软件破解时间限制
crack常见技巧
运行时间限制
一、运行时间限制
这种程序是每次运行的时间有限制，如运行10分钟，20分钟等情况。
它们里面一般有个计时器，让我们假设这程序每秒减一，其会用上DEC指令。一般的程序是32位，你反汇编后查找"dec dword ptr"，如运气好的话，有可能给你提供重要的线索。
当然实现这种功能方法很多，需要我们多接触这种类型就能掌握。
3、还有一种方法是常用的，把系统时间调后，程序将出现到期的警告窗，然后记下警告窗的一些提示语言，在W32DASM中利用串式数据参考功能（ string reference）查找，然后分析代码，CRACK它。
另外，有一点要注意的，如这对话框或警告窗是中文的，在W32DASM是找不到相应的中文字串的，你可用十六进制工具把相关的中文的提示改成英文，如其提示：“你的使用时间到期”。你用十六进制工具把这改成：“Trial Time has expired”（注意改后的字节不可超过原文的字节数），再用W32DASM查找字串。
附：FILETIM 类型定义
类型定义Type FILETIME ' 8 Bytes
dwLowDateTime As Long
dwHighDateTime As Long
End Type说明windows提供了一种特殊的机制，可以记录文件的访问及创建时间。在win32环境中，这些信息以64位值的形式保存，量度的是自1601年1月1日以来经历的100ns时间单位数量（64-bit number specifying the elapsed time since January 1, 1601, in 100-nanosecond increments.）字段表字段类型及说明dwLowDateTimeLong，Low and high-order 32 bits of the file timedwHighDateTime注解文件时间在系统中通常用“协同世界时间”（UTC）的格式保存，但同时提供了在UTC及本地时间之间转换的函数。FILETIME结构里可包含UTC或本地时间——由我们自行决定在结构中包含什么时间
光耦参数及资料
市场常见光耦内部图：光电耦合器（简称光耦）是开关电源电路中常用的器件。
光电耦合器分为两种：一种为非线性光耦，另一种为线性光耦。
常用的4N系列光耦属于非线性光耦常用的线性光耦是PC817A—C系列。
非线性光耦的电流传输特性曲线是非线性的，这类光耦适合于弄开关信号的传输，不适合于传输模拟量。
线性光耦的电流传输手特性曲线接进直线，并且小信号时性能较好，能以线性特性进行隔离控制。
开关电源中常用的光耦是线性光耦。
如果使用非线性光耦，有可能使振荡波形变坏，严重时出现寄生振荡，使数千赫的振荡频率被数十到数百赫的低频振荡依次为号调制。
由此产生的后果是对彩电，彩显，VCD，DCD等等，将在图像画面上产生干扰。
同时电源带负载能力下降。
在彩电，显示器等开关电源维修中如果光耦损坏，一定要用线性光耦代换。
常用的4脚线性光耦有PC817A----C。
PC111 TLP521等常用的六脚线性光耦有：TLP632 TLP532 PC614 PC714 PS2031等。
常用的4N25 4N26 4N35 4N36是不适合用于开关电源中的，因为这4种光耦均属于非线性光耦。
以下是目前市场上常见的高速光藕型号：100K bit/S:6N138、6N139、PS87031M bit/S:6N135、6N136、CNW135、CNW136、PS8601、PS8602、PS8701、PS9613、PS9713、CNW4502、HCPL-2503、HCPL-4502、HCPL-2530（双路）、HCPL-2531（双路）10M bit/S:6N137、PS9614、PS9714、PS9611、PS9715、HCPL-2601、HCPL-2611、HCPL-2630（双路）、HCPL－2631（双路）光耦合器的增益被称为晶体管输出器件的电流传输比 (CTR)，其定义是光电晶体管集电极电流与LED正向电流的比率(ICE/IF)。
光电晶体管集电极电流与VCE有关，即集电极和发射极之间的电压。

日语文字编码
⽇语⽂字编码1、常⽤编码⽇语的⽂字编码主要是Shift_JIS、EUC-JP、ISO-2022-JP这三种。
（1）Shift_JIS主要是Windows和Macintosh使⽤的⽂字编码。
Shift_JIS 的⽂字集合基本是按照JIS X 0208规定的。
但实际上各个⼚商各⾃进⾏扩展，包含了⼤量重复的、规格以外的⽂字。
因此，Windows在本来的 Shift_Jis的⽂字集合之外，⼜增加了NEC扩展、IBM扩展所包含的⽂字。
这种规格和实际情况的分歧长期存在，随着windows-31J的规格化，混乱情况有所改善。
（2）EUC-JP是被Linux和Solaris⼴泛地使⽤的⽂字编码。
（3）ISO-2022-JP主要被Email使⽤的⽂字编码。
只使⽤7个bit，第8个bit不使⽤，所以不适合程序中的字符串处理，主要使⽤在⽹络中的数据交换中。

