C
Most environmental pollution on Earth comes from humans and their inventions, such as cars or plastic. Today, car emissions (排放物)are a major source of air pollution leading to climate change, and plastics fill our ocean, creating a significant health issue for marine (海洋的) animals.
And what about the electric light, thought to be one of the greatest human inventions of all time Electric light can be a beautiful thing, guiding us home when the sun goes down, keeping us safe and making our homes bright. However, like carbon dioxide (CO2) emissions (排放) and plastic, too much of a good thing has started to impact the environment. Light pollution, the improper use of outdoor light, is affecting human health, wildlife behavior and our ability to observe stars.
Light pollution is a global issue. This became obvious when the World Atlas of Artificial Night
Sky Brightness, a computer-generated map based on thousands of satellite (卫星) photos, was published in 2016. Available online for viewing, the map shows how and where our globe is lit up at night. Most areas of North America, Europe, the Middle East and Asia are glowing (发光) with light, while only the furthest regions on Earth (Greenland, Central African Republic and Niue) are in total darkness. Some of the most light-polluted countries in the world are Singapore, Qatar, and Kuwait.
Sky glow (人工白昼现象) is the brightening of the night sky, mostly over cities, due to the electric lights of cars, street lamps, offices, factories, outdoor advertising, and buildings, turning night into day for people who work and play long after sunset.
People living in cities with high levels of sky glow have a rough time seeing more than a handful of (少数) stars at night. Astronomers (天文学家) are particularly concerned (担心) with sky glow pollution as it reduces their ability to view (观察) stars.

(2)加入电场后,沿x轴方向左右调节探测屏,求粒子打在探测屏上的点到探测屏圆心P的最远距离D;
(3)加入电场后,沿x轴方向左右调节探测屏,若要使粒子恰好打在探测屏的圆心P上,求此时P点与粒子源间的距离d。
2.★★★★(2024湖南,14,14分)如图,有一内半径为2r、长为L的圆筒,左右端面圆心O'、O处各开有一小孔。以O为坐标原点,取O'O方向为x轴正方向建立xyz坐标系。在筒内x≤0区域有一匀强磁场,磁感应强度大小为B,方向沿x轴正方向;筒外x≥0区域有一匀强电场,场强大小为E,方向沿y轴正方向。一电子枪在O'处向圆筒内多个方向发射电子,电子初速度方向均在xOy平面内,且在x轴正方向的分速度大小均为v0。已知电子的质量为m、电荷量为e,设电子始终未与筒壁碰撞,不计电子之间的相互作用及电子的重力。
(1)若所有电子均能经过O进入电场,求磁感应强度B的最小值;
(2)取(1)问中最小的磁感应强度B,若进入磁场中电子的速度方向与x轴正方向最大夹角为θ,求tan θ的绝对值;
(3)取(1)问中最小的磁感应强度B,求电子在电场中运动时y轴正方向的最大位移。
3.★★★★(2024届贵州贵阳清华中学考前预测)现代科技中常常利用电场和磁场来控制带电粒子的运动,某控制装置如图所示,区域Ⅰ是圆弧形均匀辐向电场,半径为R的中心线O'O处的电场强度大小处处相等,且大小为E1,方向指向圆心O1;在空间坐标系Oxyz中,区域Ⅱ是棱长为L的正方体空间,该空间内充满沿y轴正方向的匀强电场E2(大小未知);区域Ⅲ也是棱长为L的正方体空间,空间内充满平行于xOy平面,与x轴负方向成45°角的匀强磁场,磁感应强度大小为B,在区域Ⅲ的上表面是一粒子收集板;一群比荷不同的带正电粒子以不同的速率先后从O'沿切线方向进入辐向电场,所有粒子都能通过辐向电场从坐标原点O沿x轴正方向进入区域Ⅱ,不计带电粒子所受重力和粒子间的相互作用。
