小学四年级下册奥数题100道及答案(完整版)
小学四年级下册奥数题100道及答案(完整版)1. 简便计算：25×125×4×8答案：（25×4）×（125×8）= 100×1000 = 1000002. 小明在计算加法时，把一个加数十位上的0 错写成8，把另一个加数个位上的6 错写成9，所得的和是532。
正确的和是多少？答案：把一个加数十位上的0 错写成8，所得的和就多了80；把另一个加数个位上的6 错写成9，所得的和就多了3。
所以正确的和是532 - 80 - 3 = 4493. 果园里有梨树、桃树和苹果树共1200 棵，其中梨树的棵数是苹果树的3 倍，桃树的棵数是苹果树的4 倍。
求梨树、桃树和苹果树各有多少棵？答案：苹果树：1200÷（1 + 3 + 4）= 150（棵）；梨树：150×3 = 450（棵）；桃树：150×4 = 600（棵）4. 某工厂一车间和二车间共有100 人，二车间和三车间共有97 人，一车间和三车间共有93 人。
三个车间各有多少人？答案：三个车间总人数：（100 + 97 + 93）÷2 = 145（人）；一车间：145 - 97 = 48（人）；二车间：145 - 93 = 52（人）；三车间：145 - 100 = 45（人）5. 学校买了4 个足球和2 个排球，共用去162 元。
每个足球比每个排球贵3 元，每个足球和每个排球各多少元？答案：假设全买的足球，总价要多2×3 = 6 元，所以足球的单价：（162 + 6）÷（4 + 2）= 28（元）；排球单价：28 - 3 = 25（元）6. 鸡兔同笼，共有头30 个，脚86 只。
求鸡、兔各有多少只？答案：假设全是鸡，兔：（86 - 30×2）÷（4 - 2）= 13（只）；鸡：30 - 13 = 17（只）7. 一条公路长1200 米，在公路的两旁每隔20 米栽一棵树，两端都栽。

YTCC2015赛季开荒物价表
2015图文物价表仅供参考，开荒期物价浮动很大，请以实际成交价为准。
主要写给不清楚物价的新人看的，老人无视。
这季偷懒了，都是抄袭前几季的，只是稍微改动了下，有些都不太适用了。
只收录常用物品交易，高级装备基本不收录，不清楚价格的请在群上询价。
变异类物品根据基础物品价格看货加价，极少交易的物品请自行议价。
一、材料类基本货币CY加3J换算比例跟据市场需求不定期变动开荒换算为1JN=230C后市看涨，1JM=115C，1JS=40C公式放在那的，预计3J价格会有所上涨，但浮动不会很大。
黑塔4C，一个月后逐渐下跌到3C万能4C，一个月后逐渐下跌到3C锻造10C，一个月后逐渐下跌到6C神秘之珠=10C书源5C等于JM，新手别NPC，或是给人黑了开荒初期用量极大价格很高，以后逐渐下跌，4S-6S是主流价格以稳定为主。
无孔=15C，一个月后逐渐下跌到5C1S ＝交易用基本无价值2S ＝ 5C3S ＝12C4S ＝ 25C5S ＝45C6S ＝80C8S ＝ 300C骷髅=1.5C 在做伤害珠的基础上还能做元素珠，后期KH养点元素珠紫宝石=1C 伤害珠材料开荒物理伤害热门其他宝石均为1c，后期看跌注意前期抗性少都要用到开荒价价PG都差不多,后面PG会分化用量大的会涨，用量小的会跌.符文类，注意1到5号符文单个要买来做符文用的1C计价，开荒3#可回法有点用处，可3个1C交易，开荒过后大量的无交易价值，15#单个买卖4C一直会坚挺的FW有这些是10# 12# 16# 18#19# 23#，注意25到32#，会是高开低走的，只有少数较挺 ,一般来说后面14 15也用来合16注意43以上的FW可以通过3合1来合中级符文，这季33#能合龙珠，所以价格会比较稳定。
6#=0.7C,7#＝0.5C 8#＝0.7C，9#=0.7C，10#＝1.5-2C（后市看涨，最高2C）40以下FW没有交易价值，如收单个做符文，均1C算，注意40以上可合热门FW的，都有保底价，不要让某些人黑了。

TPCR系列硬币投币计时器与硬币总计器及计时器说明书
TPCR SERIES COIN VENDINGTIMERSTANDARD COIN TOTALIZER & VENDING TIMERPower is applied to the unit at all times prior to and during timing.Coin switch closures are counted until their total equals the dipswitch setting. At this point the output contact transfers and the time delay begins. Upon completion of the pre-selected time delay the output contact reverts to its original position and the control resets. Removal and re-application of input power will reset the control.ACCUMULATING VENDING TIMERPower is applied to the unit at all times prior to and during timing. Coin switch closures are counted until their total equals the dip switch setting. At this point the output contact transfers and the time delay begins. For every coin switch closure counted, prior to or during timing, the unit adds the time set to the total vending time. Upon completion of the time delay, the output contact reverts to its original position and the control resets. Removal and re-application of input power will reset the control.ACCUMULATING VENDING TIMER/LAST COIN INDICATORSame as ACCUMULATING VENDING TIMER except when the remaining time is less than the set time, the last coin indicator is activated. If additional coins are added the last coin indicator is deactivated until the remaining time is again less than the set time.P .O.

大白菜鲁白15
大白菜鲁白15
一、品种介绍：鲁白15为青岛农业科学研究院（原青岛农业科学研究所）承担“八五”国家科技攻关项目（85-004）的子专题。
该品种抗病、丰产、风味品质良好，属中晚熟大白菜优良新一代杂种；鲁白15植株披张，开展度72.8厘米，株高47.6厘米，球顶平圆，叠抱，球高28.9厘米，直径22.9厘米，单球重4.5-5公斤，生长期80-85天，整齐一致，丰产，平均每亩产净菜7000-8000公斤。
在全国区域试验及生产试验中，平均每亩产叶球6420公斤，比对照鲁白1号和鲁白10号增产27%以上，净菜率达到73.36%。
经过“八五”攻关专家组统一鉴定，该品种具有高抗病毒病，抗霜霉病和黑斑病，被确定为“三抗”品种，达到了国家规定的育种考核目标的要求。
1995年通过国家科委组织专家组的验收，1997年通过山东省农作物品种审定委员会审定，2001年8月通过全国农作物品种审定委员会审定。
二、经济效益：自2001年以来，该品种深受山东、江苏、浙江、湖南、河南、河北等省市农民欢迎，已成为全国范围内的大白菜主栽品种；共销售良种38662.5公斤，累计推广种植2.062万hm2，实现经济效益231.73万元，创社会效益1.96亿元。
产品具有极高的应用价值和推广潜力。
预计可累计推广10年，能实现经济效益750万元，创社会效益6.36亿元。
