查询词典 have a point

Different chemicals have different spectrographic signatures, but those of water and hydroxyl are very similar. Therefore, the scientists can't exactly distinguish whether it is a hydroxyl or water at this point. Nevertheless, the findings overturn long-held beliefs that the surface of the moon was dry and further pave the way for scientists to one day set up a permanent research base on the moon.

不同化学成分会有不同的光谱特徵，但是水和氢氧根的光谱特徵却十分相似，因此科学家目前还无法确实判断月球上的成分到底为氢氧根还是水，尽管如此，这项发现颠覆了长期以来月球表面无水的认知，且更进一步地为科学家将来有一天能於月球上设置长驻研究基地铺路。

Methods and Results-: We enrolled 142 patients randomized at a single center to have either the radial artery or saphenous vein grafted to a stenosed branch of the native left circumflex coronary artery. The primary end point was angiographic graft patency 5 years postoperatively.

方法和结果：我们通过单中心随机试验对左冠状动脉狭窄进行桡动脉或隐静脉移植的142例病人进行研究，主要的终点利用血管造影对移植的血管进行监测5年。

It is worth noting that, although Cope described his Perosuchus as lacking a supraorbital ridge, his description was based on a single juvenile obtained by the Academy of Natural Sciences of Philadelphia, and therefore he could easily have been mistaken on this point.

值得一提的是，尽管对抗的描述了他Perosuchus缺乏眶上脊，他的描述是基于一个单一的少年获得的自然科学院76 ，因此他可以很容易地被误解了这一点。

But the row has at least ensured that the question of openness in the cloud has received a lot of attention, observes Bob Sutor, IBM's point man for standards:"People have been put on notice that they can get locked into a cloud."

然而，这场激烈的争论至少确保了云计算的开放性问题得到了足够的关注，IBM云计算标准的核心人物 Bob Sutor认为：&人们已经意识到自己可能被一种计算云所限制。&

But the row has at least ensured that the question of openness in the cloud has received a lot of attention, observes Bob Sutor, IBM's point man for standards:"People have been put on notice that they can get locked into a cloud."

然而，这次激烈的争论至少保证了有关开放性的问题得到了足够的重视，鲍勃·萨克托，IBM在云计算标准方面的出头人，根据自己的观察，他认为：&人们已经注意到了自己有可能被锁在一片云里。&

And while it has been uncharitably said that such stylistically distinct photographers as Lee Friedlander and Larry Sultan and Tim Davis and Sally Mann and two or three dozen more have each taken a piece of Walker Evans' pie and inflated it into a comfortable career, it is much more to the point that Walker Evans brought to cogent maturity the visual dialectic with which much of the dialogue of contemporary American photography continues to be engaged.

人们有时会不甚厚道地说，几位风格独特的摄影家，例如李·费兰特、拉瑞·萨尔坦、迪姆·戴维斯，莎里·曼，还有更多类似的同行，全都从沃克·埃文斯那儿获得些许好处，然后过分地把摄影弄成了一个舒适的职业。

Use properly placed, properly made matched HUNTING arrows (matched to the bow/archer combination, and made for hunting; hunting arrows should be about 10 grains for every pound of draw, sometimes heavier - 400 grains for a 40 lb bow is a good starting point), with SHARP broadheads, and you won't have to worry about being "underbowed"-- as long as you pay to the local regulations where you hunt.

只要能准确的打中有效部位，用猎箭（每磅至少10格令，对初学者来说40磅的配400格令挺好的），用极锋利的猎箭头，你不用担心威力不足--参照各州法律规定在什么地方狩猎（译者说明，一般必须上树）。

Through simulation and computation, some critical values to contral interferences are obtained. These values have directive significance to the design and deployment of WRAN.(4) New methods to measure and analyze spectrum aredevelopedAccording to the shortages of previous spectrum measurements, new methods to measure spectrum occupancy in wide-band and multi-point synchronously is proposed in this dissertation, and the tests last a whole week; the relativities of licensed services are considered when test points are selected. More importantly, data mining and in-depth analysis are carried out with the huge amounts of test data, and a channel analysis method using Channel Vacancy Duration and Service Congestion Rate are proposed. The spectrum relativities of 3-dimension in time, space and frequency are researched also. The correlativity between channel state and history information is discoved, and which will provide the scientific basis to channel modeling, spectrum analysis and decision of CR users.

4提出了频谱测量与分析的新方法针对以前频谱测量工作存在的不足，本文提出了多点同时广域频谱测量方法，测量工作持续了一周的时间，同时考虑了测量地点的选取和频谱授权业务之间的相关性；对测量得到的海量数据进行了数据挖掘和深度分析，提出了使用信道空闲时间(Channel VacancyDuration，CVD)和业务拥塞率(Service Congestion Rate，SCR)进行信道分析的方法，研究了频谱之间的时间、空间、和频率三维立体的相关性，发现了信道状态和历史信息的关联性，为CR用户的信道建模、频谱分析和决策提供了科学的理论依据。

Not only is the holding of civil society is in full swing with a variety of activities to celebrate the Chinese New Year, and even central to a get-together look, although we have no chance at the scene to see these wonderful programs, but can still be adopted by the boiling point network television coverage of the actor playing the situation be aware of.

不光是民间正在如火如荼的举行着各种庆祝新春的活动，就连中央也要联欢一下，虽然我们没有机会在现场看到这些精彩的节目，但是还是可以通过沸点网络电视的报道对出场演员的情况有所了解的。

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）。
