这是一个真实的故事。当年,我们所以为的那个作弊者如今已是物理领域颇有成就报道人。多年以来,高中时我做的那件事始终深藏在我心底,直到看到他的消息,我才终于明白自己真的错了。嫉妒和自以为是很可怕,但对这些毫不自知却更加可怕。

A procedure for purification of single walled carbon nanotubes(SWNTs) grown by the chemical vapour deposition(CVD) of carbon monooxide has been developed. Based on the result from TGA/DTA of as prepared sample, the oxidation temperature was determined. The process included sonication, oxidation and acid washing steps. The purity and yield after purification were determined and estimated by TEM. Moreover, for the first time, a loop structure for CVD SWNTs has been observed.

AIM:To report the outcomes of patients undergoing anterior segment optical coherence tomography-guided transepithelial phototherapeutic keratectomy(ASOCT T-PTK)for central corneal scarring after pterygium ***:The charts of 11 eyes of 10 patients that underwent ASOCT T-PTK following excision of visual axisinvolving pterygia were retrospectively reviewed from a single private practice *** visual outcomes and corneal topographic findings were evaluated 4±1 mo after pterygium excision and 6±2 mo after transepithelial phototherapeutic keratectomy(T-PTK).RESULTS:All 11 eyes tolerated both the pterygium excision and T-PTK procedure well without any significant intraoperative or postoperative *** distance visual acuity(UDVA)and manifest refraction corrected distance visual acuity(CDVA)improved after pterygium excision(P=0.03 and P=0.05,respectively).The UDVA and CDVA improved further after T-PTK(P=0.004 and P=0.002,respectively).The topographic surface asymmetry index,topographic surface regularity index,and topographic projected visual acuity significantly improved after T-PTK(P=0.0092,P=0.0022,and P=0.0002,respectively).None of the subjects lost any lines of CDVA,developed recurrence of pterygia or required keratoplasty during the postoperative ***:ASOCT T-PTK can provide excellent visual and anatomic outcomes in patients with central corneal scarring after excision of visual axis-involving pterygia.

吸取他人成功的经验和借鉴别人失败的教训 ,对石油工业尤为重要。以如何运用类比为话题 ,对 6个国家 2 1家石油公司与地球科学家、油藏工程师和勘探开发经理们进行了广泛的采访和调研 ,获得了有关类比的应用范围、类比资料的来源、应用类比的过程以及如何避免滥用类比等方面的宝贵的第一手材料。其中两项主要结果是 :① 2 /3被采访的石油公司认为在全球范围内“撒网”类比 ,来寻找高质量的油气田 ,对降低勘探风险和优化油田开发决策至关重要 ;只有不到 1/3的公司在勘探评价和选定开发方案时只参考其工作区附近的油气井、油气藏或油气田资料。②尽管地震资料常常被作为决策的决定性信息 ,但绝大部分地质师和油藏工程师认为 ,是类比油气田为他们提供了成功进行勘探开发所需要的详细资料和思路 ,并且帮助他们加深了对关键参数的理解。调研结果显示 :高质量的类比确实有助于降低勘探风险。
