The invention relates to a report sending method, which comprises: when receiving or sending the LSA refresh report, first judging if it and the nearby device have disperse equivalent chain group; if there is, only using the main disperse chain to send said report.

本发明公开了一种报文发送方法，该方法包括：在收到或发起LSA更新报文时首先判断与邻居设备间是否存在扩散等价链路组，如果存在则仅通过其主扩散链路发送所述报文。

The method involves exposing the cells to a compound having the formula I in which: w is a nucleic acid x is a non-amino acid or non-peptide nucleic acid binding group y is a spacer having a chain length equivalent to 1-30 carbon-carbon single covalent bonds or is absent R4 is H or halogen or CH2O-R3; and R1, R2 and R3 are the same or different and are either hydrogen, methyl, ethyl, alkyl, alkenyl, hydroxylated alkyl, hydroxylated alkenyl groups or ether containing alkyl, alkenyl, hydroxylated alkyl or hydroxylated alkenyl groups optionally being an acyl group having a carbon chain length equivalent to 3-24 carbon atoms saturated or unsaturated, with the proviso that at least one of R1, R2 or R3 includes a group having a carbon chain of 3-24 carbon atoms saturated or unsaturated, or to a compound having the formula II in which: w is a nucleic acid x is a non-amino acid or non-peptide nucleic acid binding group y is a space having a chain length equivalent to 1-30 carbon-carbon single covalent bonds or is absent, R5 is alkyl, alkenyl, hydroxylated alkyl, hydroxylated alkenyl group or ether containing alkyl, alkenyl, hydroxylated alkyl or hydroxylated alkenyl group optionally being an acyl group having a carbon chain length equivalent to 3-24 carbon atoms saturated or unsaturated, with the proviso that R5 includes a group having a carbon chain of 3-24 carbon atoms saturated or unsaturated.

该方法包括使细胞暴露于具有式的化合物，在式中：w是核酸，x是非氨基酸或者非肽核酸结合基团，y是具有等于1―30个碳―碳单共价键的链长的间隔基或者不存在，R4是H或者卤素或者CH2O－R3；R1、R2和R3是相同的或者不同的并且是氢、甲基、乙基、烷基、链烯基、羟基化烷基、羟基化链烯基或者包含烷基、链烯基、羟基化烷基或羟基化链烯基的醚，任选地是来源于具有等于3―24个碳原子的碳链长的饱和或不饱和脂肪酸的酰基，其条件是R1、R2或者R3的至少一个包括具有3―24个碳原子的饱和或不饱和碳链的基团，或者使细胞暴露于具有式的化合物，在式中：w是核酸，x是非氨基酸或者非肽核酸结合基团，y是具有等于1―30个碳―碳单共价键的链长的间隔基或者不存在，R5是烷基、链烯基、羟基化烷基、羟基化链烯基或者包含烷基、链烯基、羟基化烷基或羟基化链烯基的醚，任选地是具有等于3―24个碳原子的饱和或不饱和碳链的链长的酰基，其条件是R5包括具有3―24个碳原子的饱和或不饱和碳链的基团。

The evolution process with the change of a non-dimensional variable about the cantilever, Arc shaped beam and S shaped beam is investigated in this paper.

（1）文中：Arc型梁和S型梁已不再是悬臂梁；S型梁的悬空长度随着梁的均布载荷的大小而变，不存在临界悬空长度；Arc型梁不存在临界长度。

Monitoring data of rock slope collapse is a sort of uncertain and incomplete information, Furthermore, it is a discontinuous deformation system, which will branch off or be in critical state with the continuous change of dominant variable parameter, the Gray theory and catastrophic theory are more effective to predict time of collapse occurrence.

由于崩塌的监测数据存在信息不完全和不确知性，同时，崩塌的发生存在有突跳性，采用灰色理论和突变理论能够有效地预测预报边坡崩塌发生的时间，为崩塌防治提供及时的决策依据。

There has always been a big disparity between housing costs and wages in Charlottesville, because the presence of so many students and faculty drives up rents and house prices.

夏洛茨威尔的住房成本和工资之间一直存在着明显的差异，因为大量学生和教职员工的存在，推高了租金和房价。

For this purpose, genotyping was performed on males of 18 Angus, 23 Jinnan cattle, 20 Limousin, 28 Luxi cattle, 26 Qinchuan cattle, 29 Simmental, 29 Charolais. In the association studies traits of interest were analyzed using the RFLP-PCR and GLM procedure of SAS 9.1 and least square means of the genotypes were compared by the Tukey' s test.

基于这一目标，应用RFLP技术对18头安格斯，23头晋南牛，20头利木赞，28头鲁西牛，26头秦川牛，29头西门塔尔牛和29头夏洛莱牛进行了基因型分型，SAS 9.1的GLM过程中的Duncan's 检验对不同基因型之间进行了多重比较分析，结果表明，EcoRⅤ位点与体重、日增重、眼肌面积和嫩度之间存在显著生物学相关，并且AG基因型个体与其它基因型相比在日增重和嫩度上存在显著差异（p0.05），而AA基因型个体相对于其它基因型具有较大的眼肌面积（p0.05）。
