部分硬化的

In the first part of this study, the effect of beam hardening-induced cupping artifacts on BMD measurements was examined.

在这项研究中的第一部分，监测了由线束硬化产生的杯状伪影对骨密度测量的影响。

Not the violent conflict between parts of the truth, but the quiet suppression of half of it, is the formidable evil; there is always hope when people are forced to listen to both sides; it is when they attend only to one that errors harden into prejudices, and truth itself ceases to have the effect of truth, by being exaggerated into falsehood.

可怕的祸患不在部分真理之间的猛烈冲突，而在半部真理的平静压熄。这就是说，只要人们还被迫兼听双方，情况就总有希望；而一到人们只偏注一方的时候，错误就会硬化为偏见，而真理本身由于被夸大变成谬误也就不复具有真理的效用。

Results (1) 6 cases of Tuberous Sclerosis. Diffused subependymal nodular calcification lesions were found in all cases on unenhenced CT. 4 patients are 2 pairs of mother/child relationship. Both of the two mothers are found to suffer from renal angiomyolipoma.(2)1 case of neurofibromatosis showed abnormal spinal canal: scoliosis of thoracic and lumbar spine, concave change of vertebral posterior border. Bilateral renal hypogenesis was found in this patient. Diffused hyper-density lesions were found in kidney and fatty accumulation was found in back skin.(3)6 cases of Sturge-Weber syndrome. On unenhenced CT, curving and strip-shaped calcifications were found along the parietal and occipital gyrus.

结果 ①结节性硬化6例，所有病例CT平扫见两侧脑室室管膜下多发小结节状高密度钙化灶，其中4例为两对母子关系，并见两位母亲合并有肾脏错构瘤，；②神经纤维瘤病1例，MRI表现为椎管异常，胸腰段脊柱侧弯，椎体后缘呈明显的切凹改变；伴有双肾发育不良，CT示肾内多个高密度影，背部皮肤多量脂肪堆积，③脑颜面血管瘤综合征6例， CT可见顶枕部沿脑回分布的弯曲的条状高密度钙化，部分延伸致侧脑室内，增强后见病灶内有扭曲的条状和结节状明显强化的血管影；④小脑血管瘤病4例，影像学表现为小脑内大囊、小结节样占位性病变。

Background— Numerous in itro studies suggest that sphingosine 1-phosphate (S1P), a bioactie lysosphingolipid associated with high-density lipoproteins, accounts at least partly for the potent antiinflammatory properties of high-density lipoprotein and, thereby, contributes to the antiatherogenic potential attributed to high-density lipoproteins.

背景——众多的活体研究表明鞘氨醇1-磷酸盐作为一种与高密度脂蛋白相关的生物活性溶血磷脂，至少是高密度脂蛋白有力抗炎特质的部分原因，从而促成高密度脂蛋白的抗动脉粥样硬化潜能。

In alloy steels the kind and amount of alloying element influences only the hardenability (the ability of the workpiece to be hardened to depths) of the steel and does not affect the hardness except in unhardened or partially hardened steels.

除了非淬硬钢或部分淬硬钢外，合金钢中合金元素的种类及含量仅影响钢的淬透性(工件被硬化到深层的能力)而不影响硬度。

This is an important distinction, since certain conditions are or may be hypopigmented such as tinea versicolor, nevus anemicus, leprosy, hypomelanotic macules of tuberous sclerosis, hypomelanosis of Ito, seborrheic dermatitis, and idiopathic guttate hypomelanosis.

比正常皮肤颜色浅的斑片可能是完全或部分丧失了色素，这是一个重要的特征，因为某些疾病可能是色素减少的，如花斑癣、贫血性痣、麻风、结节性硬化性色素减少性斑疹、伊藤黑素减少症、脂溢性皮炎、特发性点滴状色素减少症。

Patches lighter in color than the normal skin may be completely depigmented or have lost only part of their pigment. This is an important distinction, since certain conditions are or may be hyposigmneted such as tinea versicolor, nevus anemicus, leprosy, hypomelanotic macules of tuberous sclerosis, hypomelanosis of Ito, seborrheic dermatitis, and idiopathic guttate hypomelanosis.

比正常皮肤颜色浅的斑片可能是完全或部分丧失了色素，这是一个重要的特征，因为某些疾病就可能是色素沉着减少的，如花斑癣、贫血性痣、麻风、结节性硬化性低色素性斑疹、伊藤黑素过少症、脂溢性皮炎、特发性点滴状色素减少症。

By 666 B.C. the process of casehardening was in use for the edges of iron tools, but the story that the Egyptians had some secret means of hardening copper and bronze that has since been lost is probably without foundation.

大致公元前666年。表面硬化方法用于铁工具刃口，但是埃及人的传说有部分秘密，意指铜和青铜的淬火，没有根据可能工艺已经失传了。

Then are seen the cases, so frequent in this age of the world as almost to form the majority, in which the creed remains as it were outside the mind, incrusting and petrifying it against all other influences addressed to the higher parts of our nature; manifesting its power by not suffering any fresh and living conviction to get in, but itself doing nothing for the mind or heart, except standing sentinel over them to keep them vacant.

于是就出现了在这个世界这个年代经常出现以致形成多数的这种情事：信条之存在竟象是存在于人心之外，其作用只在把人心硬化和僵化起来以挡住投给人性更高部分的一切其他影响；其力量只表现在不容任何新的和活的信念进入人心，而其本身则除作为一名哨兵监守心脑使其空虚以外也对它们别无任何作为。

In precision alloy (soft, including Nd-Fe-B rare earth permanent magnet materials, including, expansion, flexibility, hot bi-metals, electric resistance), high temperature alloy and stainless steel (Ni-Cr system, precipitation-hardening grades, grade maraging ) materials and products in research, development, trial and production areas such as the domestic advanced level, some products up to international standards.

在精密合金（软磁、包括钕铁硼及稀土材料在内的永磁、膨胀、弹性、热双金属、电阻电热）、高温合金和不锈钢（镍铬系、沉淀硬化系、马氏体时效系）材料及制品的研究、开发、试制和生产等方面居国内先进水平，部分产品达到国际水平。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
