Sleep problems beyond these ages take many forms , including difficulty falling asleep at night , frequent nighttime awakening , atypical daytime napping , and dependence on feeding or being held for sleep 大于这个年龄的睡眠问题各不相同，如，夜间难以入睡、夜间频繁醒来、昼间瞌睡无规律，喂着或抱着才能入睡等。
Candidates for stellar - mass black holes were identified mainly by the presence of accretion disks of the right size and speed , without the irregular flare - ups that are expected from disks around other compact objects 鉴别恒星质量黑洞主要靠合适大小和速度的增大圆盘的存在，没有认为从其它紧密物体周围闪耀的无规律的闪光。
3 ) individual development of fracture is of its internal origin and law ; while multi - developed fractures often occur in coincidence , forming existing non - order fractural system which results in complexity of appraisal of fractures 单个期次的裂缝发育有其内在成因和规律，数个期次有规律的裂缝叠合，形成“无规律”的现存裂缝系统，从而使裂缝评价复杂化； 4
Is a 3411 case of gb color television sets , in just two years from damage to the six previous damage erratic , but for a couple of days ago after a fault has now emerged , i do not know what reasons , you who aircraft repeated loss transformation decoder board 现遇一台3411gb彩电，在短短两年内损坏了六次，前几次损坏无规律，但前两天换了一块后现在故障有出现了，不知是何原因，各位谁有该机屡损解码板的技改方案？
However , we should not neglect a detail that the images have been placed along the timeline in a disorderly and unsystematic way : from the egyptian pyramid to the head of george washington , various images of people and events of all ages are put together in pell - mell ( at least seemingly so ) 但同样不应当忽视的一个细节是，时间轴中的影像是零散无规律的，古埃及的金字塔、华盛顿的头像、古往今来各种各样的人和事被混乱（至少貌似混乱）地摆放在一起。
Making up nanopaint mixed with nano - silica , the improvement of its properties has been tested . the mechanic property of membrane formed increased , such as tensile strength , elongation at break , surface rigidity ; the scrubbing resistance and stain resistance of the paints has been improved . but it ' s the limitation that ideal results of properties of waterproofing and uv - screen have n ' t been gotten 实验结果表明，涂膜的力学性能得到提高，如拉伸强度、断裂延伸率和表面硬度；涂料的耐洗刷性能和耐沾污性能有改善，但防水性能和抗紫外性能无明显改善，接触角和吸水率数据无规律可循。
Compared with pccr , the style of handwritten chinese character is diverse and optional which is hard to find rules in it . furthermore recognition of similar character in off - line hccr is much more difficult than that in pccr because of the ubiquity of handwritten distortion 与印刷体汉字识别相比,脱机手写体汉字识别具有书写风格众多、随意性较大、几乎无规律可循、复杂汉字难以识别等特点,并且由于手写变形的问题普遍存在,所以手写体汉字中相似字的区分比印刷体要困难得多。
Associating with the research and development of national natural heavy concentrate system , considering the feature of natural heavy concentrate database separately stored in every province , which is of mass data , discrete , irregular distribution , and influenced by hardware factors , such as computer configuration and network transfer speed , distributive database and parallel computing philosophy is applied , zone partition and multi - threading queue method is employed to retrieve and process the discrete data within a certain polygonal zone 结合全国自然重砂系统研制,针对分散存放在全国各省的自然重砂数据库,数据海量、离散、分布无规律、受计算机配置、网络速度等硬件因素影响的情况下,应用分布式数据库及并行运算理念,采用区域分片及多线程队列方法对某个多边形区域内的离散数据进行检索与处理。
The development of control system of wastewater disposal at home and abroad was introduced , and the practicability of fuzzy control system was demonstrated . aiming at the characteristic that dissolved oxygen changes irregularly in wastewater disposal . a suit of fuzzy control system whose control parameter is dissolved oxygen was designed 本文介绍了污水处理控制系统的国内外发展状况；论证了模糊控制系统的实用性；针对污水处理中溶解氧的变化无规律可循的特征，设计了一套以溶解氧浓度为控制对象的模糊控制系统。
