The study of spatial configuration and characteristics of pulsed-wire velocity probe shows that: the yaw-and pitch-response characteristics have a good behavior due to the asymmetrical arrangement of the prongs. Because the amplitude of sensor wire response signal changes with the flow velocity, the differentiated signal is selected to trigger a voltage comparator. The pulsing frequency is restricted to about 100Hz to allow the wire to cool between pulses. The first velocity probe with big acceptance cone has been developed in China, and the way of measuring the Reynolds normal and shear stress and application have been given in this dissertation.

对脉冲热线空间速度探针的空间结构及特性的分析表明：三根长支架平行且安置于同一平面的探针结构可以获得大的测量角和好的测量性能；由于传感丝的响应信号幅值随流速变化较大，故应采用微分法进行信号处理；对于5μm的传感丝由于散热时间基本不变，约为10ms，故脉冲发射的最高频率为100Hz；本文在国内首次研制成功了一种大测量窗的脉冲热线空间速度探针，并给出了测量雷诺应力的方法和实例。

Therefore, how to improve the customized producing throughdistinctive rapid response design while reduce cost and response time has become akey emphasis.

如何利用快速响应设计来解决个性化产品定制问题，降低产品成本，提高企业响应速度成为众多学者关注的问题。

The aim of this study was to reveal the adaptation response of limestone plants to light and water. The light response curves of limestone plants Alchornea trewioides, Bauhinia championii, Pteroceltis tatarinowii, Sapium rotundi folium were measured with Licor-6400 Photosynthesis Analyzer in Karst area, and parameters of photosynthesis were simulated by non-rectangle hyperbolae function.

为阐明石山植物对光与水分的适应能力，采用Li-6400光合作用测定系统，对岩溶区石山植物红背山麻杆、九龙藤、青檀和圆叶乌柏生长盛期的光响应曲线进行了测定，并利用非直角双曲线模型对4种植物光合作用生理参数进行拟合。

Results Anergic T cells express high level of CTLA-4 on the cell surface in the late stages of an immune response, but the level of CD28 expression is a little higher than that of activated T cells during whole immune response.

结果与活化T细胞相比，无能T细胞在免疫应答的后期阶段表面表达高水平的CTLA-4分子，而CD28的表达则只较活化组T细胞稍高一些。

In this study, we therefore hypothesized that changes in intrapelvic neurokinin system and DOR detrimental to renal sensory response in nephropathies and HPC may affect above molecules to prevent the loss of ARNA response.

因此，我们假设快肽、神经激肽受体以及DOR可能在肾脏疾病所引发的肾感觉功能失调中扮演相当重要的角色；并且低氧预处理可能透过这些因子来达到其感觉功能的保护效果。

The fEPSP response evoked in one pathway was small, usually 20–30% of the maximu, whereas a large response, usually 80–90% of the maximum, was evoked in the strong pathway. After recording of the baseline fEPSP evoked at 0.033 Hz, LTP of the weak pathway could be associatively induced by paired stimulation of the weak and strong pathways 100 times at 6 sec intervals, with stimulation of the weak pathway preceded 3–10 msec.

在记录以0.033Hz所引发基础的兴奋性突触后电位之后，在弱的路径上可以因配合弱与强的刺激路径而引发出相关性长期增益（每六秒一次共100次，弱的刺激路径在强的刺激路径之前 3-10 ms），然而当在两个路径之间的配合时间差大於10 ms时即无法形成相关性长期增益，此类型长期增益的引发是需要依赖活化NMDA接受器的，因为给予50 mM的D，L-AP5可以阻断相关性长期增益的引发（兴奋性突触后电位为原来的105±6﹪；n=6）。

The response patterns were analyzed and categorized. The prolonged asystole was searched. Follow up was made at the outpatient clinic or by phone during October 2004. Two hundred forty-two patients (40.1%) had positive response. 172 patients (71.1%) with the mixed type, 60 patients (24.8%) with the vasodepressive type and only 10 patients (4.1%) with the cardioinhibitory type.

反应的型态皆加以分析及归类并寻找有长的心跳停止者而於2004年十月於门诊或电话做追踪。242位病人(40.1%)为阳性反应，其中172位(71.1%)为混合型，60位(24.8%)为血压下降型，而仅有10位(4.1%)为心跳抑制型。
