  1. The control of beam halo - chaos becomes a critical problem in the development of high intensity accelerator. efforts to remove the halo by collimation have been largely unsuccessful since the halos almost always regenerate. the mechanisms of halos are complex, such as nonlinear resonances and chaotic behavior etc. considering this, professor fang jin - qing who works in china institute of atomic energy pointed out that the theory of chaos control can be used to control beam halos. he presented the method to control halos by using nonlinear functions, which means nonlinear function g is added to the right of ion radial self - edlctric force equation and some nonlinear function are selected to control beam halos in simulations. in paper [ 69 ], controllerg = - 0. 15sin ( rmax - am ) 2 was used and the halo intensity was decreased to 0. 1078, the halos are removed partly

    束暈?混沌的控制是新一代強流加速器研製的關鍵問題，隨著強流離子束應用前景的日趨廣闊而日益成為研究的熱點。傳統機械限束器因無法解決束暈的再生而收效甚微，因為束暈的形成有著其內在動力學機制?非線性共振以及混沌等。基於此，中國原子能科學院研究員方錦清將混沌控制的理論和方法開創性的運用於束暈?混沌的控制上，提出了控制束暈?混沌的非線性控制策略，即在粒子徑向所受束自生場力方程的右邊加上非線性控制函數g ：並選取一些非線性函數如等進行了控制的模擬研究，將束暈強度控制在0 . 1078左右，取得了初步的控制效果。
  2. When both genes were co - expressed in e. coli, the activity of ppsa varied from 2. 1 - 9. 1 fold comparing to control, but the activity of tkta was relatively stable ( 3. 9 - 4. 5 fold ). whatever the two genes were expressed respectively or cooperatively, both could promote the production of dahp, the first intermediate of the common aromatic pathway, but co - expression was more effective on forming dahp and screened ppt - and ptp - as more effective. the results demonstrate that co - expression of ppsa and tkta can improve the production of dahp, and what ' s more, when multigenes co - expressed, the recombinant which has coordinated enzymes activity is optimum

    莽草酸途徑的最優化和整體調控基因csra的敲除正是上述改變的分子基礎，同時也為三種芳香族氨基酸的基因工程菌的構建打下了基礎; 7 .在國內外首次實現了共同途徑限制性底物關鍵酶ppsa刁無『及arog與分支途徑關鍵酶基因phea的串聯高效表達，所構建的重組質粒ptga ，其ppsa 、 tkta 、 arog 、 cm和pd的酶活分別比對照提高了3 、 2 、 2 ， 5 、 4 、 2 . 3倍，且其酶活比較協調一致; 8 .將ptga導入到篩選的基因敲除和基因替換菌株大腸桿菌31884 c甲b中，搖瓶發酵證實比以往所構建的基因工程菌株具有較高的phe產量和糖轉化率率，分別為0 . 448 %和22 . 4 % 。
  3. Using plots with water and fertilizer fully controlled, the effect of photosynthetic characteristic and yield under different treatments of water and fertilizer coupling was investigated. the result showed that photosynthetic rates are different among treatments of water and fertilizer coupling, and the change of stomatal conductivity is the same as photosynthetic rat. there is almost no influence on evaporation rate and cellular co2 concentration the combination of fertilizer and manure under natural rainfall is beneficial to the maintenance of photosynthetic rate during grain filling, thus results in highter yield and good quality. however, the coupling of fertilizer and manure with sufficient water results in the decline of photosynthetic rate and stomatal conductivity, the yield decreased indicating there has a balance ratio between water and nutrients ( fertilizer and manure ) supply. the study proposed that the optimum management to exploring yield and qlality potential is the combination of fertilizer and manure application with no irrigation

    利用可精確控制水分條件的水肥平衡場，在不同水肥耦合處理的條件下，研究了水肥耦合對玉米光合特性及產量的影響，結果表明:不同水肥耦合處理的條件下，玉米的光合速率有所不同，氣孔導度的變化與光合速率的變化表現基本一致，而對蒸騰速率、細胞間co2濃度影響不大.其中，在自然降水條件下，有機肥和無機肥的配合，有利於玉米子粒灌漿期維持較高的光合速率，表現出良好的產量潛力.充足水條件下，有機肥和無機肥的配合，光合速率及氣孔導度表現較低，表現產量有所下降，說明供水量與施肥量之間有一個平衡系數.表明黑龍江省北部黑土區自然生態條件下，為充分發揮玉米的產量潛力，最佳的管理措施是增施無機肥和有機肥的配合
  4. Without grids, the interaction effect among neighboring particles can be simulated by means of the kernel function, based on which the governing equation is discretized by establishing the smoothing model, the gradient model and the second - derivative model ( i. e. the laplacian model )
