In morpheme-based morphology, a null morpheme is a morpheme that is realized by a phonologically null affix (an empty string of phonological segments).

译文（不译，汉改高手是不懂的：在以词素为基础的字形学中，一个空白词素是由音韵学的空白词諁。

System.out.println("a.length="+ a.length); System.out.println("b.length ="+ b.length);// The handles inside the array are // automatically initialized to null: for(int i = 0; i nbsp;b.length; i++) System.out.println; System.out.println("c.length ="+ c.length); System.out.println("d.length ="+ d.length); a = d; System.out.println("a.length ="+ a.length);// Java 1.1 initialization syntax: a = new Weeble { new Weeble, new Weeble }; System.out.println("a.length ="+ a.length);// Arrays of primitives: int e;// Null handle int f = new int[5]; int g = new int[4]; for(int i = 0; i nbsp;g.length; i++) g = i*i; int h ={ 11, 47, 93 };// Compile error: variable e not initialized://!

句柄。此时，编译器会禁止我们对这个句柄作任何实际操作，除非已正确地初始化了它。数组b被初始化成指向由Weeble句柄构成的一个数组，但那个数组里实际并未放置任何Weeble对象。然而，我们仍然可以查询那个数组的大小，因为b指向的是一个合法对象。这也为我们带来了一个难题：不可知道那个数组里实际包含了多少个元素，因为length只告诉我们可将多少元素置入那个数组。换言之，我们只知道数组对象的大小或容量，不知其实际容纳了多少个元素。尽管如此，由于数组对象在创建之初会自动初始化成null，所以可检查它是否为null，判断一个特定的数组&空位&是否容纳一个对象。类似地，由基本数据类型构成的数组会自动初始化成零、null或者false。

函数audit_filter_type将审计事件值与规则域的值比较，返回逻辑比较结果，即审计事件值符合规则域的定义，则表示不需要查看这个审计事件，返回值为1，否则为0。

However, with multi-selected nulls, a separate Emit from Null compound is created for each null emitter.

然而，如果用户多选了NULL作为发射器的话则对每个null发射器都会创建一个各自的Emit from Null复合节点。

Dear Daughter, since thou claim'st me for thy Sire, And my fair Son here showst me, the dear pledge Of dalliance had with thee in Heav'n, and joys Then sweet, now sad to mention, through dire change [ 820 ] Befalln us unforeseen, unthought of, know I come no enemie, but to set free From out this dark and dismal house of pain, Both him and thee, and all the heav'nly Host Of Spirits that in our just pretenses arm'd [ 825 ] Fell with us from on high: from them I go This uncouth errand sole, and one for all Myself expose, with lonely steps to tread Th' unfounded deep, and through the void immense To search with wandring quest a place foretold [ 830 ] Should be, and, by concurring signs, ere now Created vast and round, a place of bliss In the Purlieues of Heav'n, and therein plac't A race of upstart Creatures, to supply Perhaps our vacant room, though more remov'd, [ 835 ] Least Heav'n surcharg'd with potent multitude Might hap to move new broiles: Be this or aught Then this more secret now design'd, I haste To know, and this once known, shall soon return, And bring ye to the place where Thou and Death [ 840 ] Shall dwell at ease, and up and down unseen Wing silently the buxom Air, imbalm'd With odours; there ye shall be fed and fill'd Immeasurably, all things shall be your prey.

" 他说罢，母子俩大为高兴，"死"一听说有这样可以吃饱的地方，不觉微笑露出了狰狞的牙齿，预祝自己的肚皮将交好运，邪恶的母亲也同样欢喜，这样对她父亲说： V2：她说罢，聪明的魔王便警悟，立刻放温和些，这样委婉地答道，"亲爱的女儿，你既然叫我父亲，又把俊美的儿子指给我看，这是我在天上和你嬉游时的纪念品，当初的欢喜、甜蜜，今天已不堪回首，都只因这不可预料的不幸变故。要知道，我这次来不是要同你们敌对，而是要把你们和一切为正当的权利而武装起义，并从天上坠落的天使军的精灵们解放，从黑暗和痛苦中解放出来。

Results of XRD,SEM,and UV-Vis indicated that ZnS nanocrystals can grow in and fill in the void of opal template,and SiO2 microspheres of templates are dissolved so as to form some three dimensional ordered porous structure and to form the inverse opal ZnS photonic crystals. Compared with opal templates,ZnS-opal and inverse opal ZnS photonic crystals assembled with SiO2 spheres in the same diameter show good optical properties and exhibited photonic band gap. The photonic band gap position of inverse opal ZnS moves towards UV area compared with opal and ZnS-opal.

