The heterosis of grain hardness of interspecific hybrid between common wheat and spelt wheat or club wheat were usually negative except that of hybrid between common wheat variety Nongda 3226 and spelt wheat or club wheat.

普通小麦与斯卑尔脱小麦的种间杂种、普通小麦与密穗小麦的种间杂种的籽粒硬度均表现负优势，但农大3226所配的组合的籽粒硬度多为正优势。

The heterosis of spike number per plant and grain number of main spike were stable in the intervarietal crosses between years, and so were the grain number of main spike in the crosses of common wheat with club wheat, and were the 1000-grain weight in the crosses of common wheat with spelt wheat.

普通小麦品种间杂种每株穗数优势和主穗粒数优势年度间表现稳定；普通小麦与密穗小麦的种间杂种主穗粒数优势以及普通小麦与斯卑尔脱小麦的种间杂种千粒重优势两年均表现出明显的杂种优势，且幅度相近，其他性状年度间差异较大。

The average heterosis of spike number per plant and 1 000-grain-weight were high and obviously related to yield heterosis at 0. 01 and 0. 05 level, respectively; the average yield heterosis of F1 hybrids between common wheat and club wheat was 77. 19%(ranged from-2. 18% to 143. 42%), the average heterosis of spike number per plant and spike grain number were high and both was also obviously related to yield heterosis at 0. 01 level.

结果发现：小麦种间杂种在产量上具有明显的杂种优势，其中斯卑尔脱小麦与普通小麦所配的30个种间杂交组合产量杂种优势平均为109.24%(43.14%～187.96%)，单株穗数及千粒重平均优势较大且与产量优势的相关分别达极显著水平和显著水平；密穗小麦与普通小麦所配的30个种间杂种的杂种优势为77.19%(-2.18%～143.42%)，单株穗数和主穗粒数优势较大且与产量优势的相关均达极显著水平。

The SCA effect was important in the heterosis of the spike number per plant of the intervarietal hybrid, the SCA and GCA were both important in the heterosis of the grain number of main spike of the intervarietal hybrid; the SCA effect played an major role in the heterosis of the spike number per plant of the interspecific crosses of the common wheat and club wheat, the SCA effect played an major role in the heterosis of the 1000-grain weight of the interspecific crosses of the common wheat and spelt wheat.

普通小麦品种间杂种每株穗数杂种优势中，特殊配合力所代表的非加性遗传效应起了主要作用，而主穗粒数杂种优势中一般配合力、特殊配合力所代表的加性、非加性遗传效应所起的作用相当；普通小麦与密穗小麦种间杂种主穗粒数杂种优势中特殊配合力所代表的非加性遗传效应起了主要作用；普通小麦与斯卑尔脱小麦间杂种千粒重杂种优势中特殊配合力所代表的非加性遗传效应起了主要作用。

And opposite, the downstream unsubstitutability's market enhancement , advantage of status of products strengthen the unsubstitutability and market advantage status. These forms of expression of limiting the competition behavior are as follows, utilize the market advantage position, set up and strengthen the barrier of the application program or operating system procedure barrier, utilize OEM to put the software and squeeze the rival in advance, discriminatory pricing policy, pairing unsalable up with goods that sell well or trussing up and sells the behavior , lures the ICP into adopting specific technology, and technology the can only in specific customer serve and function, with the way of trussing up with the ISP.The copyright ill-useing happens frequently .

软件产业中的不正当竞争行为大多都与软件著作权的滥用有关，并且通常与滥用市场优势地位结合在一起，既有横向限制竞争行为，又有纵向限制竞争行为，且以纵向限制竞争行为为主，常表现为一种产品的不可替代性、市场优势地位往往会加强其上、下游产品的不可替代性和市场优势地位，而相反，其上、下游产品的不可替代性和市场优势地位的增强又进一步强化这种产品的不可替代性和市场优势地位。

Walchia ewingi Fuller（66.2%）, Laelaps turkestanicus Lange（38.5%）, Paradoxopsyllus custodies Jordan（42.9%）and Hoplopleura pacifica （80.1%）were the most predominant species of chigger mites, gamasid mites, fleas, and sucking lice, respectively.

攸氏无前恙螨为优势恙螨种，占恙螨总数的66.2%(710/1 072)；土尔克厉螨为优势革螨种，占革螨总数的38.5%（396/1 029）；绒鼠怪蚤为优势蚤种，占蚤总数的42.9%（9/21）；太平洋甲胁虱为优势吸虱种，占吸虱总数的80.1%（217/271）。

The 1000-grain weight heterosis was mainly due to the grain fresh weight heterosis at 12 DPA and 22 DPA that the intervarietal hybrid had, and also due to its promotion of 2 kinds of hormone IAA and CTK 12 DPA, the IAA function extended to 22 DPA.

品种间杂种也具有一定的千粒重杂种优势，这与12天、22天籽粒的鲜重优势有关，籽粒发育早期（12天）2种促进型激素IAA和CTK促进籽粒生长，与其获得较大的鲜重优势有关，IAA的促进作用可延伸到22天。

Results Eight species belonged to three families, two orders of rodent animals and seven species of fleas were found in this area. Rattus losea and Xenopsylla cheopis were dominant species, R.flavipectus , R.norvegicus , Suncus murinus , and Banolicota indica were familiar species.
