Proton generated from a Cockroft-Walton accelerator in the energy range of 30-100 keV were appropriately collimated and made to pass through a 10 g/cm^2 carbon foil. After Rutherford scattering, proton uniformly irradiated TLDs which were placed at the 20° behind and 20 cm away from the carbon foil. We used a channeltron behind TLD holder as the proton detector.

The content of mineral elements in ripe fruits of M.sieversii from 78 seedings at Mohe Town,Gongliu Country were analyzed using Atomic Absorption Spectrophotometer.The results indicated that M.sieversii seedings presented considerable genetic variations in content of mineral elements with the range of variation coefficients from 24.2% to 54.0%.So it has large potential for further selection.Four elite seedlings were selected,namely large fruit type,high Ca content type,high Zn content type and high damascenone content.As the predominant component of Ily wild fruit tree forest,Malus sieversii had occupied an area of 9300ha.But the inherent reproduction system of M.sieversii and genetic diversity of the species were destructed in different degrees,as a result of farming assart,over grazing and damage by Agrilus mali.

上述结果支持&新疆野苹果可能是栽培苹果祖先种&的结论；②对巩留县莫舍乡的新疆野苹果78个实生株系果肉组织Ca、Mg、Fe、Zn、Cu、Mn6种矿质营养元素进行测定的结果表明，每种矿质元素含量单株间差异显著，变异系数在24.2％～54.0％，遗传多样性丰富，进一步选择的潜力很大；③根据新疆野苹果果实形态、香味物质和矿质元素含量等的测定结果，初步筛选出了大果型、高钙型、高锌型和大马酮型等4个特异性状单株；④调查发现，由于农田开垦、过度放牧以及苹果小吉丁虫的蔓延危害，目前伊犁野果林面积逐年减少，野苹果固有的繁育体系和遗传多样性受到不同程度的破坏。

It is shown from the assessment results that (1) both the TN and TP fluxes discharged from the Changjiang River to the Changjiang River estuary sea area increased continuedly, the DIN concentration in the sea areas increased continuedly, and the Si concentration decreased continuedly, which resulted in the significant changes in N/P/Si ratios;(2) the chlorophyll a concentration in the sea areas increased continuedly, and the significant changes in community structure of phytoplankton occurred;(3) the species and biomass of benthos declined greatly, and the bottom oxygen-poor water area increased significantly;(4) the range and occurrence frequency of red tide events in the sea areas increased greatly, and the algal toxic infection events of mussel were frequently found in the sea areas.

结果表明，长江向长江口海域输送总氮和总磷通量持续增大，长江口及其邻近海域无机氮浓度持续增高而硅浓度持续下降，并由此导致N/P/Si与比值的显著变化；该海域叶绿素a浓度持续增大，浮游植物群落结构也发生了显著变化；该海域底栖生物种类和生物量都大大减少，底层水低氧区面积也显著扩大；该海域赤潮事件无论是规模还是频率都大大增加，藻类毒素DSP/PSP贻贝传染事件也时有发生。

In addition, AM fungi from a wide range of environmental conditions (originally isolated from north, central and south China) were used to study the ecological adaptability of AM fungi and the influence of edaphic conditions on AM fungal growth and metabolic activity.

丛枝菌根共生体由宿主植物和真菌共同组成，菌根真菌的生长、代谢活性、菌丝分布以及生态适应性等特征不但与菌根效应、菌根真菌的生态功能密切相关，而且受到宿主植物和土壤条件的影响。

The effects of small range of changes of Ca(superscript 2+) and Mg(superscript 2+) concentrations (0-100 mg/L) on the survival rate and growth were studied in the larvae from the mysis Ⅲ(M3) to the postlarval 10 (P10) stages of Litopenacus vannamei. Larvae were raised in artificial water prepared from condensed sea water and tap water.

采用浓缩海水与自来水调配的基础海水，以凡纳滨对虾Ⅲ期糠虾幼体(M3)作为试验对象，在小范围(0~100 mg/L)内调节育苗用水中Ca(上标 2+)、Mg(上标 2+)浓度，以L9(3^4)正交表设计，研究育苗用水中不同Ca(上标 2+)、Mg(上标 2+)浓度对凡纳滨对虾M3育成仔虾(P10)的成活率和生长的影响。

Two construction methods for fewer views from limited range—ART and SART are studied, and simulated a physical fields views whose variation of deflection is equal to double-Gauss function, and then reconstructed it, and still analyzed the accuracy of the reconstruction methods.After study and analysis on the theory of ART and SART, and after analysis the properties resulted from their theory root cause, A modified simultaneous algebraic reconstruction method is presented, which is based on ART, this method takes into account both the pixel itself and the pixels close by it which are crossed by the same ray.

论文研究了两种有限投影方向的非轴对称场的CT重建算法——代数重建法和联合代数重建法，并用VC++程序模拟实现了折射率分布为双高斯函数的场的正向投影及重建过程，并对所用算法的重建精度进行了分析。

A practical charged membrane which prepared from the blends of sulphonated polyphenylene sulfide/poly can be considered as a 3D lattices. The experimental conductivity was related with a 3D simulation and the result showed the membrane has a transition from insulator to conductor at the ratio of charged components SPPS about 0.144. Obviously, this value falls in the range of a theoretical simulation for a 3D lattices.

由於实际的荷电膜也可看作为三维格栅体系，因此，可用三维格栅体系程序对不同荷电分率膜的电导数据进行拟合，结果表明，对於实际的磺化聚苯硫醚／聚醚碸共混膜，当荷电组分SPPS的分率达到0.144时，共混膜即会从不良导体变为良导体，显然该值落在理论值0.1~0.2，因此，理论模拟结果与实际荷电膜传质的实验数据相吻合。
