    　　篮球记者 Jeremy Brener 近日撰文，复盘了猛龙前锋斯科蒂-巴恩斯上赛季的赛场综合表现，并给出专业评价。

    　　记者指出，对比前一赛季，巴恩斯常规赛场均得分从 19.3 分小幅下滑至 18.1 分，看似进攻端产出略有收缩，但他在防守层面的进步肉眼可见。

B |     While scientists and science fiction authors alike have long dreamed of sending crewed missions to Mars, a new study suggests these plans may hit a snag – a big one.,The authors of a yet to be peer-reviewed study argue that the participants of such a mission to Mars would end up being exposed to radiation – namely, to “energetic charged particles from Galactic and Solar origin” – both while in transit and while on the planet itself, with the “thin spacecraft shield” and “rarefied Martian atmosphere” offering little in the way of protection.,The research team attempted to gauge the impact of a simulated 1,000-day mission to Mars on various organs of the human body, and concluded that astronauts may be exposed to radiation doses above one Sievert, which is over the safe limit set by most space agencies, New Scientist points out.,“We suggest mitigation strategies such as improved ways of shielding and dietary supplements, and make recommendations for the safety of astronauts in future crewed missions to Mars,” the team wrote in the abstract of their work available on the arXiv preprint server.,Ideas about how astronauts may be protected from radiation during a mission to Mars have already been proposed, such as the concept of a radiation shield comprised of a fungus found growing at the Chernobyl Nuclear Power Plant.,Last year, one architecture studio even unveiled a project for a self-sufficient and sustainable city that would be built on the red planet itself.。上赛季他一路冲到最佳防守球员评选第五名，同时入选最佳防守二阵，抢断、盖帽总数跻身联盟前列，能灵活换防场上全部五个位置，撑起猛龙整套防守体系。

    　　Jeremy Brener 表示，正是这份肉眼可见的防守统治力，让他认定巴恩斯完全有能力成为一支冲冠强队的核心球员。不过他也客观点出巴恩斯现存短板：外线三分投射稳定性不足，想要真正跻身联盟顶级巨星行列，还需要持续打磨远投手感。
