可以抑制的

We selected copper chlorophyll and copper sodium chlorophyllin to have experiments of culturing microalga, under the same of illumination and the concentration of nutrition, comparing with copper ion. The results show that under the condition of illumination, a certain quantity of photosensitizer can produce a great quantity of active oxygen, which has strong effect of death; Copper chlorophyll and copper sodium chlorophyllin have very strong influence to growth of microalga.

由于叶绿素铜钠是水溶的，而叶绿素铜是油溶的，导致微藻对它们吸附性质的不同，微藻吸附的少量叶绿素铜钠促进了微藻的生长，而叶绿素铜在低浓度时对微藻的生长具有促进作用，在高浓度时可以抑制微藻生长、甚至杀灭微藻。

Based on kinematics modeling, two models aiming at irrotational displacement isolator are simulated and analyzed. The result shows that the framework effectively isolates the vibration, restrains angle displacement and plays important role in improving the image quality.

在运动学模型的基础上，对减振机构的两种模型进行仿真、分析其运动特性，结果表明该机构可以有效的隔离振动、抑制角位移，对系统成像质量的提高具有重要的意义。

Simulation results show that the performance of the open-loop control system is poor when the model parameters change. The second system is designed via feedback linearization method. Since the path signal is introduced as feedback signal, the designed closed-loop control system improves the system robustness to the parameter perturbation. Simulation results verify that the closed-loop control system shows better performance than the time optimal control system.

前者侧重于时间最短的控制性能，但由于是开环控制，当出现参数摄动时，系统的性能会受到较大影响；后者由于引入了飞艇轨迹的反馈信号，因而相对提高了系统对参数摄动的鲁棒性，计算量较小，并且仿真结果证实了这种闭环系统设计方案可以抑制参数摄动带来的影响，与时间最优开环控制系统相比，显著提高了控制精度、改善了控制效果。

By analyzing the theory of higher order cummulants and higher order spectrum ,the methods of machine fault feature extraction are researched based on higher order spectral analysis by using the character that higher order spectrum can restrain the gauss noise.

在分析高阶累积量与高阶谱的理论基础上，利用高阶谱可以抑制加性高斯噪声的性质，研究了基于高阶谱分析的机械故障特征提取方法，提出了基于双谱估计的齿轮故障诊断的方法。

A precondition was that the stand diameter grew 2 cm every year. For Evodia meliaefolia community, in the competitive living space by close cover stand, the ratio remained low for ten years with little fluctuation. However, in the unlimited open space, the ratio reached two peak values, with the first appearing in the eighth year, and the second in the eleventh year.

在假设了楝叶吴茱萸和油茶每年胸径生长2 cm的前提下，楝叶吴茱萸冠层总面积变化规律是：在郁闭林分被抑制的生长空间里，楝叶吴茱萸冠层总面积扩散速率可以长达10多年基本维持在一个很低的水平下，而且基本没有太大的变化；在获得充分开阔的生长空间里，楝叶吴茱萸冠层总面积扩散速率出现两个增长高峰，一个出现在第八年，一个出现在第十一年。

Moreover, exogenously added IL-4 inhibited SsAg-induced decrease of Bcl-2, caspase-3 activation, and apoptosis in CD4+ T cells from healthy subjects.

此外，外加介白质-4可以抑制健康人的CD4阳性T细胞之金黄色葡萄球菌超级抗原引起的Bcl-2的减少、caspase-3的活化、及细胞凋亡。

As similar defects are not exhibited by mice that experience systemic inhibition of NF-B, we postulated that the morphogenetic defects in IKK--deficient mice are not caused by reduced NF-B activity but instead are due to failed epidermal differentiation that disrupts proper epidermal–mesodermal interactions.

因为类似的缺陷没有出现在经历了全身NF-B抑制的小鼠，作者推断IKK缺失小鼠的形态发生缺陷不是由于NF-B活性降低引起而是因为可以破裂专属表皮－中胚层相互作用的表皮分化失败引起。

The role of DDAH is to break down modified amino acids Asymmetric dimethylarginine (ADMA and monomethyl arginine that are produced by the body and have been shown to inhibit NO synthase.

DDAH的作用是破坏由体内产生的被修饰的氨基酸（不对称的二甲基精氨酸和一甲基精氨酸）并已证实它可以抑制NO的合成。

Basically, the distribution patterns of most trace metals can be divided into iron style and manganese style, both of which were controlled not only by their different remobilization degrees, but the different input from coal mining drainage, mainly influenced by pH.

Fe型元素与Mn型元素分布差异的原因可以简约的概括为：锰的界面循环极为强烈，导致再迁移程度很高；而铁的循环相对较弱，又容易受到上层硫酸盐还原作用的抑制，因此再迁移程度不高。

The mechanical strength, solubleness and the capability to induce ossification of the materials could be improved obviously when strontium was added, which were formed of hydroxyapatite and tricalcium phosphate.

试验研究证实锶盐具有抗骨吸收和增加骨形成的作用，锶盐可以抑制破骨细胞的活性，促进成骨细胞的活性，促进骨盐的沉积；其与羟基磷灰石和磷酸三钙等复合后，其机械强度、溶解性及诱导成骨能力等特性明显得到改善；锶盐口服有治疗骨质疏松症的作用。

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。
