The parent training program was designed based on the results of interview and testing. 45 adolescents' parents took part in the family intervention program.

根据访谈和测查结果设计了针对父母的干预课程，有45名青少年的父母参加了父母培训的家庭干预项目，干预的结果显示干预组的青少年抑郁分数有显著的下降，羞耻的分数显著下降，但是自尊的分数没有改变。

Results: A decreased body weight was observed. Sucrose preference test showed that percentage of sucrose solution from the total liquid was decreased, which simulates anhedonia (i.e. a loss of responsiveness to pleasant events), a core symptom of depression and the defining feature of melancholia.

结果显示，模型动物体重明显降低；糖水偏好试验显示糖水摄入比例显著下降，这模拟了抑郁症的核心症状——快感丧失；旷场试验中大鼠水平移动格数、直立次数、理毛数明显减少，这分别体现了运动能力及社会交往能力下降、探索行为能力降低等。

Plasma membrane infolding occurred after pretreatment and low temperature stress, one new structure looked like vacuole was recognized between plasma membrane and cytoderm, the emergence of that phenomena maybe concern with plasma membrane infolding and vacuole.

在胁迫过程对照植株光合速率的下降是由非气孔因素引起；锻炼植株光合速率的下降在胁迫的前两天是由气孔因素引起，在胁迫的第三和第四天是由非气孔因素引起。这也从另一个角度证明了低温锻炼提高了植物的抗寒性。

The liquefiable site was simplified as a double-degree-freedom model and the formula for calculating the reduction of horizontal natural frequency induced by liquefaction was attained.

将可液化场地简化为双质点模型，给出了液化导致场地水平自振频率下降的计算公式，推导出了频率下降率的下限值。

Then the author analyzes empirically China's terms of trade from 1981,and the causes of the change in the net barter terms of trade by means of regression analysis ,which can be quantitied.we get the results that China's net barter terms of trade had a declining trend while its income terms and factorial terms of trade had been improved,and the net barter terms of trade positively correlates with actual tariff rate,exchange rate and negatively correlates with GDP,besides,the factors which can not be quantitied such as pure price fighting,inappropiate tariff sytem,foreign-invested enterprises's tranfer pricing and region trade agreement also lead to the above trend of China's net barter terms of trade,and the change in China's net barter terms of trade had a neglect impact on international trade benefit.

得出中国价格贸易条件总体上存在下降趋势，收入、要素条件呈现改善的趋势；实际关税率、汇率与价格贸易条件存在正相关关系，GDP指数与其负相关。出口企业恶性价格竞争、不合理的关税体制、外资企业的转移定价、区域贸易集团是造成中国价格贸易条件下降的非量化因素。此外，本文分析了1981-2004年价格贸易条件变动导致的中国国际贸易利益变化，发现价格贸易条件变动对中国国际贸易利益产生了一定的负面影响。最后，本文在分析中国价格贸易条件变动环境的基础上，认为中国工业化阶段不高、贸易限制性政策实施空间的减小、&合成谬误&现象及知识经济时代的到来会在一定时期内对价格贸易条件变动不利。

Under the base of it, also considering the characteristics of the multi-channel multistage rimfire gas switch, much study and experiments of the surface flashover along the PMMA insulator and the PMMA housing of the switch were done. Following conclusions were drawn: After introducing PMMA insulator among the board electrodes, the voltage of the discharging of the SF6 drops by 30%. With increasing of the pressure of SF6, voltage of the discharging descends more sharply. With PMMA spacer, the dispersing of the discharging voltage of the gas gap increased as compares to the unbridged gap, such increases in value of the discharging voltage become more obvious with the gas pressure increased.

本文对SF6气体中的沿面放电及影响因素进行了分析，在此基础之上结合边缘点火多级多通道气体开关的沿面绝缘结构特点，经过大量理论分析和电场计算，对有机玻璃支撑绝缘和有机玻璃外筒进行了沿面放电研究，研究结果表明：板电极间SF6气体间隙引入有机玻璃绝缘子后，间隙放电电压平均下降约30%，随气压增大放电电压下降趋势增大，引入有机玻璃绝缘子后放电分散性明显增大，随气压增大，放电分散性呈增大趋势。

Due to begin to present differentiation,IEC-6 cells grew slowly.2.This study design and compose three pairs siRNAs to RPS20 of rats,and they interference the expression of RPS20 on the aspect of mRNA and protein successfully,and prove their validity.3.After interference,IEC-6 cells cytoplasm present vacuolization,and its migration,and proliferation were suppressed,but there was no apoptosis to happen.

本课题设计并合成了3对针对大鼠RPS20的siRNAs，而且都能够有效地抑制IEC-6细胞RPS20mRNA与蛋白的表达，表明了序列的有效性；3 IEC-6细胞胞浆空泡化，并且迁移、增殖能力受到抑制，但并没有导致细胞早期凋亡的发生，该结果提示干扰RPS20可能影响IEC-6细胞的消化吸收功能和胃肠粘膜损伤修复功能，与前期收集的脾气虚证患者消化吸收功能下降、黏膜损伤修复能力下降等表现相符合。

However,the number of events and frequency of copulation between the biotype B and ZHJ2 decreased significantly compared with those between females and males of a given biotype being placed in one arena, demonstrating a degree of pre-mating partial reproductive isolation between these two biotypes.Although some of the adults of the biotype B and ZHJ2 copulated with each other,mated females produced only male progeny,demonstrating a post-mating complete isolation in reproduction between the two biotypes in cases where copulation has happened.

4B型烟粉虱与ZHJ2型烟粉虱在棉花上的竞争取代过程当B型烟粉虱与ZHJ2型烟粉虱以3：20的比例在棉花上开始竞争，在未喷施吡虫啉乳油的情况下，B型经过6代完全取代了ZHJ2型，并伴随着B型雌虫比例的上升和ZHJ2型雌虫比例的下降；在喷施吡虫啉乳油的情况下，B型取代速度加快，经过5代完全取代了ZHJ2型，也伴随着B型雌虫比例的上升和ZHJ2型雌虫比例的下降；B型单一种群中，雌虫比例稳定在55%～60%；ZHJ2型单一种群中，雌虫比例稳定在50%左右。

Finally, the death rate in most developed countries declines steadily because people's standards of living are raised and health care improves.

的下降。最后，许多发达国家中的死亡率稳步下降，因为人们生活水平提高了，卫生保健改善了。
