The results showed that all of the four preservatives can prevent the growth of bacteroidal soft rot, and the effect of sodium diacetate was the best. After 40 or 45 days' storage, all of the untreated asparagus were rotting, but the incidence of disease of the asparagus treated with 1.5% sodium diacetate was 0 and 32% respectively. 0.5% Zhongshengjunsu, 1.5% sodium diacetate and 1% sodium chloride can delay the reduce of chlorophyll.

结果表明，4种防腐保鲜液浸蘸笋尖均可明显地抑制贮藏过程中芦笋软腐病的发生，但以双乙酸钠处理效果最好，贮藏至40d\45d，对照已全部发病，而用1.5%双乙酸钠处理的，发病率为0和32%。0.5%中生菌素、1.5%的双乙酸钠和1%氯化钠处理，均有延缓芦笋叶绿素分解的作用。

不同杀菌剂处理的结果表明，使百功防腐效果最好；1／2的大气压减压贮藏效果显著好于冷藏；GA与1-MCP处理相比，GA处理对冬枣保鲜效果好于1-MCP。

The layers can increase obviously the destiny of microstructure, magnetic properties Br, Hcb, m and compressive strength of the NPMC bonded by plastic. The epoxy coating can improve effectively the corrosion resistance of the NPMC and delay the rust of NdFeB particles, especially the pycno-film of the cathodal electrophoresis epoxy resin plays a dominant role in the achievements. The investigation of the temperature stability of the NPMC bonded by plastic, whose NdFeB magnetic particles are NFZ-1 and Nd〓Fe〓B/α-Fe,〓 made in China, shows that their ergo-temperatures vary with their components.

Iii. Process Water cont'd Type 3 Water - Purified Water (e.g., USP Purified Water), in Europe the EMEA refers to this a Highly Purified Water - Most difficult to control microbial levels, because no preservative chlorine is present in the water -Less expensive to produce than Water for Injection Type 4 Water - The most critical quality level -Commonly used in final formulation for parenteral applications -Must satisfy the Water for Injection specification as laid out in compendia such as the USP iii.
