此外，优化了灵芝的电激转基因方法，选择最佳的电激参数，将hph基因导入灵芝基因组中，转化效率达到约50个转化子／10〓个原生质体。

A dynamic interaction schematic of an end bearing or elastic bearing pile with arbitrary force at pile top is founded. By using Helmholtz resolution and the operator decomposition method, Biots equations governing motions of a porous solid saturated with interstitial fluid are decoupled.

建立饱和土中端承桩和摩擦桩在任意激振力作用下的理论模型，利用位移势函数及微分算子分解方法，得到饱和土层Biot动力固结方程的分离变量解。

This behavior is suggested to be originated from delocalization of the localized carriers by thermal activation.

由变温光激萤光光谱，观察到随温度增加能量峰值有下降、上升再下降的现象，此S型行为是因为载子受到温度的活化，脱离原本的局域态而跃迁到高能量能态。

From the opposite direction of the parameter variation, the chaotic quasi-attractor suddenly changes to a chaotic quasi-transience due to the sudden appearance of a stable elliptic island chain as the leaking hole inside it. This resembles the conventional crises.

从相反的参数变化方向看，混沌类吸引子在此参数临界值由于它内部突然出现一个稳定的椭圆岛链作为逃逸孔洞而突然转变为混沌类瞬态，这类似于传统的激变行为。

In addition, the promoter of SRPP gene contains a variety of stress-responsive elements, such as HSE,MBS, TC-rich repeats, ABRE, EIRE and W box etc. These data suggest that SRPP is not only involved in rubber biosynthesis, but also plays an important role in response to various stresses in rubber trees.

此外，SRPP基因启动子还具有热激响应元件、干旱胁迫响应元件、防卫和胁迫响应元件（TC-rich repeats）、脱落酸响应元件、赤霉素响应元件和激发子响应元件等，这表明橡胶树SRPP基因不仅参与调控橡胶生物合成，而且可能是橡胶树中响应逆境信号的抗性基因，在橡胶树抵御逆境胁迫的生理过程中发挥重要作用。

The step response and impulse response of homogeneous earth half space, marine double half space and four-layer earth models to horizontal electric dipole source were computed in this paper. A concept of transient impulse time was put forward.

本文计算了水平电偶极子源均匀大地半空间，海洋均匀双半空间和海洋四层模型的阶跃响应和冲激响应，提出了瞬变冲激时刻的概念。

The relation of pre pressure, excitation volt for longitudinal vibration,excitation volt for torsional vibration, friction force, torque output, speed of rotor, and vibration speed of torsional vibrator is discussed.

根据模型讲座了预压力Fpre、纵振激振电压Vl、扭振激振电压Vt、摩擦力f、电机的输出扭矩Mout、转子转速ωR和扭振子振动速度ωV等的关系。

Animal's welfare can be feed back from their vocalism. We had some experiments to get 35 days old chicken's vocalization in different environment, including normal environment、 light off environment and people's disturbing environment. On the base of Mel Frequency Cepstral Coefficient, We introduction a new algorithm for feature extraction---Subband Mel Spectrum Centroid. We used support vector machine classification model to evaluate the performance of using different sound parameters.

本文通过研究35日龄海兰褐蛋鸡在正常状态、光照与人为干扰等应激下发声信息的变化特征，提出基于子带梅尔频谱质心的优化特征参数，并通过建立支持向量机模型，比较了采用优化特征参数与梅尔频标倒谱系数及其一阶、二阶导数组成的特征参数（MFCC_39）在识别不同应激中的应用效果。

METHODS AND RESULTS: Using both primary peritoneal macrophages and studies in advanced atheromata in vivo, we introduce signal transducer and activator of transcription-1 (STAT1) as a critical and necessary component of endoplasmic reticulum stress/type A scavenger receptor-induced macrophage apoptosis.

方法和结果：通过使用原代腹膜巨噬细胞研究在体脂质斑块，我们引入信号转导子和转录激活子-1(STAT1)，作为内质网应激/A型清道夫受体诱导的巨噬细胞凋亡中关键和必要组分。

The promoter of mitochondria-localized small heat shock protein gene in Lycopersicon esculentum (Lehsp23.8) is characterized as strongly heat-inducible.

番茄线粒体小分子热激蛋白(Lehsp23.8)启动子是典型的热诱导启动子。

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。
