The results show that total N, Cl-, organic matter, humic acid content of soil improves under vinasse treatments. Catalase and polyphenol oxidase activity increase abnormally at sugarcane settling stage and then sharply decrease to CK2 level at sugarcane maturity stage.

结果表明：蔗地施用废液提高了土壤全氮、Cl-、有机质、腐殖质含量，使甘蔗苗期土壤过氧化氢酶和多酚氧化酶活性异常升高，随后迅速下降，成熟期下降到接近或小于CK2的土壤酶活性水平。

The increase of the recycled proportion, stability value rises but fluidity value drops, viscid degree reduces with decline of the recycled proportion, the size of oil content does not change with RAC recycled proportion .

再生比例的增加，稳定值上升而流度值下降，黏滞度随再生比例之下降而减少，含油量大小并不随RAC再生比例而有所变化。

Results Compared with the NS control group, TRH administration could raise the MAP instantly and remained it at higher level. The water contents of burn wound and viscus were significantly lower in TRH group than in NS control group, while the activities of SOD in plasma and viscus were higher and the contents of MDA lower.

结果与NS对照组相比，TRH治疗后，大鼠的血压上升并维持在高水平，烧伤创面和内脏器官含水量明显下降，同时器官组织SOD活力上升，MDA含量下降。

Low temperature significantly prolonged fruit storage life,delayed the total sugar,total acid and V_C content loss.Between 2 ℃ and 12 ℃,the lower the storage temperature,the better preservation effect.The best storage temperature of wampee was 2-4 ℃. MAP storage could delay the!quality loss of wampee.0.025 mm polyethylene film with the packing capacity of 5.4 kg·m~(-2) were recommended.

结果表明，常温下黄皮果实贮藏期短，常温贮藏3 d后，好果率低于75%；低温能明显延长果实的贮藏期，延缓果实的糖、酸和VC含量的下降；在2-12 ℃间，贮藏温度越低，保鲜效果越好，适宜的贮藏温度为2-4 ℃；采用MAP保鲜技术能延缓果实品质的下降，在2-4 ℃下大鸡心黄皮MAP保鲜的适宜条件是采用0.025 mm的PE膜包装，装果量为5.4 kg·m-2。

Over the last 25 years the amount of energy used by the typical refrigerator dropped by two-thirds;washing-machine energy needs he been reduced by nearly half;the use of redwood decking has fallen by two-thirds;and toilets use less than half the water that they did in the 1970s.

在过去25年中，用于典型的冰箱的能量下降三分之二，洗衣机的能源需求已经减少了将近一半，红木的甲板使用能源的使用量下降了三分之二；和厕所使用不到一半的水，与20世纪70年代相比。

The rapid acetylator would increase the heterocyclic amines from pre-carcinogen to active formation.

随着MTHFR 667 C-＞T的多态基因在基因组中比例升高，其腺瘤复发有下降的趋势，而且饮酒与红烧鱼因素的相对危险度也呈下降趋势。

But on account of excessive cut since 1949, forest resources cutdown sharply, bring a series of problem, for instance, forest productivity decrease, forest habitat fragmentation, agrestic species become extinct at a high speed, environmental quality decline, this paper discussed forest resources change in Heilongjing Province from statistical change feature of forest resources and forest landscape pattern change, using model of GM(1,1) to predict the development trend of forest resources here.

但由于半个多世纪的过量采伐，致使森林资源锐减，带来了森林生产力下降、森林生境破碎化、乡土物种加速灭绝和环境质量下降等一系列问题。本文从森林资源统计变化特征、森林景观格局变化两个方面对黑龙江省森林资源的变化进行了研究，并用灰色理论的GM(1，1)模型对该省森林资源未来的发展进行了预测。

Thirdly, we also examine the effect of these extracts on maize seed germination rate, maize seeding height and fresh weight, and the results show that three extracts are safe to maize at the concentration of 1:20, with a inhibit rate under 4 %.We further identified and purified organic acids, alkaloids hydroxybenzenes and neutral materials from extract and examined their effects on Amaranthus retroflexus L. seeds.

实验结果表明在干样：水为1：50以内，这三种向日葵的叶片提取液对反枝苋种子萌发和幼苗株高、鲜重及出叶数的抑制效果都非常显著；随着提取液浓度的下降抑制作用也呈明显的下降趋势；通过实验数据比较，这三种向日葵叶片提取液对反枝苋种子萌发抑制和对反枝苋幼苗株高、鲜重及出叶数的抑制效果略有差异。

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。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