结果表明：溶剂热法多次充填可使ZnS纳米晶在模板密堆积形成的空隙中均匀成核；经过酸处理的ZnS-opal中SiO2微球溶解、坍塌，形成蜂窝状三维有序介孔和反opal结构ZnS基光子晶体；相同粒径SiO2微球组装的opal模板、ZnS-opal以及反opal结构ZnS光子晶体均表现出光子带隙特性，但反opal结构ZnS光子晶体带隙位置相比前两者发生了蓝移。

G.E.Hubb root is from 0.20mm to 0.50mm, and 95% roots, diameter is thinner than 0.40mm. The total surface areas of roots is 10139.68cm^2, and the surface areas of roots is about 2 to 3 times to soil surface areas in the surface layer. Enlacing sod concretion to soil profile of Eulaliopsis binata G.E. Hubb root and the gigantic adsorption to soil grains of root surface are the mechanism why Eulaliopsis binata G.E. Hubb can reduce null and water loss significantly. The monitoring result from 2003 to 2004 indicates that, when the gradient is 12 degrees, the runoff rate of planting Eulaliopsis binata Retz. G.E. Hubb completely after changing slope land to ladder (PECC, so as the follows is only 49.90m^3/hm^2?yr. and the soil loss rate is 155.78kg/hm^2?yr, however, the runoff rate of fanning and being not change slope land to ladder is 314.29m^3/hm^2?yr that is 6.30 times to PECC ,and the soil loss rate is 3322.50 that is 21.33 times to PECC; When the gradient is 24 degrees, the runoff rate of planting eulaliopsis binata G.E, Hubb in the ridge and border slope land after changing slope land to ladder is 248.04m^3/hm^3?yr and the soil loss rate is 612.00kg/hm^3?yr. the runoff rate of PECC is only 42.44m^3/hm^2?yr and the soil loss rate is 153.75kg/hm^2?yr, however, the runoff rate of ENC reaches to 785.73m^3/hm62?yr that is 3.17 times to PERBC and 18.52 times to PECC, and the soil lose rate reaches to 37503m^3/hm^2 yr that is 61.33 times to PERBC and 244.12 times to PECC.

蓑草根系平均直径0.20~0.50mm， 95%的根系平均直径小于0.40mm，根系总表面积10139.68cm^2，在土壤表层根系表面积高达土体表面积的2~3倍，根系表面对土壤颗粒的巨大吸附作用是蓑草显著提高土壤抗侵蚀能力的另一个重要原因。2003~2004年的监测结果表明，在12度坡度情况下，坡改梯后净作蓑草年径流量仅49.90立方公尺/hm^2，年土壤流失量为155.78kg/hm^2，而未坡改梯且农作情况下，年径流量314.29立方公尺／hm^2为前者的6.30倍，年土壤流失量3322.50Kg/hm^2为前者的21.33倍；在24度坡度情况下，坡改梯后土埂及边坡种植蓑草、坡面农作年径流量248.04立方公尺/hm^2，年土壤流失量612.00kg/hm^2，坡改梯后净作蓑草径流量42.44立方公尺/hm^2，土坡流失量l53.75kg/hm^2，而未坡改梯且农作情况下年径流量高达785.73立方公尺/hm^2，分别为处理1的3.17倍，处理2的18.52倍，年土壤流失量高达37503kg/hm^2，分别为处理1的61.33倍，处理2的244.12倍。

The topographical parameters have been analyzed by taking into account the thermal effect during the friction process. As the results, three kinds of typical topographical features have been observed for the worn surfaces of C G iron with various P content. Namely, C G iron with 0.05% P, 1.30% P, and 0.70% P show worn surfaces characterized by groove ridge, peak pits and their combined topography. The C G iron specimen with peak pits type worn surface topography showes the lowest wear rate and highest friction coefficient, while that with groove ridge type worn surface topography shows the highest wear rate and lowest friction coefficient. The groove ridge type worn surface has a relatively large value of surface height deviation and void volume ratio and negative large value of skewness, which is contrary to the peak pits topography.

结果表明：度销磨损表面主要呈现犁沟型、孤岛型及二者的混合型3种形貌特征，其中具有孤岛型磨损表面形貌特征的试样的摩擦系数较高，磨损率较低；而具有犁沟型磨损表面形貌特征的试样的摩擦系数最低，磨损率最高，分析表面形貌参数发现：犁沟型表面形貌具有最大的表面高度偏差和表面空隙率及高负值的表面高度分布参数；而孤岛型表面形貌的表面高度偏差和表面空隙率最小，表面高度分布参数为高正值。
