Results The mortality of senile group was 6.60%, it has signifacantly higher than that of control group and the value of ALT, AST, SB in senile group were significantly higher than those in control group before treatment, the cure rate of ALT,AST in senile group was significantly lower than that in controul group and the cure rate of SB has no significance in two groups.

Results The results showed that the optimal extracting technique of total alkaloids from Flos Datura was that 80 percent sulf-alcohol,and pH of sulf-water was 3,and the extracting time was 3,and the volume of solvent was 4 times as much as the amount of crude drug.

结果 洋金花总生物碱的最佳提取工艺为，使用80％的酸水乙醇，酸水pH值为3，提取3次，使用相当于药材量4倍的溶剂量。

Compared with the control, the vacuum package or adding deoxidant package with materials of low venting quality can constrain the accelerating speed of PV and AV, and delay rancidity.

采用低透气性的包装材料进行真空包装或添加脱氧剂包装，可明显抑制过氧化值和酸价的增加速度，延缓酸败。

Methods: The analytical column was SHIMADZU VP-ODS C18 column(4.6 mm×150 mm 5 μm) with a mobile phase consisted of 0.05 mol/L disodium hydrogen phosphate solution(85% phosphoric acid solution with pH adjustment to 2.5)-acetonitrile-methanol(42.5∶47.5∶10) at the flow rate of 1.0 ml/min the detection wavelength was set at 254 nm.

目的：建立丙酸氯倍他索尿素乳膏中丙酸氯倍他索含量的HPLC测定方法。方法：色谱柱为SHIMADZU VP-ODS C18柱(4.6 mm×150 mm5 μm)流动相为0.05 mol/L磷酸氢二钠溶液(用85%磷酸溶液调节pH值至2.5)-乙腈-甲醇(42.5∶47.5∶10)流速为1.0 ml/min 检测波长为254 nm。

The results of functional magnetic resonance: N-acetyl-aspartic acid, choline and creatine in left temporal lobe and anterior part of frontal lobe decreased more obviously and regional cerebral blood volume and regional cerebral blood flow in these areas decreased,while average pass time and peak time of the contrast medium in these areas slightly increased as compared with those in the conitralateral areas; fraction of anisotropy values and the tracked fasciculus in left corticospinal tract decreased, and the connecting fibers between Broca and Wernicke areas also decreased as compared with those in the contralateral area.

功能磁共振检查结果：左侧颞叶和额叶前部的N-乙酰天门冬氨酸、胆碱、肌酸均较对侧明显降低，左侧颞极及额前部的局部脑血容量、局部脑血流量较对侧降低，对比剂平均通过时间、达峰时间较对侧轻度延长；左侧皮质脊髓束部分各向异性值及追踪到的纤维束较对侧减少，Broca区与Wernicke区之间的联系纤维与对侧相比减少。

This paper put forward three ways: Oxidation-reduction titration, ferruginous spectrophotometry, and direct spectrophotometry. Every way is applied in PH fit for itself. Every way should pay attention to some ways.

本论文确定高铁酸钾的三种定量分析方法：亚砷酸钠氧化还原滴定法、邻二氮杂菲分光光度法、直接分光光度法，并明确了每种方法的适用PH值范围和应遵守的相应注意事项。

Amino acid analysis indicates that the contents of Ser,Thr,and Cys of the alkali treated rice protein decrease obviously under pH 13.5 at a glutelin concentration of 9%.

氨基酸分析表明，9%的谷蛋白含量、pH值为13.5碱处理大米谷蛋白的丝氨酸、苏氨酸、胱氨酸含量明显下降。

PH-20 is a traditional sperm membrane antigen,and it is a glycophosphatidylinositolanchored hyaluronidase.

PH-20(posterior head 20)作为传统的精子膜抗原，是由磷脂酰肌醇(glycophosphatidylinositol，GPI)锚定的膜结合型透明质酸酶，最适PH值呈中性，它分布于精子表面浆膜和顶体内膜，是一种透明质酸酶诱导信号转导的受体和识别透明带的受体。

Utilization ofantiseptic would not be affected by temperature or pH.The antiseptics had a longperiod of validity,the effect is much better than most other antiseptics,could notarose skin hypersusceptibility,resist to metabolization,and had a wide utilizationrange.

研究中采用了本实验室自行合成的抗菌剂反丁烯二酸桂醇甲酯，测定了反丁烯二酸桂醇甲酯在不同的pH值、不同温度、不同浓度条件下的抑菌活性、抑菌谱，并与其它常用抗菌剂的抑菌效果做了比较。

The results show that the inhibition effect of phytic acid is obvious,and it is an ideal improver for quality of germinant wheat.

通过测定不同植酸添加量下的α-淀粉酶活性及降落值，表明植酸对α-淀粉酶的抑制效果十分明显，是一种理想的芽麦品质改良剂。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
