As results, the contents of three original pimaric-type resin acids, namely pimaric, isopimaric and sandaracopimaric acids, generally decreased, the higher the initial content with the higher the temperature and longer time, the faster the content declined.

结果表明，脂松香中原有的3种海松酸型树脂酸即海松酸、异海松酸、山达海松酸的含量总体呈下降趋势，初始含量越高、热处理温度越高、时间越长，其含量下降幅度越大。

The results show that with Cd2 + Stress Pistia stratiote large increase of the concentration of leaf tissue of the chlorophyll content decreased, while the MDA, soluble protein content, proline content, lipid membrane permeability, SOD, POD, CAT, nitrate reduction The first enzyme content was increased at different times and reached a peak after the downward trend.

结果显示，随着镉胁迫浓度的增加大薸叶组织内的叶绿素含量呈下降的趋势，而丙二醛、可溶性蛋白含量、脯氨酸含量、脂膜相对透性、超氧化物歧化酶、过氧化物酶、过氧化氢酶、硝酸还原酶的含量呈先升高并在不同的浓度达到高峰后再下降的趋势。

孟庆伟等（1996）认为光呼吸可减轻光抑制，尤其在发生光合午休时更明显，而对光合作用却有反作用，Zelitch (1992)的研究表明光呼吸随温度的升高而升高，因此高蛋白小麦中午较强的光呼吸作用可能是其Fv/Fm下降较少，而净光合速率下降幅度较大的一个重要原因。

Pluvialis, at the pH range of 7.5-8.0, the Fv/ Fm, Fv/ F0,ΦPSⅡand ETR increased following the rising of pH, with their maximum values at pH 7.5, Fv/ Fm and Fv/ F0 decreased significantly over pH 7.5, while the decreasing trend didn't change obviously in ΦPSⅡ and ETR.

pluvialis CG-11叶绿素荧光动力学参数呈现出相似的趋势，在6.0－7.5范围内，Fv/ Fm、Fv/ F0、ΦPSⅡ和ETR值随pH升高而增大，pH为7.5时达到最大值，pH超过7.5时，Fv/ Fm和Fv/ F0值明显下降，而ΦPSⅡ和ETR的下降趋势不明显。

The experimental results show that the interaction between polysilicic acid characterized negative charge and hydrolyzed aluminum species results in the decrease in the charge-neutralizing ability of PASC, in comparison with PAC.

研究结果表明，在 PASC 中，由于带负电荷的聚硅酸与铝水解聚合产物间的相互作用，使得 PASC 的电中和能力较 PAC 有所下降，其下降程度与 PASC 的碱化度和 Al/Si 摩尔比密切相关，B 值和 Al/Si 摩尔比越小，则 PASC 的电中和能力就越弱。

Results The ponderal index of brain, thoracic gland and spleen and SOD activity are significantly decreased, while the MDA content increased (P.01) in D-galactose-induced subacute mice. Shouwu soft capsule can improve the ponderal index of brain, thoracic gland and spleen and the SOD activity in blood serum and brain tissue and reduce MDA content.

结果：D-半乳糖诱导的亚急性衰老小鼠脑、胸腺和脾的重量指数明显下降，SOD活性明显下降(P.01)，MDA含量明显提高(P.01)等衰老改变，首乌软胶囊能够提高亚急性衰老小鼠脑、胸腺和脾的重量指数，提高血清和脑组织中SOD(P.01)活性，降低MDA含量(P.01)。

Deep grand of far water shade drop in temperature principle: Water shade and fan install the two sides wall in workshop respectively, when fan convulsions, make the air of workshop forms negative pressure, the not saturated air outside forcing workshop sheds the surface with classics water poriferous and wet shade, cause moisture to evaporate absorb a large number of latent heat, drop the temperature of air oneself thereby, below the action of fan, the humid air of these temperature that be redu

深弘远水帘的降冷元理：水帘微风机分别装在车间的双面墙头，风机抽风时，使车间的空气air产生负压，强使车间外未饱满的空气air流经水帘多孔湿滑的外面，引发水份辉发吸收非常多潜热，进而下降空气air本身的温度，在风机的作用以及影晌下，这一些被下降温度的湿滑空气air就涛涛不停的步入车间。

Here, we took demonstration study of the ecological impacts of disconnection from the river on fish recources in Zhangdu Lake. Our results showed that:(1) Fishery mode changed and the rate of wild fishery production changed from 95% in 1949 to less than 5% in 2002.(2) Fish species have decreased from 80 in 1950s to 52 at present, and the rate of migrant and potamic species decreased from 50% in 1950s to 30% at present.

我们以涨渡湖为例开展江湖阻隔后对单个湖泊鱼类资源所产生的生态影响进行研究，结果表明：江湖阻隔导致湖泊生产经营方式改变，使得野生渔业产量的比例由1949年的95%，降低到2002年的不足5%；江湖阻隔后湖泊鱼类种类由50年代约80种下降到现在的52种，其中，洄游性和流水型鱼类比重由50%下降至不足30

Whereas levels of sedation were similar between groups at each observational time point, decreases in HR and MBP from presurgery baseline during the 1-4 h postoperative period were significantly enhanced in group D patients (by a range of 5-7 bpm and 10-13%, respectively).

虽然在每个观察记录的时间点，两组术后镇静的程度相似，但是D组在术后1至4小时的心跳及血压与其术前相对基准值之差，两者下降的程度皆比M组来得明显下降范围分别为每分钟5-7次与10-13%）。

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）。
