给曲线向右边移动,从而增加产出.3.没看懂.4.市场存在市场失灵的情况,这时需要政府干预,而政府干预的主要手段是财政政策和货币政策.通过IS-LM模型分析：凯恩斯经济下,LM曲线是一条水平线,扩张性的财政政策使IS曲线向右移动,结果是使收入增加而利率不变,所以在凯恩斯经济下,政府实行财政政策非常有效.在垂直的经济即在古典经济下,LM曲线是一条垂线,这时扩张性的财政政策使IS曲线向右移动,结果是使收入不变而利率增加,此时政府实行财政政策无效.5.西方经济学中菲利普曲线有短期和长期之分,短期的菲利普曲线是一条向右下方倾斜的曲线,长期的菲利普曲线是一条垂直线.货币学派是将预期因素加入了菲利普曲线,没有改变曲线的形状,短期的依然是一条向右下方倾斜的曲线,长长期的是一条垂线.

没有上下文,不是很确定script 和copy的意思,供参考

若 AB为等腰三角形的底,则：
作 垂直于直线y=-x+5 且过AB在此直线上的中点（2/5 ,2/5)的直线
直线为 y=x
即 C(0,0)
AB=BC时
设C(0,y) |BC|=|AB| 即 1+(y-4)²＝﹙1－4﹚²＋﹙4－1﹚²→y＝4± 17½
AC=AB时
C(0,y) |AC|=|AB| 即 16+(y-1)²＝﹙1－4﹚²＋﹙4－1﹚² →y=1±2½ 1加减 根号2
即C(0,0)；（4±17½）；（1±2½）
