Proton is , in turn , made up of two up quarks and one down quark . neutron is made up of two down quarks and one up quark 质子的内部是三粒夸克：两粒上夸克和一粒下夸克uud中子的内部也是三粒夸克：一粒上夸克和两粒下夸克udd 。
Beat the quark until creamy and smooth . add the rest of the filling ingredients and beat until very smooth . gradually pour into the crust 打化乳酪后，加入砂糖搅拌，然后加入其它配料，搅拌完全均匀。将其慢慢倒入备好的蛋糕胚里。
In large bowl , beat quark with electric mixer for 2 minutes or until smooth . add eggs , sour cream , and lemon juice ; beat 2 - 3 minutes or until creamy 用电动搅拌把德国乳酪搅打2分钟直到匀滑，加入鸡蛋，酸奶油和柠檬汁搅打2 - 3分钟。
To study the formation of a quark gluon plasma , it is of crucial importance to undeistand in detail the collision dynamics 在高能重离子对撞实验( rhic及lhc )探索夸克胶子等离子体( qgp )的过程中，对碰撞动力学的详细了解是至关重要的。
Atoms , after all , are made of electrons and nuclei , nuclei are agglomerations of protons and neutrons , and those in turn are composed of quarks 毕竟原子是由电子与原子核所组成，原子核又是质子与中子构成，而质子与中子又由夸克所构成。
