Using potato tubers of Irish cobbler variety naturally infected with X- and Y-virus, the writer compared the concentrations of X-virus in the young sprouts of different seed pieces longitudinally cut from the same tuber and subjected to various temperatures, light and darkness, normal and dereased oxygen tensions during the period of germination.

在定温箱内所做的发芽温度试验的结果指出，块茎在20℃中发出的幼芽内X-病毒的浓度最高，沉淀滴度一般在1/80—1/160之间，最高的达到1/320，千日红上平均半叶斑点数目约为30.16°及24℃中的病毒浓度相近，沉淀滴度约为20℃的1/2，斑点数目达20℃的2/3左右。28℃发出的幼芽内病毒浓度最低，平均沉淀滴度约在1/10—1/20之间，平均半叶斑点数目为11.9。

Similarly, a graph X is said to be hyper-connected if every minimum vertex cut creats two components, one of which is an isolated vertex. In [8], D.Wang and J.

类似地，一个图X称为是超连通的，如果对每一个最小割集C，都有X—C只有两个连通分支，且其中一个连通分支为孤立点。

In LISP, most variables are lexically scoped; that is, if foo calls bar and bar tries to reference x, bar will not get foo's value for x.

在LISP中，大部分的变量都是局部的，如果 foo 调用了 bar ，bar中虽然使用了名字为x的引用，但bar 得不到 foo 中的

The set of divergence points is defined as following : we obtain that either all has the same limiting point or the topological entropy of the divergence points is as big as the whole space x .

我们得到如果不是所有的点x x ，{ l _ nx }有相同的极限点，则d的拓扑熵和整个空间的拓扑熵相同。

Moreover, when the x in LiMn(subscript 2-x)LaO4 was less than 0.04, high capacity can be observed.

而且当掺杂量x≤0.04时，材料有较高的放电比容量。

Therefore, we designed a measurement based on the measurement of grating XY table to meet the measurement of the rail line rolling X, Y coordinates of the accuracy requirements.

因此，本文设计了一种基于计量光栅的计量型X-Y工作台，满足了测量直线滚动导轨对X，Y坐标精度的要求。

Then, straight from the starting point, to determine the best approach in a straight line y coordinates are integers, and let X from start-to-end change, every step an increase, calculated corresponding y, y = Response kx B, and admission pixel x, round

然后，从直线的起点开始，确定最佳逼近于直线的y坐标均为整数，让X从起点到终点变化，每步递增1，计算对应的y坐标，y=kx+B，并取象素。
