不变性

PEEK is a kind of thermoplastic resins which has a lot of excellent properties in many fields and can be reinforced by many types of fillers. When it is reinforced by carbon fibers, its strength and wear resistance are improved. Though PEEK/Cf composite has many advantages, its applications are limited just for it is nonconductive.

PEEK是一种结晶性、不透明、浅茶灰色的芳香族系超耐热热塑性树脂，具有坚韧、高刚性和耐蠕变性好等特点，采用碳纤维复合增强，形成了性能更优越的PEEK/Cf复合材料，提高了PEEK的强度和耐磨性，改善加工性。

The statistical test based on the Shanghai Composite Index suggested that certain technical trading rules should be able to gain stable excess profit in the long run, which could not be explained by nonsynchronous trading, transaction cost and time variation of expected returns. Thus, it can be concluded that the China's Stock Market is not weakly efficient.

对上证指数的统计检验说明一些技术分析规则可以带来长期、稳定的超额利润，而有效市场假定下的异步交易、交易成本和期望时变性都不能完全解释这种超额利润的存在，因此可以得出中国证券股票市场还没有达到弱态有效性的结论。

Based on these observations, we propose that the periplasmic proteins have been evolved to resist the formation of aggregates when subjected to various denaturing conditions and molecular chaperones may thus not be needed in periplasm.

根据这些发现，我们提出假说：膜间质蛋白在恶劣环境条件的选择压力下进化出对各种变性条件所诱导聚集的抗性，而不需要分子伴侣蛋白的有效保护。

Results The neurological defects score was singificiant lower in D group (41.50±8.18) than that in group A(82.20±8.08), B(63.60±6.22) and C (61.00±6.58)(all P.01). Compared with groups A, C, group D showed that the cellular nucleus was shrinkaged slightly, the gap of cells was nomal roughly and the degree of rarefaction in neurofibra net was not serious under the light microscope. Under the electron microscope, the neuron was degenerated, the cellular membrane was integrated and the plastosome was swelled lightly in the group D. The physiological demage were slighter in D group.

结果 D组神经功能缺损评分(41.50±8.18)明显低于A组(82.20±8.08)、B组(63.60±6.22)和C组(61.00±6.58)（均P.01）；光镜下D组神经细胞核轻度皱缩，细胞周围间隙大致正常，神经纤维网疏程度不严重；电镜下D组神经元轻度变性，细胞核无皱缩，核膜完整，线粒体轻度肿胀；脑组织病理损害程度较B组和C组明显减轻。

Thermally denatured DNA was preconcentrated at pretreated GCE by its adsorption in open circuit for 5min or at the potential of+0.3V for 90s, and produced two well-defined oxidation peaks of guanine and adenine residues at+0.80V and+1. 11V in pH 5. 0 phospoate buffer, respectively, but the native DNA did not produce any peaks at the same conditions.

在pH 5.0的磷酸盐缓冲液中，于+0.3V富集90秒或在开路条件下吸附富集5分钟，热变性DNA可以吸附富集在预处理玻碳电极表面，阳极扫描时，鸟嘌呤和腺嘌呤残基产生两个很好的氧化峰，峰电位分别为+0.80V和+1.11V，而在同样条件下，天然DNA却几乎不出现峰。

At 24h, the ischemic area in the preoptic area, striatum and cortex developed into infarct form.

结果再灌注12小时组开始出现神经元不可逆变性，24小时梗死形成。

The model of brain concussion of rat can be established successfully using iron pendulum hitting device; 2. The spatial learning and memory deficits of the rats are detected by MWM in early period post-BC(from 1 to 3 days after BC); 3. Pycnosis degeneration or necrosis neurons of the cerebral cortex, dorsal hippocampus, dentate fornix and brainstem reticular formation are identified in BC rats; 4. There are significantly changes in the number and activity of cholinergic neurons in the basal forebrain and brainstem reticular formation after BC; 5. The change of cerebral neurons and cholinergic neurons correlate with cognitive deficits in BC rats .

1、单摆式闭合性机械打击装置能成功建立脑震荡大鼠模型；2、脑震荡大鼠在MWM实验中出现早期空间认知行为障碍；3、脑震荡大鼠大脑皮质、背侧海马、齿状回和脑干网状结构出现程度不等的部分神经元固缩变性和不完全性坏死；4、脑震荡大鼠基底前脑、脑干网状结构ChAT活性表达有明显变化；5、脑震荡大鼠认知障碍与相关脑区神经元、胆碱能神经元的变化有关联。

The enzyme reductively unfolded is almost unable to renature indicating the roles of disulfide bonds on maintaining the correct tertiary structure of the enzyme.

还原条件下变性的酶几乎不能复性，表明二硫键对于维持酶的特定空间结构是极为重要的。

Results:According to their size, 68 cases of intramural and subserous hysteromyomas were exposed to HIFU, which had focusing property.After treatment, the total efficacy was 100%(68 cases), while cure rate and significant efficacy were 34%(23 cases) and 53%(36 cases) respectively.

利用 HIFU在人体内部的可聚焦特性，用瞬间高温致肌瘤细胞发生不可逆的变性和凝固性坏死，坏死的肌瘤细胞逐渐被周围组织吞噬、吸收，达到其&纯无创&治疗子宫肌瘤的目的。

Note 1: if the pointer will not stabilize, the paint may be thixotropic.

注：如指示器不稳定，涂料可能是触变性的。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
