Mark, Jew, a Daniel is come to judgment!" Shylock, finding himself defeated in his cruel intent, said, with a disappointed look, that he would take the money. And Bassanio, rejoiced beyond measure at Antonio's unexpected deliverance, cried out: "Here is the money!" But Portia stopped him, saying softly: "There is no haste. The Jew shall have nothing but the penalty. Therefore prepare, Shylock, to cut off the flesh; but mind you shed no blood; nor do not cut off more nor less than just a pound; be it more or less by one poor scruple, nay, if the scale turn but by the weight of a single hair, you are condemned by the laws of Venice to die, and all your wealth is forfeited to the state." 下期续 to be continued.

Then came a yell and noises of coins and keys falling on the floor. In her excitement to see Sean, she almost knocked down the woman waiting outside the elevator. Fortunately only the woman's purse was knocked to the floor with its content spilled out and rolling in different directions. But unfortunately a pair of glasses also fell out which Molly stepped on before she could stop. "I'm so sorry!" Molly quickly apologized and bent down to help the woman pick things up. "I'm so sorry!" The woman stared at Molly. Brownish hair with green streaks, Molly did not look like a typical nurse to her despite the white gown she was wearing. "How can you be so careless? Nurses should be more careful!" said the woman. "Nurses nowadays." At that moment Molly recognized the woman. She was the same woman in Sean's room earlier. Molly wanted to introduce herself, but it just didn't seem like a good time for that. "I'm sorry," apologized Molly once more. "Can I pay for your glasses?" "Do you think money can pay for everything?" in her moment of annoyance, Pearl blurted out what was in her mind. Molly didn't know how to respond to that, but really wanting to pay for the woman's losses, she pulled out some large banknotes and dropped them into Pearl's purse. This made Pearl really angry, who quickly fished them out and threw them to the floor. Molly was shocked, wondering what she had done that made the woman so angry. "I'm sorry," Molly apologized yet one more time and picked up the money. Pearl got up and walked into another elevator that just arrived, leaving Molly holding the money. 下期续 to be continued.

I clean my room, wash the dishes, and sometimes help Mommy sweep the floor, dust, or make dinner. I also have to take care of Buster. I feed him two times every day, and I make sure that he is clean and that he stays out of trouble. Daddy bought a big red brush for Buster and told me that I should brush Buster when his fur is messy and matted. Buster enjoys being brushed. But sometimes when Buster's fur is very tangled, I try to be very gentle so that i will not hurt Buster when I brush him. Even if it does hurt him, he does not get mad. After I finish brushing Buster, his fur is soft and smooth and shiny, and if he has been a good dog, I give him a treat. 您知道吗？校园剪影 College Collage - life in North American university 搜寻留言板 My name is Adam Neil and I am a college student in America.

[mp3] 校园剪影向错走,向右走 Lost in the Bike Race One of the classes I took last year was a physical education class, which in America is often called gym class. One of the tests that I had to complete for the class was a mountain bike race. The race was about 25 kilometers long, and each student had to finish the race in less than four hours to pass that test. The bike race went well, and I finished the race easily. However, we all waited at the finish line for a long time, because two of the girls had not returned. After two hours of searching for them, we finally found them. They had made a wrong turn and got lost. We were all glad that they were safe, but we still made fun of them for getting lost.

我发表了一篇视频贴，大伙来看看吧~

进来来看看SDR的同步检波效果，无存在声音变调或啸叫

这个PL990的同步检波效果，不太满意，理论上不应该有损音质，视频中显示音质已完全变味，想玩同步检波，就买SDR吧

南京CDR接收视频

PL310ET短波太垃圾，收衰落大点的台，S/N老是归零，S/N低于8就会声音轻而无力，整体听感就是声音一伸一缩的

PL310et短波声音抖动厉害，我的Gospell GR-216一样是DSP，但不会抖动

Elektor SDR收黑龙江 DRM 13710kHz

D39L小机子，天线缩至最短，插入河水中，不管是FM还是短波，信号都会增强，根据显示屏的信号强度显示，天线接触河水的接收效果不比空中拉长天线差多少。神奇了

DRM改频 17790改成15620，功率减小，发射方位角不变。但信号变强了

海尔CDR数字广播接收机有货啦！有需要的吗？价格与上次一样，488元，想玩的来。至于有没有覆盖，见我的另一贴“粗暴方法检测CDR信号的存在”，“收集各地CDR”，百度搜就能搜到我的贴子

新老几代CDR机一览

看下这两款CDR接收机，外观如何？这个好像支持蓝牙了

粗暴方法检测CDR信号的存在请大家帮个忙，例如你当地的大功率中国之声频率是100.0MHZ，请用一个DSP收音机放在接收最强的位置，然后调到100.2MHz，你会听到沙沙的杂音，调到100.3MHz，沙沙杂音消失，再调到99.8MHz，听到沙沙的杂音，然后调到99.7MHz，沙沙杂音消失，则可以初步确定CDR在播。简单说一下原理，CDR数字信号居于FM的两侧，现在需要你们把这两侧的数字信号检测出来，最有效的方法是用SDR，频谱仪等设备扫描频谱图，但大伙都没有SDR，那只能用收音机了，收音机接收频率调到两侧的数字边带上是可以听到特别的杂音，但不会极易听到。之所以选DSP是因为它选择性好，之所以要在信号最强的位置，是因为数字功率很低，只有在信号强的位置，粗暴方法检测到数字信号的成功率就高些

