无保护的

And, despite the "odds" out there, it IS possible to get HIV from only ONE episode of unprotected hetero sex.

而且，尽管几率很低，但是一次无保护的异性性行为是有可能导致感染的。

At the same time, we studied population dynamics of seed-eating rodents in the autumn and the following spring. The results showed that, without enclosure protection, most of the seeds were predated due to high predation pressure in the autumn. The emergence rate of seedlings of all the studied species significantly increased under autumn protection, complete protection, and 1-4cm burial under soil covered by litter.

结果表明：秋季鼠类对种子的捕食压力大，使得种子在无保护的情况下很少存活到出苗；而秋季覆网保护和完全保护（覆网一直保留到第二年10月调查时为止）均增加了直播种子的存活和出苗率；将种子埋藏在土壤1-4cm也显著增加直播种了的存活率和出苗率，这与鼠类密度(12%)在秋季显著高于春季(2%)有直接关系。

Trichomoniasis is caused by infection with the germ Trichomonas vaginalis. This usuallyhappens during unprotected sex with an infected partner.

滴虫病是造成感染的细菌阴道毛滴虫，这通常发生在无保护的性行为与受感染的合作伙伴。

Drench:The marid''s touch puts out torches,campfires,exposed lanterns,and other open flames of nomagical origin if these are of Large size or smaller.

浸湿：水巨灵的触碰可以熄灭火炬、营火、曝露在外的灯火，以及其它大型或更小的非魔法且无保护的火焰。

In order to improve its effect,by simulating natural enviroment and irradiating the material of FRP under water with strong ultraviolet ray for a long time,the strength change in protection and nonprotection conditions is contrasted and the weather resistance is analyzed.

纤维增强复合材料在土木工程中越来越得到广泛应用，为了更好地发挥其使用效果，通过模拟自然环境，将其材料在水下经长时间强紫外线照射，对比有保护和无保护情况下的强度变化，进行耐候性分析研究，结果表明有保护情况下强度保持率有了明显提高。

High risk *** with a know POZ person. i.e. unprotected anal ***.

与已知HIV阳性者发生高危性行为的；比如：无保护的GJ，应该在6个月后检测。

Wedge gate valve is usually no valve chamber overpressure protection 2, no clear protection bar gate, not recommended.

契形闸板阀通常没有阀腔超压保护 2、无保护的明杆闸阀，不推荐使用。

In total almost 19,000 instances of unprotected oral sex were estimated to have occurred involving the 135 couples over the ten years of the study, but not a single case of HIV transmission was detected.

在长达10年的研究中，估计135对夫妇总共发生了约19000次无保护的口交，但没有发现一例HIV的感染。

However, these studies should not be interpreted to mean that being the top during anal intercourse – and not using a condom – is without risk.

但这些研究不应该也不能被解释为插入方在无保护的GJ中没有危险。

Having unprotected receptive anal or vaginal intercourse with an HIV-positive partner is a documented risk, as they have been shown in numerous studies to be an independent risk factor for HIV infection.

同HIV阳性患者进行无保护的接受性GJ或者YJ是被实践证实的，因为他们作为独立的风险因素出现在很多的研究中。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
