The pattern of diurnal cycle also can be classified into three strategies:(1) Planulation of S. hystrix and S. pistillata revealed a well-defined diurnal pattern with most planulae being released close to sunrise.

在日夜周期方面也可分成三种生殖策略：(1)尖枝列孔珊瑚与萼柱珊瑚有明显的日夜周期，释放幼生周期的同步性高，而且释放时间集中在天亮前后。

The pattern of lunar cycle can be classified into three strategies:(1) Planulation of S. hystrix and P. damicornis showed clear lunar periodicity and the peak of larval release shifted with different months. The peak of planulation occurred around the full moon in winter then shifted gradually to the first quarter moon phase in summer. The phase shift of larval release may be related to the seasonal variation of seawater temperature and the sudden temperature drops caused by upwelling.(2) Planulation of S. pistillata showed clear lunar periodicity and the peak of larval release occurred around the full moon.

在月周期方面可分成三种生殖策略：(1)尖枝列孔珊瑚与细枝鹿角珊瑚释放幼生不但有明显的月周期，而且释放幼生的高峰会随著月份而移动，由冬季至夏季期间，高峰从满月前后转变至上弦月前后；再由夏季至冬季期间，高峰从上弦月前后转变至满月前后，而此变动形成一个完整的年周期，原因可能与海水温度影响配子发育和胚胎速度与夏季期间涌升流所造成的降温有关。

Sleep-deprivation EEG was performed individually. Results The sleep deprivation EEG showed slow background electric activity in all 3 groups. In addition, the rates of EEG abnormality for nonepileptic seizures group were zero, no statistics were computed because F was a constant. Fifty-seven cases showed spindle/sharp-slow wave complex in suspected epileptic children.

结果 所有病例脑电图的背景电活动频率均明显变慢，非癫癎发作组38例睡眠EEG诱发试验均为阴性，因其诱发试验前后数据一致，故该组无统计意义；拟诊癫癎组脑电图有棘／尖慢复合波等癫癎样放电者57例(559%)；对照组诱发后脑电图异常出现2例(1.9%)癫癎样放电者，3组比较有非常显著差异(x^2=97.3 P0.01)。

Karyotypes of root tip chromosome showed that the arm volume ratio, the mean relative volume and idiogram were identical before and after improving seed vigor, so the pattern of chromosome did not change. But we couldnt confirm whether the pattern of other separation dates and the inner structure varied in this experiment, such as gene mutation.

根尖染色体核型分析结果，甘蓝种子在活力提高前后染色体的臂比值相同，相对长度相同，表明活力提高后染色体在形态及核型上无明显变化，而对于除中期外的其它分裂期染色体的形态特征以及染色体内部结构有无明显变异在本试验条件下尚不能确定。

objective to evaluate clinical effect of the handling protaper nickel-titanium rotary instruments in preparation of canals of posterior teeth.methods 96teeth with pulpitis or periapical periodontitis were instrumented by handling protaper rotary instruments using step-down technique,and by k files using step-back technique for control.all teeth were obturated with lateral condensation methods.the efficiency of preparation was analyzed with ra-diographs before and after operation.results no transportation,apical blockage and ledge were found in test.the technique could keep canals smooth.there were two ledge,one instrument fracture and nine transportation in control.the operative time was shorter and post treatment pain seldom occurred in handling protaper group.conclusion the handling protaper niti rotary instruments can prepare the canals effectively and safety.after the preparation,the canals could be easily washed,sterilized and filled.it is an efficient instrumentation method for posterior teeth's canals and be used widely.

目的 评价手用protaper预备后牙根管的临床效果。方法选取患有牙髓炎和根尖周炎的后牙96例，随机分成试验组和对照组各48例，试验组用手用protaper多锥度镍钛旋转器械逐步伸入法预备根管，对照组用k锉，逐步后退法预备根管，两组均用侧向加压充填法充填根管，根据治疗前后的x线片，评价后牙根管预备效果。结果试验组无根管偏移、根尖阻塞、台阶，且根管壁平滑流畅，无器械折断等并发症发生。对照组有2例台阶形成，器械折断1例，根管偏移9例。试验组操作时间短且术后疼痛轻微。结论应用手用protaper预备后牙根管快速、安全，成形效果好，易于根管冲洗消毒及填充，可视为临床上预备后牙根管的有效方法。

Also desirable seat, fingertip on the use of Baihui, two thumb-side, respectively, according to the rate of Valley Point (耳尖straight Division II cross-refers to), his hands at the same time for pre-and post-揉动, forced to be uniform, not too strong or too weak, There Pinggan Qianyang role.

也可取坐位，用中指端放在百会穴，两拇指端分别按在率谷穴，双手同时作前后的揉动，用力要均匀，不宜过强或过弱，有平肝潜阳的作用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
