年的茶园，连续5 年研究了施用钾肥对茶园土壤钾库及钾素平衡的影响。

The results showed that the three straight lines model could fit the soil shrinking and swelling characteristic curves well. The characteristic values of the curves were smaller than 1. This indicated that during the processes of soil swelling and shrinking, the change of the soil specific volume was smaller than that of the soil water content. Values of the geometry factors of four soils studied were equal to 1 at the beginning of shrinking, less than 3 and greater than 1 at other swelling-shrinking phases. The geometry factor values in different phases showed that soil swelling-shrinking was anisotropic and only subsidence occurred at the beginning of shrinking.

结果显示：三直线模型能够很好地拟合4种土壤的收缩、膨胀过程；土壤收缩、膨胀曲线各段的特征值均小于1，这说明土壤胀缩过程中土壤容积的变化速率小于含水量的变化速率；4种土壤胀缩过程中几何因子r大于1而小于3，且收缩初期几何因子r等于1，表明土壤的胀缩是各向异性的，并且在土壤收缩的最初阶段只有垂直收缩。

In view of this phenomenon this thesis suggests that the placement of soil nailing forms the soil arching in the soil-nailed wall. This function can be described by Tezaghi's stresstransfer theory. It is the stress transfer that decreases the vertical stress of soil and increases the soil's self-stability and its bearing capability.

针对这一现象，本文认为土钉的设置在土体中形成了土拱作用，这种作用可以用太沙基应力传递理论来描述，正是由于应力的传递减小了土体所受的垂直应力，提高了土体自稳性及承载能力。

The resulted that there was an obvious rhizosphere effect in all growing years of Caranaga microphylla plantation. The pH value of rhizosphere soil was lower than those of near rhizoshphere soil at different growing years. The content of organic matter, total N and available K in rhizosphere soil were all higher than those in near rhizoshphere soil, but the content of Olsen-P in 5-age plantation was remarkably deficient in rhizosphere soil.

对不同生长年限的小叶锦鸡儿人工灌丛根际土壤变化规律研究表明，根际土的pH均小于根外土：土壤有机质、全氮、速效钾在根际土中均有一定程度的富集现象；而5年生的小叶锦鸡儿根际土的有效磷含量出现了亏缺。

The 19th article in the construction and production process of soil erosion caused by not govern, unable to control their own or take soil and water conservation program approved by the management of the unit or individual, should be assessed on its soil and water conservation program or a plan to control the cost of staging the Soil and water administration departments to pay fees to combat the loss of buried by soil and water conservation administrative department in charge of management of the organization.

第十九条在建设和生产过程中造成水土流失，不进行治理、无力自行治理或未接批准的水土保持方案进行治理的单位或个人，应按其水土保持方案的计划治理费用一次或分期向水土保持行政主管部门缴纳入土流失防治费，由水土保持行政主管部门组织治理。

Oxalic acid loading substantially stimulated soil P release from A1 horizon, showing a linear relationship; but its effect on B horizon soil was relatively negligible, especially at low oxalic acid concentrations mmol L^(-1. Oxalate solutions 0.5~20.0 mmol L^(-1 oxalic acid adjusted to pH 5.16 with 10.0 mmol L^(-1) NaOH had a much higher (1.51~2.98 times) soil-P-release effect than oxalic acid solution the same in oxalate concentration. Therefore, the mechanism of oxalic acid/oxalate triggering release of soil phosphorus is assumed to be dominated by ligand-exchange or complexing reactions of oxalate anionC2O(superscript 2- subscript 4 but not simply acid-dissolving effect. The effect of oxalate anion on soil phosphorus release was found to be somewhat cumulative, i.e. the amount of P released was primarily controlled by the cumulative oxalate loading rate, relatively independent of the manner of oxalate addition (one-time or sequential).

结果表明，草酸能显著促进暗棕壤A层磷的释放，土壤磷溶出量随草酸溶液浓度升高而线性增加；但对B层土壤磷的释放效应相对较弱，草酸浓度低於5mmolL^(-1)时B层磷的释放不明显。pH5.16草酸钠溶液比相同浓度的草酸溶液具有更高的解磷效率，在设置二者浓度为0.5~20.0mmolL^(-1)时，前者的解磷量是后者的1.51~2.98倍，推断草酸盐溶液或凋落物淋洗液中草酸类物质促进暗棕壤磷释放的主要机理在於草酸阴离子C2O(上标 2-下标 4配位反应。

The chief authorities for the Gallican Mass are the letters of St. Germanus of Paris (555-576); and by a comparison of these with the extant Sacramentaries, not only of Gaul but of the Celtic Rite, with the Irish tracts on the Mass, with the books of the still existing Mozarabic Rite, and with the descriptions of the Spanish Mass given by St. Isidore, one may arrive at a fairly clear general idea of the service, though there exists no Gallican Ordinary of the Mass and no Antiphoner.

