植物病虫害防治有各种不同的方法,概括地说,有化学的和非化学的方法,非化学防治包括规章制度的管理、检疫、生物防治、耕作防治和物理防治.现在,商业上并不提倡非化学防治.然而,在栽培上由于使用各种抗病虫的作物品种,因而生物防治方法得以保持.但在茶树方面,已培育出的抗病虫害的茶树品种极少,所以化学防治从来就很重要.

the Heavy Flavor Averaging Group （HFAG） is an international collaboration of physicists from experiments measuring properties of heavy flavored particles. HFAG calculates for the HEP community world average values of quantities such as lifetimes, branching fractions, form factors, mixing parameters, and CP-violating asymmetries. Most parameters concern decays of B and D mesons and τ leptons, and many are related to elements of the Cabibbo-kobayashi-Maskawa （CkM） quark mixing matrix [1,2].

the occurrence of per-and polyfluoroalkyl substances(PFAS)in water cycles poses a challenge to drinking water quality and *** order to counteract the large knowledge gap regarding PFAS in German drinking water,89 drinking water samples from all over Germany were collected with the help of residents and were analyzed for 26 PFAS by high-performance liquid chromatography with tandem mass spectrometry(HPLC-MS/MS).the 20 PFAS recently regulated by sum concentration(PFAS_(∑20)),as well as six other PFAS,were quantified by targeted *** all drinking water samples,PFAS_(∑20 )was below the limit of 0.1μg/L,but the sum concentrations ranged widely from below the limit of quantification up to 80.2 ng/*** sum concentrations(PFASP4)of perfluorohexanesulfonate(PFHxS),perfluorooctanesulfonate(PFOS),perfluorooctanoate(PFOA),and perfluorononanoate of 20 ng/L were exceeded in two *** most frequently detected individual substances were PFOS(in 52%of the samples),perfluorobutanesulfonate(52%),perfluorohexanoate(PFHxA)(44%),perfluoropentanoate(43%)and PFHxS(35%).the highest single concentrations were 23.5 ng/L for PFHxS,15.3 ng/L for PFOS,and 10.1 ng/L for *** regionally elevated concentrations were identified,but some highly urbanized areas showed elevated *** of substitution PFAS,including 2,3,3,3-tetrafluoro-2-(heptafluoropropoxy)propanoate and 2,2,3-trifluor-3-[1,1,2,2,3,3-hexafluor-3-(trifluormethoxy)propoxy]-propanoate(anion of ADONA),were very low compared to regulated *** most frequently detected PFAS were examined for co-occurrences,but no definite correlations could be found.

Reported in this paper are precise INAA data on 19 L and LL chondrites (7 Chinese chondrites and 12 from other countries). the L and LL chondrite data normalized to Mg and to CI chondrite indicate that for several lithophiles (V, Al, Cr and Mn), the extent of scatter is low, similar to that observed in carbonaceous chondrites. the average concentration of siderophiles in the LL group is lower than that in the L *** the basis of olivine composition and atomic ratio (Ir/Au), we reclassify the five previously labeled L ehondrites as LL members. the atomic ratios of Ir/Au in the LL chondrites are lower than those in the L chondrites (the division is set at an Ir/Au ratio of 2.5). the atomic ratio of Ir/Au appears to be a useful classification parameter for ordinary chondrites. therefore, it can be considered as a new taxonomic parameter. Of the elements studied, Br, a high volatile, seems most likely to show thermometamorphic effects, depending on petrologic types. the concentration of bromine and the

1 Summarythe 5-year-survival rates of surgically treated patients are varying and depend on UICC stages/substages with remarkable variations in between published reports, surgical hospital units, individual surgeons, and continents. these variations may be due to surgical techniques, training status, hospital and individual case volume, but also on referral patterns, and statistical evaluation methods. Survival time and cure rates are significantly improved by modern adjuvant chemotherapy in colon cancers UICC Ⅲ and in substages of UICC Ⅱ (e.g. UICC Ⅱ B) by 5%-16%, and adjuvant radiochemotherapy in rectal cancer by 10%-14% when compared to surgical controls. In three modern colon cancer trials standard adjuvant chemotherapy was further improved by increasing the survival rates, e.g. from 59% to 71% in stage Ⅲ and IIB patients. In rectal cancer neoadjuvant radio(chemo)therapy decreases local relapse rates vs. postoperative adjuvant radio(chemo)therapy. Since surgery in rectal cancer has also been significantly improved by total mesorectal excision (tME) and better surgical training, the indications and methods for multimodal therapy have changed from UICC Ⅱ+Ⅲ to more individual criteria. Molecular and genetic factors, such as thymidylate synthase (tS), microsatellite instability (MSI) or loss of chromosome 18q/DCC might have an independent impact on prognosis in the spontaneous course, but could also help to individually select colon and rectal cancer patients and treatment protocols for multimodal therapy. thus, surgery and multimodal therapy has become very complex, needs regularly be updated in competent reviews, and should be conducted in specialized centers of multi-and interdisciplinary excellence.
