查询词典 lead-free

It shows in clinic as tooth sensitivity, pulpitis,periodontitis,food impaction ,deformation of basifacial caused of loss of occlusal height, temporomandibular disorder syndrome, etc. The wear property of artificial tooth material will lead a direct effect to restoration result, when it exists in oral environment. It will cause tooth enamel loss too much in a very short period, if the wear property of artificial tooth superior to tooth enamel; but if it is inferior to tooth enamel, serious wear will occur on restoration occlusions, which will lead to loss of bite functions and even decrease of occlusal vertical dimension, disorder of bite functions, etc. Therefore, it is important to artificialtooth material not only it"s biotic compatibility, mechanical function, chemistry property but also it"s wear property.

当口腔中存在修复体时，人工牙材料的磨耗性能也直接影响临床修复的效果，当其磨耗性能强于天然牙釉质门时，将会引起天然牙釉质过度磨耗；当其磨耗性低于天然牙釉质时，又会在较短时期内引起修复体咬合面磨损过度，失去咬合功能，严重者甚至出现咬合垂直距离降低，咬合功能紊乱等症状因此，对于人工牙材料除了考虑生物相容性、机械性能及化学性能外，还应考虑到材料的磨耗性能，而磨耗率的测定一直是评价天然牙及人工牙磨耗性能的优越指标之一。

Among these results, we suggested that the monomer structure play a important role between E-O performances and morphology. Monomer STD02 shows fastest response time, and monomer M3 exhibits slowest one. As a result for roughness, it's the same with response time. From SEM photograph, the beadlike morphology was obtained from monomers without spacers. On the other hand, the filberlike morphology was obtained from monomers with spacers. It's suggested that the more harder structure will lead to the former, and the more softer structure will lead to the latter.

发现 STD02 反应时间最快，而 M3 则是最慢，而粗糙度大小也是与反应时间相符合，最大的是 STD02 而最小的是 M3，在 SEM 下结果显示，各单体所呈现的型态皆为颗粒状且排列均匀，因无含烷链段关系导致形成的型态为颗粒状，论文里有提到另一种单体含烷链段其所形成的型态为纤维状，以结构上来看，越是刚硬之单体所形成的型态都较易为水滴或是米粒状，而结构上越是柔软，所形成的型态都较易为稻穗或是纤维状。

The pyrimidine lead compound is obtained via herbicidal activity screen. The optimization of lead compound leads to find the good pyrimidine benzylamine candidates with highly effective herbicidal activity. The novel herbicidal mechanism of pyrimidine benzylamine is put forward. N-(2-bromophenyl)-2-(4, 6-dimethoxypyrimidin-2-yloxy)benzylamine (103-1) has potential as a new selective post-emergent herbicide in oilseed rape.

通过系统的研究工作，发现了具有除草活性的嘧啶先导结构，经结构优化，筛选出具有高除草活性的嘧啶苄胺类优选结构，发现并提出了此类化合物的除草作用新机理，最终经田间试验证实了N-(2-溴苯基)-2-(4，6-二甲氧基-2-嘧啶氧基)苄胺(103-1)可作为超高效油菜田除草剂进行工业性的研究与开发。

Clean energy economy will lead to higher consumption per capita than harmful energy economy when CER value is high enough and the cumulative net capacity is zero. On the contrary, clean energy economy will lead to lower consumption per capita than harmful energy economy when CER value is not high enough, which means it is not able to counterweigh the cost of ethanol, or when ethanol production efficiency is low enough.

3当CER价值足够高而净资本累积为零时，洁净能源体系会较污染性能源经济体系造成较高之人均消费；反之若CER价值不够高，亦即不足以弥补燃料酒精生产成本时，或者燃料酒精生产效率足够低，则可能获得较低的长期人均消费水准。
