But the space is the matter, the matter is the string vibration, only has from this the time which vibrates f=1/T to draw out only then has the physics significance, therefore T is in the true significance time, from this deduction: What imaginary number Ict expresses is void, may write *ct,=I pure imaginary number, also is it with Number space Sigma (x1i*x2j)(i, j is subscript, i=j=1,2,3) differs 90 in the space, the shape for example: Psi ==a+Ib, constitutes a duplicate space by psi i* psi j,(definition mark * for ordinary multiplication) may use Four single numbers

而空间就是物质，物质就是弦的振动，只有从这个振动f=1/T引出的时间才有物理意义，所以T才是真正意义上的时间，由此推论：虚数Ict所表达的是一个虚空间，可以写成*ct，=I纯虚数，也即它与实空间Σ(x1i*x2j)(i，j为下标，i=j=1，2，3)在空间上相差90度，形如：ψ==a+Ib，由ψi*ψj构成一个复空间，可用四元数

This invention is to provide a telephone exchange capable of operating any one of the juxtaposed and registered extension radiotelephones and wire telephones by only specifying one extension dial number. For this purpose, a wire port physical number is registered in association with a radio port physical number so that two normally separate extension wire telephone (006a, 006b, etc.) and radiotelephone (008a, 008b, etc.) can be handled as if they were a single-channel extension phone with a branch switch.

本发明是为了提供这样一种电话交换机：只需指定一个分机拨号号码，便可使用并置的和被注册的分机无线电话和分机有线电话中的任何一个，因此，有线端口的物理号码和无线端口的物理号码被联合注册，这样，两个在常规上是分离的分机有线电话（006a，006b……）和分机无线电话（008a，008b……）可以象具有一个分支切换a branch switch）的单通道分机电话一样来被处理。

Wheel' pattern were shown around mixed fibrous filter membranes, number of vessel ramification was 112.5±11.31 and ratio of vessel area/CAM area was 6.19±1.29﹪, but there were not localized allantoic vessels developing in the control group, the number of vessel ramification and ratio of vessel area/CAM area in control group were 82.6±8.05 and 1.78±0.33 respectively, so there was significant difference between PMP and control groups. In above mentioned conditions, the number of vessel ramification and ratio of vessel area/CAM area in VEGF group were 128.4±10.02 and 7.44±1.36 respectively, so there was no difference between PMP and VEGF groups.

结果显示：当 PMP的浓度为80 μg/ml时，孵育72小时后混合纤维素滤膜周围可见到放射状密集生长的血管网，血管分支数为112.5±11.31 ，血管面积为（6.19±1.29）﹪，而在对照组无特异性密集血管生成，血管分支数为82.6±8.05，血管面积为1.78±0.33，二组比较有显著性差异（P＜0.05）；而与VEGF组比较，后者的血管分支数为128.4±10.02，血管面积为7.44±1.36，二组比较差异无显著性。

METADATA\SPECSPK\SPKINFO. In it, there are information of the speakers, such as sequence number of each speaker, serial number of the dialect each one used, their name, age, sex, educational background, contact telephone number, time of recording, topic for spontaneous monologue, coverage and degree of noise of recording room, level of Putonghua proficiency, and etc..

After a collision, a station chooses a random number between 0 and 2 i -1, where i is the number of times that particular packet has been in a collision, and waits that number of slots, before attempting to retransmit.

在碰撞以后，驻地选择一个随机号在0 之间和槽孔的数字，在试图之前转播的2 i -1， i 是特殊小包是在碰撞的次数的地方，并且等待。

The results showed that "Green Drought Resistance agent NO.1, NO.2 and NO.3" harmonized ear number, spike number and 1000-seed weight of winter wheat in dry land, they have good yield-improving effects. The drought-enduring experimentation showed that with the raising of the PEG density, the restrain that burgeon and rootage got on each treatment were more obvious. The drought resist of burgeon ratio, length of bud, rootage ratio, number of root and length of root treated by GDR1 was better than check's.

结果表明：GDR1号、GDR2号和GDR3号抗旱剂较好地协调了旱地冬小麦的穗数、穗粒数、千粒重，具有较好的产量效应；耐旱性试验表明，随着PEG浓度的增高，各处理发芽和生根受到抑制作用越明显，GDR1号处理的发芽率、芽长、生根率、根数和根长的抗旱性优于对照；不同土壤水分条件下绿色抗旱剂GDR1号的出苗率、幼苗和根系生长与不同PEG浓度条件下的处理结果相一致。

Healthy spikes of high-resistant varieties had thicker cell wall and tissue of cortical sclerenchyma, more number of cortical sclerenchyma layers, more number of fibrovascular bundles, smaller area of green subcutaneous tissue in rachis, and theses differences, except number of fibrovascular bundles, enlarged over time. Considering inoculated spikes, cell wall and tissue layers of cortical sclerenchyma displayed different, and to how much extent the relationship between this difference and anti-extension ability of variety had not determined. 6. On the analysis of agronomical characters and molecular marking technology, more than 30 alien anti-Gibberella wheat materials and two mutants coming from this experiment were evaluated their hereditary multiplicity.

实验结果还证明，高抗品种和感病品种的穗轴组织结构确实存在一定差异，在健康穗中，主要表现在高抗品种的皮层厚壁细胞壁和皮层厚壁组织较厚，皮层厚壁细胞层数较多，维管束数目较多，穗轴表皮下绿色组织面积较小，抗、感品种间的差异达显著水平，随发育时间延长，高抗品种的皮层厚壁细胞壁厚度、厚壁组织厚度和厚壁细胞层数增加的幅度较大；在病穗中，主要表现在高抗品种的皮层厚壁组织细胞层数和厚壁细胞壁厚度增加的幅度较大。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
