根的

The number of bacteria, fungi, ammonifier and nitrobacteria were positively correlated with the biomass of growing roots and absorbing roots, while the number of nitrogen-fixing bacteria was negatively correlated with absorbing root biomass.

细菌、真菌、氨化细菌和硝化细菌数量与生长根和吸收根生物量之间显著正相关；固氮菌则仅与吸收根生物量显著负相关；而纤维素分解菌与根系生物量的相关关系不显著。

Objective To evaluate the influence of root canal and apical conditions on the accuracy of an electronic apex locator.

目的 探讨根尖炎症及根管干、湿状态对电测法测量根管工作长度准确性的影响。

He, however, insists on keeping focused on Burgundy."Things in Burgundy keep me busy enough; moreover, I am a Burgundian."

Erwan Faiveley却认为长袖难舞，"布根地已经够我忙了，我的根在布根地"。

In practice, this is because just before the out of teeth, root is not fully formed, the pulp cavity and apical foramen are large, thin apical cementum caused.

实际上，这是因为之前出牙，根尚未完全形成，牙髓腔和根尖孔大，薄根尖牙骨质造成的。

Mastery the method of root canal treatment, includeing method of root canal preparation (standardized system, step-back technique, step-down technique) and root canal condensation technique, principle , operation, incidental problem in the operation course of every kind endodontic treatment method

掌握根管治疗的操作方法，包括根管预备方法（标准法，逐步后退法，冠根向深入法）和根管充填方法，各种牙髓治疗方法的原理、适应症、操作方法及操作过程中容易发生的问题

Can, under the guidance of the teacher, the correct file to use root canal + protaper, prepared root canal, the sharp taper gutta-percha filling + fiber post + crown restoration or filling operation, the independent number of cases completed root canal therapy and filling.

能够在老师的指导下，正确运用根管锉＋protaper，预备根管，大锥度牙胶尖充填＋纤维桩＋冠修复或充填术，独立完成若干例根管治疗及充填术。

D after setting, the fresh root weight and dry root weight of IC3 were 8.63 and 0.35g, respectively, which increased by 9.30% and 5.67% compared with the control (without plastic pipe and plastic pot) and the difference reached significant level; CO2 concentration of root rhizosphere of cucumber on IC3 was 0.309% at 13:00, which reduced by 29.4% compared with the control.

定植后13d， IC3处理黄瓜的根鲜重、根干重依次为8.63， 0.35g，比对照分别增加了9.30%和5.67%，差异达显著水平；在13：00时，IC3处理黄瓜根际CO2含量为0.309%，比对照降低了29.4%。

This trend was obvious for 5-year-old plantation. The biomasses of living and dead fine roots at 0~10cm accounted for 51.9% and 53.3% of the totals, respectively. The 84.6% of living and 82.8% of dead fine roots concentrated at the depth of 0~30cm.

在0~10cm土层中的活、死细根生物量分别占全部活细根生物量的51.9%和死细根生物量的53.3%，活细根生物量的84.6%和死细根生物量的82.8%分布在0~30cm的土层中。

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。

At growth period of Moso bamboo, because the root has not grown completely and has little influence on rhizosphere soil, so the score was the highest. The score of rhizosphere soil decreases as the growth and root gradual development of Moso bamboo. The rhizosphere soil quality increased at later stage of Moso bamboo because of gradually weakened growth and the increased litter and microorganism activity.3.The demands for nutrients of Moso bamboo at different growth periods were different. It was different in the demand for nutrients of Moso bamboo at different growth period.

成竹期由于根系未完全形成，对其根际土壤的影响较小，因而成竹期得分最高，随着毛竹生长，根系渐渐发达，对其根际土壤的影响日渐扩大，造成根际土壤得分渐低，后期毛竹生长逐渐减弱，对其根际土壤的影响也随之减少，加上林中凋落物的增加和微生物活动增强，其根际土壤的质量有所增加。3、不同生长阶段毛竹对营养元素的需求有所不同。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
