同位素

In this paper the development and the latest research progress of nuclear battery materials has been introduced from the view of radioisotope, electric energy conversion and encapsulation.

从同位素放射源、电能转换、密封保护的角度介绍了核电池所用材料的发展和最新研究进展，同时也介绍了核电池现有和潜在的应用领域。

Treatment of disease with radiation,especially by selective irradiation with x - rays or other ionizing radiation and by ingestion of radioisotope s.

放射疗法用放射进行的疾病治疗，尤指用X射线或其它电离辐射的有选择放射和吞下放射性同位素

The surface temperatures of the radioisotope target capsule is one of the important parameter to its structure integrity.

放射性同位素辐照靶件在堆内辐照过程中能否保持其完整性，受到诸多因素的影响，其中辐照靶件包装容器外壁温度和内腔温度是辐照安全的重要参数。

Then the blast of radiation emitted by the radioisotope would destroy the…tumor cells nearby.

于是，放射性同位素发出的辐射冲击将会破坏邻近的肿瘤细胞。

The addition of a radioisotope to the antibody is thought to offer another way to kill a cancer cell, and nearby cancer cells, with minimal toxicity to normal cells.

抗体上添加了放射性同位素，这被认为是提供了另一种杀死癌细胞及其周围细胞，而对正常细胞毒性最小的方法。

Third, gas leaks, including helium from the spacecrafts' radioisotope thermoelectric generators has been viewed as possible causes.

第三，气体泄露，包括探测器的放射性同位素热电发生机泄露的氦也被视为一种可能的原因。

The osteoid osteoma was found to have a circular or oval radiolucency which was less than 2 cm in diameter with different degrees of bone sclerosis around the nidus. Of the 9 cases, 5 showed an irregular area with less density on plain X-ray film. CT scanning showed nidus in all cases. MRI showed nidus in 1 case. Radioactive scanning showed radioactive concentration in 4 cases.

骨样骨瘤的影像学表现为一圆形或卵圆形的透亮区，直径cm，其周围有不同程度的骨质硬化。9例X线平片仅5例发现不规则密度减低区，9例CT均清楚显示病灶瘤巢； 1例MRI也观察到类似瘤巢的改变。4例同位素检查均表现为病变区核素浓聚现象。

Lisa Raitt, the minister responsible for AECL, apologised to cancer patients after she was caught on tape discussing how her career might benefit if she solved the "sexy" isotope crisis.

负责加拿大核能公司的内阁部长Lisa Raitt谈话被偷录，谈话内容是其职业生涯是否会因解决"万众瞩目的"同位素危机而有所裨益。

Interpretation of this or of any novel is always a danger）,but because Wuthering Heights has recalcitrant

差；而最初的研究表明，对於自单独一个铜矿石源的铅，其同位素构成几乎是毫无二致的。

He results of TPR and 18O-isotope exchange experiments demonstrated that the excellent activity of Pd/2Ti-3Al was due to its high oxygen mobility and moderate reducibility, which is in accordance with our previous work.

PR和18O同位素交换的结果表明Pd/2Ti-3Al高的催化甲烷燃烧活性是由于其高的氧交换活性和适中的还原性，这也符合我们前面工作中的结论。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
