You probably faced a little problem one day: these data types do not support the Null value.

总有一天你会遇到这样的问题：这些类型不支持Null值。

Chart cannot display a numeric value, even if there are numbers in the fields, so the chart displays the COUNT function.

若要避免发生这个问题，请确定您使用的栏位具有数值资料类型，而不是包含格。。。

One part of the program throws an object of one of these types, and another part catches and handles the indicated problem.

程序的一个部分抛出某个这些类型的对象，程序的另一部分捕获并处理指出的问题。

The main conclusions from the works presented in this thesis can be as this: for the Galactic OH 1612MHz masers, the radiative pumping mechanism coexists with other mechanisms while some other unresolved problems need to be solved after the launch of more advanced space infrared spectrometer and the more reliable identification of the evolutionary status of the maser bearing infrared sources;the asymmetrical 53.3μm absorption line profile could become a powerful tool to assist us to observationally discriminate the radiative pumping mechanism from other pumping mechanisms in the OH masers.This is the English version of my PhD thesis.

通过本论文的研究工作，我们可以得到这样的结论：在银河系内的OH 1612MHz脉泽中，辐射抽运机制与其它抽运机制并存，而还有一些未解决的问题需要等待更先进的空间红外光谱观测设备的使用并与天体类型证认工作相配合加以解决；不对称的53.3微米吸收线轮廓特征有可能成为帮助我们从观测上对OH脉泽的辐射抽运机制加以鉴别的有力工具。

The third member of Dongying Formation Oligocene (Ed3) is one of the major oil producing pays. As the oilfield developing, the contradiction between distribution of reservoir sandbodies and production practice becomes more serious. For further production, it is the key point to get better understanding of sedimentary characteristic and reservoir distribution.

随着油田开发的不断深入，储集体分布范围及规模与开采动态的矛盾日益凸现，对东三段III油组沉积相分布规律的认识以及砂体的微相类型确定与空间展布已成为制约下一步开发的核心问题。

The type of tree you pick depends on whether you want one for oil or for pickling olives.

你选择树的类型取决于你是想要油还是果的问题。

The style of this question will not be asked this year on the analogy of the test last year.

根据去年的测试类推，这种类型的问题今年不会再问了。

In OOP, users often define one data type after another, so this could be a serious problem.

在OOP中，用户经常一个又一个的定义数据类型，所以这会产生一系列的问题。

However, both of these kinds of strict organum had problems with the musical rules of the time.

然而，所有这些strict organum类型在当时的音乐规则上都存在一个问题。

However, if you are overwhelm ed by the number or types of answers you receive

但是，如果所收到问题的数量或类型太多

The split between the two groups can hardly be papered over.

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
