First, from room temperature to 500oC, the shell structure is amorphous with crinkly and airtight character. The shell structure begins to change into γ-Al2O3 and α-Al2O3 at 900oC. The surface of shells shows nano-sized pores at 900oC from SEM and BET analyses. When heated to 1000oC and 1100oC, the shell forms stable α-Al2O3 structure with smooth surface. Cracks often occur at the triple grain junctions. The specific surface area and the total pore volume of the hollow spheres increase with the calcination temperature.

首先，将锻烧温度由室温提升至500℃时，球壳属非晶相皱褶状致密结构；在900℃时开始有γ-Al2O3相及些许的α-Al2O3相出现，由SEM及BET结果得知，900℃之球壳表面有许多奈米级孔洞出现；当加热至1000℃和1100℃时，球壳形成稳定相之Al2O3结构，壳层表面趋於平滑，且球壳在晶界处有微裂缝存在；由BET 结果得知，比表面积及总孔洞体积会随锻烧温度之增加，有增加之趋势。

Due to the effect of curvature of shell, the equation of motion of elastic waves in shell is much more complex than that in plate. The method of operator factorization can't be directly used to solve the equation of motion of elastic waves in shell by reducing it to the second order partial differential equations.

由于壳体曲率的影响，使得壳体的弹性波动方程比平板的运动方程复杂得多，难以直接采用算子因式分解方法，将其化成二阶偏微分方程求解。

One thousand six hundred and fifty-six Hyline laying hens at 150 days of age were fed a corn-soybean-miscellaneous meal diet supplemented with 0, 0.1%, 0.2% and 0.3% of YC. Egg production rate, average egg weight, average daily feed intake, rate of death and cull, ratio of feed to egg, and egg Haugh unit, shell thickness, shell weight, shell strength and yolk color were measured. The trial lasted for 20 weeks.

There were significantly correlation among the 9 egg quality traits in silkies. There were positive phenotypic correlation among albumen proportion and egg weight (P.01), Haugh Unit and albumen proportion (P.05), shell proportion, shell strength and shell thickness (P.01) respectively. There were negative phenotyp

4本研究还进行了丝羽乌骨鸡蛋品质各个性状间的相关分析，结果发现蛋壳强度与蛋壳厚度极显著正相关(P.01)；蛋黄比例与蛋重极显著负相关(P.01)：蛋壳比例与蛋壳强度、蛋壳厚度极显著正相关(P.01)；蛋白比例与蛋重极显著正相关(P.01)，与蛋黄比例、蛋壳比例极显著负相关(P.01)；哈氏单位与蛋黄比例极显著负相关(P.01)，与蛋白比例显著正相关P 。

Egg quality traits of 901 hens from a pureline of dwaf layers were measured at the age of 40 weeks, including egg weight, Haugh Unit, shell strength, shell color, shell thickness, egg shape index and yolk color.

结果表明：矮小型蛋鸡40周龄蛋品质性状蛋重、哈氏单位、蛋壳强度、蛋壳颜色、蛋壳厚度、蛋形指数和蛋黄颜色的测定结果分别为：53.80g、86.40、3.3 kg／cm~2、41.78、342.90 μm、1.40、6.8。

Therefore,the pyrolysis temperature of shell having calcium carbonate is very high but the shell inappositely act as the stabilizer of polymer. This is instructing meaning to study additive and assistant of shell in the future.

因此，具有碳酸钙成分的贝壳虽然本身的热分解温度很高，但并不适合作为聚合物的热稳定剂，这对今后研究贝壳类添加剂或助剂有指导意义。

DLL To Display Shell Objects in a List V - This .dll encapsulates the shell automation library and displays shell objects (e.g., file/folder listings, as well as special folders such as the control panel and desktop) in a listview control.

In addition, micromotion between the nonarticulating side of the liner and the interior of the shell may be a source of polyethylene debris generation, or "backside wear." Recognition of this problem has led to improements in the fixation of the liner within the metal shell, and some designs also hae included polishing the interior of the shell.

另外，内衬的非关节面与金属帽内面之间的微动也可能是聚乙烯颗粒产生的一个原因，这称为"背侧磨损"，认识到这个问题，人们开始改进聚乙烯内衬与金属帽间的固定，而有些类型的假体金属帽内面是抛光的。

However, it is still difficult to find out the real reason of the increase of the keratinized gingiva during the orthodontic extrusion whether it is due to the proliferation of the gingival tissue or to its elastic nature, that is because the proliferation of the fibroblasts as well as the connective tissue changes in volume and the intra-fibers spaces were all immeasurable in most of the studies.

然而，仍然难以找到真正的原因增加的角化牙龈在正畸挤压它是否是由于扩散的牙龈组织或其弹性性质，这是因为增殖的成纤维细胞以及作为结缔组织的变化量和内部纤维空格都是不可估量的，大多数的研究。
