Let F=LF be a s-closed local formation such that every minimal non-F-groups is solvable. It is proved that 1 If every cyclic subgroup of of order 4 and every minimal subgroup of G are contained in, then G is a F-group. 2 If there exists a normal subgroup N of G such that G/N∈F and every cyclic subgroup of N of order 4 is weakly c-normal in G and every element of N of prime order is contained in Z(superscript f subscript ∞), then G is a F-group.

设F=LF是一个子群闭的局部群系，满足每个极小非F-群是可解群，证明了：1如果G的任意极小子群和任意4阶循环子群都含于Z中，那么G是F-群；2如果存在G的正规子群，使得G/N∈F，且N的任一4阶循环子群在G中弱c-正规，N的任一素数阶元含于Z中，那么G是F-群。

The original crystal configuration of KGM was destroyed, and the molecular structure was disordered. The glass transition temperature T(subscript g of TKGM was only 13.14℃, and there's an obvious melting decalescence peak at 102℃, the difference between decomposed temperature and melting temperature is above 200℃. This means that TKGM has a good thermoplasticization property.

A larger error often occurs in measured results by multi-specimen J-R curve method because of the difficulty in determining the blunting line equation. On the basis of considering the effect of loading rate on plastic-flow stress, a new blunting line equation in dynamic loading has been obtained: J=2NK0.5(subscript εFΔa.

The type of magnetic phase transition in Dy(subscript 1-xGd Co2 compounds is found shifting from first order to second order as Dy is substituted by Gd, which is supposed to be the main reason for the detraction of MEC.

磁熵变下降的主要原因是Gd替代Dy后化合物的磁相变由一级相变转变为二级相变。

A mathematical model and a program are developed to calculate neutron yields, energy spectrum and angular distribution of D^3 He reaction in a thick deuterium-titaniumTiD(subscript x target as incident deuteron energy lower than 1.0 MeV.

Under the experimental conditions, the evaluation of catalytic activity on direct decomposition of NO show that the presence of Cu is necessary for improving activity at 600~800℃ among La0.9Ce0.1Fe(subscript 0.8-x)Co0.2YO3(Y=Cu, Zn, Ni) series, and in which L.a0.9Ce0.1Fe0.7Co0.2Cu0.1O3 has the highest activity, the conversion of NO decomposition maintains 80% and nearly 100% at 750℃. H2-TPR result proves that the higher activity is related to the mobility of lattice oxygen which is beneficial to the reproduction of active site for NO decomposition.

在实验条件下，对NO的活性测试结果表明，L0.9Ce0.1Fe(下标 0.8-x)Co0.2YO3(Y=Cu， Zn， Ni)系列催化剂在600~800℃范围内，掺杂Cu的复合氧化物具有较高的催化分解活性，其转化率始终保持在80%以上，反应温度为750℃时，几乎100%转化。H2-TPR结果证明，其催化分解活性高的原因是Cu的掺入使晶格氧活动性增强。

Methods Fifty pairs of fresh colorectal cancer and homologous normal tissues were genotyped with Identifiler Kit and the mutations generated in cancer tissues were determined. The mutation rates, the numbers of locus matched without identical allele (A0), 1 identical allele (A1), or 2 identical alleles (A2) and the number of total identical alleles IA(subscript n were calculated. Frequency distributions of A0, A1, A2 and IA were compared among CR-N group, unrelated individual pairs and full sibling pairs. Discrimination functions were established for individual identification from tumor tissues with discriminatory analysis.
