Under no andheavy soil water stress, there"s a great change of Atriplex canescens"s physiologicalindexes, Tr and Cs increased while Pn, WUE and LS decreased, its growth andbiomass reduced substantially, which reveals it can hardly survive under extremelydry habitat.

在无土壤水分胁迫和重度土壤水分胁迫下各项生理指标变化显著，Tr、Cs增加和Pn、WUE、LS下降，生长量和生物量的大幅度下降，表明其在特别干旱的环境条件下难易生存。

Using kronecker product of matrix theory, basic link space code chips are recombined and a new kind of LS code is obtained.

对基本LS码片用矩阵中克罗内克积方法重新排列，得到了一类新的LS码，并从数学上证明了这类新码非周期自相关函数具有均匀的IFW，以及组内码字之间的IFW也是均匀分布的。

As a result, LS-OOC based on orthogonal Latin square has been acquired. The large cardinality of LS-OOC is beneficial to synchronous OCDMA system.
