The later chicory root harvested, the time of vernalization was shorter and the carbohydrate in it was higher.

菊苣根采收的越晚，需要春化的时间越短，菊苣根中碳水化合物的含量也越高，菊苣根采收以后短期时间内，还原糖的含量呈现急剧上升的趋势，非还原糖缓慢下降，并且采收的越晚，还原糖上升的幅度越小，非还原糖下降的幅度也越小。

Most species' populations were decline in last fifty years, especially since the last 1980's, the populations such as Alpine Musk Deer, Przewalski's Gazelle and Red Deer etc. declined dramatically;(5) Desertification and grassland degredation are obviously affected by climate change on macrographic scale, anthropogenic activities is an important driving role for desertification, herbing, land-development and urbanization have majority impact to biodiversity spatial pattern and its loss.

祁连山区动物资源组成成分复杂，总体上缺乏自身特有的种类，哺乳动物区系特点不很突出，既包含了东部黄土高原和东南湿润地区的兽类成分，又不乏青藏高原特有种类，同时还与新疆的动物区系有一定的联系，近50年来尤其自上个世纪80年代以来，多数种类的种群数量呈下降趋势，其中以马麝、普氏原羚、马鹿等物种的数量下降的最为显著；（5）土地沙漠化和草地退化在宏观尺度上受气候因素影响较大，人类活动对荒漠化的加速发展起着重要的驱动作用，尤其是放牧、土地开发和城镇化建设对生物多样性资源减少以及空间分布格局影响较大。

In conclusion, these results suggested that (1) the ageing-associated decline in fertility of female KM mouse was due to a decrease in both quantity and quality of oocytes;(2) the ooplasm from young mice did not correct the meiotic errors of aged mice, and the ooplasm from aged mice did not induce abnormal segregation of meiotic chromosome of young mice, indicating that meiotic anomalies found in the oocytes of aged mice might be related to nucleus or chromosomes and relevant factors;(3) a critical nucleocytoplasmic ratio was essential for normal maturation and segregation of meiotic chromosomes of oocytes and development to 2-cell embryos.

本研究结果表明：（1）昆明白小鼠与衰老相关的生育力下降是其卵母细胞数量减少和质量下降的综合结果；（2）年轻小鼠卵母细胞细胞质不能纠正老龄小鼠GV的减数分裂错误，老龄小鼠卵母细胞细胞质也不诱导年轻小鼠的GV发生减数分裂错误，老龄小鼠卵母细胞减数分裂异常很可能与细胞核或染色体及其相关因素有关；（3）关键的核质比对卵母细胞正常的成熟、减数分裂染色体分离及2-细胞期胚的发育是绝对必需的。

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。

The main fatty acid from longissimus, kidney and tailhead fat obtained from each carcass were measured by gas chromatography technology.

日粮中分别添加相当于40.0g粗脂肪的油菜籽、油葵籽、红花籽和亚麻籽，饲喂成年母羊35d后屠宰，用气相色谱技术测定了羊体背最长肌、肾脏脂肪和尾部脂肪的主要脂肪酸组成，结果表明：日粮对肌肉中FA组成的影响较对脂肪组织的大；在所测定的3个部位中，C14：0最为稳定，不受日粮影响；在脂肪组织中，C16：1、C18：1也不受日粮的影响，但肌肉中C18：1含量因添加红花籽显著增大；添加亚麻籽有提高脂肪组织中C18：3的趋势，其余油籽有使各部位C18：3含量下降的趋势，以油葵组下降最为明显；除油菜籽（富含C18：1）外，富含多不饱和脂肪酸的油籽有使C16：0降低的作用。

Results In contrast with enzymatic dissociation, the method of mechanical dissociation, breaking up great neurospheres into small spheres with gradually reduced pipette, had advantages of raising cell viability and shortening cell doubling time (P.05). After NSCs being cultured long term in vitro, the number of neurons generated decreased with passaging, whereas the number of astrocytes increased.

体外长期培养条件下，随着培养时间的延长，NSCs分化为神经元的比例逐渐降低，星形胶质细胞的比例逐渐增高；在4~12代NSCs分化为神经元的能力表现出下降的趋势，但仍较为稳定；12代后，神经元的分化比例迅速下降，星形胶质细胞的比例迅速上升。

Long-term aerobic exercise can effectively prevent hepatocyte number from decreasing accompanying with aging. Among the groups of aged, results showed that rats of 1-hour and 2hours group whose recovery function of hepatocyte apoptosis were of most significant. The increasing number of hepatocyte might be one of the cytological mechanisms of how aerobic exercise delays cell aging. Further researches on the phenomenon of the anomalous change of the hepatocyte apoptosis ratio among the youth groups are needed expectably.

肝细胞凋亡存在随增龄明显下降的趋势，这对维持肝细胞数量或缓解增龄过程中肝细胞数目丢失具有十分重要的意义；长期有氧运动可以有效的阻止肝细胞凋亡率在增龄过程中下降的趋势；在老年前期组中，训练1小时和2小时组对肝细胞凋亡能力的恢复作用最明显；有氧运动促进肝细胞凋亡能力的提高可能就是有氧运动延缓细胞增龄发生和发展的重要细胞学机制之一。

The results indicated that in the WSSV infection process of the organism, the haemocyte density rose at first and then declined, the value was only 1/5 of that at normal; the percent of infected haemocyte rose and declined at the end as well, but the virus amount in the infected haemocytes kept rising; the organism was going to die when the infected ratio of haemocytes rose to the highest value, revealed that the WSSV infection degree of haemocyte has a close relationship to that of the organism.

以上结果表明，在机体感染进程中，螯虾血细胞密度呈现先升高后下降的趋势，至后期仅为感染前的1/5；血细胞被感染率同时也呈现了先上升后下降的变化趋势，但被感染血细胞中的病毒量则始终呈上升趋势；血细胞处于最高感染率时机体濒临死亡，表明血细胞的WSSV感染程度与机体的感染状况密切相关。

Tuck a hot-water bottle between your feet or wear a pair of ski socks to bed.

在两脚间塞一个装热水的瓶子，或者穿双滑雪短袜其中的科学原理有些复杂，不过暖脚能帮助身体内部体温达到适合睡眠的最佳温度基本上，当你身体中心温度下降的时候你睡得最香通过脚的加温，腿部血液流动加快，躯体的温度就会下降

Tertullian's list of customs observed by Apostolic tradition though not in Scripture (De cor., iii) is famous: the baptismal renunciations and feeding with milk and honey, fasting Communion, offerings for the dead on their anniversaries, no fasting or kneeling on the Lord's Day and between Easter and Pentecost, anxiety as to the falling to the ground of any crumb or drop of the Holy Eucharist, the Sign of the Cross made continually during the day.

德尔图良的名单海关遵守使徒传统虽然没有在圣经是著名的：放弃的洗礼和餵养的牛奶和蜂蜜，空腹圣餐，产品为死者对他们的纪念日，没有空腹或跪对基督日和复活节，圣灵降临节之间，焦虑至於下降到地面的任何屑或下降的圣体圣事，该申请提出的跨不断在白天进行。
