Local defects in bone as a result of trauma, neoplasm, infection, or congenital diseases are usually filled in and repaired with autografts The fresh autografts are considered to have the highest osteogenous capacity and no immune reaction.

外伤，肿瘤或感染施行骨切除或某些先天性疾病等原因引起的骨缺损常用自体骨填补，修复，其主要原因是自体新鲜骨成骨能力好，无免疫排斥反应。

Driven partly by the hope of outflanking the Islamic world, partly by the hope of trade, the Portuguess by 1446 reached Cape Verde, then the equator, and by 1482 the Congo River. In 1488 Bartholomew Diaz rounded the Cape of Good Hope at Africa's southern tip, and in 1498 Vasco da Gama went on to India.

探索的一部分原因是希望能将回教区域包围起来，另一部分原因是想在其它区域建立贸易渠道，因此到1446，葡萄牙人就已登陆了Verde角、赤道，到1482年，登陆了Congo河。1488年，Bartholomew Diaz到达了非洲南端的好望角。1498年，Vasco da Gama到达了印度。

These reasons resulted in the primary and junior high school lessons burden overweigh on, certainly this is not all, it various, multilayers of, so say that resolve this problem also is not at that time a moment and can complete of, we only recognize the pure reason, prescribe medicine for specific ailment, then can resolve by the root and thoroughly.

综上这些原因造成了中小学课业负担过重，当然这不是全部的，它是多方面，多层次的，所以说解决这一问题也不是一时一刻就能完成的，我们只有认清原因，对症下药，才能从根本上彻底解决。

By analyzing the dissimilated trend in women's self because of their catering for patriarchic views, the process of self-lost when they are gradually dissimilated into tools for traditional ethic is discovered, so did the reason of women's self-dissimilation and heterosexual hatred.

通过分析女性的自我因迎合传统女性伦理观而导致的物化倾向，展示了女性在逐步异化为传统伦理的工具性符号时自我的丧失过程，并从社会伦理层面上分析女性自我异化的原因，以及异性间憎恨关系的原因。

These phenomena might explain back pain on some patients after insertion of pectus bar and sporadically reported thoracic scoliosis after Nuss procedure. Moreover, we developed two thoracic volume measurement procedures to estimate the thoracic volume change of postoperative PE patients.

根据分析结果发现，患者於手术后，其背部靠近脊椎附近，有大量的应力产生，其中大多集中在第三到第七对肋骨上，这个现象可用来解释，某些漏斗胸病患，於纳氏手术后产生背痛之原因，并且可能与少部分患者，於手术后发生脊柱侧弯之原因有关。

RESULTS: Localised peripapillary detachments did not cause any symptoms by themselves and all the lesions were recognized because of other ocular problems.

结果：视盘周围视网膜脱离不是任何患者就诊检查的原因，视力减退或矫正视力低的原因是相对严重的近视性视网膜脉络膜萎缩、CNV、黄斑前膜形成和弱视。5只患眼表现为1型后巩膜葡萄肿，其视盘周围视网膜脱离均位于视盘的鼻侧半，而另5只患眼表现为3型或2型葡萄肿，其视盘周围视网膜脱离均位于视盘的非鼻侧半，统计学上存在差异（P=0.01）。

Cause pily grade to drop besides climate reason, advanced course cotton decreases apparently outside, cotton is current the disorder of system, put the negligence of pair of pily quality problems that be in generally, a few places are impure even make the person such as false become a common practice is a reason, also make quality of new this year cotton nots allow hopeful, cheated a shadow again to the pily resource that supplies insecurity originally.

除了气候原因造成棉花等级下降，高等级棉花明显减少外，棉花流通体制的混乱，普遍存在的对棉花质量问题的忽视，一些地方甚至掺杂使假成风等人为原因，也使今年新棉质量不容乐观，给本来就供应紧张的棉花资源又蒙上了一层阴影。

Combining the available regional geological and geophysical research, the petrogenesis of the magmatism was studied. As a response and absorption to the IndiaAsia collision, the northeastward flow of the asthenosphere beneath the Tibetan Plateau along the 400 km depth interface was blocked by the North China craton, and caused a systemic sequences in West Qinling Region, including the strikeslip fault systems and pullapart basins in the shallow crust and the origin of the twotype magmatism in this work in deep lithosphere. This explanation is consistent with the lithology and plumelike geochemical features of the kamafugite and potassic trachybasalt, which are significantly different from the potassic magmatism within the plateau and its adjacent regions.

结合前人对该区深部地球物理和断裂构造的研究，论证了火山岩的起源与成因，指出作为对印度-欧亚大陆强烈碰撞的吸收与调节，高原下软流圈地幔流沿400 km界面向北东方向的侧向流动以及西秦岭周边克拉通块体的阻挡，是形成西秦岭断裂系左行走滑特征和巨大拉分盆地的主要原因，也是导致西秦岭新生代两类钾质火山岩和碳酸岩起源与成因的动力学机制，较好地解释了西秦岭新生代岩浆作用起源深度大，具有地幔柱源的地球化学特征，岩石组合与地球化学有别于高原内部及其周边地区新生代钾质火山岩的原因。

The introduced techniques include changing the state of firebox in lamellar sample and the state of the sample in firebox, changing oxygen pressure in firebox and adjusting operation mode of rotating key which controls the electrical current of portfire.

该文分析了燃烧热测定实验常见的失败原因，并针对其中的主要原因，提出了 4点改进方法，即改变燃烧丝在片状药品中的状态和位置，改变药片在氧弹内坩埚中的状态，改变氧弹内氧气的压力值和改变点火电流控制转钮的操作方式。

Postmortem changes; a postmortem examination to determine cause of death; postmortal wounds.

死后的变化；确定死亡原因的尸体检查；死后的伤口。死亡原因不明。

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。
