密集度试验分组与不分组两种做法,一直就并行于常规兵器试验之中。全国所有的弹炮厂,对密集度试验(也称为精度校验),都是不分组的。国家试验基地,对密集度试验,一般是采用分组的,但是这种试验经常与射程试验结合在一起,很少是单纯的密集度试验。所以这两种方法,各自都有近三十年的实践。而不分组做法的实践,较之于分组做法多得多。 Intensity test grouping and un-grouping two practices, has been parallel to the conventional weapons test. All the country’s artillery gun factory, on the intensity test (also known as precision calibration), are not grouped. National test sites, for intensity tests, are generally grouped, but oftentimes this test is combined with range tests, which are rarely purely intensity tests. So these two methods each have nearly thirty years of practice. The practice of grouping practices is much more than the practice of grouping.
