Seventhly, the effect of reuse of HY zeolite on isomerization reaction wasstudied.The results were as follows:when the HY zeolite was used many timescontinuously, the conversion rate of pinene dropped down markedly, but theselectivity of camphene fell no more.

7HY型沸石分子筛的重复使用对异构化反应的影响的结果指出，HY型沸石分子筛连续多次重复使用，蒎烯转化率显著降低，但莰烯选择性没有明显降低，其经烧炭再生能重复利用。

Based on the reason analysis of failure primary fracturing, the fracturing fluid and proppant of refracturing were optimized, the half-length of fracture and construction parameters were also optimized for the optimum design of refracturing wells.

同时对初次压裂失效的原因进行分析后，对气井重复压裂的压裂液、支撑剂进行优选，对重复压裂气井的裂缝半长和施工参数进行优化，从而完善对气井重复压裂的优化设计。

By utilizing the cross-gain modulation effect and the period-one oscillation harmonic frequency-locked in an optically injected semiconductor laser, we can extract the wavelength conversional individual channel optical clock from the optical-time-division-multiplexing signal. In a FP-LD, we numerically simulate the extraction of 20 GHz optical clock at 1550 nm from the 2×20 Gb/s OTDM signal at 1555 nm, and experimentally obtain the -105 dBc/Hz phase noise frequency division clock of 12.36 GHz to 6.18 GHz with simultaneous wavelength conversion from 1550.24 nm to 1545.91 nm.

Some examples are: The dual can also be rendered in a number of ways:· twofold repetition of the ideogram:· twofold repetition of the determinative sign:· a combination of the dual-suffix and repetition of the determinative sign: Vocabulary

一些例子：双还可以提供数种方式：·双重重复字：·双重重复决定性的迹象：·相结合的双后缀和重复决定性的迹象

To weaken the influences of the position-dependent periodic disturbances and parameter uncertainties, the robust repetitive controller was designed, which associated structure singular value theory with the discrete-time repetitive control theory. The problem of robust repetitive control was transformed into one of H∞ optimal control using linear fractional transformation. The robust repetitive controller was achieved using D-K iteration procedure and made the servo system have stability, robustness and tracking performance.

为了削弱周期性扰动及参数变化不确定性的影响，将重复控制和结构奇异值理论相结合，利用线性分式变换(linear fractional transformation，LFT)将鲁棒重复控制问题转换成H∞最优控制问题，采用D-K迭代法设计鲁棒重复控制器(robust repetitive controller，RRC)，实现系统的稳定性和鲁棒性，提高系统的跟踪特性。

Eighteen patients qualified for re-treatment at 6 months, 6 patients were re-treated at a later time point because of a disease relapse, and 2 other patients were not re-treated because they had low disease activity.

结果发现，在重复治疗的24例患者中，7例患者第1个疗程无效，后来重复使用利妥昔单抗仍无效；而剩下的在第一个疗程有效的17例患者中，第2个和第3个疗程的疗效与第一次相似，重复治疗前无明显复发。

And analytical comparison shows: The parameters of repetitional times and groups can be obtained through the experiments of intermittent trainings. Meanwhile, there are remarkable difference between the parameters which the individual can endure in same subsection-distance trainings and those in ...

研究表明：相同分段距离和不同分段距离具有个体所承受练习的重复次数与组数指标；个体所承受练习的重复次数与组数指标存在着差异性，个体所承受练习的重复次数与组数指标的获得，为运用间歇训练法，并产生最佳训练效果提供科学依据。

Do with same Ge program, have repeat, the person that can do pattern plate is very few, forum releases with respect to pattern plate of that a few Ge, you has repeat, if you go,the word of the resource of the library of other natural resources with imperscriptible perhaps library of resource of Cai government Marx is to repeat more then.

用同一个程序做，有重复，会做模板的人很少，论坛发布的就那几个模板，又有重复，如果你去采官方马克思资源库或者非官方的其他资源库的资源的话那更是重复了。

The complex was characterized by FT-IR, XRD, BET, SEM and EDS. The resin-supported catalyst exhibited high catalytic activity in the Heck reaction and could be reused up to 17 times in NMP or 16 times in DMF at 90 ℃ in the Heck reaction of iodobenzene with acrylic acid.

该负载型催化剂对Heck反应表现出高的催化活性和很好的重复使用性能，于90℃的碘苯与丙烯酸的Heck反应中，在NMP溶剂中能重复使用17次，在DMF溶剂中能重复使用16次。

The design and operation of the water reuse system when designing the reuse tank ,we think of the real regular pattern of waste water to do our best to well-distributed reuse and reduce the lash load.

水的设计和操作重复使用系统当设计重复使用箱的时候，我们觉得废水的真正一般的式样尽力到好的-分配了重复使用而且减少鞭子负荷。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
