The stabiliazation on the ultraviolet light, the ultrasonic radialization and the oxydation of KClO3 for vitamin E and its inclusion compound by β-cyclodextrin is investigate.

用β-环糊精对V进行包络，制备了V-β-环糊精包络物，考察了V及其包络物对紫外光和超声波辐射以及KClO3氧化的稳定性。

Additionally, the term test should be used when referring to the NDT method, that is, Radiologic Testing, Ultrasonic Testing, and so forth.

此外，长期的测试时，应当使用指的是无损检测方法，也就是影像测试，超声波检测，等等。

Presently, in our country we mainly apply the manual ultrasonic to detect the locomotive wheelsets. By this way we can predict the remanent life of the wheelset to a degree.

当前，国内提速机车轮对的探伤，主要采用手工超声波探伤的方式，这种方式只能探测轮对的部分区域，而且效率低、误判率较高。

Compared to the sample without ultrasonic treatment, it was found that, for AZ31 magnesium melt alloy treated by ultrasonic, the refined grain size and the inproved distribution of grain with its shape of oval-shaped or spherical can be obtained, and the precipitation inside Al matrix was inhibited The Mg17 Al12 precipitates distributed mainly along the grain boundary and hardness was improved remarkedly.

通过对铁合金AZ31进行熔体超声处理发现，处理后试样的晶粒较未进行超声处理的试样有明显细化，分布均匀程度提高，形状呈椭圆状或球状，合金元素Al在晶粒内的析出被抑制，Mg17Al12第二相的析出主要集中于晶界，硬度有明显提高，并且通过试验确定出了最佳处理功率和时间，为超声波在铸造生产中的应用提供了依据。

With ultrasonic wave and lysozyme, the recombination N protein is split from bacteria. We dissolve it in guanidine hydrochloride, purify it with Ni〓 affinity chromatography column and renature it in vitro. By testing the antigen of the purified N protein, it shows that its activity is very high.

In this manuscript, the quality changes of the dehydrated Salicornia bigelovii Torr treated by clear water immersion, vacuum infiltration and ultrasonic treatment were inverstigated, and the quality parameters were compared on the basis of salt content, conductivity of soak solution, VC and chlorophyll contents, sensory assess before or after rehydration.

通过对含盐量、浸泡液的电导率、VC、叶绿素、干制品复水前后的感官评定分析，研究了清水浸泡、真空渗透、超声波处理等3种脱盐方式对海芦笋干制品含盐量及其品质的影响。

It was investigated how to increase the yield and purity of tannin, flavone and oligoprocyanidms from the root and stalk of sanguisorba, and the stability of polyphenols from sanguisorba was studied, too. The chemical constitutes of sanguisorba were analyzed, the conditions on extracting tannin, flavone and oligoprocyanidins from sanguisorba by general lixiviating process and ultrasonic wave were optimize. The flavone and oligoprocyanidins were separated from sanguisorba and purified. The stability of polyphenol from sanguisorba was studied and the chemical structure of the products was analyzed.