2018北京CCBN展会上收集到一些图片（持续更新）海尔的CDR工程机也展出了，带LCD点阵屏的那台便是，能滚动显示中文信息

看机！猛货！海尔CDR新款样机不知道有没有做台标，EPG，天气，授时等功能，反正到时应该会做。北京的吧友可以到CCBN看海尔展台上的这个机，现场体验！展台在8A601

还有与D39L类似的吗？这机真真正正迎合了我的需求，耳机线可当天线，全波段DSP，小巧放口袋，显示参数，立体声，功能多……好像很难找到类似的机了，我现在对传统机和体积大的机没什么兴趣了

理论上可以，就是不知道效果

就发个图

到广州收CD 频率89.3，数字节目1无音频，数字节目2是中国之声，而不是娱乐广播，这是好事，可以享受到不一样的CDR节目，数字节目3是乡村之声，这个一样。其中数字节目2音量比FM稍微小一点点，数字节目3声音则明显偏小。数字节目2和带内FM都是中国之声，中国之声数字节目对比FM延迟3秒左右，我来回切换对比音质，我是木耳朵，个人感觉数字听感好些，中国之声FM声音有点闷，数字声音则更通透。我在离发射塔8公里的地方，信号是挺强的，室内也不用拉天线，移动接收效果也很好。但是广州CDR信号数模功率比偏低了点，这体现在广州CDR与带内FM接收效果对比上，当带内FM噪声稍大点时，CDR已无法解码，所以数字功率占比要调大点才好，目前规划数字功率是模拟FM功率的4%，太低了，调到10%就会很爽。还是我老家的CDR信号调试得好，FM噪声大得听不清，CDR仍然正常解码

FM达到无法察觉底噪的程度你们的FM机器插耳机听强台立体声模式能不能达到无法察觉底噪的程度？我手里的一些机达不到，有些机把音量关到最小，还是有底噪，估计是低放部分的热噪声？D39L很差，强台都有不小的底噪。有资料称，因模拟技术的限制，输出音频信噪比最多只能达到60dB，请问60dB是否还能被察觉到底噪？

凯隆D39L的充电电路有问题吗？电池拆开，用原配的电源插上，量电池仓电极的电压，4.6V，量电源座充的电压，4.7伏，如果把电池装上去，岂不是会充爆？

建议不要用中国之声做干扰台重复用中国之声没意义，用文艺之声之类的偏门的节目上短波做干扰台挺好，把冷门的台覆盖一下，功德无量

大家给点建议，基本型CDR数字广播收音机，你们的需求是什么？之前几乎人人都说德生那款CDR收音机的外观太丑，大大影响购买欲，现在海尔这边重新开了两款模具，大家感觉好看吗？现在做的是基本型的，就是让大家先有得用，只是满足基本的收听CDR，其它一些功能还没有做，后面会做液晶屏显示的，能显示文字，天气预报，台标，节目名称等数码信息，不过需要电台的配合发送这些数码信息，现在标准也还没出来，所以还没那么快。刚了解到，后期价格一定会降下来，不可能会这么贵，到最后，基本型收音机甚至能做到几十元的价格，只比普通收音机贵几十元，也就一百多元左右，但这都不知道要等到什么时候了，现在没有量，生产成本高，所以价格是贵了，几位爱好者能咬咬牙买下来，很感谢你们对CDR的支持。希望大家不要持悲观态度，有了海尔，华音，广科院的坚持和推动，CDR会发展起来的，节目会丰富起来的，机器价格会降下来的，功能会越来越多，特别感谢早期的体验者，支持者！对于基本型收音机和电台节目，大家都有哪些需求呢？

CDR收音机已经有两个北京的爱好者收到货了 106.1强，99.6弱点

过段时间，会有这两款CDR收音机产出价格也是488元，什么时候有货还不清楚，我一直在关注。黑色的是海尔品牌，黄色的是睿盈达品

CDR收音机有少量现货，可以买到有诚心求购的吗？过完今天就没啦，代理商报价是488，如果不是真心想买的，嫌这嫌那的，请绕道，以免搅局。有需求者请报上地区，精确到市，我查信号覆盖，不要只报个省出来，比如，“河南有信号吗？”我怎么答？河南这么大

开贴统计CDR数字广播收音机需求数量对CDR感兴趣的爱好者应该不会少，有极度发烧的，有只是好奇的，有持观望态度的…… 真正想购买CDR收音机的爱好者请在此贴留言，我统计一下需求数量。关于价格，比PL660便宜。关于节目数量，是1个频率打包3个节目，分别是老年之声，娱乐广播，乡村之声。关于信号覆盖，只收集了一部分地区的数据，详见我的另一贴，百度搜索：收集各地CDR频率和覆盖状况

#短波# 关于短波广播的未来应用设想不局限于现有播出内容、形式和接收设备，仅将短波广播定位为一种功能强大、覆盖面广、经济高效的移动媒体手段，大家希望短波广播能够实现哪些应用功能？还有哪些应用场景？请天马行空，不吝赐教

关于镍氢电池的寿命只知道可充放500次循环，但如果1年充放电1次，能用500年？
