可避免的

The initial range-of-motion exercises are performed to prevent adhesion formation; extension is allowed to 0°, but it is essential to avoid both hyperextension and flexion past 90°, which can place undue tension on the grafts.

最初的关节活动范围练习主要是为了防止粘连形成，伸展的范围可达0°，但必须避免过伸以及屈曲超过90°，否则可能会使移植的肌腱承受过度的张力。

The research indicated that the computer navigation systems can enhance the accurate placement of tunnels, regarding the anatomical and isometrical parameters, without impingement on the intercondylar notch, to achieve individual ideal implantation using three-dimensional visualization localisers.

研究表明，计算机辅助系统通过三维的可视化定位装置，提高了隧道定位的精确度；按照解剖和等距参数，避免了移植腱与股骨髁间窝切迹的撞击，实现了适合于患者个体化的前交叉韧带的准确定位植入。

Both masker and probe were ramped on and off to avoid spectral splatter.

心理物理测量在依据以下情况实行：（1）频率1000赫兹、反应时间20毫秒的探测音其声音位准高于静音临界15分贝(如15分贝的感觉层次)，（2）将反应时间300毫秒的遮蔽音，其位准调整到可听闻试验中75%的探测音(如探测音仍然在其"遮蔽门槛"内)，遮蔽音和探测音两者断断续续地跳动，以避免频谱散射。3。

The technical advantages of the method include:much simplified,time-saving calculation;massy and coplicated simulation of 3D electromagnetic field distribution can be avoided and the existing data of rotational coil design can be used.

该方法不仅可以避免复杂的三维电磁场计算和优化，而且还可以利用现有的旋转对称偏转线圈的计算结果，因此可节省大量的时间。

Because the optimal triangle fuzzy numbers and optimal fuzzy vector which were used to replace the maximum sets and the ideal solution may be got by observation, not need the complex comparison process of fuzzy triangle fuzzy numbers.

研究发现，本文提出的模糊灰色关联分析法以可通过观察而直接得到的最优三角模糊数和最优模糊向量分别代替了以往的模糊极大集和模糊理想解，避免了模糊数比较的复杂过程，提高了模糊综合评价的决策效率。

The closed-form expressions are derived so that all required differentiations are obtained in closed form and numerical differentiation can be avoided.

特别是对微带和缝隙混合结构的空域MoM分析，旋度算子的微分在谱域进行，并可以给出它们的解析表达式，其对应的空域格林函数可通过高阶的Sommerfeld恒等式获得，从而避免了数值微分。

1 For water out of hydraulic system: adopt blocking and draining methods, unique draining structure is designed at the guide sleeve of the piston rod in pumping oil cylinder, which makes the water leaked into the scraper seal converging in the waterspout and drained through the osculum, thus avoiding the water getting into hydraulic system through the seal.

对于液压系统外水分：采取堵，排共施的策略，在泵送油缸活塞杆导向套处 2009 年第 1 版( The first edition in 2009) 18 HBT60.13.90S HBT60.13.90SC 设计有独特的排水结构，其可将渗入防尘圈的水汇聚于排水槽内并通过排水孔排出，从而避免了水分通过后面的密封进入液压系统，做到将水分拒之于系统之外。

Then the types of upper sensors are determined. The CMOS chip AT89C2051 is used in this system because there is only a small quantity of program to be stored. This system uses wireless transmission module D21DL to form the network of wireless transmission. In this way, such disadvantages as low removability and expansibility and longtime construction are avoided. Digital filtering method is applied to improve anti-jamming performance.

由于程序存储量较少，现场的CPU选用ATMEL公司的低档型芯片AT89C2051；为了避免采用有线数据传输导致的系统可移动性差、系统扩充性能差和系统布置线缆繁琐、施工周期长等缺点，本系统采用了无线数据传输模块D21DL构成系统无线网络传输；同时设计了包括电源电路、显示电路、存储电路和报警电路等构成系统的所有电路。

We believe in 'even distribution trumps poverty' by our tradition, but in such a system where interests and misfortunes are allocated evenly and 'sweetness and bitterness' shared according to convention, is there any sense of responsibility to be willing to keep self-restrained for 'others' being away from misfortunes?

日积累月的民众生活卫生习惯中，沉淀下多少恶习陋性——随地吐痰、随地大小便、随地抛弃果皮塑料袋、就餐分餐制难以推行、酒后驾车、公共场所吸烟等等……"我们"的传统文化是"不患寡，患不均"——在这利益与灾祸均享均沾、"同甘共苦"的行为惯性中，可有愿为"他人"避免灾祸而自控自律的一份责任感？

Thus Session XIII begins:"The Holy Synod forbids to all the faithful in future to believe, teach, or preach concerning the Holy Eucharist otherwise than is explained and defined in the present decree", and it ends: As, however, it is not enough to speak the truth without discovering and refuting error, it has pleased the Holy Synod to subjoin the following canons, so that all, now knowing the Catholic doctrine, may also understand what heresies they have to beware against and avoid.

"因此，第十三届会议开始："罗马教廷的主教禁止所有的忠实在未来相信，教导，或鼓吹关于罗马教廷圣体圣事，否则比是解释和界定，在目前法令"，它结束："不过，这是不足够的讲真话，没有发现和反驳错误，它高兴圣主教，以subjoin以下的大炮，以便使所有，现在知道天主教教义，也可明白什么歪理邪说，他们必须提防反对和避免。
