查询词典 lead time

The restoration of dentition meant not only to fill the missing teeth and increase the efficiency of mastication, but also to maintain the integrity of dentition and the health of residual teeth, especially loosen teeth that could be reserved. Bone resorption might lead to teeth mobility and the change of occlusal pattern and proximal relationship. Also, the endurant threshold to bite force decreased. Occlusal loads within the normal range to loosen teeth would lead to broken down of periodontal tissues.

中文题名PVDF咀嚼力测试仪的研制及松动牙咀嚼生理功能的研究副题名外文题名 The study of masticatory performance of loosen teeth and PVDF-based instrument for dynamic chewing force measurement 论文作者李鸿波导师姚月玲教授学科专业口腔临床医学口腔科学研究领域\研究方向学位级别博士学位授予单位第四军医大学学位授予日期2002 论文页码总数108页关键词牙列缺损松动牙咀嚼力最大〓力馆藏号BSLW /2003 /R783 /9 修复牙列缺损不但要修复缺牙、恢复咀嚼功能，也要维护牙列的完整性、保护余留牙，尤其是可保留的松动牙的健康。

So consequencetly difference in age structure of Engraulis japonicus populations would lead to change its element compositions. Since Engraulis japonicus was one of the most important diet to high trophic fishes such as Scomberomorus niphonius and Trichiurus lepturus, Unbalance of supplying elements of potential diets would directly lead to the facts that some fish species would grow slower and smaller.

因此，鳀鱼种群年龄结构的变化导致了种群元素组成的变化，同时由于鳀鱼是上层鱼类的重要饵料，因此潜在饵料的元素供给失衡，直接导致带鱼等鱼类因鳀鱼资源衰退而生长缓慢，个体瘦小。

Neither team took a lead larger than seven points in the first three quarters, with the Bobcats constantly staying close to the Lakers on big baskets from Stephen Jackson. Nazr Mohammed's fallaway jumper with 1:38 to play trimmed Los Angeles' lead to 93-92, but Pau Gasol responded with a quick hook shot before blocking Jackson's driving layup.

在前三节没有一支球队的领先分数能超过7分，夏洛特山猫凭借斯蒂芬-杰克逊超能力的表现一直紧咬着比分，默罕默德在比赛还剩下1：38的时候后仰跳投命中帮助山猫将比分追至92-93，但是随后保罗-加索尔一记转身勾手命中，回来又封盖了杰克逊的上篮，让湖人继续保持领先。

It was indicated by SEM spectra of ZnO thin films that the surface of the sample was leveled off, and the crystals were felsitic. It was found from the experiment that, with the increasing of substrate temperature, there were more oxygen vacancies in the films, which lead the conductance of the sample become larger , and the absorb edge of ZnO thin films shifted toward higher wavelength; with increasing of Ar:O2 ratio, there were lesser oxygen vacancies in the films, which lead the absorb edge of ZnO thin films shifted toward lower wavelength.

实验还发现，随着衬底温度的升高，薄膜中产生的氧空位将会增多，使得ZnO薄膜的电导逐渐增大，而且其紫外透射吸收截止边带向高波长方向漂移；随着氩氧比例的增加，薄膜中的氧缺陷相对减少，薄膜的透射吸收截止边向低波长方向漂移。
