文档介绍:several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measuremen花钱选购高档、精细、时令蔬菜,但亦有约20%的消费者只需便宜的大路菜。
(3)蔬菜消费具有地域差异。我国南北跨度大,自然生态条件大不相同,而各种蔬菜对环境条件要求亦不一样,大体可分为喜温、喜冷凉和耐寒三类:喜温蔬菜:番茄、黄瓜、豆类等;喜冷凉蔬菜:白菜、甘蓝、萝卜等;耐寒蔬菜:大葱、蒜、菠菜等。
由于上类蔬菜品种生产的地区不平衡,导致蔬菜消费具有地域差异:
一是北方的XX、、XX等地白菜、西红柿、黄瓜、大葱、豆角五种占比重较大,白菜最大;

Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured
