Inwheat intercropped with soybean not only N situation could be improved butalso P situation could be.2In intercropping,the pH of soybean rhizospherewas decreased by increasing the R-Apase activity,which could decelerate thetransforming and fixing P fertilizer.3In both monoculture and intercroppingsystem,the soil pH of rhizosphere was affected by cropping system at two Plevel which only 0.1-4mm distance from the root surface,but the effect of S-Apase activity in the rhizospher soil by cropping system was less than3mm.In effect,the rhizosphere P was really available nutrient,and applyingP to rhizosphere was effective ways to reduce the P nutrient competition.4Inwheat/soybean intercropping,the peak stage of reduction ability of roots wasthe same as that of the root growth,so that the time compensation appearedin intensity of nutrient absorption.

间套作大豆、小麦、玉米根系Apase的差异又反映出大豆利用土壤磷的潜在能力最大，而玉米最小，可见禾谷类的小麦与大豆间套后不但能改善小麦的氮素营养状况还使磷素营养也得以好转。2）间套大豆根际pH值的下降，导致磷肥施入土壤后形成〓-P的比例显著提高，转化成〓-P等难溶性磷减少，说明间套的大豆能减缓肥料磷在土壤中的转化和固定，减少磷素向无效化方向转化。3）复合群体根际土壤pH值的影响一般只发生在0.1-4mm的根际微区，而土壤磷酸酶的影响供磷与否在距根表3mm以外都无多大差异，说明根际磷才是真正有效磷，根际施磷是解决磷素竞争的有效途径。4）。

The average contents of available sulfur in soil and sulfur in tobacco leaf from tobacco-rice continuous cropping pattern were 39.06 mg/kg and 0.968%,and 30.42 mg/kg and 0.704%for single cropping in dry land respectively.

烟叶硫含量仅有30%在0.20～0.70%正常范围内，70%烟叶硫含量超标，尤其是浏阳和宁乡植烟区的烟叶硫含量超过了1.00%。

A multi-channel representation of the input image was obtained by a bank of Gabor filters, corresponding to multiple scales and multiple orientations. Full-wave rectification of each channel and contrast gain control among the channels were performed sequentially to get orientation feature maps with multiple scales and multiple orientations.

从输入图像出发，采用Gabor算子建立多尺度、多方位的多通道图像，通过全波整流和各通道间的对比度增益控制，得到多尺度、多方位的方位特征图，这些特征图的线性组合则为显著性图。

In real flight, multiple sensors of aircraft engine control system may fault at a time. In order to solve this problem, a revised multiple-failure-hypothesis based testing is investigated. This approach uses multiple Kalman filters, and each of Kalman filter is designed based on a specific hypothesis for detecting specific sensors fault, and then uses WSSR (Weighted Sum of Squared Residual) to deal with Kalman filter residuals, and residual signals are compared with threshold in order to make fault detection decisions. The simulation results show that the proposed method can be used to detect multiple sensors soft failures fast and accurately.

一般认为两个以上传感器同时发生故障的概率较小，但实际上不能排除其发生的可能性；提出了一种改进的多重故障假设方法来解决航空发动机控制系统多传感器同时发生软故障的问题，这一方法采用一组卡尔曼滤波器，每个滤波器对应一个被检测传感器的故障模态；采用残差加权二乘方处理滤波残差并与门限值作比较来判断是否发生故障；仿真结果表明，所提出的方法能有效解决多传感器软故障的检测与隔离问题。

The distribution was different in various multiple cavitary lung diseases.Local multiple onset was particularly prevalent in cavitary pulmonary tuberculosis,scattered multiple onset was particularly prevalent in various infected cavitary lung diseases,diffuse multiple onset was particularly seen in cavitary pulmonary metastases.

多发性肺空洞病变的肺内分布形式不同，局部多发多见于结核性肺空洞病变，散在多发多见于感染性肺空洞病变，弥漫多发多见于肺转移瘤空洞。

The patho-factor of pulmonary fibrosis is very complex. With the development of cytobiology and molecular biology there are much proof shows PF is a disease induced by multiple factor, multiple organ and multiple cell; and happens between cells and mesenchyma in multiple path.

肺纤维化(pulmonary fibrosis，PF)形成的病理因素十分复杂，近几年细胞生物学和分子生物学的发展为PF的形成机制提供了大量依据，证明PF是一个多因素、多器官、多细胞、多种因子之间以及细胞与间质成分之间形成的一个多层次，多步骤，多通路的疾病。

They have quite a lot of work to do.
