在8%、12%、16%浓度下，赤藓糖醇培养基的A值较木糖醇培养基低，pH值较木糖醇培养基高，说明变异链球菌在含8%、12%、16%赤藓糖醇的培养基内的生长和产酸能力明显较相同浓度木糖醇培养基低。

The data of pH were lower in 0.5%, 1%, 2% erythritol culture medium than in xylitol culture medium at the same concentration, while higer in 8%, 12%, 16% erythritol culture medium than in xylitol culture medium at the same concentration.

结果 在0.5%、1%、2%浓度下，赤藓糖醇培养基的A值较木糖醇培养基高，pH值较木糖醇培养基低，说明变异链球菌在含0.5%、1%、2%赤藓糖醇的培养基内的生长和产酸能力明显较相同浓度木糖醇培养基高。

Results:Part1: Mean serum EPO concentration of CRF patients showed significant lower than that of control. After transplantation, renal function recovered quickly while Hb level increased steadily in 37 patients with immediate graft function. Their EPO concentration increased significantly and double peaks of EPO level were obtained at day 4 and week 4. 4 cases in IGF suffered from post-transplant erythrocytosis. But their EPO concentration did not reach statistical significance. 5 cases developed delayed graft function, without EPO double peaks and their EPO concentrations showed signiffcant lower than that of IGF.

结果：第一部分：尿毒症病人血清EPO浓度明显低于正常对照值。37例立即肾功能恢复者，SCr迅速下降，Hb上升，其血清EPO浓度在术后第4d形成第一个高峰，与术前和正常对照比较均有显著差异，其后开始下降，在术后4w时再次升高形成第二个高峰。4例IGF患者在术后16w左右发展为PTE，其EPO浓度值略增高，但与IGF组患者EPO水平无统计学差异；5例DGF患者术后无典型的双峰特点，EPO水平明显低于同时期IGF组，直到肾功能恢复后才逐渐升高。

By changing the temperature, the ethylenediamine concentration, pH value and SO2 inlet concentration, and the impacts on the SO2 removal efficiency were investigated.

通过改变吸收剂温度、乙二胺浓度、吸收剂pH和SO2进口浓度，探讨其对脱硫率的影响。

Three species of typical fresh algae, Chlamydomonas reinhardtii, Euglena gracilis, Synechococcus leopoliensis, were chosed as the experiment material in order to investigate their biodegradable abilities to triazophos.

使用液液萃取——气相色谱检测的方法测定培养基中三唑磷的浓度，回收率在84.2%～97.4%之间，相对标准偏差为0.24%～2.48%；藻培养液离心后取上清液用液相色谱检测培养基中三唑磷的浓度，回收率为99.0%～99.7%，相对标准偏差为0.6%～1.0%。

And the influence factors such as suspension concentration,operating pressure,Reynolds number and Euler number were established.

结果表明，死端过滤速率衰减模型中过滤速率与时间呈幂函数关系、而十字流过滤速率衰减模型中过滤速率与时间则呈一次函数关系，死端过滤时悬浮液浓度和气压过滤压力对其过滤速率衰减模型系数的影响均呈三次函数关系，在十字流过滤时悬浮液浓度、操作压力以及雷诺数对模型系数b的影响均呈线性关系，轴向流十字流过滤速率衰减模型系数b与欧拉数呈反比，而旋转流十字流过滤时则模型系数a与欧拉数呈反比关系。

The result shows that explants of Rheum will die when the concentration of europium chloride is 100 mg/L.

实验结果表明，低浓度氯化铕促进愈伤组织生长，高浓度则抑制生长，浓度达到100 mg/L则可导致大黄外植体全部死亡。

The optimum experimental conditions were as follows: the excitation and emission wavelengths of the complex were 332 nm and 618 nm, respectively, pH=7.5, the concentration of europium ion was 1.2×10^(-5) mol/L, the surfactant concentration of SDBS was 3.0×10^(-5) mol/L.

最佳测定条件为：最大激发和发射波长分别是332和618 nm；pH=7.5；Eu(上标 3+)浓度为1.2×10^(-5) mol/L，SDBS浓度为3.0×10^(-5) mol/L。

Morphological observation showed that exposure of≥0.625 mmol/L Na2SO3 could decrease cell numbers significantly and living cells seemed narrower and longer than the usual way with fewer evection. But lower concentrations of Na2SO3 (≤0.156 mmol/L) did not change cell numbers and cell morphology.

形态学观察发现，当接触亚硫酸钠浓度≥0.625mml/L时，细胞数量明显降低，细胞比较细长，突起较少；当亚硫酸钠浓度簇0.156mmol/L时，细胞数量和形态基本无变化。

The matrix differential equation is solved using method of steps and applying Laplace transform. Using this method and exact solution of the matrix differential equation with delayed arguments was....
