Phosphorus speciation of forest‐soil organic surface layers using P K‐edge XANES spectroscopy

The phosphorus (P) speciation of organic surface layers from two adjacent German forest soils with different degree of water‐logging (Stagnosol, Rheic Histosol) was analyzed by P K‐edge XANES and subsequent Linear Combination Fitting. In both soils, ≈ 70% of the P was inorganic phosphate and ≈ 30% organic phosphate; reduced P forms such as phosphonate were absent. The increased degree of water‐logging in the Histosol compared to the Stagnosol did not affect P speciation.     

应用（60）Co-γ射线辐射治疗家蚕微粒子病研究

[目的]探索防治家蚕微粒子病的新方法。[方法]利用60Co-γ射线辐射处理微孢子虫、感病家蚕幼虫和蛹及带毒蚕卵,研究60Co-γ射线辐射对家蚕和微孢子虫作用的差异及其对家蚕微粒子病的治疗效果。[结果]以20-160 Gy剂量辐射,不能杀死微粒子,不能去除感病蚕体的微孢子虫。感病家蚕幼虫体重随辐射剂量的增加而降低,感病蚕的死亡率在80 Gy以上处理时有明显增加的趋势。随辐射剂量的增加,辐射处理卵的孵化率降低,孵化蚕的带毒率也有一定程度的降低,孵化蚕和未孵化蚕总的带毒率降低;20-160 Gy小剂量辐射,不能去除蚕蛹体内的微孢子虫。随辐射剂量的增加,蚕蛹羽化率、母蛾带毒率、卵带毒率和雄蛾交配能力逐步降低,但20 Gy辐射处理的蛹羽化率高于对照和其他处理。[结论]低剂量60Co-γ射线辐射对家蚕卵具有一定的除毒效果。     

Soil Reserves of Potassium: Release and Availability to Lolium perenne in Relation to Clay Minerals in Six Cropland Soils from Eastern China

An 8‐month greenhouse experiment with ryegrass (Lolium perenne L.) examined the relationship between the dynamics of potassium (K) reserves in soil and changes in clay minerals, using X‐ray diffraction. The capacity of soil to release K was consistent with its ability to supply it and was the highest in the soil samples collected from Laiyang (H₁T₂a), Harbin (H₁T₁) and Beibei (H₂T₄), followed by the sample from Jiangyan (H₁T₂b), and the lowest in the samples from Gao'an (H₂T₃a) and Wangcheng (H₂T₃b). Removal of soil K decreases the intensity of reflections for illite and increases that for interstratified clay minerals. The centre of gravity values of the clay fractions was significantly negatively correlated to the depletion of soil K reserves, as ascertained through chemical extraction or through plant action. The quantitative regression equations between the centre of gravity values and the dynamics of soil reserves of K can be used for predicting the release and plant availability of K even without growing a crop.

Design method of generatingDICOM Image in the high frequency X ray machine

DICOM3.0 standard is complex and rich in contents. Aiming at the difficulty of software design, a programming method of generating DICOM image file in the high frequency X ray machine is proposed. The data structure of DICOM file is analyzed, and then the programming method of generating DICOM image files is introduced in detail. For the proposed method, a template array of the data structure is constructed to save the eigenvalues, transfer syntax, pixel data and so on of the image. All kinds of the data are stored in the DICOM file successively. The programming method can not only transform a BMP file into a DICOM file, but also transform a JPEG file into a DICOM file. It strictly follows DICOM 3.0 protocol. The generated DICOM files can be displayed with the DICOM file browsing software ezDICOM. The programming design was based on VC++6.0.     

Analysis of cationic elements in liquid samples by x‐ray

Abstract

Plant analyses methods have expanded immensely to document plant mineral element deficiency and toxicity disorders and to note mineral element interactions. Experiments were conducted to determine the feasibility of using cation exchange papers for the extraction of cationic elements from solutions to be analyzed by x‐ray fluorescence. The cationic elements Al, Fe, Mn, Zn, and Cu were effectively extracted from solutions by one exchange resin paper disk if solutions were passed several times through the exchange resin paper. Calcium and Mg were extracted from solutions if two or three separate exchange papers were used, and K was not extracted from solutions with the use of up to five separate exchange papers. The relatively high concentrations of K in solutions and the relatively low exchange capacity of ion exchange resin papers apparently prevented the effective removal of K from solution. The detectability limits on the exchange resin disks by this technique were <2.8 μg Al, 0.5 μg Fe, 0.10 μg Mn, 0.10 μg Zn, and 0.08 μg Cu. Extraction of cationic elements from solutions for x‐ray analysis appeared practical and relatively rapid for Al, Fe, Mn, Zn, and Cu, less practical for Ca and Mg, and impractical for K.
