指示剂

In the validation of the sterilization of equipment and of transfer systems, Biological Indicators, as well as temperature sensors Thermocouple (TC or Resistance Thermal Device should be strategically located in cold spots where condensate may accumulate. These include the point of steam injection and steam discharge, as well as cold spots, which are usually low spots.

在设备和传递系统的灭菌验证中，生物指示剂和温度传感器（热电偶或者电阻温度装置）应放在冷凝物积聚的冷点上，包括蒸汽的入口和出口点，和那些通常温度比较低的点。

In order to study on the fast,simple and efficacious method of forecast the sclerotinia stem rot.

为了探索预测油菜菌核病发生情况的快速、简单、有效的方法；此研究采用检测被核盘菌子囊孢子感染的油菜花瓣数量来预测预报菌核病可能发生严重度程度，实验采用添加了两种不同pH指示剂的改良型Steadman's培养基在室温下培养在油菜花期(3月下旬～4月中旬)每天采自2块试验田的新鲜花瓣，如果花瓣被病原菌子囊孢子感染，接种培养后培养基颜色发生改变，统计被感染的花瓣数；结果表明：除1天在一块田没有检测到被子囊孢子感染的花瓣外，油菜整个花期都有被感染的花瓣出现，但初花期被感染的花瓣较少，而盛花期和终花期被感染的花瓣较多，第一块田被感染的花瓣数在两种培养基上出现的百分率分别为32.0%和40.2%，第二块田分别为27.3%和35.7%。
