The levels of sCD23 were not significantly different between the different kinds of dialyzer in reuse group. CONCLUSION: The regular changes of the levels of sCD23 may lead to decreased immune function in MHD patients, which are associated with the membrane's biocompatibility. The reuse of the dialyzer may ameliorate membrane biocompatibility.

尿毒症维持性血透患者血透过程中血清sCD23水平规律性的变化，是导致患者机体免疫力下降的可能原因之一，而这些变化与透析膜的生物不相容性有关，HE和PS生物相容性优于CA，透析器复用可改善透析膜的生物相容性。

With the large-scale current of the construction project, as the requirement variety of the construction development impetus actor and the variety of the time and role when the contractors intervention of theproject, the paper brings forward a new pattern of integration management------PLMT mode,which aims at over process disseverment of the construction project、reducing the mutual dissension and conflict of every project actor, and makes the employer have abundant decision-making control right, as well as not to be immersed in idiographic project management.

随着建设工程项目大型化的趋势、作为建筑业发展动力的发包方的需求变化以及承包方介入项目时间和角色的变化，本文提出一种旨在克服建设工程项目过程之间的割裂、减少项目各参与方之间的相互争执和冲突，让发包方既有充分的决策控制权，又不陷于具体项目管理工作的新型集成管理模式——建设工程项目全寿命周期一体化管理模式。

Instead of seasonal, they are diurnal.

海陆风不是季节变化的，而是昼夜变化的。

The Utopia, I argue, is not a representation but an operation calculated to disclose the limits of our own imagination of the future, the lines beyond which we do not seem able to go in imagining changes in our own society and world (except in the direction of dystopia and catastrophe).

我认为，乌托邦不是一种表征而是一种作用，旨在揭示我们对未来想象的局限，超越这种局限，我们似乎再不能想象我们自己社会和世界的变化（除非是反乌托邦和灾难方面的变化）。

The reasons for these complications: The main arteries as a result of high blood pressure resulted in a series of changes, especially the long-term systemic small artery spasm, may cause the vessel wall occurred in dystrophic changes in subintimal deposition of protein substances, fibrous tissue increased , in the muscle membrane hypertrophy, reduced arterial elasticity, resulting in luminal narrowing.

产生这些并发症的原因：主要是由于高血压使动脉产生了一系列变化，尤其是全身小动脉的长期痉挛，可能使血管壁发生营养不良性变化，内膜下蛋白性物质沉积，纤维组织增多，中膜肌层肥厚，动脉弹性减低，以致管腔变窄。

From 24h to 96h, the removal rates of NH4 -N in every experimental group were all negative indicated that when being exposure to Hg2 , Egeria najas not only couldnt remove NH4 -N from water, but also would increase its concentration.

在24-96h的处理时间内，各实验组中细叶蜈蚣草对NH_4~-N的去除率基本为负数，说明在Hg~(2 )的作用下，细叶蜈蚣草不仅不能去处水中的NH_4~-N，相反还可能使水中的NH_4~-N增加。96h内水体NO_3~--N含量变化无明显的规律性，而细叶蜈蚣草对水体NO_3~--N的去除率变化规律比较一致，先上升后下降最后比较平稳。

In this problem, the main difficulty is that the variation of border electric potential is not sensitive to the variation of conductivity in the field. So far, there is not an effective method to solve the problem.

在低频电流场逆问题的计算中，最大的问题在于边界电位值的变化对场域内部电导率的变化不敏感，到目前为此，对此问题还没有一个公认的有效的解决办法。

At the latter consolidation stage, it was assumed that the water flow only depended on water pressure and was not influenced by the air. Then the independent continuity equation of water was set up to solve variation of water pressure with time. Besides, the water and air were regarded as mixed fluid, and the continuity equation of mixed fluid was set up.

在其后的固结过程中，假定水的流出仅仅取决于水压力，不受气的影响，单独建立水的连续性方程，解水压力随时间的变化；又将水和气看成混合的可压缩流体，建立混合流体的连续性，解混合流体压力随时间的变化。

In Chapter 3, we obtain the Equilibrium Principle of the Rate Return in Financial Market, that is, the weighted sum of instant rate of return of nodes in the network is a constant.

本文第六章研究了出现突发事件时的收益率—流通量方程，证明了不同时间段的网络平均收益率也不相同，并且随脉冲条件的变化而变化，同时给出了相邻两个时间段网络平均收益率之间的关系。

Choose the one that is the most equivalent to the original in terms of meaning and expression.

然而现代的人却使尼罗河发生了变化，不过就连他们自己也不完全了解尼罗河究竟发生了什么变化。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
