It is antinomy to analysis factor effects according to first and second order term index of quadratic polynomial,so this paper put forward a new method to explain and evaluate factor effect by F test based on partial regression sum of squares.

传统的二次多项式回归方程在依系数正负、大小解释各因子效应时，常出现一次项与二次项结果相互矛盾的情形，而一般的SVR模型又不具解释性；本文从偏回归分析定义出发，建立了基于SVR以F测验解释、评价各因子相对重要性的方法。

When you control your reaction to the seemingly uncontrollable problem of life, then in fact you do control the problem's effect on you.

当你控制在生活中表面看来不可控制的问题的反应时，实际上是在控制该问题对你的影响。

The potentiodynamic polarization results showed that anodic reaction of carbon electrode was activated with uranyl ion in given potential sweep.

电化学阻抗谱研究结果显示，铀酰离子与铁表面有复杂的电极动力学过程，在铁与铀酰离子反应时，在铁表面存在活性的反应位，形成氧化铀和氧化铁的中间化合物。

The presence of solvent disfavors the reaction, whereas the participation of water in the aminolysis reaction plays a positive role and reduces the activation energy greatly.

没有水分子参与的情况下，路径a的反应能垒最低，而在有水分子参与反应时，按协同机理反应生成P2的反应路径略占优势。

Compared to the nearest 16 × 16 crosspoint switch alternative, the ADV3226 and ADV3227 deliver an unmatched combination of 50 percent less power at 1.2 W from a ±5 V supply and a 55 percent increase in speed at 700 MHz the industry's highest bandwidth.

相较于最新的16×16交叉点交换器同构型产品，ADV 3226与 ADV 3227在使用± 5V 电源供应时，于1.2W 下能够减少50%的功率消耗，以及在业界最高的频宽─700 MHz 下，速度能够提升55%。

The hydrodynamic pressures have to be taken into account in the seismic responseanalysis of dams subjected to earthquake excitation.

在研究大坝的地震响应时，水的作用是不可忽视的一种外荷载。

To solve the problem of channel with distortions, an adaptive circuit is configured by a new laddered method based on relevant articles, and simulation study was made on four dimensional Chua's chaos oscillator. The simulation results demonstrated that: synchronization of two chaotic oscillators can be achieved when adaptive circuit has adaptive capability. Synchronization of two chaotic oscillators cannot be achieved when adaptive circuit has no adaptive capability. Simulation studies were done for five scroll chaotic oscillators that achieve bond-orbit, coupling and pulse synchronization.

为了解决信道畸变问题，根据相关文献提出的梯度法，本文构造了一种自适应同步电路，并以四阶变型蔡氏混沌振荡电路为例进行仿真研究，仿真结果表明：当自适应同步电路具有自适应效应时能实现有噪声干扰情况下的两个混沌振荡电路的同步；若自适应同步电路没有自适应效应时，则不能使两个混沌振荡电路同步；以5涡卷混沌振荡电路为例用键波同步法、耦合同步法、脉冲同步法进行同步仿真研究。

This result suggest thatthis may be one of the mechnism that let tumor cells keep its activityand escape from death when they were in condition of laking bloodsupply.

这说明人肝癌细胞在缺乏正常的血清供应时，其EGFR的表达也明显增高，提示这可能是肿瘤细胞一个保持活性和&逃避死亡&的机制。

When a patient with pneumonia has a history of soil or river water aspiration and the lung infection responds poorly to antimicrobial therapy for community-acquired pneumonia, pulmonary nocardiosis should be considered and a careful search performed for evidence of the organism is necessary.

从这个病例，我们可以学到当病患有接触泥土或受到污染的水的病史时，而且病患对於治疗社区型肺炎的抗生素毫无反应时，必须将土壤菌丝属肺炎列入鉴别诊断。

Promoted by metal dysprosium, aldehydes and ketones could react smoothly with propargyl bromide to afford the corresponding homopropargylic alcohols in good to excellent yields, and no allenic alcohol s were found.

当用苯基炔丙基溴代替炔丙基溴与醛、酮反应时，主要得到了相应的连二烯醇，而没有发现高快丙醇的存在，由此提出了六元环过渡态的反应机理
