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）。

Objective:To study the radiation-induced changes of carcinoma lesion and non-tumor tissues and organs of pelvis in patients with cervical canner on magnetic resonance imaging during and after radiation therapy. Methods:pelvic MR imaging was performed in 36 patients with cervical carcinoma before, during, and after radiation therapy. The size and signal changes of carcinoma lesions and pelvic soft tissues were observed on MR images.

The promotion of baby-friendly medical care hospitals in Taiwan since 1999 has resulted in an increased breastfeeding initiation rate for newborns. After maternity leave, however, employed mothers have found it difficult to continue breastfeeding their babies.

自1999年推广母婴亲善医疗院所后，产妇在住院期间的母乳哺育率已提升；然而产假结束后，对许多职业妇女而言上班后持续哺乳似乎成了不可能的任务。

Within 24 hours of delivery, 16 breast milk samples from mothers of term and preterm infants were divided into aliquots. Fresh samples were immediately tested for antioxidant activity based on their ability to inhibit the oxidation of 2,29-azino-di-3- to its radical cation compared with Trolox, a strong antioxidant that is a derivative of vitamin E. The remaining aliquots were stored at –20 C or 4 C for analysis at 48 hours and at seven days.

在出生后24小时内，研究人员对足月儿及早产儿的母亲取样了16个母奶样品，并作多次的小量分装，新鲜的样品立刻作了抗氧化活力的分析，分析的根据为对2，29-azino-di-3氧化成阳离子自由基的抗性程度，对照品为维生素E的衍生物Trolox；剩下的样品则储存在-20C的冷冻温度下，或4(C的冷藏温度，并於48小时及7天后取出作再试验。

Inside wall steel pipe after tidy up again use to gather the ethylene as lining material to melt to revolve to model a craft to process with the heat but become, make lining material and metals steel intertexture hot to merge into an integral whole, firmly gather knot in wall inside the piping after cool off, so then can batch quantity produce plastics compound steel pipe.

内壁清理后的钢管再用聚乙烯为衬里材料用热融旋转成型工艺加工而成，使衬里材料与金属钢交织热融为一体，冷却后牢固地聚结在管道内壁，这样便可批量生产衬塑复合钢管。

The Raman spectra of the deposited species did not exhibit thespectral feature of buckminsterfullerene, but the hexagonal graphite and the amorphouscarbon in 〓 hybridization instead. The deposited species were desorbed and mass analyzed.

7经质量选择后的直链碳原子簇沉积在HOPG单晶面后改变了其本身的构型，主要以纯碳簇的形成存在，另外也发现相当一部分碳聚集而成芳香环，由于环状构型存在较多悬挂键，氢原子起到了饱和悬挂键的作用。

In optimizing design, there are some contradictions amongst every object of the system;the main object of system and the object of subsystem also have some contraventions as well as the object of every subsystem. Because of those problems, the optimum allocation of the main system cannot be achieved by optimizing every single subsystem;That is to say, the connection of simple optimization is unequal to the complex optimization.

工程系统优化设计中，不但多个目标间存在矛盾、而且系统总目标与子系统目标间及各子系统目标间也存在矛盾，所以各子系统单独优化后所得结果一般说来并不意味着工程系统本身的优化，正像各构件独立优化后凑成的结构并不一定最优一样。

Print, and aspects of the seihan process is an important process of the mesh camera negatives was, the speed of image at high-profile sites transparent, to take 3.5 MW to 750 MW, 4.5 become positive exposure after dot 3% or more low key parts of the image xiaohei point 0.5 to 1 captured the idea to become dark circle, you must have tried small solid reflective point after desensitising cannot be displayed.

晒版是铜版制版工艺的一个重要工序，它对网目照相的底片要求非常严格，一般要求图像高调部位网点透明，要拍摄到3.5～4.5成为宜，晒版后阳图网点在3成以上，图像低调部位小黑点拍摄到0.5～1成为宜，点子要黑要圆，必须照足细小坚实的反光点，以便版面腐蚀后能显示层次。
