As to the type study, classification was adopted from different latitude. According to the different representation of spontaneous music, the behavior was classified into spontaneous singing, spontaneous body movement and spontaneous odyssey of the rhythm. According to different form of spontaneous music behavior, it can be classified into unceremonious spontaneous music behavior and formless spontaneous music behavior In the feature study, pleasantness, the unity of children's feeling, changing accord to the circumstances and suddenly occurring were adopted.

在对幼儿自发音乐行为的类型划分部分，研究者从不同纬度将幼儿自发音乐行为分别进行了划分：根据自发音乐行为的不同音乐表现方式，可以分为自发哼唱、自发身体舞动和自发性节奏探索；根据自发音乐行为的不同呈现形式，可以分为定形的自发音乐行为和不定形的自发音乐行为。

Trichogramma showed high control efficacy on cotton bollworm eggs after three times of release both in the second and in the third generation bollworm periods. The parasitism on the second and third generation bollworm eggs were 66.0%-70.7% and 76.0%-81.2%, respectively, which were significantly higher than that in the control (second generation: 7.0%-12.3%, third generation: 5.2%-7.4%). And the injury rate of cotton buds and bolls in the second and third generation bollworm were 2.2% and 3.1%, respectively, which were significantly lower than that in the control (second generation:8.5%, third generation: 20.9%). In the second generation bollworm period, number of bollworm eggs or larvae in the Trichogramma released cotton field did not differ to that in the chemically controlled field. But in the third generation, there were significantly less bollworm eggs and larvae in the Trichogramma released cotton field. There were more predators in the Trichogramma released cotton field. These results indicated that cotton boll worm in the transgenic insect-resistant cotton field can he effectively controlled by mass-releasing of T.

结果发现：棉铃虫卵在棉株不同部位的分布差异较大，2代棉铃虫卵主要分布在叶正面、叶背面和茎尖，3代棉铃虫卵主要分布于蕾铃；在放蜂田，赤眼蜂对棉株不同部位棉铃虫卵的寄生率差异较大，2，3代棉铃虫时期对叶正面、叫背面、茎尖、蕾铃的棉铃虫卵寄生率均较高，对叶柄和茎杆处卵的寄生率较低；并以3代棉铃虫时期的寄生率较高；在2，3代棉铃虫时期分别连续释放3次赤眼蜂，对棉铃虫具有很强控制作用，2，3代棉铃虫卵的被寄生率分别为66.0%~70.7%和76.0%~81.2%，均显著高于化防田的自然寄生率（2代：7.0%~12.3%，3代：5.2%~7.4%）；蕾铃被害率分别为2.2%和3.1%，均显著低于化防田（2代：8.5%，3代：20.9%；2代棉铃虫时期，放蜂田和化防田的棉铃虫卵量和幼虫数量差异均不显著，但3代棉铃虫以后，放蜂田棉铃虫卵量和幼虫数量均显著低于化防田，且放蜂田的捕食性天敌数量显著高于化防田。

Different strains have different reaction to the delay of oviducts in body after animal death. After 10min delay C57BL/6 mouse oocytes have death rate of 56.5%,significantely higher than Kunming mouse (47.6%);Spontaneous activation rates were respectively 13.3% and 46.0%, C57BL/6 were obviously lower than Kunming mouse.4. The oviducts were obtained after being delayed 5min 24h after the mice were injected with hCG. The oocytes were cultured in CZB. About 81.1% occurred spontaneous activation, evidently lower than parthenogenetic rate (96.4%) with SrCl_2. Spontaneous activable oocytes had high cleavage rate(93.2%) and 4-cell rate(87.3%). However, spontaneous activable oocytes had blastula development rate(18.7%) as low as parthenogenetic oocytes by SrCl_2(22.9%).

不同品系小鼠卵母细胞对输卵管在体内滞留产生的反应不同，滞留10min C57BL/6系小鼠卵母细胞死亡率为56.5%，显著高于昆明鼠(47.6%)；自发激活率分别为13.3%和46.0%，C57BL/6系小鼠显著低于昆明鼠。4.hCG后24h体内滞留5min卵母细胞在CZB中培养自发激活率为81.1%，显著低于SrCl_2孤雌激活率(96.4%)；自发激活的卵母细胞有较高的卵裂率(93.2%)和4-cell比率(87.3%)，但囊胚率(18.7%)较低，同卵龄的卵母细胞经SrCl_2孤雌激活囊胚发育率为22.9%，差异不显著。
