The main purpose of this null modem cable is to let well defined software think there is handshaking available, with a null modem cable which has no provisions for it.

这个电缆的主要目的是让设计良好的软件认为握手正常。

SQL NULL values are mapped to and from Python's NULL object, None.

SQL 的 NULL 值被映射为 Pyhton的 NULL 对象，也就是 None。

Once you have inserted a null into the container, you must always check if the value is null before accessing the object

一旦你向容器插入了一个 null，你就必须在访问该对象前检查它是否为 null

Of zero, or the Null object None.of zero, or the Null object None.

空对象、值为零的任何数字或者Null对象 None的布尔值都是False。

In general, the dipole components are located at the zero potential plane, called null plane. However, for 3D topographic mapping, many zero potential points can be detected. Instead of testing all the possible points, the proposed approach is to fit the selected zero potentials in terms of a linear plane, i.e. null plane, via least square approach.

一般来说，电偶极的位置都在零电位面上，为了取得零电位面，本研究在三度空间拓朴图映射中找出多点零电位点，然后采用最小平方法，找出一个线性平面通过这些零电位点当做零电位面。

NULL is the value of a null pointer constant.

NULL 是固定空指针的值。

In C, NULL is defined as a null void pointer.

在C中，NULL 定义为一个null void指标。

In pointer context, the integer constant zero means "null pointer"- irrespective of the actual binary representation of a null pointer.

本节将指导您一些 C++中积灰尘的角落，这些往往被滥用，或是人们常常出错的地方。

The buffered-crossbar switch architecture is studied. In this paper, the maximum weight fast algorithm is used in BX, we discover the null row phenomenon in BX's maximum weight fast algorithms, and propose a doubling weight solution for null row, this promotes the performance of maximum weight fast algorithms in BX.

对缓冲Crossbar交换结构进行了研究，论文中将最大权重优先算法应用于BX结构，并对其在BX结构由于存在空列现象所导致的性能恶化提出了空列权重加倍的解决方案，提高了最大权重优先算法在不均衡负载下的性能。

If any variable element is a null string, the result propagates the non-null elements

如果有变量元素为空字符串，则结果只含非空元素

The system can be widely used in belt weighing and batching process control,etc.

介绍了基于智能模糊控制的嵌入式配料系统的设计方法，对模糊PID控制过程和系统调零作了重点的讨论，同时给出了PID控制的程序流程图和系统定长调零子程序。

"I dunno," she answered,"but if you show me aroun', I'll recognize it from the lighthouse just outside the porthole."

"我不知道，"她回答说，"如果你能带我转转，我能认出来的，因为灯塔就在舷窗外。"
