Institute of Plant Protection, Anhui Academy of Agricultural Science, Hefei 230031, China Abstract: The control effect of propiconazole microcapsule to postharvest anthracnose of apple and their application techniques at 25℃ and 10℃ in storage were studied. The results showed that the difference between the control effect with spraying and soaking were significant, the control effect of fast release for propiconazole microcapsule was better than that of slow release. The control effect of fast release for propiconazole microcapsule was 100% at 25℃ in storage, and was 86.8% 10℃ in storage.

Because the fish drying Shrinkage small Shrinkage crack surfaces, more in Water, so the bibulous rate of early (see figure 4) soon, absorbing ability, 1.2 m in bibulous rate (Water absorption Measurement can reach 1 36), In the early EHD water are slower, bibulous rate in 30 m in later, when the water absorption speed enough time to also can achieve higher bibulous rate and natural drying EHD with dry bibulous rate basic same, in addition, natural drying and EHD dry fish good water resistance, 120 m in water can still keep complete shape after drying fish, but by 120 m in pieces after absorbing began.

由于热风干燥鱼的收缩率较小、表面有较多缝隙，所以在吸水初期的吸水速度很快(见图4)，吸水能力很强， 120 m in 吸水率可达到1。 36； EHD在吸水初期的吸水速度均较慢，在30 m in以后吸水速度加快，当吸水时间足够时也能达到较高的吸水率，自然干燥与EHD干燥的吸水率基本相同，另外，自然干燥和EHD干燥鱼的耐水性好， 120 m in 吸水后仍能保持完整形状，而热风干燥鱼经120 m in 吸水后即开始溃散。

The agglomerations sizes of fine particles in the fluidized bed are smaller under higher SPL. The sound waves have little effect on the agglomerations when it is under 120dB. But the agglomerations sizes will be dramatically reduced to 180μm from 720μm when the SPL is above 130dB. The umf has a minimum value at an appropriate frequency of sound and a good quality of fluidization can exist in a greater ranges of frequency of sound when the SPL is higher.

当频率高于120Hz，流化床中形成聚团尺寸随着频率的增加而增大，最小流化速度也随着频率的增加而增大，当频率低于120Hz，流化床中形成聚团尺寸随着频率的减小而增大，最小流化速度也随着频率的减小而增大；料层越高，声波的衰减越大，超细颗粒的流化效果越差，最小流化速度越大。

The minimum fluidization velocity has a minimum value when the frequency of sound waves is 120Hz and it will decrease as the sound pressure level increases. The degree of sound attenuation will increase while bed material is higher and the fluidization quality of fine particles will become poor and the minimum fluidization velocity will increase. Compared with TiO2, the SiO2 fine particles have a better quality of fluidization at the same fluidized conditions.The cluster/subcluster model and oscillators model are used to describe the fluidization characteristics of fine particles in a sound-assisted fluidized bed. The theoretical calculations show that the minimum fluidization velocity umf is decreased with the SPL increased at the same frequency of sound and the quality of fluidization is better.

论文还系统的考察了声压和频率对纳米SiO2和TiO2颗粒流化特性的影响，结果表明：在频率一定的情况下，声压越高，流化床中形成的聚团尺寸越小，最小流化速度越低，流化质量越好；当声压低于120dB时，声场对超细颗粒流化特性的影响减小，当声压大于130dB时，则能显著改善流化效果，使流化床内的颗粒聚团明显减小，最小流化速度明显降低，粉体带出减小；声压一定，频率为120Hz左右时，最小流化速度最低，此时流化床中形成的聚团尺寸最小，流化效果最好；超细颗粒达到较好的流化状态存在一个最佳频率范围，随着声压增高，这个频率范围将增大。

By use of titration analysis, the thesis investigated various factors such as isocyanate, PE molecular weight, reacting substance molecular ratio, reacting temperature and time etc. influencing upon prepolymerization step. It was found that 2, 4-tolulene diisocyanate and 4, 4'diphenylmethane diisocyanate is more rapidly reacted with PE600 than HDI. With PE molecular weight increasing, the reacting temperature or time should be raised or extended relevantly. Thus PE2000+2HDI pre-polymerization should be better carried out under some catalyst, for example, Triethylene diamine , Dibutyltin dilaurate and Tin octoate were used.

首先采用滴定分析方法对WRPU预聚反应的影响因素进行了研究：芳香族二异氰酸酯TDI、MDI比脂肪族二异氰酸酯HDI反应活性高，其中TDI在反应初始阶段的反应速率比MDI快，不过随着反应的进行，MDI比TDI反应速率加快，这主要是因为TDI分子中的两个-NCO反应活性差异大所致；二元醇分子量越大，反应速度越慢；聚醚二元醇比聚酯二元醇的反应速度快；当分子量超过2000的二元醇与HDI进行预聚反应时，需借助适当的催化剂来加快反应速度，从而使预聚反应能够顺利进行，分别选择DABCO、TOA和DBDTL三种催化剂进行催化反应，发现不同的催化剂，其催化效果相差较大。

Due to the limitation and constraint on the tachymeter scale mentioned above which makes tachymetre measurements works and valid only for certain range of speed, so in order to calculate and measure slower speeds or higher speed, user can decrease or increase the unit of measurement (eg change to half-miles or half-kilometers, or ten miles or ten kilometres).

由于限制和约束就tachymeter规模，上述这使得tachymetre测量工程，并只适用于一定范围内的速度，因此，为了计算和测量速度慢或更高的速度，用户可以增加或减少的测量单位（如改变半英里或半公里，或10英里或10公里）。
