The corporate-oriented HP EliteBook 2560p has all of the common ultraportable goodies, but its actual attraction is its excellent sturdiness. It's constructed to have a lickin' and carry on tickin' (apologies to Timex). A refresh depending on second-generation Intel Core processors, the 2560p is actually a first rate performer with some wonderful ergonomic and style flourishes. It can be somewhat stodgy-looking and hefty for an ultraportable, but that is an understandable trade-off for that ruggedness.

Constructed mainly from aluminum and magnesium, the 2560p completes its macho metal trilogy with supersturdy titanium hinges. The 2560p passes the U.S. military's MIL-STD-810G drop examination, which number of laptops even attempt. Yet another remarkable function of the 2560p--one that every vendor should consider duplicating--is the really effortless access to elements. Slide a latch again, and the single panel that covers the whole bottom from the laptop computer slides absent (it may be locked having a screw) to expose each of the main parts within. The unit is somewhat hefty for an ultraportable at virtually 4 pounds, but the additional heft lends for the system's reliable really feel.

However not the quickest ultraportable we've tested, our EliteBook 2560p examination configuration proved more than competent. Carrying a Core i5-2410M CPU, 4GB of DDR3 RAM, plus a 7200-rpm, 320GB Toshiba difficult push, the notebook delivered a score of 114 in WorldBench 6. That mark is really a minor underneath regular for your classification and configuration, but subjectively the 2560p is quite responsive.

Within our exams, gaming body prices from your built-in Intel High definition 3000 graphics ended up playable only in the extremely lowest resolutions and detail settings. Battery lifestyle utilizing the 62-watt-hour battery included with our test unit was six hours, 45 minutes--good, but nicely shy in the 8 hrs or maybe more we've seen from a few other ultraportables.

The EliteBook is offered inside a selection of flavors, ranging in the $1099 no-optical-drive price range configuration we examined to $1699 for any model with a DVD burner plus a 128GB solid-state push (prices are as of August 23, 2011). No Blu-Ray push is obtainable. A 1366-by-768-pixel, 12.5-inch display is normal on all types and offers a crisp picture with very even backlighting. Video playback is as sleek as can be, as well as the speaker sound is really good for an ultraportable, although it's got tiny while in the means of bass reaction.

Ports and connectivity are mainly up to snuff, despite the fact that USB 3.0 is absent. The company's reps explained to me that USB two.0 was all which was essential. (They are almost certainly correct--for the next 6 months.) The 2560p has four USB two.0 ports (one among that is usually powered as long as the notebook is plugged in), and also yet another in the twin eSATA/USB form, mitigating a bit the lack of USB 3.0. An additional deliberate omission is definitely an audio input jack: For audio input, the laptop relies on the dual microphones bracketing the Hi-def webcam within the display screen bezel. The ethernet link is gigabit, the built-in Wi-Fi supports both the two.4GHz and 5GHz bands, and Bluetooth is involved.

The 2560p's input ergonomics are extremely good. The keyboard is recessed into your deck much enough which you attain a cozy wrist angle along with your palms resting within the front part of explained deck. The reaction is comparatively crisp; and in contrast to many Chiclet-style designs, the keyboard has slightly concave keys to promote assured finger placement. The touchpad, with its two sets of buttons (over for use when typing, and under for two-handed cursoring), gives wonderful reaction. Staying ready to double-tap within the upper-left corner to permit or disable it is just a neat touch, too.

HP's preinstalled applets are remarkably helpful, although any person acquainted with Windows can skip several of them. HP's ProtectTools now incorporates a cleaner interface and provides drive encryption, finger-swipe biometrics, and facial recognition with Bluetooth confirmation. You will also discover a good electrical power utility which will even handle some external monitors--if they occur for being HP versions. The running technique is Windows 7 Professional.

In case you want an ultraportable notebook that you simply can be self-assured will stand up to a few a long time of large use, the HP EliteBook 2560p deserves a seem. A three-year warranty and on-site service are available to offer extra peacefulness.

 

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。
