3The heat transfer in the charging and discharging process are unsteady, and the heat transfer capability of the system will change against time, and the charging rate and discharging rate decreases gradually with time, as should be noticed in the design.

蓄冷和放冷过程都是非稳态传热过程，整个过程中系统的传热能力是不断变化的，蓄冷率和释冷率都是逐渐降低的，在蓄冷设计时应该注意到这点。

Among the copper-bearing IUDs,copper T and copper uterus-shaped IUD took the major lead.

近 2 0年来，随着新型活性IUD逐渐推广应用，IUD的使用种类发生了很大变化。

Some drought-resisting indices were observed in the condition of controlling water supply artificially on potted planting Ceratoides, the results as follows. Leaf water content was gradually decreased with the drought stressed days increasing. In the stressed period, the decrease of C.arborescens's leaf water content was more than that of C.lanata.

试验通过盆栽控水的方法进行各指标的测定，经过分析，结论如下：叶片含水量和相对含水量随着胁迫天数的增加而逐渐减少，胁迫期间，华北驼绒藜的降幅明显低于绵毛优若藜，前者在胁迫期间变化平缓，后者下降幅度较大，不同处理天数间存在明显差异。

A study has been made of the influences of some factors types and concentration of coagulants, etc.

在沉积过程中凝胶浓度起始稍高，随后逐渐下降至一定程度后又缓慢上升，凝胶性能也有类似的变化。

However,the concentration of complexing agent can change the Surface morphology of the coating and the plating rate and affect the microstructure of the coating.

一般认为镀层的结构形态是随含磷量而变化的，即随着含磷量的增加，逐渐由晶体形态Ni的过饱和固溶体过渡到非晶状态，当重量比超过

Results The expression of Foxo3a, Bim, FasL in oocyte nests and primordial follicles were detected in the nuclei and cytoplasms of some oocytes. The patterns of Bim and FasL positive rates were consistent with that of Foxo3a and TUNEL positive oocytes rates, which reached the peak in the ovaries of 2-day-old rats.

结果 免疫组化显示Bim和FasL都在新生大鼠部分卵母细胞巢和原始卵泡的卵母细胞核内和胞浆高表达，且阳性率曲线都在2d达到高峰，随后逐渐降低，与TUNEL和FoXo3a的阳性率变化曲线一致。

Methods The astrocytes were isolated from cerebral cortex of neonatal rats which are born within three days, cultivating by DMEM media added with 15% fetal calf serum and depurating by swinging and passaging, to simulate nulli-nutrition model by substituting medium for PBS buffer solution 3h then applying methylprednisolone and recnutrition immediately, we will go on culturing for three days, verificating astrocytes by immunofluorescent technique; detecting activity of AST; determining GFAP of change by PCR.

采用出生3d内的SD大鼠的新生鼠的大脑制成细胞悬浊液后，应用含15%胎牛血清的DMEM培养液中培养，通过摇床和逐渐传代纯化星形胶质细胞，通过PBS缓冲液代替培养基模拟缺营养模型3h后即刻应用甲基强的松龙(10umol/l)，然后继续培养3d，免疫荧光技术鉴定星形胶质细胞；MTT法检测细胞的增殖活性和凋亡；PCR技术测定细胞GFAP表达的变化。

Digital simulation results show that when a step change in firing angle occurs, the first positive half-cycle time of VC will change suddenly and the subsequent electromagnetic transients appearing in the TCSC circuit will lead to overshoot and oscillations in the TCSC impedance. The range and duration of the oscillation will depend on the synchronization modes used and the manner in which the step change is introduced.

发现脉冲触发角阶跃变小时，电容电压的周期时间也突然变小，使得TCSC的导通角不会随着触发角的阶跃变化而发生突变，而是经过一个振荡过程逐渐达到稳态值，进一步揭示了电容电压同步方式下阻抗阶跃特性会出现过冲和振荡现象的原因。

The results showed:(1)Nitrogen addition changed the soil physical and chemical properties, enhancing the content of NO3—- N available resources in the soil, increasing the plants height and cover, reducing the vegetation light penetration. With increasing of N addition, both the species richness and the diversity decrease sharply (P 0.001).(2)N addition increased the aboveground biomass significantly (P 0.05). With increasing of N addition, the aboveground biomass increased first then decreased, and the grasses biomass increased while the forbs and legumes biomass decreased.(3)There was a significant linear positive relationship between species richness and vegetation light penetration (P 0.05), and also between aboveground biomass and soil NO3—- N content (P 0.05). The relationship between aboveground biomass and species richness was negative upon enhanced N supply.

结果表明：（1）氮素添加提高了土壤中NO3—- N等可利用资源的含量，增加了植物群落植被的盖度，减小了植被的透光率，随着施氮量的增加群落中物种丰富度显著降低（P 0.001）；（2）氮素添加显著改变了植物群落地上生产力（P 0.05），随着施氮量的增加地上生产力呈现先增加后降低的变化趋势，各功能群中禾草生物量显著增加，而杂草和豆科生物量随施氮量增加逐渐减少；（3）物种多样性与植被透光率呈线性正相关（P 0.05）；地上生产力与土壤NO3—- N含量呈线性正相关（P 0.05）；随着施氮量的增加物种丰富度与生产力之间呈负相关关系。
