针对8051 MCU 产品，我们通过串口提供ISP 升级方法，用户需要在LDROM 区域下载BOOT 程序。

将MCU 调试下载器或其他串口工具和MCU 相连接，并利用WayOn ISP Programer Tool 软件完成升级。

1.1.软件简介WayOn ISP Programer Tool 是维安半导体有限公司针对8051系列MCU 开发的ISP 下载工具，配合8051 MCU 调试器支持一键下载功能。

工具支持UART 通讯方式，默认采用38400的波特率，下载文件支持BIN/HEX 格式，BOOT 程序支持的串口管脚RXD 为引脚P04，TXD0为引脚P05，RST 引脚为P20。

维安8051 MCU 支持默认从APROM 启动，配合维安调试器的串口和GPIO 管脚连接目标MCU 串口和P20（P20配置为RST ），完成ISP 升级。

同时支持默认选择从LDROM 启动，利用普通串口连接目标MCU 串口，在上电启动周期（客户可配）之内完成升级启动完成ISP 升级。

八年级英语数词单选题60题1. There are ___ floors in this building and I live on the ___ floor.A. five; fifthB. fifth; fiveC. five; fiveD. fifth; fifth答案：A。

本题考查基数词和序数词的用法。

“five”是基数词，表示数量“五”；“fifth”是序数词，表示顺序“第五”。

第一空表示“有五层楼”，用基数词“five”；第二空表示“在第五层”，用序数词“fifth”。

2. My birthday is on ___ of May.A. threeB. the threeC. thirdD. the third答案：D。

“third”是序数词“第三”，序数词前要加“the”，表示“五月的第三天”，所以用“the third”。

3. We have ___ classes every day.A. sixB. sixthC. the sixD. the sixth答案：A。

“six”是基数词，表示“六”，这里是说“每天有六节课”，用基数词“six”。

快乐8是一种非常受欢迎的玩法，其中任选5是一种非常具有挑战性的玩法。

在这个玩法中，玩家需要从1-80的数字中任意选出5个数字，如果这5个数字与号码中的数字完全一致，那么就可以获得丰厚的奖金。

很多人都会问快乐8任选5有多难中？今天我们就来详细探讨一下这个问题。

我们需要了解的是，快乐8任选5的中奖概率是非常低的。

具体来说，快乐8一共有80个数字，而任选5的组合数为80C5，即80个数字中选取5个数字的组合数，计算公式为：80!/[(80-5)!*5!]，其结果为258,048。

也就是说，快乐8任选5的中奖概率为1/258,048，非常之低。

我们需要注意的是，快乐8任选5的中奖概率与所选数字的组合有关。

具体来说，如果玩家选择的5个数字都是相邻的数字，那么中奖的概率就会更低。

因为在快乐8的过程中，相邻的数字很少会同时出现在号码中。

如果玩家想要提高中奖的概率，就需要选择一些不相邻的数字，这样才能增加中奖的机会。

我们还需要了解的是，快乐8任选5的中奖概率还与所选数字的个数有关。

具体来说，如果玩家选择的数字越多，那么中奖的概率就会越高。

因为在快乐8的过程中，开出的数字越多，中奖的机会就会越大。

如果玩家想要提高中奖的概率，就可以选择更多的数字，这样就能增加中奖的机会。

快乐8任选5的中奖概率非常低，但是如果玩家选择的数字不相邻、数量较多，那么中奖的机会就会相应增加。

要想在快乐8任选5中获得丰厚的奖金，还需要有一定的运气和技巧。

玩家在选择数字的时候，不仅需要考虑到数字的组合，还需要注意到自己的运气和技巧，这样才能在快乐8任选5中获得更大的成功。

例88 五因素三水平正交实验某聚合反应，用原来的工艺生产的产品粘度是80～85s。

现要求生产年度为90s的产品，需要更换催化剂步骤一：确定因素和水平，并选正交试验表。

该题共有5个因素，3个水平，又要求考虑交互作用，因此选择L27(313)正交试验表。

步骤四：结论1、从方差分析表可以看出，催化剂的种类、使用量、单体活性和催化剂种类与反应强度的交互作用的统2、其他因素可以认为无影响。

3、A*D交互作用有显著影响。

由表一变换后的数据可求出A0D0：-14A0D1：0A0D2：-17A1D0：0A1D1：-7A1D2：4A2D0:13A2D1：-1A2D2：5MAX:13即最大的为A2D0.MIN:-17即最小的为A0D2.4、B和C的值。

B0：-33B1：-2B2：18C0：-16C1：-13C2：12因此，B2和C2是最佳条件。

因此，黏度最大的最佳条件应选择A2B2C2D0其总体均值估计值为û=(A2B2C2D0)=85+13/3+18/9+12/9-2*(-17/27)=93.995%的置信区间为93.9-2.12*（1.32*13/27）^0.5<X<93.9+2.12*（1.32*13/27）^0.5即92.2<X<95.6因此,（ad）11（ad）12（ad）13-334.962963-331.962963-328.6296296（ad）21（ad）22（ad）23-337.2962963-336.6296296-340.2962963（ad）31（ad）32（ad）33-339.2962963-346.2962963-341.962963Max-328.6296296MIN-346.2962963需要更换催化剂，相应要求调整反应条件。

该聚合反应所用溶剂中希望回收20%溶剂。

反应条件如下反应强度的交互作用的统计量F值均大于F分布表的显著性检验临界值，对黏度有高度的影响。
