The X_ray diffraction patterns of the samples show that the relative intensity of (110) peak increases with increasing pressure, which implies that pressure has the orientation effect on the CrO_2 needle-shaped nanoparticles.

样品的X射线衍射结果表明(110)峰的相对强度随压力的增加而增大，说明压力对CrO2针状纳米颗粒有取向的作用。低温时CrO2样品的电阻和磁阻均随压力的增加而减少。

Since the y -ray's self-absorption of radiate materials is a very important factor, which depends on the geometry of the materials.

而其中γ射线的自吸收，是影响谱线分杉析精度的一个极为重要的物理量，它与放射性核材料的几何尺寸有密切的关系。

Sandy uroliths' in bladder and sigmoid flexure were clearly diagnosed with helical CT. At the same time, the location, size and shape of sandy urinary stones were satisfactorily found with intravenous X-ray radiology, B-mode ultrasonogram and helical CT. These results showed combined three methods in clinics were a fast precise methods to diagnose urolithiasis.

因此B超、螺旋CT和X射线腹部平片不仅对饲喂棉饼诱发的山羊砂石样结石有明确的诊断，而且可以方便地观察到结石的位置、大小、形态，三者的结合有利于对山羊砂石淋的快速、准确诊断。

The calculational results are in good agreement with the X-ray data and show that different substitute group results in different charge distribution, the exocyclic sulfur atom has the biggest negative charge value and this site is the most likely site of protonation and methylation as well as the potential coordination site with metallic ions.

计算结果与X-射线衍射数据相符合，并显示虽然不同的取代基导致了不同的电荷分布，但四唑环外的硫原子总是具有最大的负电荷分布，从而使其成为最有可能的质子化、甲基化及与金属离子进行反应的点位。

They cannot detect a nonwetted joint if the correct volume of solder does exist in the path of the beam, even if there is a gap between the solder on the lead and the solder on the land.

他们不可能查出一个不潮湿的联接，如果焊剂的正确容量存在于射线的道路，即使有焊剂在主角和焊剂之间的一个空白在土地。

In this paper, the functions and the fashions of regularization are discussed when traveltime tomography is reduced to the solution of linear equation system, the functions of regularization include: constraint components which are underdetermined or lie in null space using overdetermined components and all kinds of known information; treat the uneven coverage of rays and the inaccurate datas by damping.

反射地震走时层析最终可归结为线性方程组的求解，本文讨论了在线性方程组求解过程中正则化的作用和方式。正则化的作用有：(1)用超定分量约束欠定分量和零空间分量；(2)用先验信息约束欠定分量和零空间分量；(3)对射线的不均匀覆盖进行阻尼；(4)对数据的不准确性进行阻尼。

Compared with non-nanopolyaniline synthesized by conventional emulsion polymerization, nanopolyaniline has the narrow and uniform distribution of particle dimension and the diameter of particle is about 4-5nm,and the conductivity reaches 3.2S·cm-1, which is more than 100 times higher than that of nanopolyaniline;Moreover, it has higher solubility in conventional solvent and the solubility reaches 95% in N-methyl pyrrolidone;what's more ,it has higher crystallinity and more uniform crystal proved by XRD, apparent blue shift indicated by UV, which makes it possible to prepare transparent conductive composite films.

结果表明，微乳液法合成的纳米聚苯胺与常规乳液法合成的非纳米聚苯胺相比，具有明显的优越性：粒径分布窄，95%的在10nm 以下，最大的不超过30nm；电导率较高，达到了3.2S/cm，提高了2 个数量级以上；在有机溶剂中的溶解度较高，其中在N-甲基吡咯烷酮中的溶解率达到了95%；X 射线衍射仪分析表明，纳米聚苯胺结晶度高，晶型更为规整；紫外可见光谱研究发现，纳米聚苯胺在可见光区有明显的蓝移，为制备透明的导电复合膜提供了可能。

Parviflora in shrub communities had the xeromorphic traits in the aspects of ① their secondary xylem had shorter vessel elements, higher vessel frequency, less single porous percentage, lower rays, higher relative conductivity and lower vulnerability index, and ② their leaf had lower water potential, lower water content and free water content, higher bound water content, high ratio of bound to free water content, and less specific leaf area.

扁担木叶片、次生木质部的解剖和水分生理特征均表现出一定的可塑性，其可塑性指数高低顺序为次生木质部解剖特征（0、24）〉水分生理特征（0.19）〉叶片解剖特征（0.18）、与侧柏林和混交林相比，灌丛中扁担木个体对干旱生境有一定的适应能力，表现在次生木质部导管分子短，导管频率高，单孔率低，木纤维短，射线矮小，具有较大的相对输导率和较小的脆性指数；叶片水势、组织含水量、自由水含量较低，叶面积、比叶面积较小，而束缚水含量、束缚水自由水比值较高。

This has an important meaning to the industrial manufacture.DSC, WAXD and polarizing microscope with hot stage experiments were performed to describe what led the SSP rate acceleration of PET/MMT. It was shown that montmorillonite acted as a very good nucleating agent in PET crystallization process, which results in the lower crystallinity, more small microlites, and more surfaces of microlites.

为研究PET／MMT固相缩聚效率提高的原因，通过热台偏光显微镜、DSC、X-射线衍射等手段对样品的结晶进行观察与分析研究，结果表明蒙脱土对PET的结晶有明显的成核作用，使其晶核生成速率迅速提高，晶核数量明显增多，从而使整个结晶过程的时间变短，同时形成了更多结构不完善的微晶体。
