引起因素

Analysis of the archives data of Hetian region during the Republic of China showed that this time water resources basically maintained on a stable level, and it was not the decisive factor to the waste of local big area tilth, but the essential factor actually restricted the population quantity, the reclamation wasteland scale and the overall cultivated area level in all the counties.

地区人口增长过多引发对地区耕地面积的需求扩大，同时引起对耕地灌溉水量的增长需求扩大，由此呈现出农田灌溉水不足的表象，造成地区人口、耕地水平与水资源承载力相互关系的失调；即影响和田地区耕地撂荒的关键是当地水资源总量与人口规模、耕地面积总水平的平衡关系，突破这个平衡就必然引起耕地的撂荒或生态环境劣化；而诱发耕地大面积撂荒的自然因素也与过度垦荒有一定程度的关系。

The Mo-coating is only effective in improving TRS in cobalt-based matrix, the reason of which was also discussed inthe paper.

抗弯强度的变化主要是由于Mo对结合剂的局部强化、硬化并由此引起的复合材料内部的热应力的改变以及Mo层改变了结合剂对金刚石的浸润等因素引起的。

The decrease of brain blood flow is one of the pathological factors that cause VD.

脑血流量下降是引起血管性痴呆的重要病理因素之一，与学习记忆相关的脑区供血不足可以引起学习记忆障碍等痴呆症状的出现。

In the third stage, the column-shaped ice crystals grew mainly in its length and the ice crystals had the acerose shape gradually, and the growth rate of frost thickness increased rapidly to 3-5.8 times that in the second stage. It is found that the performance degradation of the ASHP unit was caused by the wall temperature drop of the evaporator, the rapid increase in the frost thickness, and the decrease in the air flow rate.18Refs.

对实验结果的分析表明，热泵机组性能恶化主要是由于蒸发器表面温度下降、霜晶形态变化引起霜层厚度快速增长及空气流动阻力增加导致风机流量下降三个因素之间形成的恶性循环所致，其中换热器表面温度下降引起的霜晶形态变化起到了至关重要的作用。

Bhat and his team of MUSC Neuroscientists tested their hypothesis that high cholesterol, resulting from either diet or genetic disposition, would intensify the brain's inflammatory response and spur amyloid generation that would, in turn, lead to the neurodegeneration and dementia characteristic of Alzheimer's disease.

他们的研究工作验证了这一假设：即不管是饮食引起的或者遗传因素造成的高胆固醇都会加剧大脑的炎症反应，并刺激淀粉样蛋白的产生，逐步引起神经退行性病变并出现阿尔茨海默病的痴呆特征。

Among all the factors leading to genetic instability,centrosome and telomer...

在众多可能引起基因组不稳定的相关因素中，中心体和端粒酶所起的作用较为重要，且已引起越来越广泛的关注。

Many cases of preterm PROM are caused by idiopathic weakening of the membranes, many of which are caused by subclinical infection. Other causes of PROM include hydramnios, incompetent cervix, abruptio placentae, and amniocentesis.

许多足月前胎膜早破的发生是由于亚临床感染造成羊膜特发性改变引起的，其它引起胎膜早破的因素还包括羊水过多，宫颈内口松弛和羊膜腔穿刺术。

The infectious agent responsible here was Nocardia, which is known to produce chronic abscessing inflammation.

此处引起感染的因素是诺卡菌属，主要引起慢性脓肿。

Our studies indicate that the increased contents of glucose and accumulation of active metabolic intermediates due to metaboic disorder contribute to the cutaneous environmental alterations associated with diabetes mellitus.Thus,the cutaneous environmental alteration is one of the initial events for impaired healing.The succession of progressive injury in deep partial thickness burn wounds is carried out depending on the physiological outcome of parabiotic tissues.The loss of dernal template due to the damage to the integrity and the continuity of dermal tissue may be one of the leading reasons of hyperplastic scar formation.

通过对糖尿病合并创面难愈、烧伤创面的进行性损害以及增生性瘢痕形成的机制研究，我们发现：糖尿病代谢紊乱所致皮肤组织中糖含量增高和代谢产物蓄积引起的皮肤微环境改变，是导致糖尿病创面难愈的始动因素之一；烧伤后的组织进行性损害的发生发展取决于&间生态&组织的病理转归；真皮组织缺损导致的模板作用缺失可能是引起增生性瘢痕形成的始动环节。

In 1956 Gilbert Plass was heir to a century of work that identified variations in the trace amounts of carbon dioxide in the atmosphere as a possible cause of ice ages and interglacial periods.

1956年的吉尔伯特·普拉斯深受一个世纪以来科学工作的影响，当时认为大气中微量二氧化碳的变化是引起冰川期和间冰期的因素之一。1861年约翰·丁达尔写道，大气中任何有放射活性的物质（水蒸气、二氧化碳、臭氧或烃类）数量发生微小的变化，都可能引起&地质研究所发现的各种气候变化……它们是真正的原因，只是有多大范围的影响还存在疑问。&
