云南省马铃薯储存现状、存在问题及解决策略

近年来，云南省马铃薯产业发展较快，但马铃薯的储存远滞后于产业发展的要求。收获中块茎的机械损伤，储存基础设施、储存方式的落后和储存技术的缺乏，造成马铃薯在储存过程中，块茎过早发芽，失水后重量迅速减少，病虫害发生严重等问题，导致马铃薯商品薯品质和种薯质量降低，农民收入减少。本文在对云南省马铃薯储存现状、储存方式、储存过程中造成损失的原因等调查的基础上。提出了相应的解决对策。

医院药品储藏保管的现状及分析

药品具有其特殊性和高质量性特点,科学地储存和保管药品,才能保证药品的有效性和治疗的安全性.如不按规定储存和保管,即使在有效期内药品效能也会逐渐下降,疗效逐渐丧失,甚至会产生毒性.笔者结合在西药库工作多年体会,对医院药品的储存现状作如下总结：光线、空气、温湿度是影响药品质量最主要的3要素.

Non-destructive Testing Robots （NDTBOTs） for In-Service Storage Tank Inspection

Petrochemical storage tanks are generally inspected when the tank is offline mostly to assess the extent of underside corrosion on the tank floor. Emptying, cleaning and opening a tank for inspection take many months and are very expensive. Inspection costs can be reduced significantly by inserting robots through manholes on the tank roof to pertbrm non-destructive testing （NDT）. The challenge is to develop robots that can operate safely in explosive and hazardous environments and measure the thickness of floor plates using ultrasound sensors. This paper reports on the development of a small and inexpensive prototype robot （NDTBOT） which is designed to be intrinsically safe for zone zero operation. The robot ＂hops＂ across the floor to make measurements, without any external moving parts. The paper describes the design, experimental testing of the NDTBOT and presents results of steel plate thickness measurements made under water.
