Results Sera from 150 patients with schistosomiasis were detected, the average sensitivity was 84.7%(72.0%～91.0%). No false positive reaction was detected in 40 normal controls and none but 2 patients(2/10) with paragonimiasis showed cross reactions among 74 cases with other parasitic infections.

结果 用于检测 15 0例血吸虫病患者的循环抗原，其敏感性平均为 84.7%(72 。0 %～ 91.0 %)，40例正常人未出现假阳性反应，74例其他寄生虫感染者中，有 2例并殖吸虫病患者阳性，其余均未出现交叉反应。

We have shown that for an Al thickness of about 1.2 nm a transition from strongly ferromagnetically coupled Co and Ni80Fe20 characterised with single hysteresis loops to well separated magnetisation loops evident for weakly coupled layers occurs.

我们已显示，一·厚度，大约 1.2 的好分开磁化循环明显，-助学金网，因为弱耦合的层出现循环的纳米强烈 ferromagnetically 耦合的合作和 Ni80Fe20 转换特色的单一滞后。

Some technical problems arose during the debugging of the accelerator. The ion source did not produce arc. The accelerator tube cracked. The control system was out of order. The transporting capacity of the charge belt degraded. The corresponding reasons were analyzed and some measures were adopted to solve the problems. The drawing voltage was raised to its predetermined position after the ion source produced arc and should be reduced to zero before turning off the accelerator. Transition flange was lathed and the accelerator tube was re-assembled. The control equipment at high voltage was shielded. TVS diodes were installed at the input and output ends.

调试中出现了离子源不起弧、加速管破裂、控制系统失灵和输电带输电能力降低等技术问题，分析了出现这些问题的原因，然后分别采取了相应的措施加以解决：变换工作流程，在每次关机前先把引出电压降为零，开机时等离子源起弧后再把引出电压升到预定值；对过渡法兰进行车加工，重新封装；对高压端的控制设备采取屏蔽措施，在输入、输出端使用TVS二极管，对控制软件进行抗干扰设计；对绝缘气体进行循环干燥等。

Only in the special medium and using appropriate doges of scale inhibitors and corrosion inhibitor, the corrosion rate of copper-alloy can meet the standard of the state.

工业循环水系统中，为了防止系统中出现结垢腐蚀现象，常在循环冷却水中添加一定剂量的阻垢剂和缓蚀剂，然而阻垢剂在一定剂量范围内对铜合金也具有一定的腐蚀作用。

Both the fractures in air and vacuum, in which fatigue striations, steps and dimples are observed and more areas with the dimples exist under lower cyclic stresses.

真空和室温大气环境下的疲劳断口均出现疲劳条纹、台阶和韧窝，且在低循环应力时出现韧窝的区域增多。

Several main results on the evolutions of the life and environment on early earth are summarized as follows:(1) the oxygenation of surface environment didn''t cease until a stable stage for 0.4Ga appeared after 1.6Ga;(2) compared to the isotopic compositions of kerogens and coexisted carbonates, the differences between two can effectively carrier the signals from local environments and bio-assemblages;(3) multiple isotopic relationships between kerogens and individual alkanes in Proterozoic samples were observed, which would depend on the specific biogeochemical processes;(4) repeated biogeochemical changes were observed accompanying Neoproerozoic glaciations, which suggesting that environmental rather than evolutionary forces were driving the biogeochemical changes;(5) the bio-radiations after Neoproterozoic glaciations were definitely suggested by molecular and isotopic data to be at the early Cambrian and after the middle of Doushantuo deposition with different triggers for them.

研究获得以下重要认识：（1）古元古代地表环境的氧化可能一直持续到中元古代早期(约1.6Ga)，而在此之后的4亿年里则保持相对稳定；（2）相对于传统的干酪根和碳酸盐的碳同位素组成，二者之差则能更好反映区域环境的演化特征；（3）在元古代干酪根与单体烷烃类之间存在多种碳同位素组成关系；而其与不同的生物地球化学过程有关；（4）全球海洋生物地球化学特征随新元古代多次冰期出现循环波动，这显然为环境因子的驱动；（5）在新元古代大冰期之后，分子与同位素数据显示地球生命在陡山沱中后期和早前寒武纪出现两次大辐射，然而两次生命辐射的本质却是不同的。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
