试题总评:2013年卓越大学联盟自主招生物理试题覆盖了高中物理必修一、必修二、选修3-1、选修3—2、选修3—4、选修3—5,多数试题难度与高考相当,个别试题综合性强,能力要求较高。1._(27)~(60)Co的衰变方程可以写成器_(27)~(60)Co→_Z~(60)Ni+_1~0e+γ_e,其中γ_e是反电子中微子,反电子中微子不带电,质量可视为零。由衰变方程可知Z=____。如果静止的_(27)~(60)Co发生衰变,实验过程中测量衰变产物中_(Z)~(60)Ni和_(-1)~0e的径迹时,由____守恒定律可知,_(Z)~(60)Ni和_(-1)~0e的
Test Questions Overall: In 2013, the University Admissions Physics Examination covered the high school physics compulsory one, compulsory two, elective 3-1, elective 3-2, elective 3-4, elective 3-5, most of the difficulty of the exam and the college entrance examination fairly, individually Comprehensive examination questions, ability requirements higher. The decay equation of 1. - (27) ~ (60) Co can be written as follows: Co → _Z ~ (60) Ni + _1 ~ 0e + γ_e, where γ_e is the counter electron neutrino, Electron neutrinos do not charge, the quality can be regarded as zero. The decay equation shows that Z = ____. If stationary (27) ~ (60) Co decays and the traces of _ (Z) ~ (60) Ni and _ (-1) ~ 0e in the decay products are measured during the experiment, the conservation law of ____ It can be seen that _ (Z) ~ (60) Ni and _ (- 1) ~ 0e
