弓形

This paper briefly introduces the area calculation problem of a block,the boundary of which includes the easement curve or its parallel curve .

该文论述了以缓和曲线平行线为边界的地块面积的计算特点，推出了缓和曲线或其平行线弓形面积的严密计算公式，讨论了已知缓和曲线平行线弧长或坐标值计算弓形面积的问题，给出了相应的算例。

Objective To obtain the functional fusion protein of rhoptry protein 2(ROP2) and major surface antigen 1 of Toxoplasma gondii in order to further prepare for the diagnosis and polyvalent vaccines of toxoplasmosis.

目的构建编码弓形虫RH株棒状体蛋白2(ROP2)和主要表面抗原1的重组表达质粒，纯化和复性的融合蛋白为弓形虫病快速诊断试剂盒及蛋白质疫苗的研制作准备。

The bow-wave, the region of disturbed air around aircraft engines, could damage a tailplane if the engines were located near it,so tailplanes of rear-engined aircraft are mounted above the jets, often above the fins.

如果平尾装在接近弓形波，也就是飞机发动机周围产生干扰气流的区域，弓形波就会破坏平尾，因此发动机装在机身后部的飞机的平尾被安置在喷气机的上面，通常是在垂尾的上面。

The origins of the more irulent strains of Toxoplasma were first documented in a 2001 Science paper from Boothroyd's group; the researchers found that the recombination of two relatiely benign strains of Toxoplasma can result in a thousand-fold increase in their ability to cause serious disease.

Boothroyd等人在2001年《科学》的文章中记载了弓形虫毒性菌株的来源，他们发现将两种相对良性的弓形虫菌株重组后，新菌株的致病性呈千倍上升。

In countries where toxoplasmosis risk is moderate, all newborns are screened for toxoplasmosis infection.

在弓形虫病风险为中等的国家，所有的新生儿都被安排进行弓形虫病的筛查。

Methods The antimicrobial peptides of housefly larvae were induced largely by infection and injury, which were isolated and purified by trituration, centrifugalization and column chromatography. Then the antimicrobial peptides with anti-Toxoplasma activity were sieved by methyl thiazolyl tetrazolium colorimetric method and haemacytometry. The DNA contents of T.gondii tachyzoites were detected by flow cytometry.

通过损伤加感染的方法诱导家蝇幼虫大量表达抗菌肽，然后经过研磨、离心和层析等过程，分离纯化并筛选出抗弓形虫作用的抗菌肽，采用流式细胞术分析其对弓形虫速殖子DNA含量的影响。

Toxoplasmosis is zoonosis. The effective integrated control measure is to change people's bad habit and arouse their safety consciousness.

结论弓形虫是人畜共患病，应采取有效的综合防制措施，加强宣传，改变人们的不良习惯，提高个人防护意识，可降低人群弓形虫感染。

Of medium length, broad between the ears; forehead line seen in profile is moderately arched; zygomatic arch and stop well developed with strong broad upper and lower jaws.

中等长度的，在耳朵时间的部位：从侧面看前额线是适度的弓形；颊骨的弓形结构和强硬的宽的上下咽喉。

The decidual NK cells were collected and cell subset change of the two groups was analyzed by flow cytometry.

目的通过检测弓形虫感染后早孕蜕膜自然杀伤细胞亚群的变化，探讨其与弓形虫感染致不良妊娠结局的相关性。

Results In 30 sera with anti-Toxoplasma IgM antibodies and 28 with IgG antibodies, the sensitivity for IgM and IgG antibody detection was 90.0%（27/30） and 85.7%（24/28） respectively, the specificity was all 100% in examining 40 healthy control sera, and the Youden index was 0.9 and 0.86 respectively.

结果 用免疫印迹试剂盒检测30份弓形虫IgM和28份IgG阳性血清，敏感性分别为90.0%（27/30）和85.7%（24/28），40份健康对照者血清的弓形虫IgM和IgG抗体均为阴性，特异性均为100%，Youden指数分别为0.9和0.86。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