首席当局对大众的高卢圣信街Germanus的巴黎（ 555-576 ）；和比较这些与现存Sacramentaries ，不仅是高卢人，但凯尔特人队的礼仪，与爱尔兰村组群众与书籍，仍然存在摩沙拉仪式，并与说明西班牙大众给予的圣伊西多尔，人们可以得出一个相当明确的总体思路的服务，但不存在任何高卢圣普通群众，没有

PartⅡDiffusion-weighted MR Imaging of breast mass and non-mass lesionPurpose:To evaluate Diffusion-weighted MR Imaging of breast mass and non-mass lesion in lesion characterization by comparing ADCs of malignanty with benignancy.

第二部分磁共振扩散加权成像在乳腺肿块性病变和非肿块性病变中应用价值的对比研究目的：对比乳腺良、恶性病变的表观弥散系数(apparent diffusioncoefficient，ADC)，探讨DWI在乳腺肿块性病变和非肿块性病变中的诊断价值。

Materials and Methods:236 pathology-confirmed breast lesions(155 malignanty,81 benignancy) and 221 disease-free contralateral breast tissues were examined using EPI-DWIb values=0,1000 s/mm~2TR/TE=8400ms/93.8ms; FOV=30×30cm;matrix=128×128;ASSET=2,slice thickness=4mm.DCE-MR imaging was also performed for accurate location of the lesion using VIBRANT sequence.The mean ADC values of malignant and benign lesions and the disease-flee contralateral breast tissues were calculated from the ADC map for each patient.One-way analysis of variance was applied to compare the mean ADCs of malignant lesions with benign lesions and disease-flee contralateral breast tissues.The threshold ADC value for malignant lesion was determined using a receiver operating characteristic(ROC curve analysis.Each lesion was classified into two major types:mass and non-mass lesion.The diagnostic performance of DWI was compared in breast mass and non-mass lesions.Results:155 malignant and 81 benign lesions were confirmed in 236 lesions.

材料与方法：搜集术前行乳腺MR检查并经穿刺或手术病理证实的236例乳腺病变，以对侧正常乳腺腺体作为正常对照，采用横轴位的平面回波-扩散加权成像序列，TR=8400ms，TE=93.8ms，层厚=4mm，激励次数=2：视野=30×30cm，矩阵=128×128，ASSET=2，b值=0和1000s/mm~2；参考动态增强图像准确定位，测量病变区和对侧正常乳腺腺体的ADC值，应用t检验比较良、恶性病变及正常腺体ADC值的差异，采用接收者工作特征曲线(receiver operating characteristic curve，ROC)确定良恶性病变的ADC界值；根据BI-RADS MRI将乳腺病变按照形态学表现分为肿块性病变和非肿块性病变两组，比较ADC值在肿块和非肿块性病变中定性诊断的效能。

Results the risk for developing gestational diabetes mellitus was increasing with growth rate of pregnant body mass index (or=89.1274,95%ci6.2574～95.1757),pre-pregnancy body mass index (or=8.1826,95%ci7.1804～41.3126) years of age(or=2.4322,95%ci2.2815～15.2251) and having family history of diabetes(or=4.1254, 95%ci 4.0247～27.2024),but no statistical difference was observed in pre-pregnancy height.the faster women' s growth rate of body mass index in duration of increase pregnancy,the more possible who would fall in ill with gestational diabetes mellitus.conclusion the incidence of gestational diabetes mellitus was related to the growth rate of pregnant body mass index.

结果 多因素回归分析显示，孕期体质指数增加大(or=89.127？4，95％ci=6.257？4～95.175？7)、孕前体质指数大(or=8.182？6，95％ci=7.180？4～41.312？6)、有糖尿病家族史(or=4.125？4，95％ci=4.024？7～27.202？4)、年龄大(or=2.432？2，95％ci=2.281？5～15.225？1)均增加孕妇发生妊娠期糖尿病的风险；未发现身高与妊娠期糖尿病发病有关。排除孕前体重干扰后，孕期体重增长速度越快，发生妊娠期糖尿病的风险越大。结论孕期体质指数增长过快是妊娠期糖尿病的独立危险因素。
