2、In the quantum theory, which of the following tells us that the predictions of quantum mechanics must pass smoothly into those of classical mechanics whenever we progress in a continuous way from the microscopic to the macroscopic?
(A) Correspendence principle
(B) Uncertainty principle
(C) Probability distribution
(D) Probability density theory
(E) Electronic configuration theory
阅读没学好,题目是什么意思?选项各是什么意思?
1 If the chiral carbons all have the same stereochemistry (all R or all S), the polymer is called isotatic. If the stereochemistry varies, the polymer is atatic.
2 下边哪个选项告诉我们在从微观到宏观的连续推导中,量子理论的预测结果必须与经典理论结果相一致?
A 一致性原理,玻尔提出在数量较大的情况下,量子学将转变为经典物理。
3 糜蛋白酶 Chymotrypsin
为由胰脏中分离制得的另一种蛋白酶,可溶于水及生理盐水中。在固体状态时比较稳定,故在临用前溶解供用。
白色或类白色结晶或无定形粉末,无臭,易溶于水。pH7~8活性最强。水溶液易失活,以pH3~4水溶液最稳定。
能迅速分解蛋白质