开关电源启动后，N801（KA5Q1265RF）3脚的供电由开关变压器T801的8脚输出经VD803整流来提供，此时N801正常工作时此脚为23V，电流需维持在10mA以上。
整机电源的保护电路：过压保护：N801（KA5Q1265RF）的5脚为该电源芯片的保护脚，当开关电源出现异常情况使输出电压异常升高时，开关变压器的T801的8脚输出经VD804、R806、VD802整流、限流加到N801（KA5Q1265RF）的5脚，当此脚收到异常升高的电压时，N801（KA5Q1265RF）即保护，此电源停止工作。
联想19寸宽屏液晶显示器电源LD7575PS故障排除一例
联想19寸宽屏液晶显示器电源LD7575PS故障排除一例刚到新单位，自己使用的一台联想19寸液晶显示器就罢工了。
前一晚睡觉前把电源都关了，第二天早上起来显示器死活不开机，电源指示灯也不亮了，典型的电源板故障！心想可能还是跟前几次的故障一样，所以也没放在心上，出去干活儿了。
中午回来，按了几下电源钮，还是没反映，心想不行，得下手赶紧修了，下午还有网络会议要开，耽误不得。
找来工具，卸下下部四颗螺钉后，面板取不下来，用力撬了撬边缘，有点不大对头。
最后打开后才明白，这个面板是很好拆的：先卸除下部的四颗螺钉，将面板向上推，就轻松取下了。
之后拆下TFT和背光组件，拔除灯管线和驱动板的连线，取下电源板上的铁壳，拆下电源板如下图（没带相机，借用网上一张，顺便给商家打个广告）：电源板上有三只电容680微法/25V（C211、C212、C213)鼓包，但均未爆浆，从旧CRT显示器上拆下两只25V1000微法和1只480微法/25V电容替换，故障依旧。
看来故障有点棘手。
接好电源测5V和14V电压输出分别为:~，。
5V供电明显偏低，从而引起驱动板芯片无法正常工作，按电源键开机无法进行。
该电源主控芯片为LD7575PS,次级电压从5V支路上取样，通过反馈电路到芯片2脚。
查反馈支路上各元件，依次更换了IC202(TL431)，C210(470p)，主滤波电容150微法/450V，光耦817B，当用817C 光耦替代817B后，5V电压升至之间波动，14V电压升至，上下波动。
由于450V的滤波电容体积过大，无法放入机壳内，用起子放电后，又将原机滤波电容换上，开机没电压又降至，怀疑放电过程中损坏了光耦。
测光耦输入端电压差几乎为0，又用421光耦替换817C，开机电压升至，接显示器电源灯依然不亮。
从网上下载主控芯片的资料，各脚功能如下(不想翻译了，有兴趣的自己查吧）：从上图看，反馈支路上的大部分元件均更换排查过，维修陷入困境。
至此，唯一的可疑元件转移到了主控芯片LD7575PS上。

光耦817c工作原理
光耦817c工作原理
光耦817c是一种将输入电信号通过光耦合器转化为输出光信
号的电子元件。
它由发光二极管（LED）和光敏晶体管（LPT）组成。
光耦817c的工作原理如下：
1. 输入电信号经过电阻器限流，进入LED。
2. LED受到电信号激励后，产生光能，通过发射端发射出去。
3. 发射出的光线照射到光敏晶体管的接收端。
4. 光敏晶体管的接收端感受到光能后，产生电流。
5. 产生的电流经过输出电阻器，形成与输入电信号相对应的输出电信号。
光敏晶体管光敏区的光电效应和储能效应是使光耦具有可见光控制的主要原因。
当LED处于导通状态时，LED引入的光照
射到光敏晶体管的光敏结上，使该结中的载流子复合，导致其电导下降。
因此，当输入电信号的电平为高时，LED导通，
光照射到光敏结上，光敏晶体管电导减小，输出电信号的电平为低。
反之，当输入电信号的电平为低时，LED截止，无光
照射到光敏结上，光敏晶体管电导增加，输出电信号的电平为高。
光耦817c常用于电气隔离、信号传输、电源控制等领域。
它
具有隔离电气信号、抗干扰能力强、响应速度快等特点，是一种常见且常用的光耦合器。

