This article analyzed the method of calcify reaction on oxalic acid process and put forward the conditions of calcify reaction and acidify reaction.

根据钙化法草酸生产工艺的研究，提出了钙化反应、酸化反应的工艺条

Most subjects (89%) with no calcifications remained without calcification.

大多数无钙化的患者（89％）依然无钙化。

The larger the lesion, the more likely that it will calcify. Definite calcification is seen on plain film in up to 15%.

病灶越大，越容易发生钙化。15%的患者在胸片上可见明显钙化。

Chronic fungal infections frequently calcify, but bacterial and pneumocystic infections are not usually associated with calcification.

慢性真菌感染也常常有钙化，但是细菌性和肺囊虫感染却一般不伴有钙化。

CT is useful in evaluating the calcified matrix so characteristic of this lesion. This is reported to be seen in about 70% of cases.

CT在显示特征性的钙化上很有用，据报道有70％的病例会出现钙化。

The percutaneous balloon mitral valvuloplasty was performed in the patient with single thickened tendinous cordae.The valvular closed commissurotomy was performed in the patient with thickened non-calcified tendinous cordae.The ATC stereoscopic images that revealed by dynamic 3-D reconstruction technique could be not acquired in two-dimensional image technique.

结果：本组瓣膜病患者，有两组腱索增粗并钙化者及腱索稀疏与断裂者均行瓣膜置换术，仅单组腱索增粗者行瓣膜球囊扩张术，两组腱索增粗而无钙化者行瓣膜闭式分离术，动态三维重建技术展示了二维显像所不能获得的房室瓣腱索的立体图像。

This study of programmed cell death on coralline algae wishes to produce useful information for the protection of marine calcifying organisms.

这项钙化藻的程序性细胞死亡的研究目标提供保护钙化生物的有用资讯。

METHODS:Calcification of cultured rat VSMCs was produced by incubation with β-glycerophosphate. Calcium content, Ca2+ deposition and alkaline phosphatase activity were analyzed to estimate the extent of calcification.

目的：在离体钙化的血管平滑肌细胞上，观察内皮素受体阻断剂对血管平滑肌细胞钙化的影响，探讨内皮素促进细胞钙化的信号转导和分子机制。

Thyroid carcinomas have the characteristic CT findings: fine granular microcalcifications, cystic formation with intracystic obvious enhanced papillarylike nodules, peninsular tubercles around the tumour and no complete ring around the tumour.

颈部出现淋巴结转移40例（63.5％），其中增强后明显强化22例，密度接近于正常甲状腺组织，10例转移淋巴结有囊性变伴囊壁明显强化的乳头状结节，7例淋巴结最大短径。8 cm，7例乳头状癌的颈部转移淋巴结内有颗粒样钙化(5例为细颗粒状钙化，2例为混合性钙化)。

Results: Forty- four nodules were available for final evaluation. Average nodule volume was 501.9 mm3(range,17mm3～2496.4mm3).Thirty-two nodules had well-defined edges, and 12 had irregular or spiculated margins.

结果： 44个结节作为最终体积测量对象，肺小结节体积变化范围17 mm3～2496.4 mm3 ，平均值为501.9 mm3.32个结节边缘光滑，12个边缘不规则或呈针尖状。31个结节位于肺实质内，9个靠近胸膜，4个邻近血管。41个呈实性未见钙化，2个斑点状钙化，1个完全钙化。
