Trichogramma showed high control efficacy on cotton bollworm eggs after three times of release both in the second and in the third generation bollworm periods. The parasitism on the second and third generation bollworm eggs were 66.0%-70.7% and 76.0%-81.2%, respectively, which were significantly higher than that in the control (second generation: 7.0%-12.3%, third generation: 5.2%-7.4%). And the injury rate of cotton buds and bolls in the second and third generation bollworm were 2.2% and 3.1%, respectively, which were significantly lower than that in the control (second generation:8.5%, third generation: 20.9%). In the second generation bollworm period, number of bollworm eggs or larvae in the Trichogramma released cotton field did not differ to that in the chemically controlled field. But in the third generation, there were significantly less bollworm eggs and larvae in the Trichogramma released cotton field. There were more predators in the Trichogramma released cotton field. These results indicated that cotton boll worm in the transgenic insect-resistant cotton field can he effectively controlled by mass-releasing of T.

It is shown that maximum temperature value of the field's will rise while the Mach number increases. After the Mach number exceeds one, a clear bowshock is obtained in the simulation result, and the Mach angle decreases along with the Mach number. Those are consistent with theoretical results. While the Mach number is 3.5, even the radome inside is adiabatic, the maximum temperature is below 1000K. So the CVD diamond thick film radome can meet practical requirement of flight at 3.5 Mach number.
研究发现,随着马赫数的增加,温度场中最大温度值也随之增大;在马赫数大于1时,会产生明显的弓形激波,且激波的锥角随马赫数增加而减小,这与理论结果相一致;当马赫数为3.5时,即使在头罩内壁绝热条件下,温度场中最高温度值也在1000K以下,表明CVD金刚石厚膜可以满足Ma=3.5的实际飞行要求。

The ground states properties of Ne-isotopes were calculated with Relativistic mean field theory. Compared with the experimental datas, its discovered that the nucleus properties chang regularly with the changes of neutron number when the proton number is even. The results proved indirectly that even nucleus has no direct influenced on another kind of nucleus. Besides, the applicability of Relativistic mean field theory in this region was tested.

5Under powerful offensive denfense,failing in resolving the offending problems is one of the leading reasons that it lost in the world men ' s basketball championship;the quantity of the fast attacks from chinese team lags behind a lot,compared with the opponents.Moreover,the difference of the quantity of success,the gap of score and fast attacks after stealing is very obvious; scoring could only be attributed to receive and shoot,play by oneself and free throw.Scoring method is simple and unscattered;strategic offenses lag behind the opponent obviously.Both free throw after active offense and rebound control could not defeat the rivals.The stealing and offense succeeding percentage also fall behind. The offense efficiency lags more behind;the number of two – piont shot lags behind the opponent while the field goal percentage ranks a little higher than opponent.The number of three-point shot is similar, but the field goal percentage is obviously different;chinese team ' s front court rebound falls behind the opponent apparently.However,the second offense scoring is a little higher;chinese team ' s assists lags behind a lot;chinese team ' s stealing lags behind a lot;chinese team ' s turnovers distingguish a lot with opponents.