它可以将输入的电信号转化为光信号进行隔离和传输，从而达到保护电路和提高信号质量的作用。
在使用817c光耦时，需要注意它的引脚使用方式，本文将为大家详细介绍817c光耦的引脚使用说明。
817c光耦有四个引脚，分别为VCC、GND、PIN1和PIN2。
其中，VCC和GND是电源引脚，用于给光耦提供电源。
PIN1和PIN2是输入输出引脚，用于输入电信号和输出光信号。
下面将分别介绍这四个引脚的使用方式和注意事项。
1、VCC引脚VCC引脚是817c光耦的正电源引脚，一般接在正极，用于给光耦提供电源。
在使用时，需要根据应用场景来确定电源电压的大小和极性。
在工作过程中，VCC引脚的电压应该不能超过绝对最大额定电压范围，否则光耦会受到损坏。
2、GND引脚GND引脚是817c光耦的负电源引脚，一般接在负极，用于电路的共地。
在使用时，需要注意电源的接法，以免出现电源接反等错误操作。
同时，在光耦的输入端和输出端都应该接入GND引脚，以保证信号传输的稳定性和可靠性。
3、PIN1引脚PIN1引脚是817c光耦的输入引脚，用于接收电信号。
在使用时，需要将输入信号与GND共地，并通过电阻限流，以保证输入端电流不超过硅管的额定电流。
同时，需要注意输入信号的带宽和幅值范围，以免过大或过小，导致光发射二极管或光接收二极管无法正常工作。
4、PIN2引脚PIN2引脚是817c光耦的输出引脚，用于输出光信号。
在使用时，需要将输出信号与电路相应的部分接入，并用光纤或其他光导材料传输。
同时，需要注意输出信号的功率、频率和波形，以满足系统的需求。
综上所述，817c光耦引脚的使用是电路设计中十分重要的一步，需要按照设计要求进行正确接线，以确保电路的正常工作和信号的稳定传输。
除了以上提到的四个引脚，817c光耦还有其他规格和参数需注意，如光耦的各种限值和特性指标，以及光耦的使用环境和工作条件等。

氰烯菌酯综述
氰烯菌酯综述中国创制农药中的精英——氰烯菌酯市场占有率不断提升《农药快讯》《现代农药》编辑部柏亚罗与甲氧基丙烯酸酯类杀菌剂不同，氰烯菌酯为氰基丙烯酸酯类杀菌剂；与主流杀菌剂⼤多⼴谱不同，氰烯菌酯更专注于⼩麦⾚霉病和⽔稻恶苗病。
氰烯菌酯具有独特的化学结构，在众多创制农药中独树⼀帜。
其作⽤机理虽仍未明确，但从其与⼤多数市售杀菌剂⽆交互抗性来看，其作⽤机理与众不同；初步研究推测，其作⽤靶标为肌球蛋⽩-5（myosin-5）。
2007年底登记的氰烯菌酯，2014年实现了亿元的销售额，有望成为国内继扬农氯氟醚菊酯（2012年销售额亿元）之后，第2个迈⼊亿元⽅阵的创制产品。
对于氰烯菌酯，江苏省农药研究所股份有限公司及其兄弟单位全⽅位做了⼤量、细致的研究⼯作。
这些研究结果证明了氰烯菌酯的优秀性能，展⽰了其对环境的友好态度，凸显了它的独到之处，同时也收获了⽤户和市场对氰烯菌酯的⾼度认可和可观回报。
国内创制农药约50个，⽽氰烯菌酯就这么“任性”，凭借其专注的特性将⾃⼰锻造成精品。
⼩麦⾚霉病和⽔稻恶苗病的抗性发展呼唤新药剂的诞⽣⼩麦⾚霉病是由⽲⾕镰孢菌（Fusarium graminearum）引起的世界性流⾏性病害，是我国⼩麦⽣产中最重要的病害之⼀，主要发⽣在江淮流域、西南冬麦区及东北春麦区，⼩麦扬花期遇⾬极易流⾏。
⾚霉病不仅能引起⼩麦⼤幅减产，甚⾄绝收，⽽且⾚霉病菌分泌的毒素——脱氧雪腐镰⼑菌烯醇（deoxynivalenol，DON）可致⼈畜中毒。
⾃1972年我国⾸次筛选出多菌灵防治⼩麦⾚霉病以来，取得了令⼈满意的效果，抽穗扬花期喷施多菌灵等苯并咪唑类杀菌剂是我国⾃70年代以来防治⼩麦⾚霉病的关键措施之⼀。
但⾃1992年南京农业⼤学周明国教授等在浙江海宁市⼩麦病穗上检测到世界⾸例⽲⾕镰孢菌抗药性菌株以来，发现抗药性病原群体⽐例迅速上升，抗药性病原菌分布范围不断扩⼤。
华东地区已因抗药性⽽⾯临着多菌灵等现有杀菌剂对⾚霉病防治失效的风险。
