阳离子交换容量和可交换的阳离子的测定

This week we answer the question from the student in Odence ucreen, Marisca wants to know about the program that these foreign students work in the United States during their summer vacations,the programme is cold summer work /travel,the state department in ministed for full-time college or university students who speak English well,students come all that gein one exchange reason, they can work for up to four months during their school break ,they generally working service jobs in stores,resorts,hotel,restaraunt and a miziment part.

这周我们回答了乌克兰奥德萨一个学生的问题，Marisca想要了解在美国的外国学生在暑假期间参加工作的项目问题。这个项目称之为暑期工作/旅行，州政府部门对于此项的要求是那些英语说的好的全职学院或大学的学生。学生来时通过J-One交换通行证，这样他们就可以在学校假期见最多工作四个月的时间，他们通常做一些服务业的工作，如商店，旅游胜地，宾馆，饭店以及娱乐场所。但是夏季交换旅仍是允许的。
