部分硬化的

The part to be case hardened is immersed in a bath of fused sodium cyanide salts at a temperture slightly above the Ac range, the duration of soaking depending on the depth of the case.

将部分案件硬化是沉浸在洗澡的融合氰化钠盐，温度略高于交流范围，浸泡时间取决于深度案件。

Dr. Hooper notes that the work is part of the long-range goal of determining the exact role of blood-brain barrier permeability in disease.

Hooper博士指出：这个实验是确定血脑屏障通透性在多发性硬化病中确切作用的大范围实验的一个部分。

Results Of total 8 cases, 4 eases were located in the side of cerebral falx or sinus,2 eases in the convexity of the brain,1 ease in the sphenoidal erest,1 ease in the tentoriam of cerebellum the main findings were as followes: 4 eases were cystic tumores with obvious enhancement in the substant parts; 2 eases were shown as eystoma with the wall knot enhanced obviously; cystic tumores were found in 2 eases with the wreath form enhance; peritumoral edemaarea in 2 ease, hyperostosis were seen in 3 eases.

结果 本组8例囊性脑膜瘤均为良性，肿瘤位于镰旁／窦旁4例，大脑凸面2例，蝶骨嵴1例，小脑幕1例。其主要CT表现有：囊实性肿块，实质部分强化明显，4例；有壁结节的囊性病变，增强时壁结节强化明显，2例；环形强化的囊性肿块2例；瘤周伴水样低密度区2例，邻近骨质增生硬化3例。

Results Metaphysis osteoporosis was observed on X-ray and CT in acute stage, the midsection of infarct of bone was isointensity on T1WI and iso/hyperintensity signal on T2WI, the edge of infarct of bone was ring-shaped hypointensity on T1WI and hyperintensity signal on T2WI. Small worm-eaten change and stippled calcification was observed on X-ray and CT in subacute stage, the infarct of bone was iso/hypointensity on T1WI and iso/hyperintensity signal on T2WI, the edge of infarct of bone was ring-shaped hypointensity on T1WI and hyperintensity signal on T2WI. Irregular and wriggle osteosclerosis was observed on X-ray and CT in chronic stage, was hypointensity on T1WI and T2WI.

结果 骨梗死急性期X线、CT表现为干骺端骨质疏松，MR T1WI骨梗死灶中央部分呈等至高信号，T2WI呈高信号，T1WI骨梗死灶边缘呈环形低信号，T2WI呈环形高信号；亚急性期X线、CT表现为小的虫噬样改变，伴有斑点状钙化，MR T1WI骨梗死灶呈等或低信号，T2WI呈等或稍高信号，T1WI骨梗死灶边缘呈环形低信号，T2WI呈环形高信号；慢性期X线、CT表现为不规则状、蜿蜒状骨质硬化，MR T1WI和T2WI均呈低信号。

The experiments showed that, the surface microstructure is plate martensite, and the subsurface microstructure is cryptocrystalline martensite. the transition zone contains mixed martensite, troostite and part of the nonmelting ferrite.

实验表明：改性层微观组织由表层至基体依次为：表面熔凝区为片状马氏体；均匀相变硬化区为隐晶马氏体；过渡区为混合马氏体、屈氏体和部分未熔的铁素体。

objective to study mri diagnostic value on multiple sclerosis.methods mri examination data of 31 patients with multiple sclerosis were analysised retrospectively.results total 184 lesions were detectived in 31 patients.most lesions were located on white watter area beside the lateral ventricle,and a few lesions were located on the spinal cord,cerebellum,brain stem and corpus callosum.the shape of lesion can be circle or ellipse.the lesion showed as slightly long t1 and long t2 signal.the acute stage lesions can have enhancement.conclusions ms have characteristic findings on mri image.mri can show the patholoic changes,and provide strong evidence for clinic diagnosis of multiple sclerosis.

摘 要］目的：探讨多发性硬化（muliplle sclerosis，ms）的mri特征表现及其诊断价值。方法：回顾分析31例临床诊断为ms患者的mri检查资料。结果：31例共发现病灶184个，病灶于侧脑室旁白质区、半卵圆中心及皮层下区最多见，其次见于脊髓小脑、脑干及胼胝体，部分可见视神经受累，病灶呈卵圆形或圆形稍长t1、长t2信号，矢状位像见病灶与侧脑室垂直，急性病灶增强扫描有的可呈结节状、环状或斑点状强化。结论：在mri图像上ms有特征性表现，mri能反应ms病理变化，为临床诊断ms提供可靠依据。

Results Microscopically, the tumor cells were epithelioid or short spindled and special nests of tumor cells separated by arboring fibrovascular septa. Such morphological variants of CCSK as myxoid degeneration, microcysts formation and sclerosing pattern of extracellular hyalined collagen simulating osteoid were present in some regions.

结果 镜下见瘤细胞为上皮样或短梭形，被分枝状纤维血管间质分隔成巢团状，部分区域见黏液样变性微囊肿和细胞外胶原玻璃样变类似骨样组织的硬化型等形态变异。

The die's cutting and forming sections typically are made from special types of hardenable steel called tool steel.

模具的切割和成型部分通常是由特殊类型的硬化钢呼吁工具钢。

In the samples containing aluminum sulphate, some ettringite crystalparticles are formed, which do not match with dihydrate gypsum crystals and increase thedefects in the hardened plaster. The strength decreases sharply with increase of aluminumsulphate amount.

硫酸铝的引入，使石膏浆体中生成部分钙矾石晶体，钙矾石晶体与二水石膏晶体不匹配，从而增加了硬化体内部的缺陷，因此，随着硫酸铝掺入量的增加，硬化体强度的降低比较严重。
