离bpho物理竞赛时间还有多久?R1一般在11月底

放眼下半年的国际竞赛，bpho物理竞赛是需要重点关注的一个，毕竟它的出题特点和牛剑笔面试也有关联度。本文就来介绍一下这项赛事的报名、考试时间，大家注意规划好自己的复习节奏啦。

bpho物理竞赛考查范围

BPHO的组委会主要由牛津大学、英国物理学会和Odgen基金会组成。

这项赛事需要掌握A-level全部物理知识点，有一些考点超出A-level考纲，属于大学物理专业入门知识（例如AS电路，电场，动量，数据分析和核物理等；A2阶段课本里的圆周运动，磁场，光电效应，量子力学，简谐运动，热力学）

如果你参加的是BPhO-AS 组别，它的知识点范围不会像AS那么广，但会更深一点，非常考验在题目中寻找提示的能力。

【2018BPHO物理竞赛ROUND 1真题举例↓】

a)

Two uncharged capacitors with values C1 and C2, are connected in series with a battery of e.m.f. V , and a switch. When the switch is closed there is a charge of Q1 and Q2 on the capacitors respectively

(i)  State the relationship between Q1 and Q2.

(ii)  State expressions for the potential differences across each capacitor, V1 and V2

(iii)  Hence derive an expression for the equivalent capacitance, Ceq produced by C1 and C2 in series.

(iv)  Write down expressions for the total energy stored in the two capacitors, and the energy supplied by the battery, in terms of Ceq and V , and comment on the difference

(6)

b) A 15 nF parallel plate capacitor is connected across a 70 V battery, as in Figure 11. How much

work must be done in order to double the plate separation

(i) with the battery disconnected, 

(ii) with the battery connected?

c)

(i) Two capacitors, of capacitance 2.0 μ F and 4.0 μ F, are each given a charge of 120 μ C. The positive sides are then connected, as are the negative sides. Calculate:

i. The new potential difference across the plates. ii. The change in the energy stored.

(ii) A conducting metal sphere is insulated from the ground. It is initially charged by contact with a small metal disc which carries a charge q, so that the sphere gains charge Q. The metal disc is then again given a charge q, and is then touched on the sphere a second time. If this process is repeated indefinitely, what would be the final charge on the sphere, Qf ?

bpho物理竞赛时间

以去年为例，考试时间为2021年11月13日

R1报名截止时间: 2021 年 11 月 03 日

R2报名截止时间: 2022 年 03 月

当然BPHO是一个组别很多的比赛，不全部集中在年底，下半年的赛程可以参考下这张表↓

bpho物理竞赛报名方法

主要有2种方法，一种是通过自己的学校报名，另一种就是去阿斯丹网站报名啦。

作为一项能给背提加分的国际竞赛，BPHO还是有一点难度的，要求同学数量掌握求导、积分运算和求解常微分方程等知识点，因此有计划参赛的话，训练是必不可少的。有需要的话可以点击这里预约试听【橡沐BPHO课程班】——
