经X线照相、软X线显微照相、荧光标记分析、脱钙组织学切片、不脱钙骨磨片以及计算机病理图象分析等6种方法，观察PCHA在宿主骨内的成骨规律、速度、和计量。

Pillared montmorillonite, as a representative of Sandwich like pillared interlayered clays ,caught many scientist"s attention not only because of its special structure of two-dimensional sheets but also its excellent activity of catalysis and adsorption. It is well documented that the method to prepare PILM, ion-exchanging, needed a long periods and was affected by many factors, and that the product had low thermal stability especially hydro-thermal stability which was the primary obstruction of its using in large-scale production. At the same time, PILM was well documented prepared with Na-montmorillonite, while there were a few documents about PILM prepared with Ca-montmorillonite. The large cost of remodel of Ca-montmorillonite to Na-montmorillonite was another obstacle of the application of PILM, while Ca-montmorillonite was widely distributed in nature, as a result, to prepare PILM with Ca-montmorillonite has practical significance. What"s more, PILM was mainly studied as a catalyst in oil refining process till now, but rarely documented in other catalysis reactions, especially in coal liquification filed which also needed high activity catalyst.

以柱撑蒙脱石为代表的具有&三明治&结构的柱撑粘土矿物因其特殊的二维孔道结构和优良的催化和吸附性能近年来成为国内外广泛关注和研究的热点，但是目前国内外大量报道的PILM制备大多采用离子交换法，生产周期很长，影响因素很多，并且产物热稳定性不够高，特别是水热稳定性较差，这是其不能在实际中大规模生产和应用的主要障碍，因此制备一种高稳定性的PILM意义非常；文献中大量报道的都是钠基蒙脱石合成的柱撑粘土矿物，传统的离子交换法必须将钙基蒙脱石钠化改型，其成本相当高，而自然界中大量存在的却是钙基蒙脱石，直接用钙基蒙脱石合成柱撑粘土矿物有很现实的意义，但目前这方面的报道却很少见；另外，迄今为止，PILM作为催化剂的研究领域主要在石油的炼制中应用，而在煤炭的液化中却鲜有报道，如果能在煤炭转化领域应用这一成果，其影响也将是相当大的。

The results also show that the mechanism of lead capture by CaO involves a chemical reaction between CaO and PbCl2, forming calcium plumbate (Ca2PbO4) as the dominant reaction product.

由於氧化钙被用来除去高温废气中之气态硫化物，因此，氧化钙对氯化铅(PbCl2)的高捕获效率显示其应可用来同时袪除氯化铅和硫化物。

However, when the amount of Bi dopant is large enough, a new pyrochlore phase of appears in the thin film.

当Bi掺杂量很大时，薄膜不再以单一钙钛矿相存在，而是得到了钙钛矿和焦绿石相共存的复相薄膜。

The results show that pyrochlore appears in the films when crystallization temperature is 400～600℃ and films with a large quantity of perovskite can be obtained using rapid heating process.

用不同升温速率控制PZT薄膜晶化过程，实验结果表明，当晶化温度在400～600℃时，薄膜显焦绿石相，当采用较高升温速率50℃／min时，在硅片上可缩小焦绿石相生成，提高钙钛矿相形成，从而获得取向性高的钙钛矿相PZT薄

Methods This study contained a total of 16 culture groups, including one group as control and 5 groups treated by 5 drugs (calcium L-threonate, sodium L-threonate, alendronate, 17β-estradiol and calcium gluconate) each at the final concentrations of 10^(-9)mol/L, 10^(-7)mol/L, 10^(-5)mo1/L respectively. After 7 days, eight bone slices of every group were stained with toluidine blue and the areas of resorptive pits were analyzed under light microscope; the concentrations of C-telopeptide of type Ⅰ collagen CT(subscript x or Crosslaps in culture supernatants were measured by ELISA.

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
