贝壳

The trial was designed by orthogonal L9 (3^4) of N, P, K nutrients and three levels respectively in this study. The effects of these nutrients and their levels on growth of seedling height and ground diameter of Agathis dammara were studied and the best fertilization method was determined. The results showed that the effects of high significant differences among different fertilization treatments through 1-8 months.

采用正交试验设计L9(3^4)，通过植物生长所需要的大量营养元素N、P、K三因素三水平及其不同配比的施肥试验，分析了各元素及其水平对贝壳杉苗高和地径生长的影响，确定了贝壳杉苗期生长的最佳施肥方案。

The meshwork results are obtained from the later pictures. They clearly show the structure of four-dimension reseau and some meshwork results of shell data. The reason why the whole results are not achieved is that there are too many circumstances in which five or more dots share the same orb. In this case, the principle Delaunay is not in point any more, then the process of establishing meshwork will be intermitted.

后面的4幅图是后来所作的工作，得到了1个正方体4顶点以及其中心点的建网结果，从这里能清楚地看到4面体网格的结构，还有对贝壳数据点云的部分建网结果，之所以没有完成整个贝壳数据的建网是因为数据中存在较多的5点或5点以上共球的情况，这种情况下Delaunay准则不再适用，建网会中断，所以只完成了1个部分。

The experiments show that one portion of amino organic compounds in the shell is changed to the volatilizable amine and the other portion is transformed to the involatile nitrate after pyrogenation.The organic compounds disappear completely at 600℃.They also show that the aragonite phase of calcium carbonate in pearl shell chang with temperature;the aragonite phase transforms to calcite at 500℃, but some of organic compounds is still residual;and calcium carbonate begins to decompose to calcium oxide at 600℃.

实验发现，贝壳中的氨基酸类有机物热降解后部分以胺的形式挥发出来，另一部分则转化为不可挥发的硝酸盐的形式，600℃有机物完全消失；同时，贝壳碳酸钙的文石晶相随温度而变化，500℃时转变为方解石结构，其中仍有部分有机物残留，600℃开始分解为氧化钙。

The microstructure of a mactra sulcataria shell was observed by scanning electronic microscope.

使用扫描电镜观察蛤蜊贝壳的微结构，结果显示蛤蜊贝壳是一种由无机文石和有机胶原蛋白组成的层状生物陶瓷复合材料。

The effects of silicane coupling agent on the properties of epoxy matrix composites filled with rigid shell powder were studied.

以贝壳微粉为刚性填料，研究了硅烷偶联剂对贝壳微粉改性环氧树脂复合材料性能的影响。

The deceased also wore a pendant made from the shell of a Spondylus, or spiny oyster—"a highly appreciated shell among the high-class during pre-Hispanic times for its orange-purple color," Gallaga said..

死者也佩戴着有海菊蛤贝壳的垂饰，或者长满刺的牡蛎。——&从其橙紫颜色可以看出，那是前西班牙时代上层社会中享有高度赞誉的贝壳。&

Among them the giant shell of tridacna of more than 1500 kg in weight is the weightiest shell so far found in China. The mini-shell of only 0.3 mm in diameter is the smallest one in north China. The most treasured is the spiral shell which was sold to Japan by Taiwan for 0.4 million Taiwan Yuan in 1970. It set the world record for its selling price.

其中有重达1500多公斤、全国迄今为止发现的最重的巨型砗磲贝；也有直径只有0.3毫米的我国北方最小的微型贝壳；还有1970年台湾以40万台币卖给日本、创下贝壳售价世界纪录的黄金宝螺。

Colour comparison were made by using a " shell colouration index ", which indicated the darkness of shells

分析时，用贝壳颜色指数来表示贝壳颜色深浅度特征。

Of,relating to,or being a surface characterized by smooth,shell - like convexities and concavities,as on fracture d obsidian.
