应该限制通过高价购买设备来验证一些理论的基础研究（实验研究）已有7人参与
|
|||
| 论坛上smilerobin说得很好“很多高精尖的设备应该自己研制，不能靠购买尖端仪器测试，最典型的莫过于验证弦理论的粒子碰撞机，耗费几千亿，却毫无应用前景。”我们当前还是发展中国家，不是发达国家。这种纯烧钱的基础研究应该是发达国家的责任。 |

唉，没办法，生物实验更严重啊，试剂耗材到仪器全是进口的。不过说实话，进口的质量确实是好，举个例子，我用国产的DMSO溶解一个药物，放置在4℃冰箱药物析出来，就再溶解不了了，用进口的DMSO就不会出现析出不溶的问题，肯定是DMSO的纯度的问题，唉，没办法！ 发自小木虫Android客户端 |

这些仪器国产也是有的，质量还是比不上进口的，没办法！现在国际疫情的原因，订进口试剂耗材周期长了很多，我们也不想用进口的啊，是真贵，我们想用国产的，又不敢乱用，怕出不来结果，唉，没办法！ 发自小木虫Android客户端 |
