这个方法的问题是选择哪个服务器来储存键/值对，以及当想要重新获得一个值时，如何决定要与哪个memcached 服务器对话。
The problem with this approach is choosing which server to store your key/value pair on and how you determine which memcached server to talk to when you want to recover a value.
磷链构成DNA的骨架及其化学键，特别是在一种叫做三磷酸腺苷的分子中。 三磷酸腺苷是生物体储存能量的一种重要形式。
Phosphorus chains form the backbone of DNA and its chemical bonds, particularly in a molecule known as adenosine triphosphate, the principal means by which biological creatures store energy.
答题者的姓名作为查询储存库的键。
The names of the respondents serve as keys to query the repository.
一个理想的替代方法是生产液态碳氢化合物如醇，使更多的能量可以储存在碳碳键里。
A desirable alternative is to produce liquid hydrocarbons such as alcohols, as far more energy can be stored in the carbon-carbon bond.
一旦应用成功扫描和储存了钥匙信息，用户可通过应用的“分享键”将其数字钥匙链发送给亲朋好友和室友。
Once a key is successfully scanned and stored, users can send their digital keychain to friends, family and housemates over email, using the app's 'Share' button.
三磷酸腺的化学键中储存了大量的化学能。
ATP's chemical Bonds store a large amount of chemical energy.
施加高电压是一种能量损失，这意味着制造一氧化碳所需的能量比其化学键中储存的能量要高得多。
That excess voltage is an energy loss, meaning it takes far more energy to make the CO than it can store in its chemical bonds.
例如，建立新的客户和新的订单，然后尝试储存资料，会导致资料库中所定义的外部索引键条件约束发生冲突。
For example, creating a new customer and a new order and then trying to save the data can cause a conflict with the foreign-key constraints defined in the database.
