研究结果：其中患有腰突的5位患者在怀孕期间接受了部分髓核摘除术和椎间盘全摘术并且未影响生育。

The photocatalytic degradation rate of heptene increased with increasing the initial concentration of sulfur dioxide, but maintained almost a constant beyond a certain concentration.

同时研究了庚烯和二氧化硫的初始浓度、氧气和水蒸气的不同含量及光强等因素对其光催化氧化降解的影响。

The solid product was characterized by N2 adsorption-desorption, XRD, TEM and hydrothermal stability test. These results indicated that small amounts of HPMo in the synthesis media could reduce the amount of liquid in-organic acid and crystallization time greatly. And SBA-15 sieves prepared in this method exhibited an excellent hydrothermal stability, as its hexagonally ordered mesostructure was maintained after treated in 100 ℃ water over 72 h.

N2吸附-脱附、XRD、TEM和水热稳定性实验等检测结果表明：用这种方法不仅可以大幅度降低合成SBA-15分子筛所需液体酸的用量和缩短晶化时间，同时反应产物SBA-15在100 ℃的水中处理72 h后仍然保持六方有序的介孔结构。

It is imperative that constant force be maintained between the extrusion and hyalinization phases; otherwise, the desired orthodontic movement will not take place.

当务之急是保持恒定力量之间的挤出和透明的阶段，否则，所期望的矫正运动不会发生。

Vallisneria spinulosa maintained high levels of genetic variation both at the species and at the population level. Partitioning of genetic diversity revealed a surprisingly low population differentiation as compared to other hydrophilous angiosperms.

利用等位酶和开发的微卫星标记研究了刺苦草在长江中下流域的遗传多样性和遗传结构，研究结果表明，刺苦草在居群水平和种水平都具有高的遗传多样性；居群间遗传分化程度非常小；居群间历史上存在长距离基因流。

The inter domain information retrieval technique is illustratively based on a request/response signaling exchange whereby at least a portion of the reachability, i.e., routing, information maintained by the target node is propagated to a head-end node of the TE-LSP.

域间信息取得技术例如基于请求/响应交换，从而目标节点所维护的至少一部分可达性信息被传播给TE-LSP的头端节点。

Then it examines in what way the immensurability of values that exists among different cultures determines how different models of good governance may be plausibly maintained in different cultures.

然后文章将考察存在于不同文化中的种种价值观之间的不可公度性是以什么方式规定下述情况的：在不同文化中，良好治理的不同模式是有理由维系下去的。

Rodent incisors are known to be continuously growing teeth that are maintained by both the cell-proliferation at the apical end and the attrition of the incisal edge.

啮齿动物的切牙终生不断生长，其高度通过切端磨损及根尖末端的细胞增殖来维持。

The distribution of N-P and the moisture variation caused by incrassation of the mattic epipedon together with its relationship to pasture degradation by grazing in alpine Kobresia meadow were studied at the Haibei ecosystem research station, Chinese Academy of Sciences. From 2005 to 2007, the plot pasture was maintained with a relatively stable grazing intensity and had formed obvious differences in surface character and species component.

在中国科学院海北高寒草甸生态系统研究站地区，选择了5个自然放牧梯度、处于4种典型退化阶段的高寒嵩草草甸为研究对象，进行了土壤草毡表层加厚引起的系统氮、磷分配和水分利用的变化过程研究。

The rough set required that discretization should be maintained indiscernibility of the original decision-making system, however, many algorithms before permitted approximate quality descended controlled certain scope.

粗糙集理论中要求离散化保持原有决策系统的不可分辨关系，但以往的一些算法在离散过程中会使近似精度控制在可以接受的范围，即允许一定的错分。

When this condition occurs, inbound replication with the source partner is stopped on the destination domain controller and event ID 2042 is logged in the Directory Services event log.
