Every little while some giant tree yielded the fight and fell crashing through the younger growth ; and the unflagging thunderpeals came now in ear - splitting explosive bursts , keen and sharp , and unspeakably appalling 每隔一会，就有一棵大树不敌狂风，哗啦一声扑倒在小树丛中惊雷如潮，震耳欲聋，惊魂夺魄，难以言状。
Graduated from huaxi medicine university , engaged in ear , nose and throat clinic for 30 years , published over 20 thesis on china s medicine magazines , chiefly compiled series books on china and western medicine therapy 1963年毕业于华西医科大学，从事耳鼻咽喉临床工作30年，在中华医学杂志上发表论文20多篇，主编中西医诊疗丛书
The total automobile capacity throughout the world is 30 % more than the global demand . the situation i s expected to further intensify in ear i y 21st century due to the impact of the global economy and the needs of the automotive industry for readjustments 由于全球经济的影响和汽车工业本身调整的需要，预计在21世纪初这种状况还会进一步加剧，国际汽车工业的不景气，迫使各国汽车企业加快新产品开发，以观念创新、技术创新和营销创新开拓新的市场空间，竞争日益加剧。
Teresa was lively and gay , but coquettish to excess . the two piastres that luigi received every month from the count of san - felice s steward , and the price of all the little carvings in wood he sold at rome , were expended in ear - rings , necklaces , and gold hairpins . so that , thanks to her friend s generosity , teresa was the most beautiful and the best - attired peasant near rome 罗吉每月从圣德里斯伯爵的管家那儿得来的两个毕阿士特和他的木刻小玩意儿在罗马卖得的钱，都花在买耳环呀，项链呀和金发夹呀等等东西上去了，正是靠了她朋友的慷慨，德丽莎才成了罗马附近最美丽和打扮得最漂亮的农家女。
When inadequate n was added , the chloroplast structure in mesophyll cell was damaged in ear leaf , the amount of carbohydrate decreased in mestome sheath , and excessive n - redistribution and n - transportation to grain from vegetative mass appeared , which resulted in earlier leaf senescence . excessive n application led to too high activity of nitrate reductase , excessive vigorous nitrogen metabolism and too much exhaustion of carbohydrate in ear leaf , which resulted in the lack of enough carbohydrate in the lower leaf , meanwhile , the expansive chloroplast grana lamellae in leaf mesophyll cell and starch grain without nuclear in mestome sheath cell was observed , which led to the decrease of chlorophyll content and photosythetic capacity in maize leaf , then the early senescence occured 氮肥用量不足导致穗叶叶肉细胞叶绿体结构性差，维管束鞘细胞碳水化合物累积减少,营养体氮素再分配率大而引起叶片早衰；而过量供氮则导致生长后期硝酸还原酶活性过高，氮素代谢过旺，消耗了大量碳水化合物，以致下位叶不能得到充足的碳水化合物供应而提早脱落，同时叶肉细胞叶绿体片层结构膨胀，呈“肉汁化”特征，维管束鞘细胞淀粉粒大量消耗，无核淀粉粒出现，从而叶片叶绿素含量下降，光合能力降低而出现早衰。
