Aim:To study the effect of Dieldrin on dopamine,serotonin(5-HT)and their metabolites. Methods : The C57-BL mice were divided into 3 groups,and were administrated orally Dieldrin 50mg/kg body weight,40mg/kg body weight andequal amount normal saline ,respectively.

目的：探讨急性Dieldrin中毒对C57BL小鼠纹状体多巴胺及其代谢产物含量的影响。

In fact, it's been reported that only 20% of dieters who have lost 10% or more of their body weight are able to keep that weight off for more than a year.

事实上，据报道，只有20 ％的节食者失去了10 ％或更多的体重，还能够保持体重一年多。

Therefore, the effects of ionic strengthof eluents and sample concentration on the molecular weight determination of acidicpolysaccharides and neutral polysaccharides were investigated in HPGPC(Ultrahydroge〓 column) for the first time. Meanwhile, the chromatographiccondition for molecular weight determination of polysaccharides by HPGPC wasoptimized with Dextran series as standards to perform calibration plot.

为此，我们首次采用HPGPC(Ultrahydrogel〓柱)探讨了流动相的离子强度以及样品浓度对中性多糖和酸性多糖分子量测定结果的影响，并对HPGPC测定多糖分子量的条件进行了优化。

Many falconers practically hold a party to ensure that this period of time is fully taken advantage of. The bird is not allowed to sleep for an extended period of time, usually more than 24 hours as the sleep deprivation helps the manning process. The bird's system is also left empty for a day or so allowing her to come down to her flying weight - that weight at which she is most motivated to be hunting.

很多人都是讲鸟带到聚会场所，以确定这段时间得到充分的利用，这些鸟在相当长的时间是不允许睡觉的，通常是连续24小时的睡眠剥夺以帮助鸟&熟悉&，同时，鸟的体重得以控制，以达到出猎体重。

Results The body weight, visceral fat and body weight ration, as well as the levels of blood glucose, insulin, triglyceride, total cholesterol, LDL, and total FFA, were significantly lower in high fat-fed group than in control group (P.01). The aortic tunica intima was intact, the number of foam cells was decreased, and inflammatory cells infiltrated into the med-intima smooth muscle of the n-3 PUFA group. However, with no such changes were observed in control and n-3 PUFAs groups.

结果 n-3脂肪酸组大鼠体重第1~11周均明显降低，空腹血糖、血清胰岛素、TG、TC、LDL-C、总FFA和内脏脂肪占体重百分比均明显低于HF组，HDL-C则明显高于HF组，与对照组无明显差别；n-3脂肪酸组大鼠主动脉主动脉内膜完整无内皮细胞脱落现象，内膜下泡沫细胞及炎细胞浸润减少，内膜的NF-κB呈弱阳性表达，IκBα呈阳性表达，ICAM-1和MCP-1均呈阴性或弱阳性表达。

The results indicate that:(1)Compare with the comparion, the soil physics character are improved after vegetation restortion , the soil unit weight in cyclobalanopsis glauca, Pinus elliottii, Robinia pseudoacacia , mixed forest and fire slash shrub separatly are 1.525g/cm~3, 1.426 g/cm~3, 1.625 g/cm~3, 1.482 g/cm~3, 1.423 g/cm~3. We can find the soil unit weight in other forest all bigger than the comparion (1.580 g/cm~3) except Robinia pseudoacacia .All these mean forest soil is looser and better capacity for aerated and dank.

结果表明：(1)植被恢复后林地土壤物理性质有良好的改进，青冈、湿地松、刺槐、混交林、火烧迹地灌丛容重分别为：1.525g/cm~3、1.426g/cm~3、1.625g/cm~3、1.482g/cm~3、1.423g/cm~3，除刺槐外其他林地均低于对照(1.580g/cm~3)，上述几种林分的孔隙度分别为：45.872%、51.956%、44.093%、50.485%、55.648%、47.228%，说明林地内土壤较对照更为疏松、通气透水能力更强，更有利于土壤微生物的活动，为研究区土壤肥力的提高奠定了基础。

For to analysis the change of variable relation change to arouse the change of investment portfolio weight,We analysis mixed Copula model in fitting relation change and reflecting the change of investment portfolio weight, conclude that mixed Copula has some extent exaction but this method has much risk .

针对变量相关性的变化引起投资组合权重的变化，分析了混合Copula模型在更好地拟合相关性变化以及反映权重变化中具有一定地准确性，但存在巨大地风险。

Wheat physiological char acte rs show two stages by the dividing line of anthesis.In prophase,it mainly forms tillerings,differentiates the floscules and small heads,forms the base of heads number and grains number.In anaphase,it mainly accumulates effectively dry substance ,makes certain the grains number and grains weight ,so we can confirm the t hree yield factors,that is,heads number,grains number and grain weight.

在小麦生理性状的表现上以扬花期为分水岭分2个阶段，前期主要形成分蘖，分化小花、小穗，决定产量构成的亩穗数和穗粒数；后期表现干物质的有效积累，确定粒数、粒重，从而构成产量的三大因素：亩穗数、穗粒数和粒重。

These must be added to check valve weight for full foot valve weight.

对于全部底阀重量，这些都必须加入止回阀中。
