          今天在电台里听见了这首歌,很美,似乎唤起了一种很久远的情愫,就是想不起来在哪里听见过,记忆中好像是一个欧美大片里的歌,难道是《美女与野兽》,索性搜索了一下,找到了,但不是一个电影里的歌,是魔兽世界的宣传片里的主题歌(席琳.迪翁演唱),上次我一个同学给我听过,难怪这么熟悉啦。因为不能嵌入我blog,只能去搜来听听吧。   

A new day...

 A new day...

I was waiting for so long
For a miracle to come
Everyone told me to be strong
Hold on and don't shed a tear
Through the darkness and good times
I knew I'd make it through
And the world thought I had it all
But I was waiting for you
Hush, love
I see a light in the sky
Oh, it's almost blinding me
I can't believe
I've been touched by an angel with love
Let the rain come down and wash away my tears
Let it fill my soul and drown my fears
Let it shatter the walls for a new, new sun
A new day has... come
Where it was dark now there's light
Where there was pain now there's joy
Where there was weakness, I found my strength
All in the eyes of a boy
Hush, love
I see a light in the sky
Oh, it's almost blinding me
I can't believe
I've been touched by an angel with love
Let the rain come down and wash away my tears
Let it fill my soul and drown my fears
Let it shatter the walls for a new, new sun
A new day has... come
A new day has... come
Let the rain come down and wash away my tears
Let it fill my soul and drown my fears
Let it shatter the walls for a new, new sun
A new day has... come
A new day has... come
Ohhh, a light
Hush, now
I see a light in your eyes
All in the eyes of the boy
I can't believe
I've been touched by an angel with love
I can't believe
I've been touched by an angel with love
Hush, now
Hush, now

           希望如歌中唱到的,我们会变的更加坚强,期待新的每一天.......

内容概要:该研究通过在黑龙江省某示范村进行24小时实地测试,比较了燃煤炉具与自动/手动进料生物质炉具的污染物排放特征。结果显示,生物质炉具相比燃煤炉具显著降低了PM2.5、CO和SO2的排放(自动进料分别降低41.2%、54.3%、40.0%;手动进料降低35.3%、22.1%、20.0%),但NOx排放未降低甚至有所增加。研究还发现,经济性和便利性是影响生物质炉具推广的重要因素。该研究不仅提供了实际排放数据支持,还通过Python代码详细复现了排放特征比较、减排效果计算和结果可视化,进一步探讨了燃料性质、动态排放特征、碳平衡计算以及政策建议。 适合人群:从事环境科学研究的学者、政府环保部门工作人员、能源政策制定者、关注农村能源转型的社会人士。 使用场景及目标:①评估生物质炉具在农村地区的推广潜力;②为政策制定者提供科学依据,优化补贴政策;③帮助研究人员深入了解生物质炉具的排放特征和技术改进方向;④为企业研发更高效的生物质炉具提供参考。 其他说明:该研究通过大量数据分析和模拟,揭示了生物质炉具在实际应用中的优点和挑战,特别是NOx排放增加的问题。研究还提出了多项具体的技术改进方向和政策建议,如优化进料方式、提高热效率、建设本地颗粒厂等,为生物质炉具的广泛推广提供了可行路径。此外,研究还开发了一个智能政策建议生成系统,可以根据不同地区的特征定制化生成政策建议,为农村能源转型提供了有力支持。
We are given a log file that contains a sequence of events related to an update process on a device. The log is from the perspective of an automated test system (autotest) that is monitoring the update process. The key events in the log: 1. The test system is trying to establish an SSH connection to the device at 192.168.231.225. Initially, the connection is down, so it tries to start a new connection. 2. At 04:38:48, there's a timeout error waiting for the main SSH connection to come up. 3. Then, at 04:39:06, we see that the device has switched slots (likely due to an update) and the test breaks out of a waiting loop. 4. The test then checks the status of the update engine by running `update_engine_client --status` via SSH. The output shows that the update is in the DOWNLOADING state with progress at about 13%. 5. The test then retrieves the update_engine log and we see the log entries from the device's update_engine daemon. The update_engine log shows: - The update_engine starts at 04:39:01. - It identifies that the device is booted from slot A (slot 0). - It's an unofficial build, so periodic update checks are blocked. - It begins an update for a DLC (Downloadable Content) called "timeofday-dlc". The download URL is provided, and the download completes successfully (HTTP 200) at 04:39:05, with 23064576 bytes downloaded. - After verifying the hash, the DLC is mirrored and set to Active. - Then, the update_engine starts another update for a different DLC: "ml-dlc-a97333ed-3157-49a3-b503-2d2d3f23c81d". The log shows the installation starting for this DLC. However, the test then fails because it cannot find the update_engine logs to verify the update. The last lines in the log are: ``` 06/05 04:39:09.952 DEBUG| test:0439| Test failed due to update_engine logs are missing. Cannot verify update.. Exception log follows the after_iteration_hooks. ``` This indicates that the test expected to find update_engine logs for the entire update process, but at the time it checked (04:39:09), the log for the second DLC update was not available (or the test looked in the wrong place). But note: the test did retrieve the update_engine log at 04:39:09.856 (the file `update_engine.20250604-213901`). However, that log only covers the first DLC (timeofday-dlc) and the beginning of the second DLC (ml-dlc). The second DLC update was still in progress when the test checked. The test then, at 04:39:09.920, runs `ls -t -1 /var/log/update_engine/` and gets only one log file: `update_engine.20250604-213901`. This is the same log that was previously retrieved. The test then fails because it expects to see logs for the entire update (which might include multiple log files or a more recent one) but only one is present. It's possible that the update_engine daemon rotates logs and the test expects a new log for the second update? However, the log we see spans from 04:39:01 to 04:39:07 (and beyond, but the test only retrieved up to 04:39:09.913 in the log). The test failure message says "update_engine logs are missing", meaning it couldn't find the logs it expected. Alternatively, the test might be looking for a log entry that confirms the entire update (including the second DLC) completed, but the log we have only shows the start of the second DLC update. Given the information, the problem appears to be that the test is failing because it cannot find the expected update_engine logs to verify the update. This could be because: - The test is not waiting long enough for the update to complete and the logs to be written. - The update_engine log rotation might have occurred and the test is not accounting for the latest log file. - The test expects a specific log entry that is not present in the retrieved log. However, from the provided log, we can see that the update_engine was in the middle of updating the second DLC when the test checked. The test then immediately tried to get the logs again and found only one log file, which it had already retrieved. The test code seems to be in a state where it breaks out of the waiting loop because it detected a slot switch (which happened for the first DLC) but then it tries to verify the entire update (which includes multiple DLCs) and fails because the second DLC update was still ongoing and the logs were not complete. In summary, the issue is that the test did not wait for the entire update (all DLCs) to complete before attempting to verify the logs. It only waited for the first DLC to complete and the slot switch, but then proceeded to check the logs while the second DLC update was still in progress. Recommendation: The test should wait until the update_engine status indicates that the update is fully completed (e.g., IDLE) and then verify the logs. 翻译成中文
