The results showed: 1 Alfalfas grown for different lengths of time had considerable influence on photosynthetic characteristics of which the most important was stomatal conductance followed by transpiration rate and the chlorophyll relative content. 2 Diurnal variation in Pn and Tr had two peaks, and an obvious midday depression. 3 The net photosynthetic rate was significantly positively correlated with photosynthetic radiation, stomatal conductance, the relative chlorophyll content, and transpiration rate. The net photosynthetic rate was significantly negatively correlated with intercellular CO2 concentration.

结果表明，1生长年限对苜蓿光合特性有较大的影响，对气孔导度的影响最大，其次是蒸腾速率和叶绿素相对含量。2苜蓿叶片净光合速率、蒸腾速率日变化均呈现&双峰&曲线，有明显的光合&午休&现象。3净光合速率与光合有效辐射、气孔导度、叶绿素相对含量呈极显著正相关，与蒸腾速率呈显著正相关，与田间CO2浓度呈极显著负相关。

Then, we construct a coordinate system for terminal bouton of PN in calyx of mushroom body.

Multivariate analysis considering caveolin-1 immunoreactivity in addition to the established prognostic parameters such as pT stage, pN in these patients confirmed that caveolin-1 is an independent functional predictor of poor survival. We further revealed that up-regulated caveolin-1 in CL cells is necessary for mediating filopodia formation which may enhance the invasive ability of lung adenocarcinoma cells.

利用多变数分析的方法分析Caveolin-1及其他已知会影响预后的变数，例如肿瘤大小及淋巴结转移状况等，证实Caveolin-1的确是影响预后的独立变数，最后我们发现Caveolin-1会引起肺腺癌细胞产生伪足，这可能是Caveolin-1造成癌细胞侵袭性增加的原因。

An RMS configuration is formally defined by incorporating the formalisms of set and graph. A design method for a class of modular and reconfigurable PN controllers is presented with an approach of INRS.

以集合和图的组合形式定义了RMS的构形，并提出了基于INRS的一类模块化、可重构的Petri网控制器的设计方法。

ABSTRACT The spread spectrum communication with an aperiodic PN code and under strong man-made jammers has an important significance in military communications.

强人为干扰环境下的非周期扩频码的扩频通信在军事上具有重要的意义。自适应天线是抗干扰的前沿研究课题。

To compare the performance with PN, the trajectory simulation is carried out, and the results show that the new guidance law provides significant performance improvements over the commonly used classical proportional navigation law, the load distribution among the trajectory is reasonable and favorable for the hand-over between the mid-course phase and the terminal phase.

在以上内容的基础上，建立了拦截弹末制导有关的六自由度数学模型和仿真模型，对不同初始条件下拦截飞机和战术弹道导弹进行了数字仿真，分析了拦截高速弹头时弹道的新特点，并采用蒙特卡洛法分析了不同误差因素作用下的制导精度。

Purple-blue sensitivity of Si color sensor with double PN junction is gained through appropraite selection from different structures of devices and technology conditions, on the base of which a device for panchromatic wave band has been fabricated.

通过选择不同的器件结构和工艺条件，得到了色敏器件对蓝紫光的响应，完成了全色波段硅双结型色敏器件的研制。

With a view to knowing more about how NaHSO〓 increased Pn in higher plants, we studied the effects of NaHSO〓 on the cyclic electron flow around PSI in wheat (Jing 411) and rice (Shan-you 63). It was observed that the transient increase in chlorophyll fluorescence after the termination of actinic light was increased and the half-time of re-reduction of P700〓 was shortened in both rice and wheat leaves, indicating that cyclic electron flow around PSI was accelerated by NaHSO〓 treatment.

为探究NaHSO〓促进高等植物光合作用的机理，我们研究了NaHSO〓对小麦（京411）和水稻（汕优63）围绕PSI的循环电子传递影响，实验发现低浓度NaHSO〓可促进小麦和水稻叶片的叶绿素荧光在作用光关闭后的短时上升以及缩短叶片在远红光后P700〓再还原的半时间，表明NaHSO〓可以促进小麦和水稻的围绕PSI的循环电子传递。

We analyzed the air gun signals in the 185Km-long seismic line. And the records showed that the air gun signal is full of seismic phase information. Based on these phases, we developed the P-wave velocity model for this area and find an obvious low-velocity layer, which is coherent to what people obtained from other geophysical methods in this area.

我们分析了气枪激发信号在长185km测线上的记录，拾取包含的丰富震相信息(如Pg，Pn，PmP等)，并在此基础上反演了该地区的P波速度模型，模型结果显示该地区存在明显的低速层，这与在该地区进行的其他地球物理探测结果一致。
